How to use: Simply hold the truck and let your imagination run wild. You can push it on flat surfaces to make it move around and act out Monster Truck adventures. Notice: These trucks are for kids 3 years old and up, so make sure younger kids don't put small parts in their mouths. Also, be careful when playing to avoid dropping the trucks on hard floors which might damage them. Maintenance: Keep the trucks clean by using a soft cloth to wipe off dust. Store them in a dry place to prevent rusting. Have a blast with your Hot Wheels Monster Trucks!
