Big Bird is here to bring BIG time fun! Big Bird now comes to life, just like the other Glo Pals that you know and love. Simply insert a Light-Up Cube into Big Bird and place him in liquid. He'll instantly start to Glo, bringing Sunny Days to playtime! Each Pal typically lasts for 4+ weeks on average. 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.
