Eight-piece wooden sound puzzle with sturdy wooden puzzle board. Each happy farm animal "sounds off" in its own voice when its animal puzzle piece is placed correctly in its place! Children will enjoy hearing all eight sounds and looking at the full-color, matching pictures under the pieces, while developing matching and listening skills with this captivating multisensory puzzle. 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.) Requires 2 AAA batteries (not included). For ages 2+ years.
