Using this PAW Patrol Marshall's Dolphin Rescue Vehicle is easy. First, place Marshall in the vehicle cockpit and slide the canopy shut to transform it into rescue mode. When there's a pretend 'trouble' situation, load the projectile into the launcher and press the button to launch. For more fun, collect other Aqua Pups figures and toy vehicles (sold separately). As for maintenance, keep the vehicle clean by using a dry cloth to wipe it. Avoid getting water inside the launcher to prevent damage. Also, make sure small parts like the projectiles are kept away from very young children to avoid choking hazards. Have a great time playing with this toy!
