Beaver Building Fun™ is a crazy game where kids use the plastic construction-worker beaver figures to build up a tall building, and then try not to be the one to knock it down! Each level stacks higher and higher as it becomes more and more wobbly. If it tumbles down, that player is out and the player who forced them to stack the last card wins! There's even an advanced level where players face extra challenges like stacking with both hands or standing on one foot!​
