The irresistibly cute Quackles floats, flashes, and quacks! Quackles is a fresh update on the classic rubber ducky that everyone associates with childhood. Features a sensor activated by water or touch which lights up the internal red flashing LEDs and makes Quackles quack. Comes with built-in long-lasting batteries that are not replaceable for safety reasons. Quackles measures about 3.5" diameter and 2.5" tall.
