A week in the life of a caterpillar as depicted by the cut-out style artwork of Eric Carle. The caterpillar emerges from its egg and eats its way through a huge amount of food on each day of the week as it journeys to transform itself into a butterfly. Told in Carle’s ingenious illustrative style and complete with die-cut pages and actual holes indicating where the caterpillar ate, Carle’s book has delighted children for almost 40 years.
