Twelve fairy-tale locations are the setting for a variety of events as players take the role of Shrek, Donkey, and more to compete in the Shrek: Smash n' Crash. Racing to the finish line in such vehicles as the Puss N' Boots bull and Humpty Dumpty's egg cup, gamers must maneuver around windmills, moving gates, draw bridges, and opponent-thrown items in an effort to complete "Tournament," "Cup Challenge," "Quick Race," "Time Trial," and "Battle" competitions. Each character comes equipped with unique attacks and combos designed to dissuade opponents from finishing first, either with a quick smack to the head or by knocking enemies completely out of their vehicles. Power-ups are scattered throughout each course as well, and players can collect and use such items as pixie dust, ogre strength, and swamp gas.
