Using this Monster Jam playset is easy and fun. First, set up the ramp and dunk tank. Then, take the 1:64 scale Monster Mutt Dalmatian truck and launch it down the ramp towards the warm - water pool. You'll see the truck's muddy exterior wash off, showing a clean design. You can aim different 1:64 Mud Blasters Monster Jam trucks at the pool too. After that, if you want to bring back the muddy look, just dip the truck in cold water. When using it, make sure to keep it away from small children who might put parts in their mouths. Also, don't use very hot water as it could damage the truck. To maintain it, dry the truck thoroughly after each use to prevent rust. Store it in a dry place when not in use.
