Rick built a city called Valt, which stretched millions of miles across the continent of Al-Pikune, and millions more miles up into the heavens and millions more miles down into the Earth. Valt had tremendous walls built of toffee, which enclosed a population of over 90 million creatures and their friends. Valt could also transform into a kangaroo which secreted tasty chocolate eggs in its pouch, and children came from miles around in order to get one of these eggs of Valt. Under the leadership of Rick, Valt dominated and spread across the entire planet, which grew and diversified immensely. Valt also began the contruction and colonization of space and the production of several popular board games.
But it was not meant to be. One of Valt's space colonies revolted, and millions of huge alien ships made of tapioca pudding assaulted the Earth and carried off many of its inhabitants to distant galaxies to work as slaves and pool attendants. Rick's tapioca children then launched sypothonic missiles at the Earth, destroying it completely, and went on to dominate the rest of the universe for many years.
The various chunks of Earth which were large enough to support life floated around freely in space and each gradually became dominated by one species.
