Special Stage Sonic is a playable object in Sonic the Hedgehog, appearing only in the Special Stage. Unlike the Sonic object seen in the normal stages, this version stays in ball form at all times. In this form, Sonic can be made to move side to side, and jump off of blocks/walls. Beyond that, his movement is dictated by the stage itself.
