When children press a key on the piano, they not only hear a sound, they see a star pop up! The clear dome guides the shooting stars onto a different pipe so when another note is played, they’ll pop some more! Flip the switch to go from piano tones to hearing fun sound effects when the keys are pressed. Measures 9" x 11" x 5 3⁄4". Requires 3 “AA“ batteries, included. Ages 12 months and up.
