Let kids add another fun challenge to their LEGO® Super Mario™ universe with this Boss Sumo Bro Topple Tower Expansion Set (71388). It features a tower that is rocked by LEGO® Mario™ and/or LEGO® Luigi™ (figures not included) stomping on the levers at its base. It can be built to varying heights, and a Super Star Block is revealed when Boss Sumo Bro is toppled. The set also includes a Crowber figure. (Note: the 71360 or 71387 Starter Course is required for interactive play.)
