He builds a cocoon around himself and stays inside of it for two weeks, after which he nibbles a hole and pushes his way out, emerging as a large, multi-colored butterfly. However, he is no longer little and hungry he is now a "big and fat" caterpillar. To recover from Saturday's stomachache, the very hungry caterpillar eats one green leaf on Sunday, and feels much better. That night, he gets a stomachache from overeating. On Saturday, he feasts, eating a piece of chocolate cake, a strawberry ice cream cone, a pickle, a slice of Swiss cheese, a slice of salami, a lollipop, a piece of cherry pie, a sausage, a cupcake and a slice of watermelon. Each day, however, the caterpillar is still hungry. For the following five days, Monday through Friday, the very hungry caterpillar eats through an increasing quantity of fruit: one apple on Monday, two pears on Tuesday, three plums on Wednesday, four strawberries on Thursday, and five oranges on Friday. On an early Sunday morning, "a tiny and very hungry caterpillar" hatches from his egg and searches for something to eat.

It has been lauded as "one of the greatest childhood classics of all time," and has won praise for its iconic art style, featuring collage artwork and holes in the pages where the caterpillar "ate" through, that was innovative for its time. Since its publication it has sold more than 50 million copies, been translated into more than 60 languages, won various awards, and been adapted for television. The plot follows a very hungry caterpillar that eats a variety of foods before pupating and emerging as a butterfly, and incorporates elements that contribute to juvenile education, such as counting, the days of the week, food, and a butterfly’s life cycle. The Very Hungry Caterpillar is a 1969 children's picture book designed, illustrated, and written by American children's author and illustrator Eric Carle.
