In this game, Rotatatron appears as a boss battle at the end of the Sonic's Figure Skating Spectacular event. During this event, each of the four characters participating must get near Rotatatron and carefully time their jumps in order to hit its eye. This cycle will then repeat, except this time, Rotatatron shoots red shurikens at the player(s). After enough hits have been dealt, the four characters skate out into the center of the rink. Once in position, the player(s) must spin in order to perform the Final Color Blaster with the aid of the Wisps collected over the course of the event to deal one final blow to Rotatatron in order to destroy them for good.
