Using this DX BoonBoom Monster Set is super easy. First, take out the BoonBoom Marine and Safari vehicles from the set. Then, combine them with the DX BoonBoomger Robo. You'll see it turn into the BoonBoomger Robo Monster. When playing, keep it away from small children who might put parts in their mouths. After playing, store the set in a dry place to avoid damage. If it gets dirty, you can use a soft cloth to clean it gently.
