Stone Ages (Thymewarped)

Stone Ages is the 1st world in Plants vs. Zombies: Thymewarped, unlocked right after beating the Player's House tutorial. As the name states, the world takes place during the Stone Age; a prehistoric era of time after the Ice Age when stone was used as the primary material for tools and buildings. The world here appears to take place outside a cave, which early humans would adopt as their homes.
This world contains Boulders, the first environment modifier of this world. Boulders block straight-shot projectiles from hitting the zombies and a tile to plant, absorbing 500 damage before disintegrating. Grave Buster can be planted on boulders to destroy them, while obstacle-breaking plants like Maypop Mechanic and Bamboo Spartan deal extra damage to them.
During the second half of the world, Campfires are present on the lawn. Campfires act like temporary Torchwoods, igniting peas and similar projectiles that pass through it while stopping plants from being planted down there; while damaging zombies that walk through it. As time goes on, the fire will begin to die down until the campfire disintegrates. Hot Potato can be planted on the campfire to stoke the fire and keep it up, while certain explosive and fire plants can reignite it as well. Ice-based attacks such as those thrown by Winter Melon and Missile Toe will instantly extinguish and destroy the campfires so players will need to be careful about what plants they bring into levels. Certain zombies can also destroy these campfires, such as Wheel Roller Zombie and Club Zombie, so players will need to keep an eye on these zombies.
After beating Day 12 of Stone Ages, players will get access to Ancient Egypt and can choose to continue pursuing Dr. Zomboss in THIS time period or travel further in time.

==Order of events==
After Day 5 of the tutorial, the player meets Crazy Dave along with Penny and travels to Stone Ages in order to catch up to Dr. Zomboss. After beating Day 1, the player unlocks the Map of Space-Time-Ness and gets to search around the map while being introduced to the Travel Log as well. During Day 2, the player is introduced to Plant Food and is given a tutorial on how to use it. The player unlocks the Cabbage-pult after Day 2. When the player beats Day 4, the player unlocks the Time Almanac.
At the start of Day 3, Penny explains how the plants given will be on conveyor belt, and how they'll be given by special delivery.
At the start of Day 5, Penny begins to explain how cavemen used stone weaponry to hunt prey, and Crazy Dave insists on using Wall-nuts instead as they're much more dangerous. When the day ends, Penny does agree that using Wall-nuts as weaponry is a good idea, but should not always be used.
At the start of Day 8, Penny explains that the player MUST use a specific selection of plants in order to maintain the balance of time.
At the start of Day 10, Crazy Dave notices the endangered Sunflowers and asks Penny about them, to which Penny recommends that they be kept safe from harm otherwise all of reality could collapse. 
When the player defeats Day 11's wave, a flaming torch is rewarded; the first ever fire discovered. On Day 12, Dr. Zomboss writes a note before the huge wave attacks, insisting that HE discovered fire for them and that they should stop interfering with his time interference. After this exchange, the player will go on to defeat the Caveman Gargantuar and Penny explains that without the help from others, life WILL find a way to evolve.
After the Gargantuar wave is beaten, players will get the option to continue playing through Stone Ages levels or travel through to the next time period to start squashing Dr. Zomboss there.
At the start of Day 19, Crazy Dave explains they can't spend anymore sun, they have to use the leftover sun from previous levels and will have to make one last stand with the zombies.
At the start of Day 24, Dr. Zomboss has no idea how Crazy Dave, Penny and the player managed to survive this long just by using plants found in the time period, but warns them to stay out of the way. After the massive Gargantuar attacked is defeated, Crazy Dave lets Zomboss know that they'll keep on fighting him and Penny suggests that they continue to track him down in future time periods, and maybe they'll come back here one day.
During the Frostbite Caves outbreak, Penny warns that the zombies of the ice age have arrived. Crazy Dave wonders if they're coming in from the cold, and Penny believes that this might be true as they might be trying to figure out a way to evade extinction and that the player must put things right. As they play, Penny detects the Bird of Paradise and explains how she can help with her ability to carry zombies away but they must protect them from the new Fossilised Zombies that are erupting from the ground.

===Brain Busters===
Main article: Brain Busters
====Special Delivery====
Main article: Special Delivery
Special Delivery is a Brain Buster that is a conveyor-belt level with the plants given via said conveyor-belt. Being a conveyor-belt level, no sun and sun-producing plants will be given. It is playable on Day 3.
====Wall-Nut Bowling====
Main article: Wall-nut Bowling
Wall-nut Bowling is a Brain Buster exclusive to Stone Ages, featured on Day 5, Day 15 and Day 23. The conveyor belt gives the player three different versions of Wall-nut to use, a regular Wall-nut, Explode-O-nut and Giant Wall-nut; the player must attack the zombies by placing the nuts behind the red line, from where they will roll forward, damaging zombies and ricocheting off of them as normal.
====Save Our Seeds====
Main article: Save Our Seeds
In this Brain Buster, the player is forced to survive the wave of zombies and protect the endangered Sunflowers. The player will fail the level if the endangered plant(s) dies. It is featured on Day 10.
====Locked and Loaded====
Main article: Locked and Loaded
Locked and Loaded restricts the player to using only pre-chosen plants in order to win the battle, featured on Day 17. In some levels, the selected roster may include plants the player may not have unlocked yet - in which case the player gets an opportunity to play with those plants as a demo. Locked and Loaded serves as a reference for a certain weapon in real life, where once it is armed, it should not be disarmed anymore.
====Last Stand====
Main article: Last Stand (PvZ2)
In this Brain Buster, the player is given a large amount of sun at the very beginning to plan their defenses before launching the zombie attack. The player may also be given a number of Plant Foods to make use of during the level. Generally in this game mode, sun does not fall from the sky, and all sun-producing plants are prohibited. It is featured on Day 19.
===Prehistoric Pandemonium===
Prehistoric Pandemonium is Stone Ages' Endless Zone and it is unlocked after beating Stone Ages. It is the first Endless Zone that can be unlocked and much like the original Survival: Endless, players will need to keep updating their defences as the levels get harder and harder in order to survive; and will encounter stronger versions of previously-encountered zombies like the Rockhead Zombie and Boulder Roller Zombie. The layout of boulders changes with each new attempt.

==Trivia==
*Stone Ages originated from the Plants vs. Zombies: All-Stars world, Primitive Tribe, although the lawn has been stretched to have five lanes instead of three.
**Most of the zombies are carried over from that world, with the exception of Beehive Thrower Zombie and Mammoth Rider Zombie; the latter of which appears later on in Thymewarped.
*The lawn for Stone Ages uses the Concept art of the Chinese version of Plants vs. Zombies 2's Primitive Tribe.
*Stone Ages replaces Ancient Egypt as the first world.
**Its All-Stars counterpart, Primitive Tribe, is also the first world in that game as well.
**Cabbage-pult is also unlocked here instead of in the tutorial.
*This, Frostbite Caves, and Jurassic Marsh all have a prehistoric setting.
**The order in which you go through each of those prehistoric worlds is reversed, as the Paleolithic period came after the Ice Age which in turn came years after the Jurassic period.
*Caveman Flag Zombie and Wheel Roller Zombie don't have images and are currently using placeholders.
