From an interview with The Paris Review.

RIP Eric Carle.

“My publisher and I fought bitterly over the stomachache scene in The Very Hungry Caterpillar. The caterpillar, you’ll recall, feasts on cake, ice cream, salami, pie, cheese, sausage, and so on. After this banquet I intended for him to proceed immediately to his metamorphosis, but my publisher insisted that he suffer an episode of nausea first—that some punishment follow his supposed overeating. This disgusted me. It ran entirely contrary to the message of the book. The caterpillar is, after all, very hungry, as sometimes we all are. He has recognized an immense appetite within him and has indulged it, and the experience transforms him, betters him. Including the punitive stomachache ruined the effect. It compromised the book.”
