How to use: First, place your 1:64 scale Monster Jam truck in the launcher. Slam the launcher firmly and at the right angle to send the truck up the ramp. Try to hit the trick bar to perform a backflip onto the landing ramp. To reveal Max - D, make sure the truck hits the trick bar at the top of the playset. Note: This playset is for kids aged 3 and up. Keep small parts away from very young children to avoid choking hazards. Maintenance: Wipe the playset with a clean, dry cloth to keep it looking new. Don't use harsh chemicals on the truck or the playset.
