Sounds like a great idea! We’ve taken peg puzzles to the next level with our new Wooden Sound Puzzles. Play musical notes, listen to letter and number sounds, imitate animal and vehicle sounds, and more! Realistic sounds are played when the puzzle pieces are properly placed on the board. It’s a fun and unique way to reinforce cause-and-effect, early vocabulary and matching skills. Ages 2+. 9” x 12” each.
