Get ready for a high-speed showdown with the Hot Wheels Monster Trucks Mutant Chaos Ooze Monster Playset. Mutant Rhinomite must take on a giant Mutant Chaos monster, racing through its open mouth and avoiding its swinging fists to win the battle. Wind up the playset's lever to activate the monster's moving arms and jaws, then use the slam-launcher to send the included 1:64 scale Mutant Rhinomite roaring down the track. The challenge gets even messier when you add the included reusable green Slime, which oozes from the monster's mouth as the truck races through the action. When the truck hits the monster at the right moment, the beast is knocked out and the playset can be reset for another round. Children can enjoy the full slime experience or play without Slime for a less messy version of the challenge. The set combines racing, moving parts, and imaginative monster-battle play in one exciting Hot Wheels Monster Trucks adventure.
