Peanuts meets Prehistoric Planet

Peanuts meets Prehistoric Planet is an 2023 British–American direct-to-DVD live-action computer-generated imagery nature documentary film directed by Adam Wingard and with Jon Favreau and Mike Gunton as the executive producers and the famous and legendary Sir David Attenborough as the narrator, as well as the guiding voice for the main characters. The film is a crossover between Peanuts and Prehistoric Planet created by Charles M. Schulz and BBC. The series follows Charlie Brown and his friends as they go back in time and explore the Late Cretaceous period, 66 - 65 million years ago, and observe dinosaurs and other prehistoric animals that lived in this particular era.
==Synopsis==
Legends collide in this epic crossover between two famous celebrities, Peanuts and David Attenborough. In this series, Charlie Brown, Snoopy & their friends are greeted by David Attenborough, who takes them all under his wing into understanding a lot more than what we already know so far about dinosaurs and other prehistoric creatures that lived alongside them.
==Plot==
=== Introduction: ===
One day, Charlie Brown and Snoopy are walking down the sidewalk, when they notice something rustling in the bushes of the edge of the forest, which reveals itself to them as a young T-rex, along with its siblings. Just then, a full-grown adult male Tyrannosaurus rex, who is the youngsters' father, appears, and they come running up to him, and he nuzzles them, and Charlie Brown and Snoopy are amazed to see this, as they have never before even seen a real live, living, breathing, dinosaur, or even a whole family of which, right in front of them or their own eyes.
They then also notice other types of species of Late Cretaceous dinosaurs all around them as well, and then meet a smartly-dressed man, who, to be precise, is the great, famous and legendary, Sir David Attenborough, who introduces the little dinosaur family to them as one of the most famous and legendary predatory dinosaurs of all; Tyrannosaurus rex. An animal to spark the imagination for all of us. He also tells them that a full-grown T-rex is the planet's most powerful predator, but this one is just being father to his offspring. When Charlie Brown eventually asks what kind of an animal was T-rex, like what did it look like, at least on the outside, or how did it live, David Attenborough then tells him and Snoopy that, now, scientific research has answered such questions, and not just about T-rex, but, also, the other species that lived alongside it. And that the latest imaging technology enables us to bring them all to life. Charlie Brown and Snoopy are intrigued by this, and even more so when David even asks them if they would like go back in time to the Late Cretaceous period, 66 - 65 million years ago, to see them in real life for themselves.
Charlie Brown then summons his little sister, Sally, and then calls in and summons all his friends, including Heather and Janice, to assist him and Snoopy, to which they all accept, although Lucy is a little bit, though secretly, reluctant at first.
=== The Adventure Begins: ===
After the gang has finished packing everything they need for this adventure, David Attenborough tells all them that he will be both their narrator and voice guide throughout their entire journey and then gives out a mixed-combined monologue of both of his introductory speeches from both seasons of Prehistoric Planet, and ends it all by saying "This is our Prehistoric Planet, Charlie Brown." to which, Charlie Brown smiles at him for, before they all officially head into the time portal that is set to take them back to the Late Cretaceous period, 66 - 65 million years ago.
=== Coasts: ===
When they arrive, they find themselves on the southern shores of the great inland sea that splits North America, the legendary Western Interior Seaway; the place where their adventure will truly begin, and they also notice the tracks of the land's top predator. They then realize that, since the creator of the footprints is nowhere to be seen on land, the tracks themselves, however, lead out towards the sea, as if the track-maker went into the ocean and swam out into it. To find that out for sure, Snoopy and Fifi unpack their trusty inflatable raft, and they all then put on their swimwear, load up their raft, and set out to find the creature who made the footprints and follow it. In the sea, after several minutes of paddling, the gang, at last, find what they've been following, and are surprised and amazed at what they are seeing; a Tyrannosaurus rex taking a swim. Sally says that she never thought that dinosaurs could actually swim, and so, David Attenborough (as their voice guide) tells her and the rest of them that hollow, air-filled bones and powerful hind limbs make T-rex very effective swimmers. With Charlie Brown and Linus speculatively saying that pretty much all dinosaurs are very effective swimmers. As they paddle alongside the swimming dinosaur, they then notice five young T-rex following closely behind. Their voice guide tells them that this is an adult male, with his young family, just like the one that Charlie Brown and Snoopy met back in the present before their journey began, and that his offspring are now just old enough to follow him on a journey to one of the many offshore islands that fringe this coast, which is exactly where they're heading to for some reason.
He also tells them that it's a short enough crossing, just about a short distance from the coast, but it can still be a dangerous one. And that just goes to show when they all notice something else in the water that has taken notice to them, a Mosasaurus, who David tells the kids is a giant marine lizard, about 10 feet longer than a tyrannosaur, and weighing over 15 tons. He also mentions that it's the largest marine predator on the planet, as the father Tyrannosaurus briefly looks down in the water to gauge how close the Mosasaurus is, prompting him and his five children to swim faster, and the gang to paddle faster. They all knew that turtles are normally on a mosasaur's menu, but either they or the young of this brood would make a welcome snack. The Mosasaurus, aware that the adult T-rex, being an apex predator like it, is still capable of attacking and fighting it, and also defending itself, in the water very effectively, thus, making it too dangerous for a mosasaur meal, sets its sights on the one of the T-rex hatchlings lagging behind the rest. David Attenborough tells the gang that an adult T-rex, even in water, could still attack, fight, and defend itself very effectively, thus, making it too dangerous for a mosasaur meal, but the young must stay close. As they all approach the shore, the Mosasaurus is closing in on them, and the hatchling that is lagging behind screeches more as its panic grew greater, until it got grabbed by the Mosasaurus and dragged down beneath the waves. The Mosasaurus then flicked its tail and turned around and away just as the gang and the rest of the Tyrannosaurus family reached the coast of the offshore island. But the kids had noticed what has happened and are shocked. At the same time, the father Tyrannosaurus turns and faces the sea, realizing that one of his five offspring was caught and eaten by the Mosasaurus.
David Attenborough (as the narrator) explains that, like any dinosaur, Tyrannosaurus rex often lose at least two-thirds of their original brood of 15 or so in the first year. Fifi is saddened by this, but Snoopy comforts her. The kids comfort the male T-rex and his remaining youngsters. At first, there were five, but now, there are only four. With nothing more than can be done, the gang deflate and pack up their raft and climb up onto the father Tyrannosaurus' back to hitch a ride on, as he and the rest of his young continue down the shoreline of the beach. The island offers safety and the promise of food. Giant, 2-ton turtles, who they pass by, are here to nest. But this is the one that has drawn him here. It's dead, and the tyrannosaur has smelled its rotting body. Marcie theorizes that he must've smelled it from up to about 5 miles away from somewhere back on the mainland of North America. If he can just get to the underbelly, he will have over two thousand pounds of easy meat. The father Tyrannosaurus vocalizes as he manages to flip it over with his super T-rex strength, exposing its underside and underbelly, and he then proceeds to feed upon it. 
When David mentions that T-rex has the most powerful jaws in nature, and can bite with the force of over five tons, Charlie Brown accurately notes that that's up to about 100,000 pounds per square inch. The young are keen for a taste, but he's not sharing it, however, as he drives them off with a light growl, intending for them to learn how to hunt for food on their own. And so, it's time for them to learn to hunt for themselves. And more so, the gang hop off the father Tyrannosaurus to join his remaining children. The beach, however, doesn't look very promising. The four surviving juveniles at first simply run around the beach, playing around with the kids, Snoopy and Fifi, as well as Woodstock and his pals, and even playing around with, and riding on, a giant turtle at one point. But as the evening approaches, things start to change. The turtles eggs buried in the sand hatch, and the baby turtles make their way to the sea. The young T-rex have been brought to an ideal training ground. Hatchling turtles are the perfect size for a novice to tackle. One young tyrannosaur at first plays around with these turtles, stomping some of them into the sand, since it pays for any hunter to be inquisitive, and then getting scared off by the waves as they take a turtle hatchling into the sea. For these youngsters, there's a lot to learn. And there's enough food here to satisfy both parent and young. Though their parent still refuses to share the dead turtle he's eating, so one of the juveniles decides to go after a baby turtle, only to be fought off by one of its siblings, which steals and eats the baby turtle for itself, leading to a game of chase, which goes to show that if all else fails, you can always steal supper from someone else. The rest of the newly-hatched turtles getting swept by the waves into the sea. Charlie Brown and his friends then bid their T-Rex friends farewell before leaving the island and moving on. 
While the gang is traveling along the coastlines of the continents, whilst leaving the Western Interior Seaway, their voice guide tells them that across the globe, these shallow coastal seas cover an area of 25 million square miles, far more than even the largest continent. And that, combined with the richness of the waters, makes them very important habitat. He also notes that wherever land meets sea, nutrients rise from the deep, fueling an abundance of life. And that it's especially rich here in the North Atlantic, where they are now, where huge shoals of fish come close to the shore. 
The gang then find themselves washing up onto the shores of Northern Africa, where their voice guide says that one kind of animal thrives in such places and forms immense colonies. The gang notice and realize them as flying reptiles, pterosaurs. Their voice guide tells them that, here, on the beaches of North Africa, there are seven different species of them. A colony of one example, Tethydraco, is seen on a beach, and the Peanuts gang make their way through the colony, careful not to startle or even disturb them. When Violet and Patty wonder and ask why they are here, David explains that they come here to feed, to rest, and to raise their young. Since Tethydraco are well-adapted to spend their time on the ground, and not only make their nests here, but stay to protect their brood. And their young certainly need protection. For one good reason. One Tethydraco hatchling is seen wandering around, though its mother quickly ushers it back in place to keep it from wandering too far from the nest. The concerns of the parents are justified, for, wandering the beach, is an opportunistic predator, who the Peanuts eventually come face-to-beak with. The dagger beak of Phosphatodraco. A nine-foot-tall predator that stalks through these colonies, looking for a chance to snatch an unguarded hatchling. The Phosphatodraco looks down at the kids and their dogs and birds, but, though curious, doesn't seem all that interested in making a meal out of any of them, and so, Snoopy and Fifi hitch a temporary ride on him. The Tethydraco clack their beaks to keep the larger pterosaur away from their nests and chicks, though the Phosphatodraco remained undaunted, completely disregarding their warnings as it continued patrolling through their colony. 
But the gang's voice guide tells them that some pterosaurs are less well-adapted to life on land. And that they have a slightly different nesting strategy; they make their nests where they will attract less attention from predators. Isolated cliffs like these are ideal. So, they all head over on their raft to check it out and climb up the cliff walls to the near-very top. They then notice that beneath a pile of seaweed, something is stirring. A tiny Alcione hatchling, just a few inches high, and weighing less than two ounces. Other newly-hatched Alcione chicks emerge from beneath piles of seaweed. The kids help them by removing some of the seaweed that they might be stuck or caught in or that might be holding them back or down. Their mothers left the eggs here about two months ago. As they chirp, even more of them hatch and come out. Calling to each other synchronizes hatching; there is safety in numbers. By instinct, hundreds climb to the top of the cliff, along with their new larger friends, doing short test flights as their wings slowly form up. Hatchlings from hundreds of nests gather on the clifftop to prepare for their first flight. But their wings are still unformed. The bones of the long finger that supports their wing membrane must first straighten and lock together, and that will take some hours. But they can't stay here for long. Their bones are extremely light, up to 90% air, and that makes the effort needed to take off much easier. Even so, test flights are essential. There will only be one chance to get it right when the time comes to launch. Charlie Brown and them all take turns helping them out with practicing their test flights, with Woodstock and his pals as their instructors. The cliff edge creates updrafts, and they can help. The updrafts of wind formed by the cliff edge provide favorable conditions for them to fly all the way to their destination, the mainland. So, it pays to gather their facing into the prevailing winds and towards the mainland. But, even so, there is initially an air of hesitance, as no one seems quite ready to take the plunge. Until, at last, one youngster flies off and sets them all on their way, prompting the kids, Snoopy, Fifi and Woodstock and his pals to follow in their raft. They're not heading for the beach and its colony, but instead, they need to get to the mist forest that lies on the cliffs beyond the beach. 
Unfortunately though, the journey there is not straightforward, as the gang then notice something else flying; Barbaridactylus. Powerful predatory pterosaurs that normally catch fish, but the hatchlings are too good to miss. Sensing an easy meal, three Barbaridactylus swoop in and snap up some of the hatchlings in midair. One way to take evasive action is to simply fold their wings and drop. The juvenile Alcione fold their wings and drop, momentarily evading their predators at the cost of lost height. But losing height will make it harder for them to reach the forests. Some end up flying too low to the ocean, even close to the gang's raft, and are easily grabbed by the Barbaridactylus. As the group re-washes ashore, one unlucky Alcione hatchling crashes down on the beach, attracting the attention of one of the Phosphatodracos prowling the colony. The Tethydraco, and Peanuts gang, in horror, look on as the Alcione hatchling tries to stand up, while the opportunistic azhdarchid closes in on it, clacking its beak in satisfaction before grabbing the hatchling, devouring it as it screeched its last. A really-scared Fifi is comforted by Snoopy as the Tethydraco give one last glance as the predator swallowed and savored its meal, serving as a reminder to them of what fate could befall their chicks should they be left unguarded, before one, along with the gang, turned its attention back to the Alcione that are still airborne, trying to escape the Barbaridactylus. The gang then noticed one hatchling still being pursued by a Barbaridactylus, A lucky survivor from the first wave of hatchlings, still heading in the right direction. It manages to finally reach the cover of trees, prompting the predator to stop just short of the forest and fly off at last. Sanctuary. The gang is very relieved that the hatchling was able to escape into the trees of the forest. The survivor, among a few others, gather in the safety of the trees, joined by Woodstock and his pals, who fly up to check them over to make sure they're alright and unscathed, resting and flapping their wings as they watch the open ocean. Of the hatchlings that left the stack, few get as far as this. But for them, this forest offers all the shelter and food that a young pterosaur needs. The hatchlings also watch five adult Alcione flying across the ocean, giving them a glimpse of the future ahead of them. For the next five years, this will be their home, then, they will be large enough to join the adults catching fish out on the open ocean. Woodstock and his pals then say goodbye to their fellow baby pterosaur friends before rejoining the gang as they jump back into their raft and move on. 
As the group pushes further on along the coasts, their voice guide tells them that some marine animals that spend all their lives fishing out at sea must occasionally visit the coast for a very particular purpose. They wonder what what it is, and they eventually get their answer when Snoopy and Fifi put on glass scuba helmets and strap on air tanks, and then take the plunge. In the waters off the drowned continent of Zealandia, a long journey is coming to an end. From out of the blue appears a pair of a type of elasmosaurid plesiosaurs. These are Tuarangisaurs, a type of huge marine reptile nearly 30 feet long. The pair were a mother Tuarangisaurus and her baby. This female is accompanied by her calf, about six months old. At most, she'll have only one youngster every two years or so. It's a huge investment, and one that makes the bond between mother and young very important. They are both accompanied by Snoopy and Fifi, who hitch a ride on the mother Tuarangisaurus' back. And the rest of the gang follow them from behind with a satellite radar device that is able to detect a tracking device that Snoopy had attached to his air tanks. 
She has brought her young calf many miles to this one bay in particular. And they're not alone, as Snoopy, Fifi and the rest are about to find out. Tuarangisaurs come here from across the South Pacific. Males also gather here to display to females. The male Tuarangisaurus raise their necks vertically above the water in a very Whale and Dolphin spyhop-like position in a bid to impress females in the area. But for now, courtship is not the female's first priority, and the kids wonder why. So, they anchor their raft and leave Woodstock and his pals in charge of it, and then put on glass scuba helmets and strap on air tanks to join Snoopy and Fifi, as well as the female Tuarangisaurus and her calf. Needless to say, the minute the young Tuarangisaurus was seen by them, he was immediately adorned and hugged by the girls, all except Lucy, who was most exasperated, but could do nothing about it. This bay has something that few others can provide. Pebbles, that are particular smooth, hard, and rounded. They've been worn by the action of river water, but they're hard to find. Here, however, in the pool at the bottom of a waterfall, there are plenty of them. And the Tuarangisaurs can take their pick as they congregate, using their snouts to dig the ideal stones from the shallow floor of the coast. The gang are amazed by this, and even more so, when they witness what happens next. They then do something rather remarkable. They swallow them. They need the stones to act both as ballast and as gizzard stones, "gastroliths", which will remain in their stomachs to grind up their unchewed food. Charlie Brown, Linus, Heather, Janice, Sally, Marcie and Peppermint Patty recall witnessing this particular type of behavior in sauropod dinosaurs and modern birds, like Woodstock and his pals. 
The mother Tuarangisaurus leads her calf down to the stones at the bottom of the waterfall, intending for him to learn how to collect gastroliths. For a youngster, learning to swallow pebbles for the first time isn't easy. It takes a little practice. But it's also a chance for his mother to find a suitable mate amongst the males. As the calf struggles to learn how to properly pick up and swallow stones, his mother leaves him to it with his new friends and then proceeds to find a suitable male to mate with, engaging in courtship in the open waters. For the calf, at last, success. Now, he will swallow as many as he can, and, as he grows, he'll return here for more. After he finishes swallowing as many pebbles as he could, he playfully bumps Charlie Brown, and then Snoopy, to show how quite friendly he really is before he rejoins his mother. It's time for the family to leave the coast and head back out to sea to feed. And for the young Tuarangisaur, that is an important step on the road to adulthood. And so, the gang bid their Tuarangisaurus friends farewell before heading back to their raft and leaving the bay as well. 
The Peanuts soon find themselves in southern Europe, where the Atlantic meets the great legendary Tethys Sea, and coastal life perhaps reaches its greatest diversity. Rising sea level means that there are countless submerged islands covered with sponges, clams, and corals. And so, the kids and their canine companions anchor their raft and put on their scuba gear again, leaving Woodstock and his pals in charge of the raft again as they head underwater and into the reef to explore. The corals take advantage of the sunshine in these shallows, forming partnerships with algae that grow within their tissues. They collect tiny particles of food floating in the ocean currents. Myriads of these marine creatures encrust the solid rock. But they happen to find that one slab of rock here appears surprisingly bare. Beyond is a sheer drop-off and the deep sea, home to oceanic predators, such as an approaching old male Mosasaurus, whom the gang notice, and danger for unwary reef fish.
The Mosasaurus then arrives and settles down on the bare rock slab and gapes his mouth open. But this pycnodont fish has little to fear. Once the many inhabitants of the reef realize that the Mosasaurus wasn't there to eat, however, they begin to gather around him, allowing the kids and Snoopy and Fifi to get right next to the giant marine reptile. When they wonder what kind of Mosasaur he is, their voice guide tells them that this is Hoffmann's Mosasaur, Mosasaurus hoffmannii, the ocean's biggest and deadliest predator, but he's not here to eat, he's come to be cleaned. And the reef's inhabitants begin to clean him. David also tells them that Mosasaurs are giant lizards, and have both a lizard's forked tongue, and, during the mating season, a lizard's colorful skin. Now, it's time to shed old skin, with various fish and cleaner shrimps picking off scraps from the Mosasaurus' teeth as well as the old skin he was shedding off. And when you need to look your best, nothing but an all-over body scrub will do. The Mosasaurus then rolls around on the rock, allowing the fishes and shrimps to clean even his belly. Fish and shrimp pick scales shed from his body. When they were finished, the Mosasaurus then rolls back over and then pokes his head out of the water. Resting at the surface allows this sea-going, air-breathing lizard to fill his lungs, and relax.
Calm is restored, but it won't last for long.
Suddenly, from out of nowhere, something lunges at the Mosasaurus, frightening the gang, and catching him off-guard, and knocking him off his rock-lounger. The attacker: a second Mosasaurus. A rival, a younger male challenging for this territory. The Peanuts watch in horror as the younger rival grabs their friend by the neck while he's still disoriented in an attempt to pin him to the rocks. Both Mosasaurs then retreat and circle back towards each other, barely colliding head-on, with the older male managing to halt the younger male by grazing his left side. The two pull back and collide again, with the younger male grabbing his rival's snout, trying to pin him down. The old male is heavier, over 15 tons, but his rival is more nimble. As the old male struggles, the young male continues to assault him, momentarily grabbing his right front flipper, but mostly attempting to crush his neck and bash him against the rocks. When they are as evenly matched as this, these fights can be lethal. David Attenborough tells the gang that Mosasaurs have been found with the shattered teeth of rivals embedded in their skulls. Momentarily fending off his rival by breaking free and then biting his neck and pushing him down in turn before rushing up to the surface, the old male snatches a breath. With his strength replenished, the old male the grabs his rival by the neck, and then by the snout. Now, he has the advantage. The kids, Snoopy and Fifi then went over the the edge and watched as the old male started dragging the young male down the walls of the submerged island, all the way down to the depths, where clouds of sand obscure both of them from view. By dragging his rival down, he could drown him. For a moment, all is quiet. And the gang can't see either of them and wonder where they are The younger male eventually emerges from the sand clouds, swimming away, with no sign of the older male anywhere. Then, at last, the old male emerges victoriously upward from the sand clouds and depths, having won the battle, triumphantly returning to the surface to breathe once again, with the kids, Snoopy and Fifi grabbing and holding onto him. The older male resurfaces and leisurely keep his head above the water, with his smaller friends patting him for a job well done, amazed by how much fight he still has in him. The old male has triumphed. For now, at least, this reef is still his territory. Eventually, the gang say goodbye to their Mosasaurus friend before leaving and heading back out in their raft. 
