Using this PAW Patrol Rex's dino rescue vehicle toy is easy. When you want to start a mission, simply clip Rex's feet into the driver's seat. Then, you can roll the vehicle around using its real - working wheels and use the movable ramp as needed. It's a great way to recreate scenes from the show and come up with your own adventures. As for maintenance, keep it away from sharp objects to avoid scratches. You can clean it with a damp cloth if it gets dirty. This toy is made for kids aged 3 and up, so make sure younger children don't play with it to prevent any choking hazards. And remember, the other PAW toy figures and rescue vehicles are sold separately, so you can collect them all to have more fun!
