Glo Pals are liquid-activated, meaning they only work when water is in the bath tub. Draw a bath, drop the Pals in, and watch them light up! When it's time to get out, drain the tub. The Pals turn off automatically, signaling that bathtime is over.
Each Pal has a face and a different "personality" and when placed in liquid, the faces will project onto the surroundings of the tub!
