Using these GP BoonBoom Vehicles is easy. First, you'll need to assemble them. Once assembled, you can attach them to the BoonBoomger robo for some fun play. You can also use them in the BoonBoom changer. Just remember, these vehicles don't transform. For maintenance, keep them in a dry place and avoid rough handling. If you have any small parts, make sure to keep them away from young children to prevent choking hazards.
