To use this SG BoonBoom vehicle set, simply take out the vehicles and start playing. You can combine them with the DX BoonBoom Changer (sold separately) for more fun. Remember that the shovel and dozer won't transform like the DX models. When you're done playing, store the vehicles in a dry place to prevent damage. Keep them away from sharp objects to avoid scratches. Regularly check for any loose parts and make sure they're in good condition. Have a great time with your SG BoonBoom vehicles!
