Using these Monster Jam Mini Marvel trucks is easy. Just grab a truck and start pushing it around on a flat surface to make it roll. You can create your own Monster Jam tracks with books, blocks, or other toys to let the trucks do stunts and jumps. When playing, make sure to keep the trucks away from small children who might put them in their mouths as they are not suitable for very young kids. To keep the trucks in good condition, wipe them with a dry cloth if they get dirty. Don't use any harsh chemicals or cleaners. Store them in a dry place when not in use to prevent any damage. Have a blast with these awesome trucks and let your imagination run wild!
