Fat Brain Toys - Quack Stack

Buildable & stackable fat brain toys for the bathtub. Look just 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!
