Kids can feel the power of crashing and smashing in the palms of their hands. Drive the included Race Ace monster truck into the 4 smash spots to overcome obstacles and win the challenge. The set also includes one crushable car and can connect to other sets to create a Hot Wheels Monster Trucks AChildrena Smashers world (sold separately).
