In The Incredible Crash Dummies, the player plays as the two titular Crash Dummies, Spin and Slick, on their adventure to save their kidnapped mates Spare Tire, Darryl, and Bumper from the Junkman.[1] It starts with Slick putting himself back together after a car wreck, while Spin checks the Crash Test Center, a research and development place for machines which is the location for the first stage's first section.[2] He finds that Bumper was kidnapped in the Test Area by one of Junkman's helpers ("Junkbots") who is holding him hostage in the sewers;[2] thus, the level's second section consists of both dummies saving Bumper and having a boss battle with the henchman in the process.[3]
The player must finish levels and overcome obstacles,[4] jumping off from towering houses, driving breakneck lawns over life-threatening ski slopes, a ride on rocket-propelled target missiles, piloting spaceships, and other tasks.[5] Throughout the 27 stages, the player has to prevail against ten opponents.[6]
