When children press a key on the piano, they not only hear a sound, they see a ball pop up! The clear, non-removable dome guides the colorful balls into 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. Press the soft, squishy Mirari button to hear the signature Mirari giggle! Pop! Pop! Piano measures 9" x 11.5" x 5.5" and has a wood top on the base for a modern, rich look and feel.
