Using this PAW Patrol Rescue Wheels Chase & Marshall Metallic Team Pack is super easy. First, clip Chase and Marshall into their driver's seats of the monster trucks. Then, when you're ready for action, load one of the two projectiles into the projectile launcher. Just push the button on the launcher, and the projectile will fire. Remember to keep the projectiles away from your eyes. When you're done playing, store the toys in a dry place to prevent damage. If the trucks get dirty, you can use a soft, damp cloth to clean them. This toy is for kids aged 3 and up, so make sure younger kids don't play with it without adult supervision.
