[Description] Often called the Spin Attack or just the roll in later games, pressing down on the D-pad while moving will make Sonic curl into a rolling attack. He'll remain in this position until you jump or slow down. The speed of Sonic's movement while in spin mode is based on how fast you're moving when you launch it, and also on the terrain Sonic rolls along. [Name]
