The diabolical Dr. Eggman has hatched another plan for world domination! He has built an amazing interstellar amusement park, floating in space around Sonic's home planet, bursting with incredible rides and attractions. However, all is not as it seems as Dr. Eggman has abducted an alien race called Wisps and is harnessing their colorful energy to fuel a sinister plot. Soon after arriving at the amusement park, Sonic discovers he is able to use these mysterious alien forces to help the Wisps escape! The alien Wisps featured in the game each have a unique Color Power that, once freed, Sonic is able to absorb while speeding through the various theme park inspired planets. Sonic will need all his speed and skill as he faces this test, but, empowered by the alien energy, it's a test he'll pass with flying colors!
