Since its introduction in 1969, the Change-a-Tune Piano has been a childhood favorite. This Fisher Price classic is back, and has been upgraded for a whole new generation to enjoy! Turn the dial on the side of the piano and tap the keys to play along with one of the three classic tunes, "Pop! Goes the Weasel," "This Old Man," or "The Muffin Man". The new reissue of the classic toy requires 3x AA batteries to operate, included.
