Sonic the Hedgehog arrived here in an attempt to rescue Amy Rose from Dr. Eggman. Eggman told him that he only got Amy back if he beat his newest Super Badnik, Metal Sonic in a race. Should Sonic lose, he would be destroyed by a laser fired from the Egg Mobile. Sonic accepted, raced the deadly robot, and won, resulting in the destruction of Metal Sonic and the rescuing of Amy. Eggman threatened Sonic that he would still win once he got his UFOs back, prompting the hedgehog to find the Time Stones before the evil doctor did to put an end to his scheme.
