Title: The Very Hungry Caterpillar (Picture Puffin) by Eric Carle

Plot Summary: "The Very Hungry Caterpillar" is a children's picture book written and illustrated by Eric Carle. The story begins with a small caterpillar emerging from an egg on a Sunday morning. The caterpillar is very hungry and starts eating everything in sight, including various fruits, sweets, and junk food. Each day, the caterpillar consumes more food: one apple on Monday, two pears on Tuesday, three plums on Wednesday, four strawberries on Thursday, and five oranges on Friday. On Saturday, the caterpillar eats an enormous amount of food, including chocolate cake, ice cream, and other treats, which ultimately leads to a stomachache.

The next morning, it is Sunday again, and the caterpillar eats a single green leaf, which makes him feel much better. After this change in diet, the caterpillar is no longer hungry and has grown significantly. He then builds a cocoon around himself and sleeps inside for two weeks. Finally, the caterpillar emerges as a beautiful butterfly with large, colorful wings.
