Crash test dummies Spare Tire, Daryl, and Bumper have been kidnapped, and it’s up to Spin and Slick to rescue them. Play alternates between stages with control of Slick/Spin. Slick moves around on his feet while Spin wheels around on his unicycle legs, which is momentum-based in movement. Stages are varied in look (funhouse, warehouse, junkyard, docks, circus) and the enemies and environmental hazards usually match.
