12 months & up. Press a key on the piano, hear the sound, and watch the stars pop up! The clear arch guides the stars into different pipes each time so when another note is played the star pops up again. Infants and toddlers love watching the flying stars inside the clear dome. When the keys are pressed, hear piano tones or flip the switch to hear fun sound effects. Remove the arch to allow the 1-1/4" stars to pop out on the floor and encourage your child to crawl after them. Piano measures 11" x 5-3/4" with clear arch attached.
