This toy supports fine motor development by requiring precise finger movements to open the various locks on the board. It also encourages patience, as some locks may initially challenge younger children, helping them build resilience through repeated attempts. The green door features a movable switch displaying "Attention" or "Hello," providing an opportunity to discuss safety and stranger awareness. The set includes multiple functional locks, a working clock with a light, and a hidden cat behind each door for added engagement. A built-in handle allows for easy portability.
