The game revolves around the story of the astrophysicist antagonist, Baron Aloha, who removed giant pieces of land from Crater Planet by using his "gigantic land-lifting machines" in order to turn them into his own private resorts. Aloha also removed and hidden away the twelve Jet Pods that propel each world. The residents of Crater Planet consequently call for help, and in response the Universal City Hall sends one of their agents, a mechanical bunny named Robbit. Robbit must explore each world to retrieve every scattered Jet Pod, stop Aloha, and save Crater Planet from desolate emptiness.
