This is a popular picture book toy based on the "Kuishinbo Rule" series. The toy features a house with round and square holes, allowing children to play with shape-matching (shape-sorting) puzzles. Small stuffed animal figures (pig, chicken, etc.) are included and can be placed inside the house, or children can play with finger puppets. The fabric is designed to stimulate a baby's senses, with features like crinkling sounds when touched. Please enjoy playing with the dolls while reading the picture book with your child.
