Woohoo! Elmo now comes to life, just like the other Glo Pals that you know and love. Simply insert a Light Up Cube into Elmo and place him in liquid. He’ll instantly start to Glo, automatically! Each Pal typically lasts for 4+ weeks on average and each pack comes with four Pals inside. Remove Glo Pals Light-Up Cubes from liquid when not in use. Blow through small slots in the side of each Cube. Store in a dry location for longer battery life. Choking hazard. Small parts.
