Abstract
A playset includes a series of pieces sequentially stackable on a hollow base and interconnected by a flexible tether. One end of the tether is secured to an end piece and the other, free end passes through the base and is connected to a tab. When a child pulls the tab the pieces are stacked on the base to form a tower. A plunger mounted on the outside of the base is depressable to move a lever mounted in the base upwardly to topple the stacked pieces.
