Dr. Eggman: "Welcome to the recap page for Sonic Colors, offering light speed descriptions of each of the game's events. Perfect for dirt-poor tropers with no money or patience to spare on getting or playing the game for themselves."
Dr. Eggman has constructed a series of planet-sized theme parks, dubbed "Dr. Eggman's Incredible Interstellar Amusement Park", in an apparent attempt to make amends for all of his wrongdoings. Sonic and Tails, suspicious that this is a ruse for a new sinister plot, take a space elevator up to the theme park. Their suspicions are confirmed when they meet an alien creature dubbed "Yacker", a member of the alien race known as "Wisps". According to Yacker via a translator Tails invents, Eggman has captured other members of his race and are using them as a power source for his theme parks.
Travelling from one planet to the next and rescuing Wisps along the way, Sonic and Tails learn the true reason behind the construction of Eggman's theme park: it's a front for the construction of a mind-control weapon, powered by corrupted Nega-Wisps.
Eggman, undeterred by Sonic and Tails' efforts to free the wisps, decides to activate his mind-control weapon and take over the world right away. Unfortunately, a piece of wreckage from a previous battle causes the weapon to malfunction and explode, creating a massive, growing black hole. Angered, he confronts Sonic with a mech powered by the Nega-Wisps, but the captives are freed from the machine, allowing Sonic to defeat the mad doctor again, just at the black hole's force sucks him in.
Just as Sonic is about to be engulfed by the black hole, the Wisps save him, transporting him and Tails safely back to Earth and stopping the black hole. As Sonic and Tails bid their farewells to Yacker and the Wisps, Eggman is seen floating helplessly through space, with his robot goons Orbot and Cubot pushing his Egg Mobile in the endless drift of space.
