Using the Hot Wheels Monster Trucks Arena Smashers Bone Shaker Ultimate Crush Yard playset is super easy and fun. First, take out the 1:64 scale Hot Wheels Monster Trucks Bone Shaker and the 3 crushable cars from the set. Place the cars at the five smash spots on the playset. You can drive the Bone Shaker up the tower of crushed cars and then smash it down for an exciting experience. The moving and shaking base will make you feel like you're really in a Monster Truck arena. To expand the fun, you can connect this set to other Hot Wheels Monster Trucks Arena Smashers sets (remember, additional sets are sold separately). When it comes to care, keep the set in a dry place away from sharp objects to avoid damaging the cars and the playset. If it gets dirty, you can use a soft, dry cloth to clean it. Always make sure to play with the set on a flat surface so the base can move and shake properly. Have a great time playing with your new playset!