A crescent moon off the coast of North America, where the gang is now. The calm, dark nights that follow trigger a rare and beautiful event. So, the gang anchor their raft ashore and put on their scuba gear again, leaving Woodstock and his pals in charge of it again, before wading and then swimming out into the dark waters of the ocean. And much to any of their surprise, tonight, even in the deep, there is light. Glowing Ammonites rise from the abyss. Franklin notefully mentions that, from what they learned from school, Ammonites are mollusks, related to octopus and squid. And voice guide notes that these Scaphitids are no bigger than a human hand. Sally mentions that she also like to call Ammonites, "Adorbs", saying that they're impossibly cute. For weeks, they've been gathering in the coastal depths. The kids wonder why they've come up from the ocean depths, and their voice guide says that, in the deep, these lights may help lure plankton as food. But tonight, they serve a different purpose. They've been drawn to the surface to mate. And soon there are thousands in each shoal. Neighbor triggers neighbor, creating waves of bioluminescence, causing Snoopy and Fifi to "ooh" and "aah" in amazement. Marcie states that they have complex nervous systems, controlling light-producing cells in their skin called photocytes. Soon, some females begin to arrive, attracted by the light show of bioluminescence. The males then jostle for a place around the larger females. Clues from their displays tell her who is the fittest and who is the best mate. As couples entwine, they coordinate their light displays. Snoopy and Fifi watch closely as a female approaches a male and they soon lock tentacles before they then start flashing in unison. If he can't match her precise rhythm, he'll be rejected. But there is perfect synchrony between them. Then, the two Ammonites separate. This pair will now spawn and help produce the next generation. After fertilization, the females enter the shallows to release their eggs, with the Peanuts gang following them. As they also know, as with most cephalopods, breeding is the final act of their short lives. By morning, and the moment the gang come back ashore, these lights will have flickered and died. On the shoreline, countless Ammonites line the shoreline as lifeless as the Peanuts. This magical night will be their last. The gang is sad to see them go, but at least they also know that the next generation of Ammonites is well underway. After paying their respects to the now-deceased Ammonites, they head back to their raft and then back out to sea as the sun soon begins to rise. 
Sometime later, they find themselves back in Zealandia's coastal waters, where their voice guide tells them that all over the globe, the coast provides an ideal place for countless animals to mate, raise their young, and to feed. So, the gang head back underwater to find out, and they discover and then join large pods of Tuarangisaurus gathered together. Back in the shallow waters of Zealandia, large groups of Tuarangisaurs have come together. They propel themselves with all four fins, and travel almost effortlessly to find the fish shoals that gather here in summer. Occasionally, they break the surface to gulp air before continuing on their underwater flight. But one female is not swimming with her usual grace, and the gang realizes it. She and her two-year-old calf are lagging behind the rest of the group. So they decide to stay by her to try and figure out what's up with her. While the kids all ride with her on her back, Snoopy and Fifi ride on her calf's back. She's moving rather laboriously, and that has not gone unnoticed. 
A deadly hunter, Kaikaifilu. A Mosasaur about the size of a Killer Whale. The apparently-stricken female is a tempting target, if not her healthy two-year-old calf. They all then realize the small mosasaur that is starting to close in on them. Diving to deeper water might make her less vulnerable. She, along with the kids, attempts to escape to deeper water, while her calf, along with Snoopy and Fifi, charges at the mosasaur to harass and distract it. For the calf, trying to distract the mosasaur is a dangerous game. But it's buying time. However, the mother and calf are not entirely alone. Just when the calf, Snoopy and Fifi got the mosasaur's full attention, enraging it enough to really commit to pursuing the two beagles and the juvenile plesiosaur, at least 4 - 5 members of the Tuarangisaurus pod circle back and assist them in assaulting the mosasaur, snapping and pecking at it and forcing it to retreat. These individuals may be related, and it's in all their interests to drive Kaikaifilu away. 
With the hunter gone, the calf returns to its mother, and Snoopy and Fifi reunite with Charlie Brown and Heather. They all soon find out what's going on with the calf's mother. This is the reason for the female's apparent distress; she's pregnant. Snoopy and Fifi help her with Fifi holding her tail by the underside for support, and Snoopy trying to help pull the newborn calf out. Soon, with one last big mighty tug from Snoopy, The newborn calf emerges from its mother still curled up, how it was, and then gently unfolds. And now, after a one-and-a-half year pregnancy, a baby. A tiny sister. Over ten feet long, nearly half the length of its mother, one of the biggest babies of all time. She is immediately adorned and hugged by the Peanuts girls, even Lucy, as it is too much for her to handle this time. It needs to get to the surface to take its very first breath. So, the mother Tuarangisaurus and her two-year-old calf guide the baby to the surface, along with the Peanuts, where they all can take in a breath of air. With this, the newborn calf swims alongside her mother and older brother, who rejoin the rest of the pod as they swim around, continuing to catch fish by the cliffs of a tall, rocky landmass, the last bits of Zealandia still jutting out of the sea. The newborn calf even nuzzles Snoopy and Fifi to thank them for helping out with her birth, and they hug her in return. The Peanuts' voice guide tells them that this young Tuarangisaur could live for 80 years. Now, supported by her family, she can take her place as a predator in one of the richest habitats on Earth, the seas around the coasts of our Prehistoric Planet. 
=== Deserts: ===
Sometime later, Charlie Brown and his friends, back in their normal outfits, are in a barren, desertous region in the west of South America, and one of the most desolate places on this prehistoric planet. When Freida asks what kind of dinosaurs live here, their voice guide says that few animals venture here, yet it is the stage for one of the most extraordinary gatherings on Earth. Which, of course, is hosted by one of the largest long-necked dinosaurs that has ever existed on Earth. And they soon get the answer to all that when they then notice a herd of 17 giant sauropods heading their way, walking through the sizzling and shimmering heat of the desert wilderness. And it was a species of sauropod dinosaur they all knew whose name literally means, "Fears Nothing". Dreadnoughtus. Titanosaurs. 85 feet long and weighing 40 tons. The gang then climb up onto one Dreadnoughtus, the biggest one at the front of the herd, and hitch a ride on its neck and back.
When the kids wonder what they're doing here, since sauropods like them are usually found in rich forests and open pains, their voice guide tells them that these are all males, and they're many miles from their rich forest feeding grounds. And that they come here for only one reason: To fight for the chance to mate. Crowds of dozens or even hundreds of females scrutinize the newly arriving males, assessing their strength and suitability. Some of the males are seen bellowing, hissing and arguing with each other. They then begin showing off the bizarre gular air sacs on their necks, something the gang is amazed by, as their voice guide then tells them that the titanosaurs' immense necks are supported by an ultra lightweight air-filled skeleton and that their hollow neck bones are connected to a series of bellows that inflate those bizarre gular air sacs. Those males with the most impressive displays will attract the most females. One of the males, the one the gang is riding on; the oldest and biggest of the 17 young males, appears to be successful in attracting the attention of many females with his display. But this, however, angers an old male, who is the dominant center of attention and gets up to confront the new arrival. This huge bull, white with dust, has held the center stage for two weeks. He weighs nearly 50 tons. And his display has, so far, intimidated all challengers. He then starts inflating his air sacs to show that he is the boss. But this new arrival... is not deterred. Instead, he continues to glare right into the eyes of his opponent, showing him that he is willing to challenge him to an inevitable duel. With that, the two males circle each other, knowing that there is only one way for dominance to be established. The kids, Snoopy and Fifi knew immediately what it was, and knew that, since it was too late to get off their friend in time, they had to hold on tight to him as much as they could.
The two males rear up, and then, like modern Elephant Seals, they body slam into each other, clashing necks, like modern Giraffes, almost knocking Snoopy, Fifi, Woodstock and his pals, Charlie Brown, Heather, Linus and Janice off the younger male's neck, and then began to wrestle each other. They repeat this several times, circling each other and staring each other down before rearing up and colliding. In one clash, the dominant male pushes his rival back. The new arrival responds by resorting to more primal tactics, biting down on the nape of the dominant male to grab him and break contact. Lifting up such a huge body is exhausting. It's a battle of endurance. As the conflict intensifies, each fighter tries to wound the other, stabbing with dagger-like spikes on each thumb, and raking the skin with their teeth. Eventually, it is the dominant male that seems to be getting pushed back, and, as his younger rival repeatedly stabs at him with his thumb claws, or spikes, and bites at his neck, raking his skin off with his pencil-shaped teeth, the old bull appears to grow weaker. Until eventually... with one final neck swing from the young bull to the old bull ...the knockout blow. The Peanuts are shocked and surprised to see that their male has won the duel. The females bellow out, either in surprise or to congratulate the new champion. The older male tries to stand back up, but the impact of his 50-ton body hitting the ground proved too much, and he collapses, unable to fight anymore. The old bull's rule, after two weeks time, is finally over. The young victor takes his turn on the center stage, along with his little back-riding friends. The price of defeat, for some, is very high. As hours pass and the day goes on, as the number of Dreadnoughtus males and females in the area slowly start to leave, along with the Peanuts gang, only the, possibly-deceased, old male is left, lying in the vast desert.
Eventually, the group ends up in the deserts of Asia, where they learn from their voice guide that even though some animals are well-adapted to desert conditions, their survival is often on a knife edge, especially here in Asia, where, in the height of summer, temperatures soar above 60 degrees Celsius, and water evaporates in an instant. When Sally wonders and asks what kind of dinosaurs live here, their voice guide says that there are ferocious-looking reptiles here too. But this little lizard, that the gang meets, is only a few inches long. The little lizard runs around to find a meal, pursuing a fly across the rocky wilderness. The kids and their dogs and birds follow it in hopes of it leading them to any dinosaurs. Here, getting a meal is never easy. They and the lizard eventually comes across huge corpse with azhdarchid pterosaurs circling around it from overhead. This immense carcass could be promising. A dead sauropod, a potential feast for many. But strangely, all is quiet.
Then, a snore from a sleeping giant was heard and the gang looked around. Nearby was a group of five large predatory dinosaurs, who were resting, and the Peanuts knew exactly who they were, as this dinosaur was a close cousin to the more famous dinosaur they've met before. Tarbosaurus. The equivalent in this desert of T-rex. They know that the gang are present in the area, but having already eaten, and not seeing them as much of a meal, or even snacks, anyway, they don't mind them being around and even allow them to get as close as they want towards them, on the condition that they don't disturb them. They keep everyone else away. But for the lizard, they might bring an opportunity. If there is one thing that attracts flies more than a carcass, it's a sleeping Tarbosaur that has been feeding on that carcass. Seeing the number of flies attracted to the carcass and the smelly faces of the tyrannosaurs that fed on the carcass, the lizard, along with some others, sees the good feeding opportunity, and they all muster up some courage to go after some flies, with one running on, and another around, a Tarbosaurus, and the main one trying to catch some of the flies that gathered around its face, taking caution not to awaken the large theropod. Time to be bold. But the lizards aren't the only hunters on the prowl, as the Peanuts were about to find out.
Close by, a foot quietly takes a step as it carries a famous sickle-shaped claw on its big toe. And the head of the animal that owns the foot lowers as it reveals itself as to be another one of the most famous and legendary predatory dinosaurs. A Velociraptor. Just then, it rushes in and snaps up one of the other lizards and the gang immediately noticed it. The raptor then gently rubs its body against Charlie Brown's and purrs as it quietly stalks for more lizards while smartly trying not to disturb any of the sleeping Tarbosaurus. Time to be careful, because Velociraptors usually hunt... together, in packs. Then, a second Velociraptor, eyeing another one of the remaining lizards in the are, appears and rushes at the little creature, but the lizard manages to run away in time. The gang watches as the Velociraptor carefully sneaks around the sleeping Tarbosaurus, while seeking out more lizards to eat. Finding another one, it goes after it, the lizard rushes under a sleeping Tarbosaurus, causing the Velociraptor to bump into it, thus, waking it up. The gang then watched as the Tarbosaurus lifts its head up and roars out as it snaps its jaws at the Velociraptor, which quickly turns and rushes off as the Tarbosaurus gets up and onto its feet, causing the other Tarbosaurus to also wake up. And the two Velociraptors chittered and screeched before they retreated. The Tarbosaurs move on, in search of another meal. The main little lizard, who had survived the entire ordeal, and the Peanuts gang watch as the pack of Tarbosaurus heads off. And now the pterosaurs can come down and claim a share of the carcass. Or whatever's left of it. Nearby, the Peanuts and the lizard watch the pack of Tarbosaurus finally head off, and the lizard then skitters off after the Peanuts say goodbye to him. For the little lizard, the opportunity has gone.
About half an hour later, at sunset, as the gang search for a place to set up camp, they wonder now dinosaurs can survive in such inhospitable places with extreme conditions. Their voice guide tells them that making the most of fleeting chances is key to surviving in the desert, and some dinosaurs manage to do so very effectively indeed. For one example of which, they soon come upon a female Mononykus traveling through the desert, looking for a meal. She walks up to them and Charlie Brown gently scratches her head. Their voice guide then tells them that Mononykus is a desert specialist. And that, like many desert animals, she must patrol a huge area if she is to find enough food. Heather states that bare legs help keep her body cool. Janice states that feathers on her body shield her from the sun's rays, and that they also provide her with a super-sense. Marcie notes that they form facial discs, which look just like those of Barn Owls, that help her detect the faintest of sounds. Such hypersensitive directional hearing gives her a mental map of this hollow log, that they follow her to, and what lies within. The gang then watches as she now uses the weapon that gives this hunter its name. Mononykus, "Single Giant Claw". Just what she needs to open a termite's nest. And they also watch as she has another special piece of equipment. A flexible tongue twice the length of her head. She sticks her long tongue through the wood and licks up some termites, though some do crawl on her face in the process, prompting her to shake and scratch off the irritating insects on the log and with her feet. An excellent protein-packed meal, if only termites weren't quite so irritating.
Specialists like Mononykus can thrive in this arid desert. Then, thunder rumbles as the Mononykus warbles and heads off, with the gang right behind her. But such conditions don't always stay the same. On rare occasions, cooler mountain winds sweep in, and mix with the rising hot air. A desert storm, bringing with it welcome rain. Mononykus ran for shelter, taking refuge in a small cave in the rocks, while the gang sets their camp site up close by, and cover up their tents to keep dry. She may never before have seen the land soaked like this. It transforms this landscape in unexpected ways. Seeds that have been lying dormant burst into life. They transform this arid landscape in a matter of days. And with the vegetation comes an abundance of food, if you know how to catch it. When the rains subsided, Mononykus rushed out, curiously looking for food through the vegetation with her larger friends, checking out the trees, and a scorpion, which frightens the gang. They soon come across a flock of Cretaceous birds. Enantiornithines, an ancient type of bird. But perhaps a little too big to tackle. Running around some more, they soon near a rock with a beetle on it. It can be hard adapting to such a different and unfamiliar world. A deep sound distract the Mononykus and gets the kids' attention, and the beetle crawls off the rock as the Mononykus soon found out that it was gone. Oh, dear. Running around some more, she eventually manages to find and grab an insect. Finally, she's got something. The gang then say goodbye to her before she rushes off, presumably to find more food. But these new challenges will be brief. One thing is certain in the desert: Searing heat and scorched earth will soon return. Flowers will be nothing more than a distant memory. 
Elsewhere in the vast Asian deserts, the Penauts gang cross over huge sand dunes with wind blowing over them, where their voice guide tells them that it's not just the unrelenting power of the sun that makes deserts so inhospitable. So, too, do winds. The kids and their dogs and birds then find themselves on a flat section of desert, where their voice guide also tells them that, here in central Asia, the winds rip across the landscape, drying out the land still further and uprooting vegetation. While witnessing a sand funnel go by, they notice a herd of large migrating hadrosaurs on the move. Their voice guide, in narrator form, tells them that large dinosaurs keep on the move to try to cope with these harsh conditions, and that these duck-billed dinosaurs are Barsboldia. The gang decide to stick with the herd in hopes of finding water, since they could some right about now since they're starting to run low. Charlie Brown, Heather, Linus and Janice, along with Snoopy, Fifi and Woodstock and his pals, climb up onto one Barsboldia, while Sally, Marcie and Peppermint Patty climb up onto another. Then, Lucy, Violet, Patty and Frieda climb aboard another Barsboldia, while Schroeder, Franklin, Shermy and Pig-Pen hop on another one. Charlie Brown says that they all know a lot about hadrosaurs, but not so much about this one in particular. Their voice guide tells them that they are long-distance specialists and can go without water for an astonishing length of time. But on rare occasions, there is an abundance.
After trekking for quite a while, the gang and their travel companions then notice something astonishing up ahead which they eventually arrive at; an oasis, with dozens, if not hundreds, of dinosaurs gathered around it to drink water, like Barsboldia, Mononykus, Tarchia, Therizinosaurus and Nemegtosaurus, along with Azhdarchid Pterosaurs, as bellows fill the air. When rain does fall, it can seep into the land and travel great distances underground. Until, in some special places, the water rises to the surface and creates an oasis, like this one. The kids then use a water purifier they're brought to help them replenish their water supply for the rest of their adventure that lies ahead. Open water attracts desert animals of every kind from many miles away. Some dwarf everyone else. Nearby, approaching the oasis, a herd of desert giants is also on the move as they made their way towards the watering hole. They are a herd of Titanosaurs. The Peanuts are astounded by them, as they've never even heard of these dinosaurs before. Their voice guide, as the narrator, identifies them as the Mongolian Titan. They are colossal. Weighing over 70 tons, they are among the biggest animals to have ever walked the Earth. A risky place for a tiny Mononykus to come for a drink, as one of which ran and weaved between one's legs. The Mongolian Titan herd approaches the watering hole as one nears the shoreline of the water and a few Barsboldia moved aside. And the Peanuts gang managed to get through the crowd to get a better look of the giants. There may be a crowd, but if you've got the longest neck on Earth, you can jump the queue. With their great sizes and long necks, the massive titanosaurs were able to drink water from the oasis and skip the animals around and in front of them, eliciting some curious stares from some of those who are closest to the gigantic sauropods.
All around the oasis, dozens of dinosaurs drink from the watering hole, from the tiny Mononykus to the giant Mongolian Titan. And even the Peanuts gang got a share of water. However, as even they know, such a gathering attracts attention. And in the distance behind them, a shape emerges from the ridges of the dunes. A Tarbosaur. A lone Tarbosaurus stood on top of the dune and stares at the oasis bellow, before eventually descending down the dune as some of the Barsboldia then noticed him. And it wasn't too long before the Peanuts gang saw the Tarbosaurus as well. They know that gathering like this always attract the attentions of predators, as well as prey. The Tarbosaurus continued his way towards the watering hole as the gang and the Barsboldia watch him. Soon, the herd started to moved aside as the Tarbosaurus approaches the watering hole, and he turns to both sides of the herd as he nears the shore of the water, and the herd lows and grunts as the kids, Snoopy, Fifi and Woodstock and his pals all watch him in amazment, astounded by his majesty. The Tarbosaurus then notices them, and gives them all a curious stare before turning his attention back to the watering hole, and then, stood in his place for a few moments. The Peanuts gang were unsure of what would happen next, although the Tarbosaurus showed no signs of hunting behavior, and didn't look interested for a meal. But, like everyone else, the hunter is here just for water. The gang watch as the Tarbosaurus drinks his fill. With so many thirsty mouths drinking day and night, the water doesn't last long. The animals, and Peanuts gang, disperse, and once again, the harsh, arid conditions return.
