Experience the adventures of the Hot Wheels City Mega Car Wash with hot and cold water tanks that activate color-changing features in an amazing playset. The set comes with 1 Hot Wheels Color Shifters car that changes color in cold water and then changes back in warm water. It's like getting 2 cars in 1! Kids spray their Color Shifters car with cold water from the blue tank to reveal a design and then spray again with warm water from the red tank to change it back. Park 3 Color Shifters vehicles in the middle parking spots and change the deco of 3 additional cars simultaneously! (Additional vehicles sold separately.) A tray at the base of the set catches excess water as vehicles move through the wash for mess-free play. The set features many track play functions that don't require water, such as moving gates, foam roller, and adjustable gas hose. The Hot Wheels City Mega Car Wash is a great gift for kids 4 years and older and connects to other Hot Wheels sets and tracks so they can create an urban landscape with their own design.
