How to use: First, place the oversized Skelesaurus and the 1:64 scale Bone Shaker on the starting point of the track. Then, use the power switch to release the two vehicles. Watch them speed down the hill and towards the massive loop. The randomizer will decide the winner of the race. Note: Keep small parts away from children under 3 to avoid choking hazards. When not in use, store the track set and cars in a dry place to prevent damage. If the cars or track get dirty, you can use a soft, dry cloth to clean them gently.
