You must not think that it was wrong in her to care so much about eating. She was only doing what is expected of a Polyphemus Caterpillar, and you would have to do the same if you were a Polyphemus Caterpillar. When she was ten days old she had to weigh ten times as much as she did the morning that she was hatched. When she was twenty days old she had to weigh sixty times as much; when she was a month old she had to weigh six hundred and twenty times as much; and when she was fifty days old she had to weigh four thousand times as much as she did at hatching. Every bit of this flesh was made of the food she ate. That is why eating was so important, you know, and if she had chosen to eat the wrong kind of leaves just because they tasted good, she would never have become such a fine great Caterpillar as she did. She might better not eat anything than to eat the wrong sort, and she knew it.