The gang then find themselves back in North Africa, trekking alongside huge desert canyons. Their voice guide tells them that over millions of years, water has carved some deserts into spectacular landscapes. As here in North Africa. These canyon lands offer some desert visitors special opportunities. When the gang asks what kind as they reach a cliff ledge, they use their binoculars to look out over the North African desert and then spot a particular species of pterosaur that they have seen before. With a 17-foot wingspan, Barbaridactylus, a type of pterosaur, can exploit the thermals with effortless skill, and so, cover great distances, despite the fact that some have enormous head crests. The gang then hitch a ride on some of the Barbaridactylus as they carried them and flew to a high rise of rock with a flat plateau where several others were gathered. Every year, males and females gather at these special places in the sky, in their thousands. There are no ground predators on the summits of these isolated plateaus, so they're safe places on which to land, allowing them to rest and attract mates. Once they were all safely on top of the plateau, the Peanuts then watched as the Barbaridactylus began their ritual courtship displays. Large males select an area in which to perform their displays, whilst eager young bachelors circle overhead. The gang then watched as a male Barbaridactylus lands on the plateau, hoping for a chance. Territory holders warn off any challengers, a message that sometimes needs to be violently reinforced. One male, deciding to prove his dominance by more physical means, attacks his rival, biting his foot as he tries to fly off, and chases him around the plateau. He attempts to destabilize the other male by grabbing his foot as they fly, momentarily disorienting him. After a bit of time, the dominant male finally knocks his rival against the mesa's wall, causing the challenger to lose his balance, strike the wall for a second time, and fatally plummet to the rocky slopes below, where his body is buried by sand and rocks, at which, the kids, two beagles and birds all winced and cringed at.
But you don't necessarily have to be heavyweight to succeed. The gang's voice guide tells them that there are some males that don't develop the huge head crest. One of them, along with a few more, lands on the plateau and carefully sneaks into the colony undetected. The gang's voice guide then tells them that they are sneaky males that look like females, and so can try to remain unnoticed. The kids and their dogs and birds are surprised by this and then join one of them. He attempts to woo a female with his courtship song and mating dance, though he is clearly trying to keep a low profile and not give away the fact that he is a male. It's a dangerous game to play, because the large males are regularly on patrol, and they perform their displays. One of them attempts to court a female himself, by showing off his head crest and holding out his wings. But the female, it seems, doesn't seem to be all that impressed or interested in him, so, she turns and walks away, rejecting the male's advances. This causes Schroeder and Linus to give Lucy and Sally each a smugly look to show them each that, just like girls, boys don't always have it their way either. With that, the large male looks through the many other females around him, and notices something in particular. One of the sneaks has been spotted. And the gang notice the large male, who begins to approach the sneak, as looks around, trying to decide which female to court next, and then also notices the large male as he gets up right in front of him, surprising him. He anxiously looks up the large male as he looks back down on him, hoping his cover isn't blown. The Peanuts watched as neither pterosaur broke eye contact as the were both in a stare down. But in fact... he caught the eye of the large male. So, surprisingly, however, the large male, fooled into believing that the sneak is another female, begins doing his ritual courtship song and dance, spreading his wings to show off his size, surprising the gang, in a baffled sort of way. But, after collecting the experience he needs, then, the sneak pretends to be a reluctant female... and rejects the male's advances. With his advances rejected yet again, the large male simply walks away to woo another female, none the wiser that he has actually faced another male.
The kids and their dogs and birds follow the sneak as he approaches a female. Now, back to the mission in hand, and time to make his move. He then performs his mating display before her with a head-bob and side-to-side motion. For a few moments, they stare at each other, as the female looks at him, deciding if he is worthy, while the male stares back in anticipation. Finally, at last, the female reciprocates the male's song and dance. Success! The gang is relieved that the courtship was successful, and Snoopy holds and hugs Fifi as she swoons from it. Heather and Janice then note that modern animals use this type of sexual mimicry too, with Charlie Brown, Linus and Marcie in agreement. The gang then watches as the male and female Barbaridactylus then gently gnaw each other's beaks and soon the male moves around behind the female to mate with her, holding her by the back of her neck with his beak to make sure she doesn't fall over as the mating process begins. Large males might seem more attractive, but the females, it seems, ensure producing the fittest young by mating with as many partners as they can, whether they're impressively adorned, or just sneaky.
Sometime after that, the group ends up back in South America, where their voice guide tells them that it's not just extraordinary bizarre animals that live in the deserts of the Prehistoric Planet. There are strange, otherworldly landscapes too, such as here in South America. When the gang ask what kind of desert it is that they're in now, since it's not like any other kind they've seen before, their voice guide then tells them that this may look like a dusting of snow, but these great dunes are composed, not of sand, but of gypsum. Marcie explains that gypsum is a fine, white mineral that dissolves in water so easily, it can only exist in solid form in the driest areas on Earth. These dunes are so dry that living here is almost impossible, yet some dinosaurs manage to do so. And when Franklin and Shermy ask what kind for instance, they get their answer when they all come upon a herd of mid-sized dinosaurs wandering around within a rocky area with long-dead trees. Secernosaurus, a type of small hadrosaur. As she strokes a one's snout, Sally says that she never knew or even thought of hadrosaurs that lived in South America. Marcie tells her that they are one of the only hadrosaurs that live in South America, and they're very unique to which as as well. Janice also states that one of their closest relatives is another hadrosaur called Gryposaurus. The gang's voice guide, as the narrator, tells them that although they can survive on a poor-quality diet, every decade or so, this area dries out so extremely, that almost all the vegetation shrivels and dies. One individual feeds on the few remaining dried-out shrubs it can find before attempting to chew off one of the low-hanging branches of a shriveled-up tree. However, it is clear that there is nothing left for the herd to subsist on, with the only reminder of sustenance being the shimmering mirage of an oasis flanked by vegetation. With young to care for, this could be the end of the herd. But some of the older, more experienced individuals may remember other potential sources of food and water, and they know that the way to survive is not to try to leave the desert, but to continue traveling across its baking dunes. So, determined to survive rather than simply waste away in the middle of the desert, the herd decides to set out and find true food and water.
With high winds and shifting sands, the desert is always on the move. And that makes navigation tricky. The herd prefers to travel at night. So, the kids split into four groups, one consisting of Charlie Brown, Heather, Linus and Janice, along with Snoopy, Fifi and Woodstock and his pals, one consisting of Sally, Marcie and Peppermint Patty, one consisting of Lucy, Violet, Patty and Frieda, and one consisting of Schroeder, Franklin, Shermy and Pig-Pen, and all each hop onto a Secernosaurus, as they begin their desert night migration. It's not only cooler, but also reveals a map that could enable an animal to find its way through the featureless yet ever-changing desert. A map in the sky. As they travel in the darkness and coolness of the night, they navigate the desert by relying on the stars overhead that from a mental map of celestial signposts and constellations. Marcie notes that, like many migrating animals, hadrosaurs can recognize celestial signposts. By day, the blistering sun still beats down from overhead. After what may be one or several days, the herd and their travel companions are next seen resting in the shade behind a dune, taking refuge from the heat of the sun. Even if they can find shade, this, for some, can be journey's end. But there is something else that may help them. The deep, rumbling sound of waves crashing onto the distant shoreline travels for miles through the dunes, which the gang needs to listen very carefully to, in order to hear it. The sound is so low that many animals cannot hear it, but hadrosaurs can, and so are able to find their way towards the coast. But this desert still has one more obstacle that must be overcome. Giant, coastal dunes that block their path. The climb proves difficult. Steep, unstable sand saps energy with every step. And one juvenile calls out to its mother, exhausted, though the mother calls out to her calf and manages to convince it to continue just for a little longer, with the help of Snoopy and Fifi helping it up the dune. Finally, at last, the herd and the Peanuts gang manage to reach the top of the coastal dune. They have made it, and their first award is to lick droplets of water that condense on their skin from the fog that forms where dunes and ocean meet. And this fog also nourishes a rich, coastal paradise. At last, the herd, along with their travel companions, has found a sufficient amount of food that can keep them and their young alive and well-fed for the time being, sustenance that, until the day it runs out, will bring them relief from the inhospitable gypsum deserts of Argentina. The Peanuts' voice guide tells them that this is enough to feed the herd for now, but once it runs out, they will be forced to move on, and once more endure the trials of life in the deserts of the Prehistoric Planet.
=== Freshwater: ===
Sometime eventually, Charlie Brown and the gang return to Asia, where, right now, they are hiking alongside a canyon carved up by a river. Their voice guide tells them that, for millions of years, the lands of Planet Earth have been carved by water. And the rivers that flow here are still shaping these great canyons. Linus states the fact that the Grand Canyon, back in Present-Day times, is split and carved by a freshwater river. Such places are the home of flying reptiles. Pterosaurs. The gang notice a small flock of little ones flying overhead, heading in the same direction that they are. Their wings of skin stretch from finger to ankle. And they can fly for hundreds of miles in a day. The gang follow them along the river, all the way to a waterfall by some steep cliffs. All around them were other pterosaurs, and many of them were roosting on the narrow ledges of the massive cliffsides by the waterfall. Woodstock and his pals are amazed by how many of them there are and decide to fly around with them for a little while as the rest of the gang looks on. Their voice guide tells them that each evening, they come to this canyon in huge numbers to roost on its narrow ledges. There is safety in numbers. And anyway, few land-living hunters venture here. But one does.
When the kids wonder what kind it is, they soon get their answer when it shows up as a pair of feet that carry familiar-looking sickle-shaped claws on the big toes land on a rock near where they are at the base of the waterfall. A type of dinosaur. Velociraptor. The most famous of all the dromaeosaurids. And one of the most well-known and legendary dinosaurs. A trio-pack of Velociraptors arrive, consisting of two males and a female, and the gang instantly notices them. They each then gently rub their bodies against each of the kids' and purr, and even nuzzle both Snoopy and Fifi, before they near the waterfall base at the cliff. The kids' voice guide tells them that their bodies are kept warm by feathers, but they can't fly. But, they are, however, exceptionally agile and quick, just as they always have portrayed in media. And just as well. One false step here could bring disaster. Either for themselves or for the hunt itself. The pterosaurs are skittish. They would take to the air at the first sign of danger. If the Velociraptors are to get a meal, the element of surprise must be crucial.
So, wondering how they will successfully catch a pterosaur, the Peanuts gang follow the Velociraptors as they make their way down the precarious cliffside. They watched as raptors carefully hopped down on one rock after another. They learn from their voice guide that lightweight bodies and feathered arms help them to control their descent. And their broad tails assist them in keeping their balance. So the gang use their rock-climbing gear in order to keep up with them. Charlie Brown and Linus soon noticed that the pack seem to be going for the pterosaurs at the edge of the roost. And so, those pterosaurs that are resting on the margins of the colony will likely be the easiest targets. Just then, as the raptors silently begin their approach, as they leap down from a raised ledge, one of the two males' foot slips, causing some rocks to fall and crash, momentarily startling the pterosaurs from below them. The gang notice this as well. But luckily for them, the pterosaurs still haven't noticed them. The roar of the waterfall drowns the sound of slipping rocks. With the pterosaurs still unaware of their presence, the Velociraptors continue their approach, with the gang still watching and following them, are now just a few yards away from the nearest pterosaurs. Then they prepare their ambush. The female goes high, up onto a higher ledge and positions herself. The two males stay low, and assess the ambush. The Peanuts watch as they wait for the perfect moment to strike. A few pterosaurs are almost within striking distance.
Then, from above out of nowhere, the female launches her ambush attack and pounces down on a pterosaur, surprising the gang and frightening the other pterosaurs in the process, grabbing it with her jaws and dragging it across the cliffside as both of them fall down on a lower ledge. She soon gets up, unhurt by the fall, and bites down on the pterosaur's neck to make the final killing blow. The two males soon leap down and join her. She has one. But now the whole colony is alarmed. As Woodstock and his pals rejoin the gang after they've realized what's happened, Suddenly, the thousands of pterosaurs resting all over the canyon, now aware of the assault, screech and swoop in to mob the dromaeosaurs, which try to leap and fight back. Not wanting to be mobbed themselves, the kids, Snoopy and Fifi all climb back up to higher ground, and then watch from atop of the cliff what is currently going on at the moment. In the chaos, her victim slips from the ledge. Seeing this, the gang watches the female puts the effectiveness of her feathered tail to the test. She leaps off the ledge, using her agility and feathered tail to control her descent, leaping and rolling off the walls until she got to the bottom. And, in the end, she gets her meal. The males are left to face the pterosaurs. But they will rejoin her once they've finished dealing with them. The gang take one last look before eventually moving on, knowing that there is nothing they can do about it. The power of fresh water is at work all around the planet.
An hour later, and the Peanuts are now in North America, where their voice guide says that global temperatures are high and there are violent storms and torrential rains. Much of North America is covered by thick, lush forest. The kids and their dogs and birds wander through its dense undergrowth, wondering what kind of dinosaur(s) they'll see this time. Their voice guide tells them that here live some of the most gigantic plant-eaters that have ever existed. And they, in turn, are prey for the most ferocious of hunters. They soon pass by a tree with a patch of blood on its base, then come upon the huge corpse of a dead dinosaur as a fly buzzes and lands on its eye. And close by, a tree branch drips blood. Then they heard the sound of a dinosaur grunting and looked around. And soon, just a short half a meter away from them, a familiar-looking predator woke up from his nap and rose up its head and soon got to its feet and stood before them. And the gang instantly knew what kind of dinosaur it was, as it was another one of the most well-known famous and legendary dinosaurs.
Tyrannosaurus rex. This old male has just recently brought down a Triceratops in battle. But in doing so, he's been injured. The gang then notice two large gash wounds on the thigh of his right leg, and Charlie Brown theorizes that he must've gotten them from one of the Triceratops' horns during the fight. So, Snoopy and Fifi climb up onto the old male and observe his wounds to what can be done about treating them. The gang's voice guide says that T-Rex are built for hunting large herbivores. Though many of those have evolved heavy defensive weapons. And Linus states that even the world's last biggest, greatest and mightiest predatory dinosaur needs to be careful when hunting such dangerous prey, as the old male Tyrannosaurus begins to feed on his battle prize. Whilst he does so, the kids observe his body, which was covered in, more minor, healed battle scars, and could tell from his size, age, and condition that he is, indeed, a battle veteran. Decades of battling armored prey has scarred his body. One battle even cost him the tip of his tail. Linus theorizes that it must've been bitten off when he was once fighting another T-Rex. These new injuries are more serious. Once he's finished eating, the giant theropod heads off with Snoopy and Fifi riding him and the kids following him. At his great age, infection is a real risk. He leads them all to a nearby river, which makes up a huge part of the borderline of his territory, and begins to drink from it. River water could help to clean his wounds. The Peanuts then watch as he then steps into the river to treat his injuries and wash the blood from his meal off his face. He stands a good chance of living to fight another day. But that day could come sooner than expected.
The Tyrannosaurus then acts up and senses the presence of an intruder approaching his territory. And the sound of leaves rustling nearby as he turn to the forest on the other side of the river, beyond the borderlines of his territory. As he and the gang were about to find out... they're not alone. Another T-Rex. A stranger. The two theropods roar out and growl at each other and size each other up. The kids know that that could mean trouble since they know that Tyrannosaurs like T-Rex will often aggressively fight for territory... and are not above cannibalism, even though they rarely show it. But this newcomer has a different smell. And so, there's something else on the old male's mind. For he has identified the newcomer's gender. It's a female. She's younger and smaller. But nonetheless, she might also be a rival. Just then, the male T-Rex raises his head, exposing his neck and showing an orangish-reddish color on it, and makes a deep, soothing, vibrating sound with his throat. He, however, makes it clear that he's not interested in fighting. He would prefer to mate. And that means showing off his best moves to win her over. She seems to approve. And so, the gang are both surprised and amazed. The two Tyrannosaurs then lowered their heads, and the female nears the male. The facial area of a tyrannosaur is very sensitive to touch, and they nuzzle. the female then meets the kids, as well as Snoopy and Fifi, and Woodstock and his pals, before she resumes nuzzling with her new mate. Then, they head off with the gang following them. His great size and his battle scars are evidence that he is a survivor. And that, perhaps, in her eyes, makes him an attractive partner. Eventually, somewhere close to the edge of the forest, the Peanuts were watching as the old female T-Rex was laying on the ground, and the old male T-Rex begins to mount her. As the cycle of life begins again. So, they stay together, and in the coming weeks, they mate frequently. Eventually, she'll lay up to 15 eggs, and with them comes the promise of the next generation. Soon, they get up and move out together, either to hunt food together, or find a better place to rest and mate in. The Peanuts bid their two T-Rex friends farewell before eventually moving on themselves.
Habitats that depend on fresh water can change rapidly and radically. In parts of central Asia, where the gang has now returned to, once again, heavy seasonal rains fill the rivers until, eventually, they overflow their banks. The surrounding plains are flooded, turning them into floodplains. The Peanuts were in their raft as they gently paddled through the floodplain, as many water plants stood before them. And through the water wades one of the most bizarre of all dinosaurs. And that's when Patty asks what kind of dinosaurs live here and gets her answer when the gang comes upon a large dinosaur with a Spoonbill-like head, a sail-like hump on its back, a thick coat of fur-like feathers, and incredibly long arms emerging from the reeds, feeding on a mouthful of water plants. As it was, indeed, one of the weirdest and strangest dinosaurs of all time. And they were both surprised and amazed by what they were seeing.
Deinocheirus. Heather and Janice state the fact that it was once thought to be a therizinosaurid, until it was later reclassified as a giant member of the ornithomimid family. The gang's voice guide then says that it's even taller than T-Rex, but no where near any bigger. And its massive duck bill-like snout is very effective in gathering water plants. This male feeds voraciously, having eaten very little during the long dry season. The gang then follow the Deinocheirus in their raft and watch as he lowers his large arms into the water. Water plants are rich in nutrients, and his huge, curved claws, eight inches long, enable him to dredge them up from deep beneath the surface. Once he's finished doing so, he then lowers his head and scoops up and grabs a mouthful of water plants. He himself is a source of food for smaller creatures. Bloodsucking flies, which infest his coat of feathers. The kids and their dogs and birds watched as the Deinocheirus scratches himself by the neck and head, and some of the flies started to swarm them and they swatted them away as best they could, with Snoopy swatting them away with a fly swatter he packed. They're irritating, and even painful. And while his huge claws enable him to have a good scratch, there are always some spots that are just out of reach. To get to them, he needs assistance. The Deinocheirus looks around for a solution and then notices something that could be helpful. A dead tree. That could be the answer. The Peanuts also noticed the tree and know that it could be helpful to him. They paddled over to it alongside the Deinocheirus as he made his way over to the tree, and then, they climbed up the tree in time as the Deinocheirus then started scratching himself against it, and used it as a scratching post as he gave himself a good scratch. And the Peanuts gang saw the relieved look on the dinosaur's face. That's much better. The Deinocheirus continues scratching himself against the dead tree for a little bit and soon finishes. And now, he can get back to feeding.
The kids, Snoopy and Fifi climb down the tree and back into their raft. But, they've been noticed by the Deinocheirus, who turns his head to face them. He then sniffs the gang and Charlie Brown and Heather gently stroke and pat his bill to show him they're not a threat. And Woodstock and his pals fly up onto him with back scratchers and give him some additional scratching, comforting and relieving him some more, and having them and the gang earn his trust and respect. After that, he then instinctively returns to feeding. The Deinocheirus lowers his bill into the water and grumbles, and soon lifts his head up with a mouthful of plants in his bill. But a diet that consists almost entirely of wet vegetation does have one, inevitable, consequence. Just then, as the Deinocheirus grunts, a splash was heard. Underwater, a dropping sinks down. What was food for one becomes fertilizer for many others. The Deinocheirus then sways his tail from side to side. And a giant as big as Deinocheirus can produce over 20 tons of dung every year. The Peanuts gang then watch as the Deinocheirus heads off, biding farewell to him before moving on as well.
After a short while, the gang find themselves in a new environment. Southern Africa. Their voice guide tells them that, here, too, the annual rains create floods. And the land turns into a maze of narrow channels running between countless small islands, which the gang paddle through on their raft. This is now a swamp forest. And it attracts one of the largest flying animals that has ever lived on Planet Earth. The Peanuts look up at the sky, and, in the air, a giant pterosaur soars above the forest. And the kids, Snoopy and Fifi knew exactly what it was, as it was the largest flying animal ever, and the biggest species of pterosaur of all, which gives it its title, "The King of the Pterosaurs". A giant pterosaur. Quetzalcoatlus. This is a female, her wings are over 30 feet across. And she's come here for one particular reason. So, the group follow her, and wonder why and what it is that she's come all the way here to South Africa, since her kind is usually native to North America. They get their answer when she then adjusts her wings, slowing her descent and soon lands on the banks of a big enough clearing, and when their voice guide tells them that the small islands created by the rising waters are just the place for her to lay her eggs. So, it turns out the reason that she's flown all the way here is that she is to be an expected mother.
