The Ordovician Organisms (South Park)

The Ordovician Organisms is an upcoming South Park episode which features the paleozoic ancestors of the modern day characters.
==Premise==
475 million years before the events of Cartman Gets an Anal Probe, the single-celled organism/amoeba ancestors of Cartman, Stan, Kyle, and Kenny are living beneath superocean Panthalassa during the Ordovician era. In the beginning of the episode, they hatch from eggs at the Mariana Trench, but as the episode progresses they attempt to make their way to the Great Barrier Reef, but as they begin their odyssey they encounter many marine beings that threaten their lives such as giant squids, angler fishes, pacific viperfishes, giant spider crabs, six-gilled sharks, stingrays, etc. They once even hide in a brine pool to hide form predators out of desperation. Despite never meeting anyone else but themselves, the four organisms were biologically wired to seek out their friends and family, and they eventually make it to the reef and unite with them. In the last five minutes of episode, the four main characters begin to follow an amphibian creature in the ocean, and it had just evolved from a form of fish. The amphibian then made its way to the surface, with the four main characters clutching onto its tail, with all the organisms following their lead. The organisms then evolved into humanoids that strongly resemble their modern descendants, and then crawled onto land with the amphibian leading the way, until it is crushed by a Tyrannosaurus.
==Trivia==
*The 2D hand-drawn animated sequences for when the characters were underwater were produced by both Neko Productions in Burbank, California and South Park Studios. The episode combines traditional animation with computer animation for when the characters move onto land.
**The animation also bears a striking resemblance to the cartoon segment in the opening scene of the "Minions" movie. 
*In the opening scene of the episode, we get a microscopic look at a pitch black screen with amoebas floating around, some even resembling stars on a night sky. There are circular amoebas hitting each other around, until a bigger amoeba push around the smaller ones, cutting one of them in half. Four glowing organisms in a jelly-like substance float on-screen and observe. Suddenly, an even bigger red amoeba with sharp teeth gobbles it up, and the four main characters grow eyes at the same moment. The four organisms pop out of their eggs and follow the amoeba off-screen until it is devoured by an even bigger blue organism. Prehistoric Stan, Kyle, and Kenny grow fins and tails and proceed to follow the blue organism. Prehistoric Cartman twitches erratically until he grows a fin and tail as well, following his friends once he grows them. The four organisms swim in a distinctive order, left to right; Prehistoric Stan, Kyle, Kenny, and Cartman as they follow the blue organism in a straight path as it pushes and gobbles up plankton, small amoebas, and even a dwarf lantern shark until a large tentacle grabs it. A large one-eyed golden octopus with a unibrow plays with the blue amoeba for about five seconds before devouring it. The four main characters laugh at its suspense until they notice a giant moray eel sneak up behind it and open its jaws, the four main characters clutch onto each other in fear as the eel eats the octopus. All of this, along with the final clip of all the organisms underwater, pays homage to the opening scene of the "Minions" movie. 
*The characters were omnivores, meaning that they ate both meat and plants. Their herbivorous diet consisted of seaweed, seagrass, kelp, algae, sea grapes, halimeda, etc. They also ate a variety of fish, such as salmon, herring, and sardines. They also ate squid, octopuses, shrimp, krill, jellyfish, mussels, clams, scallops, shellfish, crabs, lobsters, prawns, oysters, and barnacles. They were also scavengers, consuming dead carcasses when available, such as plesiosaurs and sea dinosaurs. Their favorite meals however were seals, walruses, and right whales. This is because these animals possessed nutritious insulating layer of blubber, which was a rich food source for the main characters and this would provide them several days worth of energy.
*Years are actually going by while the characters are beneath the sea, and they change size many times throughout the story. When they first hatch from eggs near the Challenger Deep, they are are about the same size as plankton, and when they grow fins, they are about the size of of a pygmy seahorse, but slightly smaller, and hence why Cartman's ancestor was able to fit in the pouch of a sea horse. When the characters grow hands and feet when they reach benthic waters, they are about 4-7 inches tall. Rays from the sun can also be seen on the floor, although the surface is not discerned. It is also worth mentioning that the characters actually move their legs when they walk. When they leave the ocean, they grow to their typical size for South Park characters.
**Their designs also change multiple times, most notably their eyes, their bodies also change color occasionally. When they are in the midnight and twilight zones, their eyes are larger and are cylinder shaped. Before they go into hiding, their eyes become more round and resemble ovals. When they make it to the Great Barrier Reef, their eyes become permanently round for the remainder of their time underwater. All organisms have a distinctive look and do not have identical faces like the typical South Park animation, and one can distinguish male and female as all the female organisms have eyelashes, while the males do not. Prehistoric Butters is the only male organism with visible eyelashes, but he only has two, as opposed to the females who all have three eyelashes. 
*When the characters were underwater, they possessed several abilities that helped them survive:
**Glowing in the dark: When the main quartet characters were in the hadopelagic, abyssal, and bathypelagic zones, they had possessed a natural phenomenon that allowed them to glow in pitch-black conditions and help them navigate in total darkness. This is called bioluminescence.
**Asexual reproduction: The main characters were shown to rapidly regenerate their limbs and reproduce by "budding". One example was when a angler fish bit off one of prehistoric Kyle's arms, and he regenerated his lost arm in a matter of seconds.
**Camouflage: The characters had the special power of camouflage to be able to blend into their surroundings, which was very helpful to use when hiding from predators.
**Echolocation: In juxtaposition with bioluminescence, another way the main characters navigated in pitch-black conditions were echolocation. They had developed the ability to use echolocation, often known as sonar, to help them see better underwater. They also used this ability to locate both predators and prey, and this trait is achieved by sending out a wave from the mouth. When the sound waves hit an object they produce echoes. The echo bounces off the object and returns to the characters ears.
**Shapeshifting: The main characters were also shown to shapeshift, allowing them to morph into different shapes and can also disguise themselves as any person they want. They can also mimic the sounds of the animal they shapeshift into.
**Enhanced Senses: The characters had very sharp senses. This power is seen when they hear the faint screams of a predator miles away from them. Also they rapidly noticed the presence of another being in a brine pool, which was an electric eel.
**Speed and Agility: The characters were shown to swim at great speeds, even once appearing to have caused a sonic boom when taking off. They used their speed in conjunction with their acrobatic skills, allowing them to escape rather brutal confrontations with little difficulty. One notable achievement was when the characters were following amoebas in the ocean and when they were trying to flee from a pursuing anglerfish, they seemed to travel from the abyssal zone to the bathypelagic zone in seconds, meaning that they traveled 53,400 feet and therefore moved at a speed of about 36409.091 mph. 
**Strength: The characters were shown to be tremendously strong for their size, cable of holding their own against other larger organism species. They were shown to carry heavy objects, such as boulders and branch-like materials. When swimming at full speed, they easily knocked back multiple fish.
**Stamina and Endurance: The main quartet were shown to swim for very long periods of time without signs of fatigue. Their bodily tissue is substantially harder than regular organisms that gave them some degree of invulnerability.
