When children correctly place a piece into the board, they hear realistic sounds of the depicted object. The puzzle includes eight different objects and sounds, with a coloured picture corresponding to each theme under the wooden pieces. The pieces have an ideal size for small children's hands and the entire puzzle measures approximately 22.2 × 29.8 × 2.5 cm. (TIP: The puzzle uses light sensors – for best function uncover the sensor by removing a piece in a well-lit room and then activate the sound by placing it back correctly on the board.) Discover and correctly place the pieces, reveal the sounds – when a piece is removed, a coloured illustration appears. When returned correctly, the corresponding sound plays, which supports fun learning. Skills development – Supports fine motor skills, hand–eye coordination, sound recognition, and problem-solving. Encourages imagination and early learning through sound, shapes, and visual stimuli. (Requires 2× AAA batteries, not included.)
