This 8-piece wooden sound puzzle features a sturdy wooden board with light-activated sensors that play 8 realistic animal sounds. Each wooden peg puzzle piece has a full-color matching picture underneath. For optimal performance, remove a piece in a well-lit room to expose the sensor, then replace the piece to trigger the sound. The auditory feedback supports independent play for children. The puzzle requires 2 AAA batteries (not included). Designed for toddlers and preschoolers ages 2 to 5, it provides hands-on, screen-free play.
