How to use: First, take the included Hot Wheels Color Reveal vehicle and drive it over the ramp into the shark's mouth. Press the shark's head to make the water change color and show the car's deco. Pull up on the shark to let the car race down its insides. Tap the shark's tail to launch the car from the parking garage or into the cold water tank for a color shift. Run the car through the wash again to change its colors back. Notice: This playset is suitable for kids aged 3 and up. Keep small parts away from younger children to avoid choking hazards. Maintenance: After playing, use the handle to drain the excess water. You can fold the set in half for easy storage. If it gets dirty, you can use a damp cloth to wipe it clean.