Like all pterosaurs, Quetzalcoatlus are certainly masters of flight. But they're also, perhaps surprisingly, very competent on the ground. After hauling their raft on the shoreline, guarded by Woodstock and his pals, the gang then follow the giant female pterosaur through the forest as the watch how she walks. Each wing is supported by the single greatly elongated bone of her fourth finger. By turning her wings upwards, she can walk very effectively on all fours. She's come here to make a nest. She chooses to do so on damp, swampy soil that will prevent her soft-shelled eggs from drying out. From what the gang remember from around when their adventure began, pterosaur eggs have leathery covering that can dry out easily in the sun, so they need to be kept moist and covered. As the female Quetzalcoatlus makes her nest, the group sets up camp next to of which. Once the nest is made and built, she then squats down and starts to lay her eggs, comforted by Snoopy and Fifi, who help her through her egg-laying proccess. These first two are just the start. For the next three weeks, she will guard the open nest, and add two more eggs every few days. A timelapse is shown of the mother azhdarchid, along with her smaller friends, walking around her nest, patrolling the area, sleeping alongside her eggs, and standing for long periods of time above her nest to add another pair of melon-sized eggs to the clutch. Producing eggs takes a lot of effort and energy. Each one is huge, weighing around a kilo. Eventually, she produces a clutch of a dozen or so. She covers them with vegetation to conceal them. Now, she needs to eat. So, she leaves the gang in charge of keeping an eye on her nest while she's off hunting. There should be enough food on this island to sustain her youngsters when they hatch. But there's nothing substantial enough here to satisfy her own hunger. She must leave to hunt for prey elsewhere... and trust that isolation of her nest, and the Peanuts gang, will keep her unhatched young safe while she's away.
The kids, Snoopy and Fifi stood by and watched over the nest as they waited for the mother Quetzalcoatlus to come back. But as they know, it's never a good idea to leave a nest unattended for too long. They then heard some leaves rustling as a bird flies off cawing, and the shape of familiar-looking creature as it made its way through the forest. Another, much older Quetzalcoatlus female. She too is looking for a safe place to lay her eggs. And there may not be enough food here for two sets of giant nestlings. But there is a way to solve that problem. And the gang knew immediately that this meant trouble, as she stands over them and the younger female's nest. Despite their many attempts to fend her off, she single-handedly bullies them off the nest, even Lucy, and then starts removing the leaves and vegetation and soon uncovers the clutch and lifts her head up with an egg in her beak. And soon crushes it, killing the developing embryo inside. And, eggs, after all, are very nutritious. The Peanuts then watch in horror, with Heather, Janice and Fifi comforted by Charlie Brown, Linus and Snoopy, as the older female stomps on the nest and tears more of it open and tosses another egg, and then she grabs another egg and swallows it whole. She continues to make more of a mess of the nest, until, suddenly, she then looks around and senses the fact that she's not alone.
The owner of the nest is back. The younger female groans out returning from her hunt, and by the looks of it, she is definitely not happy at all. The kids, Snoopy and Fifi are all so relieved that their friend is back, as she fearlessly puts herself between them and her nest, and the intruder. They soon confront each other and the younger female attempts to drive off her rival by raising herself on her hind legs and spreading out her wings while squawking and bellowing repeatedly. Undeterred, the older female angrily snaps at her. And then, they went on the offensive as they start jabbing their beaks at each other and attempt to stab and grab each other, grappling the adversary before them with their long beaks several times. The Peanuts gang watch as the younger female looks to be gaining the upper hand as they both hissed and grunted. And then, unable to take much more, eventually, the older female is forced to retreat. The younger female aggressively bellows and squawks out loudly at her rival as she flies off to find another, more safer, place to lay her eggs.
The older female is driven off. But the younger female's nest is already wrecked. The kids, Snoopy and Fifi comfort her as she stares distraughtly at her almost-totally-destroyed hard work. Out of the dozen eggs that she laid, only three have survived. Which means her clutch is now reduced to three eggs. The loss is a setback, but, at least it's not that much of a disaster for the mom to be. The success of her breeding season now rests on these three fragile eggs. She will protect them as best as she can until they hatch in a few months' time. But after that, her young will have to fend for themselves.
Sometime after saying goodbye to their Quetzalcoatlus friend, the group ends up on a flat section of inland river beach in Madagascar. As river water flows downstream, it scours out billions of tons of sand and gravel and even shifts great boulders. The finer sediments may be transported for hundreds of miles, but as the river broadens, it slows. And as a consequence, it begins to drop some of its load. And animals whose ancestors lived in the sea begin to appear. Crabs. In some places, there may be dozens per square meter. The gang then watches as, suddenly, some of the crabs were snatched up and eaten by something, and the culprit turns out to be a small predatory dinosaur about the size of a family dog and with the strangest set of teeth at the front of its jaws. 
This is Masiakasaurus. A female, six feet long, and she has a mouthful of needle-sharp teeth, just what you need to deal with awkward, multi-legged prey. Peppermint Patty states the fact that Masiakasaurus' front teeth project and forward, making them look essentially like buck teeth. The female Masiakasaurus then sniffs the kids, Snoopy and Fifi, as well as Woodstock and his pals, and knows immediately that they're not a threat. So, she continues to hunt crabs. The kids' voice guide says to them that Crabs may have hard shells, but they're full of protein. Too good an opportunity to miss. And not only for her. Just then, the gang noticed three younger and smaller Masiakasaurus emerging from behind a log, chittering. She has three young. Only four inches tall. And not quite ready to take on large crabs. The three baby Masiakasaurus then run over to their mother, and she drops a dying crab in front of them for them to eat. They still rely on their mother's leftovers. 
When Violet wonders how old they are, Linus and Janice estimate that the infants are probably only a few weeks old, even tough they've already left the nest. But some youngsters develop hunting instincts early. As the youngsters feed on the crab, one of them turns its attention elsewhere. Very tempting. The Peanuts gang watch as it eyes a small crab that can be swallowed whole and stalks it. But just as it ran at the crustacean, it had already retreated into a burrow under a piece of driftwood. The smallest crabs can be swallowed whole. Unfortunately, what they lack in size, they make up for in speed. They then watch As the juvenile continues running across the shoal and poking through the ground, trying to catch crabs by itself, but with little success. Just then, its mother squawks out for it to either come back or be careful. It's best for the young not to stray too far. The juvenile, upon finding another crab to hunt, runs towards its prey, nearing a pool of water. Suddenly, a large amphibian lunges out and grabs the youngster with its tongue, pulling it, shrieking helplessly, into its mouth in under a second. The other youngsters watched in surprise, along with the Peanuts gang, as their sibling was swallowed whole by the giant frog, and the kids knew immediately what it was. 
Beelzebufo, the "Devil Frog" or "Devil Toad". One of the largest frogs that has ever existed. The mother Masiakasaurus stares at the giant frog in disbelief as her two remaining youngster ran over to her and hid behind her. With his hunger satisfied, the gang watches as the Beelzebufo lowers and sinks back down into his pool. He won't need to feed again for a month. With nothing more that can be done about what just happened, the mother Masiakasaurus leaves the sandbars with her two surviving offspring, as the gang say goodbye to them. These sandbars may be a rich feeding ground, but there can be a high price to pay for living here.
Sometime later, the gang ends up in the lush river forests of South America. The river water is now approaching the sea. A taste of salt in its waters is already detectable. At the forest floor, on a mangrove river, the gang paddle peacefully down it in their raft as the forest's wildlife fill the forest chorus. At high tide, visitors come in from the open sea to explore these channels. Just then, the kids, Snoopy, Fifi and Woodstock and his pals all realized that they weren't alone as a creature of some sort swims through the river alongside them and their raft and it rose up as its back breaks the surface, and it wasn't alone either as others were with it. And on the bank of the river, a Quetzalcoatlus curiously watches them all pass by. Underwater, swimming through the murky water, were the creatures. Elasmosaurs. When the gang wonders why they're here, their voice guide tells them that these are true ocean-going reptiles. But some come to estuaries to explore the brackish waters. And so, the Elasmosaurs continue on to where the river widens, with the gang by their sides, and soon arrive at an open area of it where the kids and their dogs and birds can get a better look at them. That there is where more inhabitants of the forest (namely a few small pterosaurs and a giant South American sauropod, which isn't Dreadnoughtus) also take an interest in the peculiar presence of the normally ocean-dwelling creatures as well.
The Elasmosaurs and Peanuts gang continue downriver and eventually end up at a bay where the murky waters of the river meet and mingle with the sea. Now, the millions of tons of sediment carried here by rivers is finally delivered into the sea. The river water takes time to mix with the ocean, and, for a while, the two waters flow side by side. The gang's raft soon floats over a section where the brackish and ocean water meet as sediment is seen at the surface. Nonetheless, great shoals of fish find plenty on which to feed in these waters. Below them, shoals of fish swim through the sediment clouds and suddenly change their directions. The clouds of sediment conceal the fish if they're any distance away. At the surface, the Peanuts can see the shapes of the Elasmosaurs swimming below. But the Elasmosaurs don't hesitate to swim into the murkiest of water to pursue their prey. There, they pursue the great schools of fish, circling around them as they panic to agitate and pin them right where they want them to, leaping out of the water to catch mouthfuls of fish as they try to jump and escape. There is no escape for the fish, even above the water. The elasmosaurs are seen diving in and out of the clouded boundary between river and ocean, catching as many fish as they can. All the kids agree that it is a marvelous and spectacular sight to behold. These elasmosaurs collect the last of the river's gifts before its traces are finally lost in the oceans of the Prehistoric Planet.
=== Ice Worlds: ===
Sometime after that, the gang return to North America, and are up in the far north of which, in the snowy forests of Alaska, where, at first, all is quiet, with the exception of the night chorus filling the air. They are all now wearing their winter outfits to keep warm and are looking for any signs of dinosaurs, while wondering what any species of which could live here. For one example of which, they find a set of footprints that are seen in the snow, leading to the one who left them, and follow them. Their voice guide says to them that life is at its harshest in the far north and south of Planet Earth. Dinosaurs, however, have managed to colonize these polar regions. In the early hours of the first morning of spring, they notice and watch a sleeping dinosaur, a Dromaeosaurus, a type of raptor, all curled up, as it then wakes up, gets to its feet and scratches itself. In the far north of America, this tiny hunter, a dromaeosaur, has managed to survive three months of near-total darkness. And now, at last, spring has come. The Dromaeosaurus then sniffs each of the kids and gently rubs her body against Charlie Brown's and purrs, and then nuzzles Snoopy and Fifi, before heading off, running through the forest and across the snow-covered plains, and the Peanuts gang follow her, even though she's much faster than they are, digging through the snow and the rocky ground in hopes of getting a meal where she has found food before. She has a coat of feathers, for she's able to generate heat in her body and needs to retain all she can. A challenge for all dinosaurs in these cold latitudes. As the gang watched as the Dromaeosaurus was on the hunt, she soon heads off and they follow her, and she stops for a moment and scans the area for prey. As she moves quickly over the surface of the snow, she checks on the places where she has found food in the past. She soon spots a beetle, climbing up a branch. In this icy world, no opportunity is too small to be ignored. The Peanuts watch as the Dromaeosaurus growled as she eyes the beetle, totally focused on it and slowly creeps toward it as the beetle brought it's wings out and started flipping them in preparation for takeoff. And to succeed, as usual, you need... The beetle soon flies off the branch, ...good... and then, the Dromaeosaurus uses her quick reflexes and leaps up in the air and snags the beetle with a crunch. ...timing. The kids, Snoopy, Fifi and Woodstock and his pals were amazed by this. The Dromaeosaurus then chomps down on the beetle and soon tosses it into her throat and swallows it, getting the first meal she's had in a long while. She then approaches the gang and nuzzles Charlie Brown and Snoopy.
And soon, sunlight started to shine, as the sun finally began to rise over the mountains of Alaska. Although at this time in Earth's history, the polar regions are relatively warm, these lands are, nonetheless, ruled by extreme seasonal change. When the sun rises for the first time in almost three months, every animal must be ready to make the most of the daylight and the warmer days that are to come. The Peanuts watch as a pair of two Dromaeosaurus approach and confront each other as one held its arms out, and they soon nuzzle each other before turning their attention to them and staring curiously at them for a bit. The little dromaeosaurs must work together as a pack if they are to take on big prey. They and the Peanuts gang soon turn their attention to the bellows of a nearby herd of dinosaurs in the distance that fill the air. And here comes their first chance of the season. A herd of Hadrosaurs. Charlie Brown instinctively notes that they are called Edmontosaurus, North America's biggest hadrosaur. The kids, Snoopy, Fifi and Woodstock and his pals are intrigued by this herd of giant plant-eaters, and even hitch a ride on some of their backs. Their voice guide tells them that these duck-billed dinosaurs pass through here every year. Nomads in search of the fresh vegetation brought by the spring. Heather and Janice state the fact that these dinosaurs are true migraters, traveling long distances to escape the Arctic winter, and journeying back north again when it's warmer again. And Charlie Brown and Linus note that a single Edmontosaurus can probably travel 40,000 miles within a single lifetime. Maybe longer. Elsewhere, by a huge river, the two Dromaeosaurus, now joined by a third pack member, climb up to a cliff looking over the river and look down upon and watch the herd of Edmontosaurus from above atop of the cliff. They're huge. The only chance the dromaeosaurs will have is to work as a team. As they know, Edmontosaurus are big opponents, even for the three of them. There's a river ahead, which the herd will have to cross. The river is enlarged and made faster and stronger by the melting ice. And the dromaeosaurs know that some never make it. As winter slackens its grip, meltwater begins to flow with great power. The herd must wade through this deep, fast-flowing water. Eventually, the Peanuts and the herd arrive at a section of the river with a still-frozen surface. The leaders try to select the safest crossing. The other members of the herd, including those with the kids and their dogs and birds on their back gather by the shore of the river as they were reluctant, at first, to cross. The herd follow cautiously. Young keep close to their parents. Putting a foot wrong here could cost them their life. The Peanuts gang watch as the herd slowly begins to head off across the river one by one. And they remained cautiously on their Edmontosauruses' backs. The adults awaiting their turn grow nervous. And this bottleneck gives the dromaeosaurs a chance.
With the herd held up at the river, the three Dromaeosaurus make their way down the snowy cliff face of the upland forest and begin to approach the herd. Their target will be the young. They rushed at some of the juveniles in the herd, harassing and intimidating them, as they stood by their elder for protection. But it wasn't long before even the adults were soon starting to worry. Panic begins to spread through the herd. And it wasn't too long before the Peanuts gang knew why. Every member is frantically running and wading through the collapsing ice of the river. What should have been an orderly crossing turns to chaos. In the chaos, one lone juvenile, who has been separated from his mother in all the commotion, stood on the bank of the river as he called out to his mother, who bellows out in response to his calls. Parents and young are separated. The kids, Snoopy, Fifi and Woodstock and his pals are aware of this, so they hop off their Edmontosauruses who have also made it across, and try to help the mother Edmontosaurus out with her current predicament. To make matters worse, the youngster has fallen into the river and is being carried along by the currents. The mother Edmontosaurus and the Peanuts gang followed the youngster down river and they soon arrived at a calmer section of it as the juvenile tries to climb onto the ice. Fortunately, the young hadrosaur manages to finally got a foothold and soon pulls himself onto the ice. He then reunites with his mother and they nuzzle each other. A lucky escape. Charlie Brown and Linus place their hands on the youngster's head and Heather, Janice and Sally hug him before they all rejoin the herd as it continues on. The column re-forms and continues its journey. Leaving the Dromaeosauruses on the other side of the raging rapids of the river. The dromaeosaurs seem to have missed their chance... but the river has done their work for them. There are always casualties. The three Dromaeosaurus rush down the rocky banks of the river to claim the reward of their combined efforts and the river's unforgiving power, a dead juvenile Edmontosaurus that didn't survive. The three begin feasting on the corpse. It's a feast, and more food than these hunters have had all winter. It will keep them all well-fed for a couple days, and could last them for weeks. The herd of Edmontosaurus, among them, the lucky juvenile and his mother, continues forward and onward on their migration route, along with their new travel companions. The Peanuts' voice guide says that in the ice world, seasonal opportunity is brief, spring is short, and summer will soon be over. There's a lot to be done before the challenges of winter return. So, the Peanuts say that they would like to see a lot more of it long before then.
A little while later, the gang has made it all the way to another, more warmer part, of the river, that runs through large exposed mudflats, which is why they're now back in their normal outfits. And they were very relieved that Spring was finally here. Downstream, as the rivers broaden and begin to slow, they start to drop their loads of silt, and a network of islands appears. The kids, Snoopy, Fifi and Woodstock and his pals trek across them and alongside the river as their voice guide then tells them that some animals have already seized the moment to assemble for the spring rituals. Spring, at last, has truly arrived. The gang soon come upon one of the mudflats that has a huge number of ostrich-like dinosaurs gathered on it. And they easily recognize them. Dozens of male Ornithomimus are preparing for the most important moment of their year. The gang walk casually amongst the small theropods and watch how they build their nests. These strange ostrich-like dinosaurs choose the safety of these islands to scrape out shallow craters, the first stage in making a nest. When the females arrive, they will choose to mate with the males who've made the best one. Marcie states the fact that some species of male modern-day birds build nests in the same way as this too, while Snoopy and Fifi examine and analyze one of the Ornithomimus and gets some facts and informational research on the species of dinosaur itself. Late arrivals find that space is already in short supply. They then notice one male among the crowd with a stick in his mouth as another male hisses at him and he heads off through the crowd. The gang decide to stick with him and follow him back to where his nest is by the river, since most of the good nesting spots have been already taken, which appears to somewhat make him a newcomer. The only space left is on the island's margin. And finding a place to nest is only just the start. The newcomer Ornithomimus looks around a bit, then sets to work on his nest. When eggs are eventually laid, they would need to be kept warm in a bed of vegetation. The newcomer then notices the gang and stares at them and then sniffs them before knowing that they are not a threat and turning his attention to the other male Ornithomimus and their own nests as one looks away. Finding enough nesting material is not easy... which is why some Ornithomimus resort to thievery. 
The gang watches as the newcomer carefully sneaks up to the nest as its owner heads off, and steals off a branch, before quickly heading back and placing it in his own nest. The kids were surprised by this, as they knew that some modern-day birds from their time have this same type of nesting behavior. The newcomer then turned back to the owner's nest. One advantage of arriving late is that your neighbors have already done the hard work. The other male returns and places a new twig, but then appears to realize something rather odd about his nest. When he turns his back, the Peanuts watch as the newcomer tries to sneak in once more, but when the other male turns around, already suspicious of nearby nest thieves, the newcomer stops in his tracks and looks around, pretending to be interested in something else. When the other male finally turns his back again, the thieving newcomer steals yet another twig from his nest and quickly dashes back to his own. An unguarded nest is too much of a temptation. The gang is intrigued by this. Their voice guide even tells them that, in colonies like this, thievery can be so common, that some nesting material, at one time or another, will have been part of almost every nest on the island. But robbery is risky. 
When the newcomer tries to sneak in for a third time, the other male finally spots him, and screeches and hisses at him while holding his feathered arms out. And the newcomer quickly backs off and stumbles a little as he does so. Caught in the act. This temporarily frustrates the newcomer for the moment. Just then, some bellows are heard, and the gang look down the river as a couple of Edmontosaurus wander by. They will eat leafy branches. So, you have to be able to defend your property. The newcomer Ornithomimus confronts and screeches and hisses at the two Edmontosaurus, while holding out his feathered arms. But the Hadrosaurs don't seem all that interested in anything to do with his nest, so, he soon turns back to it. It can take several years to perfect nest-building skills. The newcomer then turns to the other male he's been stealing from, who is now fully aware of his thievery. But success doesn't only rely on experience. The newcomer then looks around at the other males with their nests and finds yet another opportunity as he notices another male leaving his nest to collect more nesting material. In a crowded colony, there's always another potential victim. The gang then watches as the newcomer quickly rushes over to the nest, checks twice to make sure he isn't noticed, and grabs a stick. For Ornithomimus, these river islands will provide sanctuary for both the eggs and the young when they hatch.
