The evil Dr. Eggman (also known as Dr. Robotnik) happens upon an alternative dimension where some odd fowls known as Flickies have the power to go anywhere. In order to get help in his hunt for the Chaos Emeralds, Dr. Eggman morphs the Flickies into automatons that will help him chase down his desirable gems. Of course, it's up to our loved blue hedgehog, Sonic, to step in and save the day. Jump into this 3D escapade as Sonic or his brother Tails, and roll up the blessed rings to help free the Flickies and get the better of the wicked doctor.
