Fat Brain Toys - Quack Stack

Buildable, stackable, puzzling fun for the bathtub is like water off a duck’s back with Quack Stack! Fit the colorful, uniquely-shaped duck pieces together atop the wobbly suction-cup feet and then pour water over the bright green spinner to see the wings go flap, flap, flap. It's endless inspiration for hours of open-ended fun in the tub!
