How to use: First, assemble the track set according to the instructions. It's easy to do! Then, place one of the 3 die - cast cars on the pull - back elastic launcher. Pull the car back to charge the launcher, and then let go to launch it down the track. Try to make it jump through the dino's jaws. You can also use it with other Teamsterz playsets and vehicles for more fun. Note: Keep small parts away from children under 3 to avoid choking hazards. When playing, make sure the track is on a flat surface. Maintenance: If the cars or track get dirty, you can use a soft, dry cloth to wipe them clean. Don't submerge the die - cast cars in water as it may damage them.
