This exciting new vehicle, Knuckle Headz is a unique new vehicle play pattern. Fueled by a powerful pull-back motor, Knuckle-Headz simulate medieval jousting with a few modern twists. Define the battlefield, aim your vehicle at your opponent’s, pull back for maximum momentum, and let ‘em zoom toward each other. Direct hits result in the loser’s head popping off about 12 inches. Reset your spring-loaded character heads and face off again.
