Learn about all the creatures that live in the forest with this fun puzzle and recognize their shapes and unique sounds. When you lift a piece, you'll hear a matching sound. This 7-piece puzzle of animals, leaves, mushrooms, promotes hand-eye coordination and stimulates your child's vocabulary. The puzzle contains sensors that are activated by light - use in bright light for best results. Make sure the switch is on to activate the sound function. The sensors can be accidentally activated by direct sunlight, so the puzzle should always be turned off when not in use. (Batteries (2 x AAA) not included.)