Later eventually, the gang are now in a volcanic regional landscape in Eastern Russia, in Asia, where, further north, temperatures are lower and conditions are tougher. Yet that's where these enormous crested Hadrosaurs are heading to take advantage of one site in particular. One that has something special to offer. the herd of Hadrosaurs is made of up to 17 females, and so, the kids and their dogs and birds decide to hop up onto some of them and travel with them, to find out where exactly it is that they're heading. Their voice guide tells them that the long necks of these dinosaurs are particularly elegant, and give them their name. Olorotitan, "Giant Swan". Their calls are amplified by their head crests, which are hollow. The Olorotitan continues on through the ridge as they still make a precarious journey through the volcanic field, traveling in a thin line across a near dangerously-narrow path, flanked by numerous vents of toxic gases. They're heading for one of the world's largest volcanic regions. It's a dangerous and hostile place. But the Olorotitans return to it, year after year... because the volcanoes keep the ground particularly well-heated. So, this is where they nest. The Peanuts soon learn that the Hadrosaurs risk taking this deadly path every year to lay their eggs in warm, volcanic soil, laying and burying them in mounds. And their voice guide says that the warm volcanic sand serves as an incubator for their eggs. And a few weeks after the arrival of the herd, the eggs hatch. The mothers greet their newborn children by bringing them vegetation as food. Hadrosaurs look after their young with care. They bring mouthfuls of plants for them to eat. Each nest may contain over 20 youngsters. Being young, the juveniles appear quite playful. And needless to say, they are, indeed, adorned by the Peanuts girls and Fifi.
A timelapse then occurs as the Peanuts gang soon follow the Olorotitan herd as they head to an area to graze and feed on plants, such as patches of horsetails. The babies have arrived at a time of brief but rich summer plenty. Fueled by a sun that for weeks never sets, horsetails here grow fast and in sufficient numbers to feed the whole herd. These plants contain more nutrients than the lushest grass. And in the long summer days, the hadrosaur babies grow quickly. They can reach half their adult size in their first year. but they're still as playful as ever, with some even playing with their discarded eggshells, while others play withe the kids, as well as Snoopy, Fifi and Woodstock and his pals. Right now, these volcanic wetlands are the most productive places on the planet. Both above… and below the surface of the water. But that very productivity brings problems for the Hadrosaurs. And the gang as well, as they are about to find out. Warm, shallow pools are an excellent breeding ground for mosquitoes. Then, the gang heard the familiar sound of buzzing mosquitos and both immediately and nervously know what was happening, and soon, the mosquitos start to swarm the Olorotitans and the Peanuts gang. Every year, this paradise turns into a living hell. The mosquitos still continued pestering the hadrosaurs nonstop as they shook their heads in an attempt to shake off most of the mosquitos. The gang's voice guide tells them that Hadrosaurs have, surprisingly, thin skin, and so have little defense against bloodsucking insects. Marcie proves this true when she states the fact that while most dinosaurs have tough and thick scaly skin that stops mosquitos from biting them, though they do have softer parts, like the eyes or the insides of the ears, Hadrosaur skin is the least-thickest of all dinosaur skin, and that's why they have little use of defense against them. And when Lucy frustratedly, but dimwittingly, asks who is responsible for this pestering, Charlie Brown firmly and sternly tells her that she can't blame him, or even Snoopy, for it. And when she then asks who is to blame for it, everyone responds by annoyedly shouting back at her "NOBODY!", which nearly makes Lucy jump out of her skin, and startles the Hadrosaurs a little bit.
And it wasn't too long before everyone started to get irritated by the mosquitos. Constant irritation makes it hard to feed, and they become dangerously weakened. And babies can lose blood in life-threatening quantities. Eventually, the herd is forced to move on to escape the plague, as it worsens. And the Peanuts gang wastes no time in following them in suit. However, one of the baby Olorotitans, struggling to stand, much less walk forward, is starting to lag dangerously behind and drops to its knees as several mosquitoes target it. If the young can't keep up, their mothers abandon them. The group sadly watches as the youngster's mother has no other choice but to abandon him and continue forward to escape the mosquitos. Soon, the herd and their travel companions start hiking up the slopes of the volcanic hills of the valley. As they go higher, stronger winds bring some relief. But only for those able to walk that far. The Olorotitan herd and Peanuts gang continue up the slopes until they all soon arrive at the top of a peak with a rocky cliff, overlooking the fields and rivers below. Of the hundreds of hadrosaur babies born, only one in ten survive their first year. One mother looks over the surviving children as they play together, as well as with the kids, Snoopy, Fifi and Woodstock and his pals, and then nuzzles them. But those that do have a good chance of reaching adulthood. Just then, some squeaking was heard nearby, and the mother looks back and bellows out, as more whining was heard. And even the kids and their dogs and birds looked and saw something unbelievable. The youngster that was left behind and abandoned to the mosquitoes earlier, who had miraculously survived the mosquito plague, comes climbing up to the cliff, and Charlie Brown is so delighted by this, he pats the juvenile on the head and even gently picks him up and nuzzles him for a bit before gently placing him back down, and the baby then rushes over to his mother and they nuzzle each other too, as three of the youngster's siblings went up to him. Charlie Brown then gently strokes the mother Olorotitan's snout to calmly assure her that everything is okay now. By nesting in this volcanic valley, the parents give their young the best possible start in life. The Peanuts gang's voice guide then tells them that although the short and warm polar summer is a time of great plenty, it can also bring perils.
They soon find this out when they return to the far north of the Arctic in North America, in the height of summer, where warm air rises and becomes charged electrically. And that creates frequent and violent lightning storms. In the North of America, the lush growth fueled by constant sunlight has now been baked tinder-dry, which creates forest fires. The gang's voice guide then tells them that most animals flee from the flames. But for some, the disaster creates opportunities. And in one part of the forest that hasn't been hit yet by the flames, they soon come upon one example of those creatures in particular; a feathered dinosaur stalking around with embers flying around it as it was in no concern. This six-foot-long dinosaur, a Troodontid, is one of the smaller members of the Theropod group. It then curiously stares at them and then gently rubs its body against Charlie Brown's and purrs as it continues what it's doing. To find out why it's here during a fire, the Peanuts follow the Troodontid as it continues slowly walking in the midst of the flames, and tries to pinpoint the source of the sounds it hears, the calls of distress of other animals. Their voice guide tells them that its huge eyes give it acute sight, even in this smoky gloom. And for its size, its brain is one of the largest on the planet. It's the most intelligent, adaptable, and successful hunter in the Arctic. The gang then watches as It stalks through the forest and smoke and soon looks around through the blaze of fire, waiting for some of these other creatures to flee the flames and run straight into it. And he's not the only one here. At the fire's edge, Troodontids gather to prey on animals that are trying to escape the flames. The gang watch as the Troodontid patrols the edge of the fire, scanning for any signs of fleeing prey. Eventually, it then comes across a stick with a burning tip of smoking embers on it. Anything that spreads the fire creates more opportunities for the most ingenious Arctic hunter of its time. Realizing what it can do with this, the Troodontid picks up the burning twig in its mouth and runs off with it, taking it to and dropping it by a nearby tree that still seems unaffected by the flames. The kids, Snoopy, Fifi and Woodstock and his pals are amazed by this ingenious behavior. They then watch as several small mammals called Cimolodons rush by out of the woods, squeaking as they flee from the fire, and soon the Troodontid then ambushes and chases after them. The theropod dinosaur soon eventually snatches and grabs one of them with its jaws, pinning it to the ground, and shakes it, snapping its neck in the process. It soon holds its catch up in its mouth. Success. Eventually, summer ends shortly and autumn arrives early. With the short summer over, the forests that survived the summer fires start to change color. It is autumn's final flourish before the months of darkness begin. 
Sometime after that, the group ends up in Antarctica, in the southern end of the Earth. In the Antarctic, ice clings to the highest mountains even in the summer months. But now, with temperatures falling and the day's shortening, the polar winter is spreading once more across the land. Animals must now prepare for its return. Eventually, the gang end up in the prehistoric Antarctic forest and wander through its many trees, with Snoopy and Charlie Brown proudly leading the front. Sally, Franklin, and Peppermint Patty say that it's hard to imagine that this lush place is Antarctica, and Marcie tells them that Antarctica was very much different at this time, and even earlier, than it is in their time. The gang then heard some bellowing as they saw a trio of small Nodosaurid dinosaurs and start to follow behind them. Their voice guide then tells them that the southern hemisphere has its own species of dinosaurs. These three are young Antarctopelta, small plant-eating dinosaurs. They're also one of this world's most heavily armored animals. Even so, youngsters are safer together. One of the youngsters briefly stops to feed on some moss on a root. This far south, the plants on which they depend stop growing for months on end. The young Antarctopelta finishes feeding and hurries to catch up with the other two. And they continue through the forest as the Peanuts gang followed them. As winter approaches, these juveniles spend more time resting. And so, they prepare for their winter hibernation. Soon, they arrive at the entrance of a small cave. And the kids and their dogs and birds watch them prepare it. Sheltering together conserves heat and, therefore, energy. With powerful front limbs, they can enlarge this winter den. But each time they return, they've grown a little bigger. Their den seems a little smaller, and the brotherly bond... starts to wear a little thin. And this reminds Linus a bit about his relationship with Lucy, as he reminds her, himself, about it, backed up by everyone else, much to Lucy's chagrin. Unable to share the den with his brothers, the third young Antarctopelta sets off on his own to look for a place to rest. As his brothers sleep snugly in their den, the young Antarctopelta lies on the leaf-littered floor of the forest, comforted by his larger friends. For every growing animal, this is a vulnerable time. A time when they need to separate and each take its first tentative steps to find a territory of its own. Promised by Charlie Brown that they will help him find a winter den for him to hibernate in, the young Antarctopelta soon gets to his feet and they all start heading on their way.
The gang and their young Antarctopelta friend eventually make it to an open, stony field, and they begin to trek across it, coming across a migrating herd of Antarctic Hadrosaurs. Herds of Hadrosaurs are once again on the move. One Hadrosaur feeds behind a log and then turns to face the gang and the young Antarctopelta, who turns to it, and they stare at each other for a few moments. and soon, they continued on their separate ways. With little to eat, these huge herbivores return to look for food in warmer lands… leaving others to endure the freezing polar winter. Once more in a forest, the young Antarctopelta makes his way down the woodland's rugged grounds, along with the Peanuts gang. Finding a suitable territory can take animals far from the place where their lives began. It's a search that many will not survive. A good territory must have a place in which to shelter. Eventually, they arrive at a large cave opening, which they finds himself facing down. A cave, perhaps. Linus says that it looks promising, and Charlie Brown agrees with him. The young Antarctopelta begins to head down the rocks inside the cave as the Peanuts gang follow him. Even in the coldest months, the temperature in most caves hardly varies. Walking down the stony slope, the young Antarctopelta takes a good look of the large, warm cavern. But he is not the first to be attracted by this one. The kids, Snoopy, Fifi and Woodstock and his pals then notice and realize something remarkable. This cave glows. They follow the the young Antarctopelta deeper into the cave and then saw the glowing light. Their voice guide tells them that these are the tiny lures of fungus gnat larvae that produce light to attract their insect prey. The gang follow the young Antarctopelta to a flat section of cave floor in a corner of the cave. He looks around and seems to approve well, and then nuzzles Charlie Brown to thank him for keeping true to his promise that he made to him, and Charlie Brown pats him on the head before he then lays down and curls up to rest. He is immediately adorned by Heather, Janice and Sally before they all quietly say goodbye to him and then head back outside to let him sleep peacefully This is the perfect place for an Antarctopelta to escape the worst winter weather. He will be safe beneath these strange living stars… while outside, snow begins to fall.
Sometime later, the gang returns once again to the Arctic, in North America, where winter has, at last, once again, officially, returned. And now, they are all back in their winter clothes once again. In the coldest months, the far north of the Arctic can freeze into a spectacular winter wonderland. Not all dinosaurs choose to leave or to seek shelter. The largest have the strength to tough it out. In a clearing in the forest, the Peanuts gang have joined a herd of armored horned dinosaurs famously known for their armored heads. Pachyrhinosaurus. Two-ton herbivores with extravagantly armored heads. The gang watches as the herd feeds on snow-covered plants. They seek refuge in the forest, stripping the last leaves from dormant trees and rooting through ferns for fallen fruit. The gang then watch as two male Pachyrhinosaurus confront each other and one of them growls and bellows. The autumn rut is over, but less dominant males still try to push their way up the social hierarchy. But they've forgotten who's in charge. Just then, an older male, the herd's leader, rushes in and bellows out at the two less dominant males, thus putting them both in their place as they wisely back off, and also, impressing the gang. This old bull is still a formidable force and one that few dare to challenge. With a little help from Marcie, Charlie Brown and Linus state the fact that the brains inside their thick skulls are only a bit bigger than a bird's, but their reinforced heads make excellent battering rams. Battling males barely have time to eat or rest. With food now scarce, it's hard to rebuild strength, and injuries take longer to heal. To make matters worse... Just then, distant bellowing was heard and the herd was alerted. ...the Arctic's most powerful predator is always on the prowl.
The bellowing continues as it echoes throughout the forest. Nearby, a pack of feathered predatory dinosaurs growled as they were, indeed, on the prowl. Nanuqsaurus, a smaller relative of T-rex, and, in fact, the smallest of all the North American Tyrannosaurs, it's still just big enough to tackle a Pachyrhinosaur. And it wasn't long before two members of the herd and the Peanuts gang spotted the Nanuqsaurus. The word "Nanuq" immediately came to the kids, as they knew that they've heard that name somewhere before. Remembering that it's an Inuit name for Polar Bear, they quickly state the fact that Nanuqsaurus means: "Polar Bear Lizard". For these ancient adversaries, in these conditions, the battle will be resolved not by surprise, but by strategy. And soon, it wasn't too long before the whole herd of Pachyrhinosaurus was aware of the Nanuqsaurus as they begin to approach them. Amongst the trees, it's hard for the herd to stand as one. Individuals could be quickly isolated. So, the kids and their dogs and birds climb up onto some Pachyrhinosaurus as the nervous herd makes a tactical retreat to open ground. The Nanuqsaurs follow. Once they were out in the open, the herd began fleeing, along with the gang, and so, the Nanuqsaurus began to give chase and purse after them. But then at that moment, the winds pick up and a huge blizzard hits the area. As the chase continues, the herd soon halts to a complete stop and then instinctively forms a protective and defensive circle around the juveniles and the Peanuts gang as the Nanuqsaurus begin to circle around them as one growls. 
Out here, the herd will be able to close ranks and form an impenetrable wall of armored heads and muscle. They begin bellowing at the predators as they stalk towards them, looking for a weak spot. At times, when a tyrannosaur gets too close, one of the ceratopsians would charge out of the circle to knock them down, forcing them to temporarily retreat. The blizzard worsens. It's an uneasy standoff. These confrontations can last for days. The herd should be safe as long as they stick together. And the gang know that they'll be safe too, as long as they stay within the safety of the herd. But the Nanuqsaurs bide their time… and occasionally test for weakness. But once the blizzard has proven to have become too severe, both sides of the standoff hunker down and rest. And so do the kids and their dogs and birds. The blizzard now brings a temporary truce. But as soon as it's over, battle resumes. And so, the gang climb back up onto some of the Pachyrhinosaurus, knowing what's gonna happen next. In this test of nerve, all it takes is for one animal to break ranks... and panic quickly spreads. As the herd flees once again, the pack begins to chase after them again, as usual. With the herd on the run, the predators have a chance. The Pachyrhinosaurus herd ran as fast as their legs could carry them as the Nanuqsaurus pack continued to chase them, and the Peanuts gang then saw that one member of the herd was starting to fall behind. As the chase goes on, one tiring bull fails to keep up with the rest, until all he can do is turn and face his attackers. The herd then stops to and turns back to the confrontation, and the kids, Snoopy, Fifi and Woodstock and his pals watched the confrontation as well. And they knew well that this fight was only going to go one way. One Pachyrhinosaur has lost a battle. The pack of Nanuqsaurus then mobbed the Pachyrhinosaurus and, after a bit of a struggle, managed to bring it down and kill it. And they soon began to feed upon it, as it should keep them all well-fed for several days. But the war will go on all winter. The gang is sad to see him go, but they knew that this is just one example of how nature works. After paying their respects to the now-deceased herd member, the gang then says goodbye to the rest of the herd and eventually move on, just lust like they do. The animals here now face months of total darkness before the sun returns and brings relief to the extraordinary creatures in the world of ice of the Prehistoric Planet. 
=== Forests: ===
Sometime eventually, the gang, now back in their normal outfits, end up in the forests in South America, which contain some of the world's tallest trees. Their voice guide tells them that they can grow to a height of over 300 feet. But there are animal giants here too. And they soon find that out when something causes one of the many tall trees of the forest to tip over, breaking off many branches in the process, and hit the forest floor, thus, creating a gap in the forest canopy. And it turns out to be a small herd of large sauropods; Plant-eating dinosaurs. These are Austroposeidon. They're 80 feet long. And they have colossal appetites. Their teeth are used not to chew, but simply to cut. The kids, Snoopy, Fifi and Woodstock and his pals tag along with the herd and ride on one Austroposeidon's back. Their voice guide tells them that a herd like this one can consume ten tons of vegetation every day. They prefer the tender, young leaves that grow on the tips of the branches. The group's Austroposeidon then nears a tall tree. But if they find trees that are even taller than they are, they're not defeated. As their Austroposeidon nears the tree, the Peanuts were getting the idea of what it was up to, and so, they held on tight as their Austroposeidon presses its chest on the trunk on the tree and starts pushing as it jostles a bit. They use their great weight and their 8-inch-thick breastbone to simply push the trees over. The kids and their dogs and birds watched and held on even tighter as the forest titan continues pushing and lifts onto its hind legs as it keeps pushing and the tree starts tipping over. And so the tree came loose and comes crashing down, impressing the gang. Success. The Austroposeidon herd then gathers around the fallen tree and starts feeding on its branches. But life in the forest is always a battle. Especially when new space is created. Plants race to claim the light… And use every kind of method to gain the upper hand. The gap in the canopy is soon closed.
About three-and-a-half hours later, The gang ends up in the forests of North America. Their voice guide tells them that over three-quarters of the world's land is covered by plants and trees. This prehistoric planet is a green planet. He also tells them that many different species of dinosaur live in forests. And for one example, they soon come across and travel with a herd of the most famous of horned dinosaurs that is on the move. Triceratops, one of the Biggest in North America. The kids, Snoopy, Fifi and Woodstock and his pals hop up onto and ride some of the Triceratops as they travel with them. Linus and Janice note that they can be 26 - 30 feet long. And Charlie Brown and Heather state the fact that the huge frills on their heads, along with the three horns on their faces, are used for protection when they fight. But the gang's voice guide tells them that plants have defenses too. Poisonous toxins. Some Triceratops, including the ones the gang are riding on, temporarily stop to feed on plants. These are particularly dangerous for youngsters. And the gang then spot one baby Triceratops, at least a year old, appear from behind a tree stump as it looks to be climbing the side of it. This calf weighs only a 50th of the weight of his mother. And the plant's toxins could make him very sick indeed. The baby Triceratops soon starts feeding on some plants. But the gang's voice guide tells them that Triceratops have a way of dealing with such poisons. They use an antidote. The gang then notice a cave up ahead that the herd is heading into. One source of it lies in a cave to which they pay regular visits. Wondering why they've come to this cave, they stick with the herd as they enter it. This youngster, however, has never been in here before. Soon, the youngster's mother gently nudges him as she huffs, encouragingly urging him to continue forward. They have to find their way along a passage that, over many millennia, has been eroded by an underground river. They and their travel companions push even deeper into the cave as they looked around. 
Eventually, the Triceratops herd and Peanuts gang are now in a dark section of the tunnel with no light and the the gang had headlamps on at low level so they won't disturb their larger travel companions. They are now beyond the reach of light. They can't see a thing. Through the darkness, the herd carefully head down a ledge as they couldn't see in the pitch black cave through the tunnel. Among the herd, the young Triceratops blindly follows the adults. The calf must stick close to his family. But not too close. As the adults were then traveling so close that they were all getting tightly packed, the youngster ends up getting blindly jostled by them, and soon stood in place at the edge of the herd as they walked by and continue on, as well as the Peanuts gang. Soon, the youngster was all alone in total darkness, lost in the chambers of the cave, left to stumble around blindly as he wails out for the rest of the herd. Now, one wrong turn could be disastrous. Meanwhile, further away of the cave, unaware of the missing calf, the Triceratops herd, along with their travel companions, eventually emerge from the darkness and enters a section of the cave with some sunlight seeking through an opening to the surface, just out of reach. At last, the herd reaches the place they need to visit. And so, the gang hop off their Triceratops and wonder why they've come all this way to this location. They eventually get their answer when they then saw one of the Triceratops near one of the walls of the cave and then drags its upper beak on it, breaking pieces off before then grabbing and eating them. The gang's voice guide tells them that this is the antidote: a special clay. And the these are known as clay licks, and they're visited time and again. And this immediately reminds the kids of how modern day herbivorous mammals such as deer, moose, elephants, hippos, rhinos, giraffes, zebras, wildebeests, tapirs, woodchucks, fox squirrels, mountain goats, porcupines, and fruit bats use mineral/salt lick to deal with such poisons found in the plants that they feed on, and how macaws use clay on clay banks to neutralize the poisonous seeds that they feed on. The kids and their dogs and birds watch the herd mining for clay, but then notice one female realizing something. But someone is missing. Where is her calf? The mother Triceratops turns back to the cave and bellows out, hoping her youngster is near enough to hear her. Just then, yelping was heard from the cave and the youngster sounded like he was close. And soon, the baby Triceratops emerges out of the darkness of the cave. Luck was on the youngster's side. He then rushed over to his mother and nuzzled her. He is immediately adorned by the Peanuts girls, who all took turns hugging him before his mother escorted him over to a clay wall. Once he's lined his stomach with clay, he too will be protected from the poisons in the leaves on which he feeds. Soon, the calf starts to feed on the clay pieces his mother breaks off for him and the Peanuts gang watch as the Triceratops herd continues mining clay. Soon they will all head back to the forest and daylight.
