After all of the credits Thumbelina runs across the screen and "a DON BLUTH presentation" follows her. A few seconds later Prince Cornelius on his bumblebee fly across the words and they vanish.
The voice actors are credited twice. First under "Voices in Order of Performance" and again under "The Actors (In Alphabetical Order".
The end credits are on a book page and there are pictures that change every few minutes starting with the beetle and ending with Hero the dog.
