With the Poppin' Play Piano, preschoolers press piano keys to explore numbers, colors, & more. Whenever kids press keys, colorful balls pop up in clear tubes. There are four play & learning modes. In Number Mode, when kids press a key, the piano will sing the number on each key in a different pitch. In Color Mode, children play the piano to hear the color names of each key sung in a different pitch. In Free Play Mode, kids press a key to select an instrument sound, then play all the keys to hear that sound. (To change the sound, slide the mode switch back & forth.) In Song Mode, pressing a key will begin a song that kids can play along with.
