The Chaos Loop Challenge Playset from Hot Wheels Monster Trucks features two ways to play: race through the Slime™-dripping loop to reach the adjustable catch-cup or launch straight through a wall of Slime™ to reach the cup. Load the included 1:64 scale Hot Wheels Monster Trucks Mutant Chaos Wreckin' Wolf into the slam-launcher, then turn the loop to choose the setup. Kids can add the Slime™ for an enhanced obstacle or race without it. It's compatible with Speed Snap Track �" add more track for an increased challenge �" and 1:64 scale cars. Additional track and cars sold separately. Colors and decorations may vary.
