Based on a traditional memory game, this book is a cumulative counting book which has a strong rhyming text and detailed illustrations. Right-hand pages show the objects from one model train to ten soft toys hidden in a scene. Left-hand pages build into a picture list of miniature objects where two naughty rabbits play hide-and-seek. The book culminates with all the objects spilling out of the bag again to make a seemingly endless game. Ian Penney is the illustrator of "A Shop Full of Kittens" and "Under the Sun and Over the Moon".