Sometime later, the group returns to South America, where, in fact, very little of the sun's light reaches the floor of these dense forests. In Patagonia, the thick vegetation stretches unbroken for hundreds of miles. But occasionally, there are mysterious clearings, like this one. The gang soon enter the clearing and investigate it. Then, some low growling was heard and a shadow looms over some of the leaves of the clearing. Then, a blunt, bulldog-like snout lowers down and grabs a small scrub of plants. And the gang soon saw that the clearing's creator is was one of the most bizarre of all carnivorous dinosaurs. It's the work of a 2-ton, 12-foot-tall Carnotaurus. A male. The kids and their dogs and birds were amazed by the mid-sized theropod as he then lowers his head down and sniffs them before returning to what he is currently doing. The kids, Snoopy, Fifi and Woodstock and his pals watch as the Carnotaurus paws a piece of wood away with his left foot. Clearing this patch has taken him a long time. And it needs constant attention if it is to remain tidy. He then picks up another piece of wood in his jaws and then tosses it aside as he soon finishes his work. As for what the clearing is, the gang's voice guide tells them that it's a stage on which he can show off to females. Marcie, Violet, Patty and Schroeder mention that some modern-day birds, like the Lawes's Parotia, build stages and keep them clean to attract and impress females. All is ready, and he announces the fact. The male Carnotaurus then lowers his head and lets out a type of deep-rumbling guttural call and the Peanuts gang listened as it echoes through the forest. His calls are low-pitched and travel much farther through the dense vegetation than higher-pitched ones would do. And it wasn't too long before they were heard. At last, a female arrives. She's bigger than the male, and more powerful. The gang watches as the male Carnotaurus then twirls around as he starts his display; a type of courtship mating dance. Now, somehow, he must impress her. And he may only get this one chance. He lowers his front end and raises his tail, swaying it from side to side, before he then twirls around again. She watches him carefully. And so do the gang as he continues his display. If he is going to impress her, he must do so in the most extraordinary way.
He then held his head up in a motion, and then suddenly, at that very moment, he flashes out his tiny arms, showing a bright blue color on their undersides, surprising the gang. The male Carnotaurus continues his display with his tail held up and his arms out, before moving them and a sort of rotation motion and twirls once more as the display continues. He doesn't have huge antlers, nor a spectacular tail. But he does have a pair of tiny, apparently useless arms. And each has a ball and socket join at its base that enables him to move them independently. The male Carnotaurus continues his display still, and then finishes by rearing up and spreading his arms out to their fullest extent, showing the bright blue color on the underside. The female then approaches and sniffs him and she nears his arms. The Peanuts gang knew that it was the moment of truth of what might happen. In the end, throughout of no faults of his own, the female Carnotaurus then unfortunately turns and walks off, deciding that he is unworthy for some unknown reason. Not today. The male Carnotaurus, now dejected, lowers down. The gang is sad to see the courtship had failed, but they know that not every courtship display is successful. And Schroeder and Linus use this as another example to show Lucy and Sally that getting the love of your life is not as simple as they think it is. But then again, how could he have done better, who knows? Snoopy and Fifi comfort him before he then picks up a dry piece of fern in his mouth and walks off. For now, it's back to litter picking.
Later, the Peanuts soon find themselves in another new environment. This is East Asia. In these mountain forests, autumn arrives early. This is when many trees produce their fruit. And amongst the most highly-prized are the nuts of the Ginkgo tree. A bonanza for dinosaurs called Corythoraptors, who the Gang is currently hanging out with. Their voice guide tells them that although they have feathers, they're flightless, like most dinosaurs. One Corythoraptor looks at the the kids, before staring at Charlie Brown, and curiously cocking its head at him before it returns to foraging for ginkgo nuts. These have found a particularly abundant fall of fruit. But such gatherings can attract unwelcome attention. And when Linus wonders and asks what kind, they then get their answer when they notice that, nearby, a mid-sized Tyrannosaur with a relatively long snout is watching them, as well as the Corythoraptors from a distance. Qianzhousaurus, the top predator in these Asiatic forests. This is a female, over 30 feet long. She then starts to slowly and silently stalk towards them. Since they know she's not after any of them, the kids and their dogs and birds watch as the Qianzhousaurus stalks the Corythoraptors, as they were her target. If she is to catch a Corythoraptor, she'll have to get close. But not too close, that she might give herself away. There's not much cover here. But her prey have still not noticed her. Sensing that she was about to strike, the gang watches and waits for the moment of truth as the Qianzhousaurus is almost within striking distance as she froze and carefully watches the Corythoraptors as they continue foraging for nuts, and one keeps watch but hasn't noticed her. The Qianzhousaurus slowly stalks and freezes as the Corythoraptor lookout continues keeping watch but still hasn't seen her. The Qianzhousaurus then carefully placed her right foot on the leaf-covered ground softly. However, the Corythoraptors then looked alerted, as if they realized they weren't alone. And then, deciding that she is close enough, the Qianzhousaurus rushes out and charges at towards the flock as the Corythoraptors then squawked like crazy as they flee from the Tyrannosaur. The Qianzhousaurus roars as she missed a snatch of a fleeing Corythoraptor as the flock quickly ran as fast as their legs could carry them. And the Peanuts and Qianzhousaurus watch them vanish into the forest. She has failed. But then, most hunts, throughout the history of life, fail most of the time. When Sally notices and mentions the Qianzhousaurus' relatively long snout, which she gently strokes for that matter, Janice explains to her that Qianzhosaurus has an unusual long snout compared to other Tyrannosaurs, and that it's believed that it might've been good at catching fish. And Heather and Marcie explain that she happens to be a close relative to another species of Asian Tyrannosaur called Alioramus, and that her long snout hences her species' nickname: "Pinocchio Rex."
Above the forest, the sky darkens with storm clouds as thunder rumbles. And the wind drifts through the forests as leaves on the forest floor flew. As the seasonal winds strengthen, many of the trees in these temperate forests start to lose their leaves. Winter will be a time of hardship. Elsewhere in the forest, the Peanuts gang followed the female Qianzhousaurus, with Snoopy, Fifi and Woodstock and his pals riding on her back, as he was on the hunt again as she stalks. Nevertheless, a storm does create a brief opportunity for hunters. She's trying again. The Qianzhousaurus continues to slowly stalk through the forest. She's less conspicuous in the gloom, and the gusting wind is distracting. The wind continues blowing as the Qianzhousaurus slowly stalks silently. Nearby, the Corythoraptor flock were foraging through the leaf litter as they were more distanced from each other this time. And the Qianzhousaurus appears to have locked on one member that was more further away from the rest of the group. With Snoopy and Fifi still on her back, the Qianzhousaurus continues stalking towards the flock as a Corythoraptors continue foraging. The leaves rustled through the blowing wind as the Qianzhousaurus continues her approach and the wind silences each footstep she makes over the leaves. The targeted Corythoraptor then grunts having spotted the Qianzhousaurus and tries to flee as the Tyrannosaur then lunges forward and grabs it by its back. Both dinosaurs tumble and skid on the forest floor, causing Snoopy, Fifi and Woodstock and his pals to be thrown off the Qianzhousaurus' back, as the rest of the gang watched and then went over to them, and the Qianzhousaurus held on to the Corythoraptor's neck as she was still on her side as her victim tries to pull free. The wind blows through the forest as the Qianzhousaurus stood over her prize, now lifelessly on the ground. An 80-pound prize. The Qianzhousaurus then grabs and picks up her hard well-earned catch in her mouth by the base of its neck and holds it off the ground. All the more valuable, since winter is now closing in. The Peanuts then bid the Qianzhousaurus farewell before they then head off as she soon turns and heads off with her prize.
A little while later, the Peanuts gang return to North America, in another part of which, where a cloud layer gently drifts over a highland forest. In the forests of North America, there is an additional annual hazard for forest-dwellers. Fire, started by a strike of lightning. Somewhere in the forest, a fire that was caused by lightning burns through as it crackles through the forest trees and smoke drifts in the air. Soon, more smoke spews heavily over the forest as it is set ablaze. As it spreads, temperatures rise to over 2,000 degrees Fahrenheit. The kids and their dogs and birds watched the burning patches of fire through binoculars from high above, up on a raised mountainous ridge part of the forest. The fire continues burning through the trees as many stood covered in flames. Some rising very high. The flames rise several hundred feet into the air. The gang then heard the sound of a dinosaur bellowing out. They focused their binoculars and zoomed in on an area of spewing smoke as movement was seen near it. And they soon saw it was a fleeing dinosaur trying to escape the fire, which turned out to be an Edmontosaurus. Most animals flee. But this Edmontosaurus has a family to care for. She doesn't abandon them. The Edmontosaurus bellows out as moves away from the smoke as she has her 2 youngsters with her as they flee down the slopes of the mountain to escape the fire. Now they must keep one step ahead of the blaze until it burns out. 
Eventually, in the aftermath of the event, the fire has burned out completely, but the damage was already done as burnt trees stood in their place and smoke gently billows into the air as the gang wandered through the charred forest. The gang's voice guide tells them that this may look catastrophic, but, remarkably, some plants must be burned if they are to complete their life cycle. Nearby, some pinecones that survived the flames start releasing seeds. The intense heat is needed to open the cones of the pine trees... And release their seeds. A few pine seeds gently spiral down to the ground as a stick on a branch gently billows smoke. And only a few hours after the fire has passed, animals begin to return. Close by as the gang wander through the seeming-lifeless forest, a beetle that has taken shelter in a log from the fire crawls out. Beetles are among the first. The beetle stood on the burnt bark of the log. They start to lay their eggs. When they hatch, the larvae will be the first to feast on the near-limitless supply of dead wood. Marcie scientifically states the fact that beetles have been on Earth for millions on years, even before the dinosaurs. They watched a few other beetles as one crawls under a log, and then, the beetles find out that they aren't the only ones to return to the forest, however, as one beetle gets snatched by a species of dromaeosaur with light brown feathers and a stocky head shape. The kids identify it as Atrociraptor, a North American cousin of Velociraptor. This Atrociraptor is an opportunist. It then sniffs the gang and gently rubs its body against Charlie Brown's and purrs before walking off. They then follow the Atrociraptor as it wanders through the burnt forest. Quick to return when there's food on offer. The Atrociraptor then snatches up and eats another beetle. And there's something else to be gained here. The Atrociraptor then noticed a burnt branch with billowing smoke and went over to it, followed by the kids and their dogs and birds. The Atrociraptor then grabs a stick with a smoking tip in its mouth, and then held it under its right arm. Smoke is an insecticide... and it can help an animal to get rid of its parasites. The gang watch as the Atrociraptor held the stick under its arm, and then drops it and soon grabs it in its mouth again. But you do have to be careful. The Atrociraptor held the stick under its left arm, and then a growling sound was heard nearby as the raptor turns to it. The gang heard it as well as an armored dinosaur wanders through the forest. And soon, the Atrociraptor heads off to continue its activities elsewhere. The kids, Snoopy, Fifi and Woodstock and his pals then watch as the newcomer species of armored dinosaur reveals itself as it appears in view. A two-tonne Ankylosaur. Called Anodontosaurus. When the kids begin to wonder why he's here, their voice guide tells them that it also finds something worth eating after a fire. They watch the Anodontosaurus as it nears a burnt black stump, and then bites off a piece of burnt bark. Charcoal. It will bind with many of the plant toxins in its stomach, and neutralize them. Nearby, a large dinosaur bellows as it wanders through the forest. And the gang soon saw it was the mother Edmontosaurus and her offspring. The female Edmontosaurus is leaving the forest. The mother bellows as her 2 youngsters that have survived the fire followed her and the gang were relieved they were okay. Against the odds, she's lead both her babies to safety. The mother Edmontosaurus wanders through the burnt forest as her 2 youngsters followed her as she bellows out and the Peanuts Gang bids them farwell. They will have to find new pastures until the forest plants recover. Among the ash-covered ground, a shrub of plant starts to grow, signifying the eventual future return of the former glory of the forest.
Soon, the gang head back to central Asia, where Sunset shines over another forest. Even where fires are rare, trees do not live forever. And after they die, they become food for a very different kind of organism. Later eventually, the full moon shines through the dark night of the forest as insects chirping fill the night chorus. At night, some of them become eerily conspicuous. Down on the forest floor... fungi appear... and start to glow. On an old log, glowing fungus of all kinds shined green. The fungus grew as some grew into mushrooms. They produce their light by chemical reactions deep within their tissues. Other mushrooms shined bright green through the night. But why they do so is a mystery. It may be because the light attracts insects, which then help to spread the spores of the fungus. After setting up camp, the Peanuts Gang, now in their pajamas, and led by Snoopy and Fifi, wander through the ancient, night-filled forest as then a sound was heard close by. Here in central Asia, the nighttime forest is filled with strange sounds. The gang then look around as what sounded like snoring was heard. And they soon find a sleeping Titanosaur, which they suspect is either a Nemegtosaurus or Opisthocoelicaudia. Giant sauropods are asleep. When Patty wonder and ask if it is snoring, Charlie Brown says that it sounds like it is, and the gang's voice guide tells them that there are air sacs in their head and neck, which reduce their weight, but also amplify their snores. They soon leave the sleeping giant alone.
But not everyone is asleep. Close by, a shadow looms on the forest floor. As the gang wander through the forest, Charlie Brown and Heather noticed a small dinosaur nearby. For smaller creatures, it's safer to be out in the darkness than during the day. The others soon saw it and that it wasn't alone as it was a group of 3 small dinosaurs. They then got low and a little closer as they soon made out what species they were. These Therizinosaurus hatched just six months ago. Barely three feet long, they are only a tenth of their adult size. When Lucy and Peppermint Patty notice and mention the claws hidden behind the juvenile's wrist feathers, Charlie Brown and Linus explain that Therizinosaurus have incredibly large claws and that their name means "Scythe Lizard" for that. Marcie also notes that, in fact, Therizinosaurus has the longest claws of any dinosaur, or even creature, that has ever existed. Peppermint Patty notes that they're almost like the original Edward Scissorhands, and Marcie additionally notes that the crazy thing is that when the fossils of Therizinosaurus were first found, people thought the claws of Therizinosaurus were the ribs of a giant turtle. The gang's voice guide than tells them that their claws may look like daggers, but they're used more like salad servers… because these are plant eaters. And Heather and Janice accurately note that therizinosaurs, such as Therizinosaurus, and its North American relative, Nothronychus, are plant-eating members of the meat-eating theropod family group of dinosaurs. They then watch as one youngster feeds on some ferns. When Schroeder suspects that their claws would make good weapons, Linus says that they do in defense against predators like Tarbosaurus and Velociraptor, but that they also help Therizinosaurus dig for roots and pull down branches while feeding. This forest, however, has all kinds of food if you know where to look. The 3 Therizinosaurus youngsters then start licking something on the forest floor. Honey. And the gang knows that where there's honey, there are bees. Marcie notes that the first fossil of bees date back to 100 million years ago, so they all suspect that there must be a bee hive somewhere close by. They then see one on a low branch of a tree, with an old tree fallen and caught on its trunk. It's dripping from a bees' nest up in the branches. When the kids realize how low it is to the ground, their voice guide tells them that bees usually build their nests beyond the reach of ground dwellers, but this one is lower than most. And it's too good to miss. As the baby Therizinosaurs continue lapping honey, one youngster nears the old tree and grunts as it tries to hop onto its base. The bees buzzed in their nest as the baby continues trying to hop on the log. And soon, as the kids and their dogs and birds watch it, the baby eventually hops on the log and struggles to its feet. The gang's voice guide then tells them that unlike most dinosaurs, young Therizinosaurus can climb. Although they're not exactly experts. The gang watches the youngster as it tries to climb up the trunk as another tries to climb up the log as the first one struggles. The young Therizinosaur soon got to it's feet and heads up, but then slipped and grunts as it hits the ground as the Peanuts gang laughed a bit. And another youngster slipped and fell on it's back, and the third soon climbs on the log and keeps a good grip and starts climbing up the log. While the other 2 were struggling to join as they climbed up but soon slipped again and hit the ground. The bees buzzed as the Therizinosaur baby slowly nears the nest as the other 2 try to climb on the log. And the bees seems to have notice the approaching baby. The young Therizinosaurus nears the bee nest as another joins it as the first one nears it's head underneath the nest. Ready to lick any honey. Angry bees produce a Mexican wave to warn intruders to keep away... or suffer the consequences. The youngster nears the nest as a few bees flew, and then it manages to lick some honey as more bees flew around starting to swarm them. And the youngster squawks as the bees start swarming it and some were on it as they were stinging it. As it tries to get the bees off, it lost balance fell off the log and hits the ground, causing the gang to cringe painfully. One youngster soon rushed off to escape the bees' wrath as the other tries to shake off the swarming coat on its body.
Nearby, a giant wanders through the forest and it had immense claws. The 3 youngsters were soon aware of its presence and hid behind and underneath Charlie Brown. The Peanuts gang looked around and soon saw the creature as it was a full grown version of their little friends. An adult Therizinosaurus. The kids, Snoopy, Fifi and Woodstock and his pals all stare in awe at the real Giant Claw, and as well as the youngsters as they stare at the giant they will 1 day become, as it approaches them. It's huge, nearly 30 feet tall, and weighing five tons. The adult Therizinosaurus then notices the gang and sniffs them and is briefly petted by Charlie Brown and Heather before turning its attention to the bee nest. The gang watches as the Therizinosaurus attacks the bee nest as bees buzzed around and swarm its face. But the Therizinosaur wasn't even bothered by them. And then, with a simple swing of its 3 foot long claws, it knocks the nest off the tree and it drops to the ground. And the giant licks some honey and grabs a section of honeycomb. Nothing the bees can do deters this one. The Therizinosaurus soon heads off as the Peanuts gang and 3 youngsters watch it go. Soon, the 3 Therizinosaurus babies approached what was left of the bee nest in order to claim their share and start licking up the honey as a few remaining bees flew around. At last, a little treat. And a few more stings. The Peanuts gang watch as the young Therizinosaurus feed on their little treat. Sally says that she never thought dinosaurs would have a sweet tooth, and both Heather and Janice tell her that animals look for any kind of food they can find. After biding them farewell, they soon head off leaving the Therizinosaurus youngsters to enjoy their treat.
The next day, the gang returns once again to southern Europe, where the sun shines through another lush forest, as a dinosaur bellowing fills the forest chorus. Even by day, it's still dark in the understory of the dense forests, such as this one in Europe. The forest stood relatively quiet as many trees stood. Animals of any kind are difficult to distinguish. Yet, they're everywhere. The Peanuts gang wander through the forest as they haven't seen any dinosaurs or other mesozoic creatures yet. But soon, they spotted a mid-sized species of Hadrosaur. Telmatosaurus seldom breaks cover. Elsewhere in the dense woods, another small dinosaur wanders through the forest, and the gang soon spotted a small Ornithopod dinosaur. And equally inconspicuous... Zalmoxes, the last of a very ancient dinosaur lineage. The gang then saw it wasn't alone and was with a group of 5 and watch as the Zalmoxes traveled on a fallen tree trunk over a creek. This forest is one of their few remaining strongholds. Franklin notes that these Zalmoxes sure are small, and Marcie explains that that's because they're just babies, just around only 7 inches tall, whereas an adult Zalmoxes only stands nearly 3 feet tall. Seven inches tall, baby Zalmoxes are no more than snacks for many predators. But snacks are nonetheless worth eating... so they have to be cautious. The gang watches as the Zalmoxes group cautiously walked across the tree, and carefully keeping a watchful eye out for predators. Soon, feeling that the coast was clear, the young Zalmoxes rushed across the tree one by one.
