Watch it wobble around and around! Three uniquely textured tracks slide onto the tower in any order you want. Drop one of the balls onto the top and send it rolling with a light clatter. Wonder abounds as its weight tips the tower this way and that atop the wobbly base! Then, once it's time to go, all the balls can be stored inside the tower for easy clean-up. Classic ball-run fun becomes a topsy-turvy delight with Wobble Run!
