Using the Rubble's Aqua Hammerhead Rescue Vehicle is super easy. First, place Rubble in the vehicle cockpit and then slide the canopy shut. This will engage the wing and dorsal fin, and transform the vehicle into rescue mode. When there's an emergency, just speed off to the rescue. Use the articulated drill tail and Hammerhead blade to get rid of any obstacles in your way. As for maintenance, keep it away from sharp objects that could scratch the vehicle. Also, avoid exposing it to extreme heat or cold. If it gets dirty, you can use a soft, damp cloth to gently wipe it clean. Make sure to dry it thoroughly before storing. And remember, the Aqua Pups figures and other toy vehicles are sold separately, so you can collect them all for more fun.
