Using this playset is super easy! First, take the die - cast colour change car and place it on the slam launcher. Give it a good push to send it up the track, through the skeleton, and into the skull. When the car is in the skull, fill a container with warm water and put the car in. Wait a bit, and you'll see it change colour. To get it back to its original colour, drive the car down the mountain and into a container filled with cold water. For maintenance, keep the playset away from sharp objects to avoid scratches. After playing, dry the car and the playset to prevent rust. Also, make sure small children don't put the car in their mouths. This playset is designed for kids aged 3 and up, so always supervise younger kids during playtime.
