The Hot Wheels Monster Trucks Chaos Loop Challenge track set offers two ways to play: race through the Slime™-covered loop to reach the adjustable landing cup, or launch directly through a Slime™ wall to reach the cup. Attach the included 1:64 scale Hot Wheels Mutant Chaos Wreckin' Wolf Monster Truck and rotate the loop to choose your configuration. Kids can add Slime™ to create a more challenging obstacle or race without it. Compatible with Speed Snap Tracks – adding more tracks for increased challenge – and 1:64 scale vehicles. Additional tracks and vehicles sold separately. Colors and decorations may vary.
