Watch the caterpillar transform into a butterfly in this unique novelty book where the pages fold out to create one big final image. A tiny caterpillar has hatched from its egg and is looking for something to eat. Turn the pages of this unique format to see the caterpillar grow and grow, change into a golden chrysalis, and emerge at last as a most amazing butterfly. The pages fold out into a big buddleia bush with all different kinds of insects hidden among the leaves, while the book's central flap conceals additional facts and information about this fascinating life-cycle.
