Earth

Earth is the planet on which most, if not all, characters in the Rat Movie series live. At the end of Timeline A, an unknown event related to the Mayan Treasure was triggered, resulting in the planet's destruction. Disappointed due to the fact that the Noah's Ark Toothbrush was on planet Earth, the Cats turned back time and stole the Mayan Treasure before the Thieves or the Rats could find it, keeping it safe so that the world-destroying event could not be triggered again. This is the main event that separates Timeline A from Timeline B.