But then suddenly the last one was suddenly snatched by a large beak, and the gang soon saw the owner of the beak, as it was a giant Azhdarchid pterosaur, as tall as a giraffe and close to the size of Quetzalcoatlus, but, slightly, a bit smaller. And the baby Zalmoxes yelps helplessly as the pterosaur tossed it further into its mouth and swallowed it whole. It then stares curiously at the gang for a moment, who identify it as Hatzegopteryx. Hatzegopteryx stands 15 feet tall. The Hatzegopteryx then heads off through the forest as the gang tagged along with it. Snoopy and Fifi even hitch a temporary ride on it. It is in fact, a pterosaur, a reptile with wings, that here, as it stalks through the trees, it has to keep tightly folded. The Peanuts gang tagged along with the Hatzegopteryx moving through the forest and it then slightly ducks its head under a tree caught against another. This forest, so rich in small creatures, is one of its regular hunting grounds. The Hatzegopteryx wanders through the forest as the Peanuts gang tagged along with it as they soon arrived to the edge of the forest at the southern coast of Europe. It stands on the southernmost edge of Europe. Waves roll and crashed on the beaches as the Peanuts gang were on Hateg Island, where Romania will eventually stand. And they and the Hatzegopteryx head out onto the beach. When Patty wonders and asks why the dinosaurs on Hateg are so small, and Violet notes that it's like a world turned upside-down, Marcie explains that Hateg doesn't have a lot of food for large dinosaurs like those that they all saw on the mainland, and so the dinosaurs that live here adapted over tens of thousands of years, and have gotten smaller and are so compared to their mainland relatives; an example of dwarfism. But Charlie Brown notes that Hatzegopteryx is the only giant here on Hateg, and Linus states the fact that it is the second largest species of pterosaur in the world. Their voice guide then tells them that this is the heaviest animal ever to fly, and there is nowhere else here where it could open its gigantic wings, which are over 30 feet across. The Hatzegopteryx then held its wings out and flaps them, before it soon preens and grooms its right wing, getting at an itch. Nearby, a herd of Telmatosaurus emerges from the forest, as well as a group of Zalmoxes. Many of the forest's permanent residents regularly come down here... because the plants are coated with sea spray and are a welcome source of salt. The gang watched the Telmatosaurus feed on coastal plants as they don't seen to mind them. Another Telmatosaurus was by a piece hanging driftwood licking the bark for any sea salt crusted on it. Then, 2 of the miniature giants of Hateg arrived on the shoreline as it was a kind of Titanosaur, Paludititan. Here, sauropods can meet one another, renewing family bonds... and creating new ones. The first Paludititan turns to the other as then the nuzzle each other. The sun sets as the Hatzegopteryx then held its massive wings out. But for Hatzegopteryx, the beach is a launching pad. Soon, the Hatzegopteryx catapults itself into the air and soon flies off as it squawks. And the Peanuts gang watch the Hatzegopteryx soar over the coastline and off over the Tethys Sea as the sun continues setting over the horizon. Now, his wings will carry him to yet another forest, where life proliferates more variously and more abundantly than anywhere else on our Prehistoric Planet.
=== Islands: ===
About two days later, the Peanuts gang are still in Southern Europe, having just braved through a tropical storm that just hit the area recently, and currently in their raft, paddling through a river that flows through a prehistoric forest as animal calls echo out. The mouth of a river in southern Europe, 66 million years ago. The gang notice several pieces of wood and other debris float on the surface of the water as it's carried out by the current. In the aftermath of a tropical storm, debris is drifting downstream. And amongst the wreckage, rafts of wreckage ripped from the land. In their raft, the Peanuts gang worked their way by the natural rafts. They noticed and saw one raft with a small pterosaur on it. For a weary pterosaur, this one may be a welcome place to rest... but it's far from safe. For a moment, it feels safe, flapping its wings as the raft drifts on peacefully. But then, suddenly, the water nearby was heard lapping as ripples were heavily stirred. The water stirs down as it got closer to the pterosaur and it's raft, and a dragonfly droning by flies off as then, sensing that something is wrong, the pterosaur grunts and squawks getting spooked quickly takes off. And the raft jostled from the wave action. And the pterosaur squawks as it flies off, having a lucky escape. Wondering what just happened, they brought out a periscope and they soon got a glimpse as they looked through the gloomy water. And before long, the shape of a familiar-looking creature was then seen.
A huge Mosasaur, a deadly underwater hunter, is looking for an easy meal. Realizing that it isn't a Mosasaurus, the gang suspect and speculate that the Mosasaur is a Prognathodon as it nears another natural raft. On the raft was a lone Zalmoxes as it stood on its raft, squawking. Such as this little dinosaur, Zalmoxes. The gang soon noticed the stranded dinosaur and remember those baby Zalmoxes they saw recently in their Forest adventure, two days back. They also theorize that he must've somehow got caught out during the storm. Underwater, the Zalmoxes' squawks echoed out as he held onto his raft. Staying here is too risky. He needs a larger raft, and quickly. The Zalmoxes continues squawking panically as he noticed a larger raft that looks more intact. The gang then saw as the Prognathodon underneath beginning to close in, and the Zalmoxes, growing more nervous, is beginning to face a grave risk as a fin from the Prognathodon's tail got closer like a shark stalking. And the Peanuts gang knew he had no choice. There's little choice but to swim for it. The Zalmoxes then makes a leap for it, and jumps into the water as the kids, Snoopy, Fifi, and Woodstock and his pals soon spotted him again, paddling frantically, as he desperately swims towards the bigger as fast as his legs can kick. Right behind him, the water stirs as the Prognathodon underneath begins to close in. But luckily for the Peanuts gang, the Zalmoxes got to the edge of the raft as he grunts, climbing up and made it just in time as it sniffs around. They soon got next to the raft and watched as the Zalmoxes looks around his new raft and finds something. He is not the first here. And they then saw another Zalmoxes who made it home here. Another castaway, a female. The female Zalmoxes turns to the newcomer male as he grunts and the Peanuts gang watched as their raft continues drifting downriver with the gang's raft tied securely. Their raft is drifting out to sea. The Peanuts gang and the Zalmoxes pair continue riding their raft and natural raft as the male lightly squawked. Marcie scientifically states the fact that natural events like this happens all the time in nature, and that, for one example, it's actually how the ancestors of lemurs got to Madagascar, intriguing Sally, as she pets the male Zalmoxes' head. Marcie also states that, overtime, the lemurs' ancestors adapted and evolved into the lemurs we know in Present-Day times. The gang's voice guide then tells them that sometimes, castaways on rafts like these are washed up on the shores of distant islands. If they're very lucky, this pair could become pioneers. The Peanuts gang then watch as the Zalmoxes pair nuzzle each other as they grunt, adorned by the Peanuts girls and Fifi. And may establish a new population, which eventually becomes a new species... unlike anything seen before. The natural raft and the gang's raft continue drifting out to sea as the sun sets.
Later, the Peanuts end up elsewhere in Southern Europe, as they floated and paddled in their life raft over to one of a few islands that stood by a shoreline similar to Vancouver in modern times as dinosaur roars echo out. Their voice guide tells them that the longer an island has been isolated, the more different its animal inhabitants may become. And that these small islands in Southern Europe are home to a strange, rather shy Hadrosaur. An animal bellow calls through the forest, and the gang wander through the trees searching for something, after securely parking their raft on the shore of the island. When Sally asks what they are we looking for again, Charlie Brown and Heather reminds her that their voice guide said that this island and its forest are home to a very special species of Hadrosaur, and Linus and Janice tells her that it's only found in this region. They soon got to the edge of the forest, and stood by the treeline and a grove of pine saplings stood as they then saw movement through them. Barely visible, a herd of small, strange, elusive, herbivorous dinosaurs with a clade of green color were seen grazing through the grove of pine saplings. A familiar duck-like bill bites off some pines on the saplings as they saw that it was the Hadrosaur they were looking for. Feeding amongst these pine saplings, Tethyshadros. They watch the Tethyshadros chewing on the leaves and lightly grunts. Then, one smaller Tethyshadros stood over the saplings chittering and grunting. The gang's voice guide then explains that, just a quarter of the size of its giant cousins on the mainland, it stands no taller than a human being. To which, Charlie Brown responds is 13 feet long and 770 pounds in weight, making them a small species of Hadrosaur, like their relative, Telmatosaurus from Hateg Island. A fourth of the size compared to the other Hadrosaurs of this time. With its unique serrated bill, it can forage among the tough vegetation. They watch as a Tethyshadros continues feeding on the saplings, and soon the herd begins to head off with youngsters following their parents as the gang tagged along with them. Hunters like T-rex have never reached this little island, so it should be a safe place for a mother to raise her brood. The gang continued traveling with the herd as a mother Tethyshadros nuzzles one of her infants and then bellows. But not necessarily. A spider web hangs from two branches of a sapling and a spider hangs onto the threads of it's silk-line trap. The kids, Snoopy, Fifi and Woodstock and his pals then realized as one Tethyshadros stood watch and grunts, acting as a lookout. They looked around to see if there was something else through the saplings as a Tethyshadros grunted. And one stood on its hind legs as another rushed off. They frowned as they looked back and then noticed something. They then saw a trio of silhouettes in the air approaching. The sentry Tethyshadros bellows out a distress call to the herd, and the other dinosaurs roared as they retreated. The kids and their dogs and birds each hopped onto a Tethyshadros for a lift and stuck with them as they then saw a flock of familiar giant pterosaurs, numbering around four males and three females, as the herd flees as one of them lands on the ground and snatches a youngster in it's robust-built beak. The other Tethyshadros, with the whole gang on their backs, flee as two other landed as a youngster grunts, fleeing for its life, as the pterosaur gallops after it. And the Peanuts gang knew well what species it was.
Hatzegopteryx. Giant predatory pterosaurs. The Tethyshadros herd ran for their lives chittering as the youngsters were more at risk as the two more Hatzegopteryx landed. The whole flock of Hatzegopteryx pursue after the herd as they ran. The best chance of escape is beneath the canopy of the taller trees. The herd and Peanuts gang quickly made it to the forest where the trees are too tightly-packed for their pursuers to get through, thwarting the pterosaurs, as two of the Hatzegopteryx were forced to stop at the edge as one bellowishly squawked in frustration. The Tethyshadros herd continues fleeing as the gang then got off their backs as they notice one turns back and lightly roars. It seems not all the Tethyshadros have escaped to the safety of the woods, however. Back in the cover saplings, a brood of baby Tethyshadros were hiding from the aerial hunters as they huddle closely, as they have got separated from the herd amongst the chaos. These small calves have been left behind among the saplings. From in the forest, their mother of the juveniles grunts out to them. Mother and young are separated. The mother Tethyshadros stood up on her hind legs calls out to her offspring. Due to this, one of the Hatzegopteryx realized that there are still some hadrosaurs out there that they can still hunt as it rumbled as the whole flock then stalked through the saplings scanning them for the juveniles as one squawked bellowishly. And the gang got to the edge of the forest watching them. Seeing this was a flock of four males and three females. Hatzegopteryx are very intelligent pterosaurs. Now that the element of surprise has gone, they change tactics. The kids, Snoopy, Fifi and Woodstock and his pals watched as the flock begin to spread out and and scour the clearing, keeping a sharp eye out. Spreading out across the clearing, they try to flush out any prey that might still be there. Amongst the saplings, the baby Tethyshadros were still hiding hoping the giant pterosaurs won't spot them as a Hatzegopteryx squawked bellowishly as one male was seen approaching dangerously close. The youngsters' best hope is to stay completely still... and not to run. The babies remained motionless as the Hatzegopteryx roars and wanders evermore closer keeping a sharp eye out for them. The Hatzegopteryx wanders dangerously closer, and soon, as it then got too close, the babies were forced to flee, screeching, as they took off. With their cover blown, one male Hatzegopteryx soon spots one running and rushes in and snatches it up in his robust beak. A female Hatzegopteryx approached him and tries to grab and take the male's hard-earned catch as he turns away and lifts his up as she bellowishly squawked and the male soon swallowed his prize whole as the female continues to pester him. The remaining two youngsters hurried through the clearing as one screeches as they head to the forest. Their mother roars as the Peanuts gang were near her as the youngsters rejoined their mother. These two are lucky to be back with their mother. One juvenile nuzzles its mother as the gang watches the reunion, and Charlie Brown then lighty scratches the juvenile's chin. Meanwhile, the Hatzegopteryx flock were still amongst the pine saplings as one bellowishly squawks, and soon, after what appears to be a brief conversation via the clacking of beaks, they catapult themselves in the air, one by one, and fly off. The island-hopping pterosaurs move on to try their luck elsewhere. One Hatzegopteryx, the last of the four males to take off, flies off with a caught Tethyshadros in his beak. With the pterosaurs gone, one Tethyshadros cautiously heads back to the pine sapling clearing and bellows out that the coast is clear. And the herd soon begin to forage again. The Hadrosaurs can return to feeding. The Peanuts gang soon say goodbye to the herd and begin to head off.
Eventually, sometime later, the Peanuts gang soon find themselves in a shallow sea, heading for the shoreline of one of the most remote islands of the Prehistoric Planet, Madagascar. Their voice guide tells them that the island of Madagascar has been separated from the African mainland for 80 million years. So long that most of its animals are now very different from any to be found elsewhere. A water reflects an animal walking by as it hisses, and through the brush it looks to be a species of crocodilian. And soon, a reptile with a short snout-shaped muzzle emerges from the plants as it hisses, and the gang watch it approach them, curiously. This is Simosuchus. The gang's voice guide then tells them that It's not a dinosaur but a miniature relative of crocodiles. One that lives almost entirely on land and is strictly vegetarian. One Simosuchus went up to a low-hanging leafy branch and bites off a leaf as it partly stood on another Simosuchus to reach it. It soon walks off as the kids and their dogs and birds watch them feed. Sally bewilderedly says that she can't believe that these crocodilians are plant-eaters. And Marcie explain to her that some crocodilians are herbivores, like one called Effigia, a Triassic crocodilian that looks more like dinosaurs. As they hang out with them and watch them forage, Violet and Patty say that they like their short snouts, which make them look like Pugs. And Heather and Janice tell them that Simosuchus actually means "Pug-Nosed Crocodile", and that they're like Pugs in Crocodile standards. One of the Simosuchus then turns the Peanuts gang and tilts his head, staring at them, and then curiously approached them. The Simosuchus sniffs each of them as Snoopy held his hand out with some leaves, and the small vegan crocodilian relative took them and swallows them. Simosuchus have tough, armored bodies which protect them from attack by the island's predators. So they can risk dropping their guard... sometimes. One Simosuchus lays while sleeping as another stood guard keeping a lookout lightly rumbling.
Nearby, from afar, a large animal with various wounds with dried blood rumbled as it stalks while hunting as it huffs. It is an Abelisaurid, a close cousin of Carnotaurus of South America, but sporting a single horn on its forehead. And this species is so fierce, it has been nicknamed, "the T-rex of the East", and is the top predator of Madagascar. Majungasaurus, Madagascar's top hunter. The Majungasaurus then spots the Simosuchus and Peanuts gang with their backs turned. And it observes and watches the Simosuchus, waiting for the right moment to strike. And one Simosuchus lightly rumbles, and the Majungasaurus did the same as it watches them and reveals its left eye, all gray. This particular female is blind in one eye, so she finds it hard to make a kill, and she's now very hungry. The Majungasaurus saw the Peanuts gang as she was unsure what to make of them, so focused more on the Simosuchus, and eventually, she charges. The Simosuchus spot her and screech, taking off, as the Peanuts gang looked and finally saw her and quickly jumped aside as the Majungasaurus rushes past them. They then got up and quickly chased after them all. The Simosuchus rushed by the bushes with the Majungasaurus right behind them as the Peanuts gang followed. But the Simosuchus have a plan as they rushed to some burrows. The Simosuchus have a network of escape routes that lead them to their underground burrows. One by one, the Simosuchus rushed to a burrow, but one male got to one already taken. Once inside, they block the entrance with their heavily-armored backs. The Majungasaurus finally caught up as she snorts and grunts, as did the gang. The male Simosuchus hisses as he rushes to another burrow that was already taken as well. And another Simosuchus rushed down to a burrow as the Majungasaurus charges as unlucky male and the Peanuts gang looked on. The unlucky male saw another Simosuchus rushing to burrow and hisses and rushed to it but only got his head through. This little male is unlucky. The Simosuchus pulled his head out and turns to the Majungasaurus as she growled and snarled, ready for a delicious Simosuchus appetizer. But he's not helpless. Reverse charges, tail swipes, and aggressive kicks. The Simosuchus then turns to his attacker and stand his ground, hissing at the Majungasaurus. He then shifts sideways confronting the Majungasaurus as she looked wary of making the final blow. And the gang watches in astonished bewilderment as he makes reserve charges like a porcupine, and swipes his tail with aggressive kicks. The Majungasaurus growled as she was wary to make a move as the Simosuchus grunts as he continues his intimidation display, hissing. And the Peanuts gang were truly amazed by this as it reminds some of them of how a Honey Badger would stand up to a Lion or a Wolverine confronting a Grizzly Bear. Soon the Simosuchus makes a break for it, and rushes to and heads into a burrow that hasn't been taken, and the Majungasaurus rushes after him. She jabs her blunt bulldog-like snout into the entrance, but was already too late. The hunter's snout is too broad to reach very far inside. The Majungasaurus soon lifts her head out from the burrow and growls frustratedly from hunger. And tilting her head sideways, she peeks through the entrance with her only good eye seeing the Simosuchus blocking the entrance with his armored back. And she leans down as she was not giving up so easily just yet. But just to be on the safe side, the Simosuchus digs even deeper. Some dirt was then kicked out of the hole as the Majungasaurus backs up and roars in frustration as she turns away and begins to leave. For the Majungasaurus, yet another hunt has ended in failure.
The Peanuts gang watch the Majungasaurus. They all agree that her kind is incredible, and Marcie even scientifically states that this is the dinosaur that proved cannibalism on each other, since some Majungasaurus bones were found with teeth marks matching those in its own jaws. But they also realize that she does look hungry and probably hasn't eaten anything in days, and wish there was something they could do to help her. Fortunately though, Snoopy and Fifi then have an idea that they might have something that could help as they reach in their pack and brought out three large pizza boxes, each revealing a meat lover's pizza with a lot of meat on them; Pepperoni, Ham, Sausage, Bacon, and even Meatballs. Then, as the wind gently blew by them, the female Majungasaurus has picked up the scent of the pizzas' meat and sniffs the air and then looks back. They gently placed the pizza boxes on the groung in front of them and backed up just a little bit as the Majungasaurus cautiously approached them and the three opened pizza boxes. The Majungasaurus briefly, but curiously, stared the kids and their dogs and birds, and then at the strange rounded food and sniffs them. The smell of meat was too much for her to resist, she then bites down on a slice and tossed it up into her mouth and swallowed it. And soon, she violently gorges herself on the pizzas, so furiously, it made Snoopy secretly jealous from that kind of hunger. Janice suspects that it must've been a week since she last ate. Sally wonders what could've happened to her eye, to which, Charlie Brown and Linus suspect that it must've been attacked when she was fighting either prey or a rival, whether it be a rival predator or another Majungasaurus. Soon, the female Majungasaurus finishes the pizzas as she grabs hold of four slices stuck together and tossed them further in her mouth and swallows them whole. Soon, she turns to the gang as they were a bit strange to her, but, nonetheless, kind and helpful to her as well, and even allows each of he kids to gently stroke her snout. After that, she soon turns and heads off with her hunger satisfied for now.
The Simosuchus soon crawls out of his burrow and saw that the coast was clear. Simosuchus is not the only evolutionary oddity to thrive on Madagascar. The Simosuchus soon walks off.
Later, the Peanuts gang explore another area on Madagascar. The island is also home to another group of very unusual animals. Mammals. The kids, Snoopy, Fifi and Woodstock and his pals wandered around as then notice something. They saw a shape ahead of them through the blaze of the heat as it was something familiar. They watch as the mammal wanders by as they got a look at it. This is a female Adalatherium. Marcie states the fact that she's a Cretaceous mammal, as big as a badger, unique to Madagascar. The gang's voice tells them that she's less than two feet long, but even so, she's still one of the largest mammals to have yet evolved. The kids and their dogs and birds follow and tag along with her as she crawls along a tree trunk. She spends most of her waking hours searching for food. The Adalatherium soon got to a burrow and heads in. The gang looks through the entrance of the burrow to see what she was up to. At the end of the tunnel, there are eggs... potentially a rich source of protein. They watch her sniffing the eggs. The Adalatherium sniffs the clutch, but then strangely lies down. But she doesn't eat this particular clutch. These are her own eggs, and this is her burrow. Marcie then explains that Adalatherium is one of the few mammals that remain still that lay eggs, just the only two modern-day, egg-laying mammals of Australia, the Echidna and the Platypus. The gang watch the eggs as then one stirs. The eggs are starting to hatch. Soon, one egg hatches as a newly born Adalatherium emerges from its shell. And the kids, Snoopy, Fifi and Woodstock and his pals watch in amazement as the other eggs hatched as the pups work themselves free from their eggs. The hatchlings' eyes have not yet opened, but instinctively, they head towards their mother to feed on milk. Soon, the babies gathered around their mother's stomach and start to suckle on her milk, just like any other mammals do. She produces it from modified sweat glands on her belly, and for now, it's all the food they need. They watch as the pups feed on their mother's milk before deciding to leave them be as they left the burrow for now.
