Sing along with favorite childhood characters like Humpty Dumpty and Jack and Jill with this unique wooden peg song puzzle! Match the six illustrated wooden puzzle pieces to the pictures in the beautifully carved wooden puzzle board to hear six different nursery rhymes (Humpty Dumpty, Baa Baa Black Sheep, Hey Diddle Diddle, Mary Had a Little Lamb, Twinkle Twinkle Little Star, and Jack and Jill). Plastic pegs make it easy for small hands to grasp and manipulate the pieces. Lyrics are included on the puzzle so kids can sing along as they complete the puzzle! TIP: Puzzle has light-activated sensors; for best results, expose the sensor by removing a piece in a brightly lit room, then make the sound play by replacing the piece in the board; 2 AAA batteries required, not included
