In this high-tech Sonic platformer, the evil genius, Robotnik, has discovered that the mysterious native birds of Flickies' Island, called "flickies" have a power that lets them travel to different dimensions through large gold rings. Robotnik decides that they could be useful for finding the seven "Chaos emeralds", which are very powerful. Robotnik transforms the flickies into robots, which Sonic must destroy in order to save his friends.
