A well-illustrated picture storybook about a mouse who discovers a cardboard box and makes it into a house. A frog, a rabbit, a hen and a duck come along and all manage to fit in together. But then a huge bear turns up and spoils the box by sitting on it. What a good book for 2-4 year-olds! Each animal is clearly described and the listening/looking child can learn about size and shape as the bear is much bigger than all the others. And the word 'down' (not an easy abstract concept for the young child) can be understood as the bear lowers its bulky body 'down' onto the cardboard box.
