Stack the rings on the wobbling base and let the deer dance and turn! It is quite a challenge to stack the rings on a wooden base that wobbles back and forth. But the cute deer encourages you to continue, and will celebrate with a small dance once the pyramid is finished. Every beautiful ring has a unique design inspired by the Fairy Garden collection. This tumbler stacker is designed to develop hand-eye coordination through pleasure and hands-on playing. Let the stacking adventure begin!
