Colorful preschool toy set with foam character headbands, a storybook, and a puzzle of a path to a castle.

"Design a collaborative role-playing toy set for preschool children to reduce egocentrism. The toy should include wearable masks or headbands with expressive faces representing different emotions and characters. It should also have a shared storybook or puzzle pieces that require two or more children to cooperate to solve. The toy encourages turn-taking, perspective sharing, and imaginative play. The colors should be bright and inviting, with large, easy-to-handle pieces." See more