Much later, at night, stars shined down over Cretaceous Madagascar, and, in about two months, the Adalatherium cubs have grown as they chittered. Two months later, and the cubs have more than quadrupled in size. The cubs wander around the burrow as their mother checks on them. To produce enough milk for them, their mother must herself eat a great deal. The mother Adalatherium soon climbs to the burrow entrance. So every night, she has to leave the safety of the den in order to feed. She soon climbs the tree trunk as the gang, now in their night clothes, watch her head off to find food. Nearby, the eye of a Cretaceous snake watches and slithers off. And the mother Adalatherium wanders around for food as Charlie Brown, Heather, Linus, Janice, Snoopy and Fifi follow and tag along with her. Her eyesight, like that of many burrowing animals, is not very sensitive. She relies instead on her acute hearing. Nearby, a familiar face was stalking upon. It's the female Majungasaurus from before as she is now out hunting at night. And if she hears something that might be dangerous, she stays perfectly still. The Adalatherium, Charlie Brown, Heather, Linus, Janice, Snoopy and Fifi remains motionless for a few moments and the Majungasaurus rumbled and soon turns away heading off continuing her night search for prey. Trouble avoided. As soon as she was gone, the Adalatherium continues her own search for food as Charlie Brown, Heather, Linus, Janice, Snoopy and Fifi follow and tag along. And soon begins digging for anything buried in the ground. She returns to searching in the earth for roots and seeds.
Eventually, the sun begins to shine once more as early morning returns over the dry landscape. And the mother Adalatherium returns to her burrow and lays down grunting as her cubs begin to suckle on her milk. The cubs are growing fast, and so are their appetites. Later, the mother heads back out to find more food and the Peanuts gang, now back in their original clothes, follow her. The female is now having to search almost nonstop for food. While the cubs lie down to rest. So her cubs are left unguarded for hours at a time. But the cubs are about to get some unwelcome company. Outside, a familiar-looking predator the gang has met before chitters as it wanders by dangerously close to the den site and around the hillside for anything to eat. Masiakasaurus. A hunter. And one particularly well-adapted for catching burrowing prey. The Masiakasaurus approaching the entrance of a burrow and sniffs it for anything to eat. And soon cranes its head through the entrance. With its long neck and narrow head, it can investigate any hole that might contain a meal. The Masiakasaurus backs away finding nothing inside, and heads up the hill and checks another hole but found nothing as it chittered and continues on. In the Adalatherium burrow, the cubs were still sleeping as they were unaware of the hunting Masiakasaurus outside. Back outside, the Masiakasaurus continues patrolling the area for food and was getting dangerously close to the burrow as the cubs were asleep unaware they are in danger. But hunters may themselves become the hunted. Then suddenly a large snake strikes out at the Masiakasaurus with a loud hiss and roar and coils around the dinosaur like modern pythons and boas would. The Adalatherium and the Peanuts gang had just returned as they saw the constrictor around the helpless Masiakasaurus as a lizard crawls on the tree trunk. Madtsoia, a snake nearly 25 feet long, squeezes its prey to death. The Adalatherium soon turns away to her burrow. This neighborhood has now become rather dangerous. The Adalatherium soon returns to her burrow as her cubs grunted and gathered as their mother lays down for them to feed. Later at night with the moon shining over, the mother Adalatherium heads out of her burrow, and this time with her cubs in tow as they have decided to leave for a new home. As night falls, the mother leads her young out of the burrow for the very first time. The Peanuts gang watch as the Adalatherium mother leads her offspring away from their original home as one cub looks back seeing the Madtsoia coiled up resting from the Masiakasaurus meal it had. And the kids know like its modern-day counterparts, the constricting snakes, the Madtsoia won't have to eat again for several weeks or more. And soon the cub follows its mother and litter. For now, at least, they must stay close together. The Adalatherium mother and her cubs head off together into the night. The gang then say goodbye to their Adalatherium friends and head off as well.
Sometime later, the Peanuts travel down south to Antarctica, as the sun rises over a snowy landscape. In the far south of the planet, on the islands of the Antarctic peninsula, winter brings months of freezing temperatures. Snowflakes gently flew down over a forest as the Peanuts gang, now in their winter clothes, wander through the snow-covered land. Here, too, being part of a family brings benefits. Lucy says that she can't believe that dinosaurs can actually make a living out here, to which, Charlie Brown and Heather reply that people usually think of dinosaurs in warmer weather, but they can make it anywhere. Just then, Pigpen's thermal tracker detects something. Its screen showed a thermal image of some kind of feathered dinosaurs curled up together, grunting, as they slept. A thermal camera reveals a huddle of glowing bodies. As they wonder what species of dinosaur it is, they do note that they are able to maintain body heat just like birds and mammals can. Through the thermal image, a head of a dinosaur lifts up and looks around. Their voice guide then identifies the dinosaur. Imperobator. Hunters. The Imperobator looks around and got up as the gang then saw it was a pack of five. Like most dinosaurs, they are warm-blooded. The other Imperobators lift their heads as they begin to get up. But to stay warm, they need a lot of food. So they must make a kill every few days if they can. The Imperobator pack then curiously sniffed the kids and soon heads off to hunt as the gang followed. Fresh snow muffles the sound of their footsteps, enabling them to move undetected through the forest in search of prey.
Up ahead of them, a small feathered plant-eating dinosaur was forging for food. A Morrosaurus. A plant-eater for whom winter is inevitably a very hard time. The Morrosaurus chittered and wanders around the snow-covered forest. The Morrosaurus continues forging as a dinosaur roaring echoes through the trees, and the little dinosaur looks around as some snow drops from a branch. And the Morrosaur scans the trees checking for predators. Nearby hidden among the branches, the Imperobators were getting ready for an ambush. Imperobators specialize in hunting such prey. The Peanuts gang were also nearby as they saw the Morrosaurus, and Peppermint Patty says that they are quite common in Antarctica. The Imperobators chittered out as the Morrosaurus then runs off through the forest as the Imperobators chased after their target as they hurried through the snow. And the kids and their dogs and birds caught up on their snowmobiles. The Morrosaurus is faster than its pursuers. The Morrosaurus rushed through the forest passing by the trees. But it's outnumbered by the pack. The Peanuts gang watched as the Morrosaurus hurries through the snow and the Imperobators were beginning to catch up. The Imperobators' long-feathered tails give them remarkable maneuverability. The Morrosaurus keeps running as the chase goes on as they soon got to the edge of the forest. The chase has reached the very edge of the forest. And ahead of them, was a large lake. Beyond lies a frozen lake, half a mile wide. The clear, open space could give the faster Morrosaurus an advantage. Snow on the iced surface of the lake stirred from the wind gently blowing. But the frozen surface is treacherous. The Morrosaurus chittered as it got to the edge of the frozen lake. And was cautious of the ice. Behind him, the Imperobator pack begins to close in on their target. With the Imperobator closing in, it isn't much of a choice. The Morrosaurus looks back, seeing the pack right behind it, and with no other choice, it runs off across the ice. The gang follow behind the chase as the Imperobators pursue their target, growling, as the Morrosaurus zig-zags across the ice, trying to throw off the predators' attention. The Morrosaurus growls as it changes direction again as the Imperobators were still on the dinosaur's tail. The Morrosaurus then zig-zags again, but then slips nearly stumbling as it regains its footing as one Imperobator snarls closing in, but slips and hits the ice as it screeches. But the Imperobator was quick to recover and get up. A misplaced step, a chance for the Morrosaurus to sprint beyond the predators' reach. The Morrosaurus continues running as the Imperobators soon give up the chase and watch their prey run off. But this is an island, so hunters and hunted will almost certainly meet again.
Further north away from the Antarctic, a small island stood over the shallow sea. Some islands are so small, that they have no large land-living residents. But they may nonetheless get visitors. A large pterosaur soars in towards the island and soon lands on the small island's beach as the Peanuts gang, now back in their normal outfits, had just arrived. And they saw it was a familiar face. Hatzegopteryx. Having a good look at him, they saw that instead of brown, this particular individual was a light grayish color, darker gray on his neck, and his beak as a blue color. It could mean he is an older male. This male has arrived carrying a 40-pound Tethyshadros carcass. A prize from a recent hunt. The Hatzegopteryx placed his catch down on the ground and lightly rumbles as he wasn't eating it. And then he stood with his wings spread out, and the gang looked all around him and saw how huge he was as his wings easily dwarf those of most modern-day birds. He is 15 feet tall, with a wingspan of over 30 feet. And Charlie Brown notes that he is Europe's biggest pterosaur, and almost as big as Quetzalcoatlus. And Linus notes that he is also the heaviest and second largest flying animal to ever live; almost 500 pounds. The Hatzegopteryx then folds his wings back on all fours. And the giant pterosaur then reaches an itch on his right wing. Hatzegopteryx are Europe's top predators. But this male has come here to reveal another side to his character. The male Hatzegopteryx then drags his bill on the sand by the Tethyshadros body drawing a line around it. The gang then watch as the pterosaur grabs a branch and brought it back over, and soon drags more and soon finished. As they wonder what he was doing, Linus theorizes that it looks like he's made a display of some sort, and as the Hatzegopteryx then held his wings out, their voice guide tells them that he has constructed a display to make it clear to any females passing overhead that he is looking for a mate. But he might have a very long wait before he gets a response. Hours went by as the male was still at his post with his compadres, and soon chittering was heard as another Hatzegopteryx as arrived. And soon nears the island and lands on the beach as it bellows and growls. At last. A female. And they know it's a female since she has a much smaller head crest. The male watches as the female approaches him and the gang. She seems interested, but a little more persuasion might be necessary. And he needs to be careful. One well-aimed peck from her beak could quickly bring his mating season to an end. The kids and their dogs and birds watch as their male lowers his head down and picks up the Tethyshadros corpse. His display must demonstrate that he has the good genes that her young would do well to inherit. Moving a little closer, the group watched as the male Hatzegopteryx held the corpse in his beak and holds his head straight up. The dead dinosaur suggests that he's a good hunter and carrying it here has proved that he's a strong flyer. The male Hatzegopteryx then placed the Tethyshadros body back on the sand as the female stares though looks to be unimpressed still. But if she is impressed, she isn't showing it yet. The male then lightly clatters his beak and held his head up. Time to produce some new evidence of his eligibility. The Hatzegopteryx holds his head straight up and makes a rumbling call with his throat. Head lifts invite her to come closer. The male continues on with his display, and the female, looking interesting, begins to step closer. And the Peanuts gang quietly watch as he continues. Now, she gives him a little encouragement. The male continues his display as the female begins to clatter her beak as a sign that she's starting to get really interested. And they both moved their heads in perfect unison as they turn to each other, and soon nuzzled each other. And the gang were amazed by this, and seeing the softer side to Hatzegopteryx. And they both soon held their heads up as they continue their courtship. A synchronized dance creates trust between them. They continue their display as they lightly clatter beaks, and held their heads up.
But they then just got some unwelcome company. Another male. He's much younger, but he could still be a rival. The younger male begins to approach as the older male confronts him as the female stood by. The older male then charges, squawking bellowishly, as the female flies off, and the two males clashed beaks at each other as they fought. And then the older male bites the younger male's right hand as he groans. And he pulls free as he soon flies off as the older male bellowishly squawks. That's him dealt with. The older male turns around, but saw the female was gone. Disaster. The female has left. A bitter blow for the old male as waves rolled on the beach. He may have lost his chance. The old male got back to his display stand, and a Hatzegopteryx was heard chittering as he looked back. And the Peanuts gang saw it was the female as she didn't flew off too far. She's back. The female Hatzegopteryx approaches the male and the Peanuts gang. Seeing off a potential rival might even be another point in his favor. The male held his wings out briefly, and folds them again as they nuzzled a bit. And then the male held his wings out again. He continues from where he left off. The gang watch him as he continues his display, and soon turns to the Tethyshadros corpse as the female turns to it.One last reminder of his strength. With the female's attention on the carcass, the male begins to move around and behind her. And this is his only contribution to fatherhood. The male screeches as the next generation is now underway as the waves continue rolling on the island's beaches. It's all over in just a few seconds. Later, the female Hatzegopteryx soon flies off. But it's the start of the next generation of these giant flying hunters. They watched as the female Hatzegopteryx flies off away from the island. And then they watch as the old male held his wings out and starts the courtship ritual again, ready to attract more females. Their voice guide tells them that islands like this may only be small, but like countless others around the world, they bear witness to crucial moments in the lives of some of the most unusual creatures on the Prehistoric Planet.
=== Badlands: ===
This is the largest expansive lava to flood the Earth for 100 million years. The Deccan in Central India, a hellish place, and certainly not where you'd expect to find dinosaurs. And yet, giants risk their lives traveling here. Isisaurs. And all are females. Lava has been flowing in The Deccan for so long, that in places, it is a mile thick. Every spring, females leave the safety of their forest home to make a perilous journey into these badlands. They can pick a safe route through cooled, hardened lava... but there are other dangers here. In addition to the steam, a deadly mixture of carbon dioxide and hydrogen sulfide spews from volcanic vents. In the cool, pre-dawn air, these heavy gases sink to create a barely visible suffocating blanket. Just a few lungfuls can kill. But Isisaurs have one crucial advantage. Their long necks can keep their heads above this blanket of poisonous fumes. But ahead lies a place where this will be hard to do.They're entering a low-lying area where the deadly gases are particularly thick. And for these females, something is already wrong. And worse, as the sun rises and warms the air, the gases swirl even higher. Long necks can no longer protect the herd. They must escape to higher ground and quickly. The climb is steep, but should bring fresher air. Relief, at last. And ahead, their final destination. A volcanic island in the sky, rising high above these treacherous badlands. The huge crater, a caldera, provides a safe, communal nesting ground. The surrounding sea of poisonous gases helps to keep predators away... and the in-built geothermal heating makes it an ideal incubator. Each mother digs a seven-foot trench in the warm sand, to hold over 20 melon-sized eggs. The eggs are safe in the caldera for now, but this is just the beginning of their story. In a few months, hundreds of tiny babies will hatch to face this desolate world. If any are to survive, they'll need a perfectly-timed change in conditions.
The badlands of the Prehistoric Planet tests even dinosaurs to their limits. This strange landscape carved by scouring winds and vast ancient rivers might appear empty of life. But here in Asia, hidden in these narrow canyons... is a new family of Velociraptors. The young are just a few weeks old. It might seem that, in such a barren place, they face an uncertain future. Their survival relies on a strange event not here, but miles from their home. Across the baking desert lies a forest trapped in a sea of sand. A change in the seasons brings rare water to this region. Huge stands of poplar trees mark its arrival with a flush of nutritious leaves.A magnet that draws many hungry animals. Long-necked Nemegtosaurs are joined by Mongolian Titanosaurs. And with them, much smaller Prenocephale. But one thing stands in their way. This immense plateau. And the only way to reach the forest is through this maze of canyons. As they enter, the herd becomes nervous. It's a good place for an ambush. The Velociraptors are waiting. But they can't possibly tackle a titanosaur. Success will depend instead on other hunters on the prowl. Tarbosaurs. Asia's version of Tyrannosaurus rex. As the predators approach, panic spreads. Only the Prenocephale can escape to higher ground. And this is what the Velociraptors have waited for. Now, the Velociraptors can finally spring their ambush. At last. Working together, they have secured a meal for the whole family. The Tarbosaurs have also had success. For predators, it's actually a time of plenty. And for the Velociraptors, the perfect time to start a family.
Having clever, caring parents can give youngsters an excellent start. And here in the badlands of Asia, there are few more dedicated dinosaur parents than these. A colony of nesting Corythoraptors. A few days ago, females laid eggs on these circular mounds. But the job of brooding them falls to the males. And that is not easy. Exposed to the midday sun, the eggs would soon cook. But the fathers use their broad tail and fallen feathers to keep the nest shaded. And pay a heavy price. Enduring hour after hour in the searing heat. At last, in the cool of the evening, the males can step away in search of food. This is where nesting in a colony brings benefits. Instead of all leaving at once, the Corythoraptors take turns. So there's always a neighbor keeping an eye out for danger. But even this neighborhood watch can't guarantee their safety. A female Kuru Kulla, a relative of Velociraptors. She is extremely hungry, but wary of the Corythoraptors' powerful beaks and claws. But she has one key advantage. Her night vision is better than that of the owners of the nests. If she's quiet, she can sneak into the colony undetected. She picks her target carefully. This is her chance. But not to attack. This predator is also a thief. She will eat as many eggs as fast as she can. Time's up. She's been discovered. One last egg to take away. She now has a chance to enjoy her stolen egg in peace. But this thief shares her spoils. With these purring sounds, she calls her young. Her chicks are not long out of the nest themselves. They need to learn that this strange, new object is food. And discover how to break into it. Maybe their beak. Or perhaps, a claw. Success, perhaps more by luck than skill. But still, a vital lesson for this next generation of egg thieves.
In the badlands, the relief of cooler nights is all too soon followed by the return of the intense heat of the sun's rays. The temperature on the surface of the sand can soar to over 160 degrees Fahrenheit. Any water here soaks away or evaporates in seconds. This is one of the driest places on earth. Without water, no animal can survive. Yet, this is home to these young Tarchia. They are desert-living Ankylosaurs. Heavily-armored, with huge, clubbed tails. Dark patches protect the Tarchias' eyes from the glaring sun. And this is the sound of Tarchia's very own air-conditioning system. Their large nose cools the air as it leaves the body, condensing and so conserving valuable water with every breath. It allows them to survive long periods without drinking as they search for a meal. The high temperatures here create scouring winds which carve the rocks into extraordinary shapes. But they also strip the ground of soil. Some plants, however, manage to take root in cracks between the rocks. Any meager mouthful is worth competing for. With every minute, the sun climbs higher. Soon, all shade will be gone. And even these masters of the desert welcome a drink sometimes. Like many nomads, the Tarchia have a mental map of the desert and can travel across empty landscapes with unerring accuracy. They remember the rare places where there are natural springs. Desert oases like this one. A lifesaver for animals that can find them. Prenocephale. Tensions often run high around an oasis... but a display of strength can prevent a dangerous battle. In the end, the Prenocephale are little more than annoying. But an adult Tarchia is another matter. Especially one almost twice the youngster's weight. It wields a club weighing almost fifty pounds. If this comes to a fight, the juvenile can't win. But reinforcements are on the way. The pair are reunited. Now, there are twice as many swinging clubs for the adult to deal with. He decides that, perhaps, there is enough water here for everyone to share. The young Tarchia can finally drink in peace. But they may not be able to enjoy their rest for long. In badlands, conditions can change with astonishing speed. Rising summer temperatures fuel electric storms hundreds of miles wide.
Here in the Deccan, these seasonal storms cause a shift in the wind direction. And around the caldera where the Isisaur females laid their eggs months ago, the poisonous gases have now blown away, providing a critical window of opportunity. There are strange sounds coming from beneath the sand. Baby Isisaurs are calling to each other from inside their eggs. It helps to synchronize their hatching. The babies are relatively tiny, less than a foot long. There's nothing to eat, except their mothers' dung. Surprisingly, it's very nutritious and important to the hatchlings in other ways too. It introduces healthy bacteria into their guts, and it also contains pheromones that, like smells, will enable them to find their mothers' herd. It will lead them to the safety of the forest. But the journey isn't easy. The winds may have changed in their favor, but many dangers lie ahead for the young Isisaurs. Hot springs and bubbling pools of liquid mud. A deadly trap. After two days of trekking, the babies' reserves are running low... but their mothers have come to the rescue again. Small plants have taken root in the cracked lava, sprouting from seeds dropped in the mothers' dung. But a new danger is heading their way. Now the wind has cleared the toxic gases, the door opens for predators. A Rajasaur. With so many babies out in the open, this could be a feast. Cracks in the lava are the only possible hiding place. More Rajasaurs arrive. Despite the dangers, hundreds of babies succeed in reaching the forest. Here, they will live together, hidden in the undergrowth, for several years. Until finally, they are big enough to join their mothers' herds. With luck, the females among them will return to this crater in years to come to lay eggs of their own. Like many animals that live in such inhospitable places, the risks will be high. But there are also great opportunities in the badlands of the Prehistoric Planet.
