Sonic, Tails and Amy Rose attempt to rescue Cream the Rabbit and her pet Chao Cheese from Doctor Eggman, who has already retrieved the seven Chaos Emeralds. While attempting to destroy his base, one of Eggman’s robots inadvertently shoots a machine containing the Emeralds, which activates the “Chaos Control” technique. This teleports Sonic, Eggman (and his robots), Tails, Amy, Cream, and Cheese, as well as Big the Cat (with his pet frog Froggy), Rouge the Bat, Knuckles the Echidna, and the Chaotix (a detective crew comprising Vector the Crocodile, Espio the Chameleon, and Charmy Bee) to Earth, the parallel-universe version of their world with humans. Sonic is chased by the police, escapes into a mansion’s swimming pool, and is rescued by a twelve-year-old boy named Chris Thorndyke, who lives there with his movie-star mother Lindsey, corporate executive father Nelson, scientist grandfather Chuck, African-American maid and chef Ella, and Japanese butler Tanaka. Chris tries to hide the anthropomorphic friends from his family until Cream accidentally reveals them, but they all build up a good rapport with Chris’ family and with Chris’ friends Danny, Francis, and Helen.
