Our latest solar dancing penguin is powered by the sun or any ambient light! Simply put the penguin in the sun (or under ambient light) and watch it dance and sway back and forth on its own. No batteries needed for this penguin to do the hula waddle. This 4" tall solar dancing penguin is a perfect choice for a desk, windowsill, dresser, table or shelf. Home, school or office this is a wonderful and unique penguin to have. Makes a great gift. Obviously, no batteries needed.  Chocking hazard and not for children 3 or under.
