Not surprisingly, he ends up with a stomach ache. Fortunately, a serving of one green leaf helps. The now very fat caterpillar builds a cocoon. After staying in it for two weeks, he nibbles a hole in the cocoon and emerges a beautiful butterfly. What adds immensely to the book's appeal is its design.
Every page has a hole in it where the caterpillar eats through the food.
The pages for the first five days are different sizes, corresponding with the number of pieces of food the caterpillar eats. The page for the day the caterpillar eats one apple is very small, a little bigger for the day it eats two pears, and full size for the day it eats five oranges. The Very Hungry Caterpillar was originally published in 1969. I think in my books I honor my father by writing about small living things. And in a way, I recapture those happy times.
