Classics do not disappoint.
In the original story of Dumbo, the titular elephant was helped by a robin named Red. Later, they meet an owl who tells them how Dumbo could possibly fly. Red and Dr. Hoot (the name the storyboarders gave the owl) were eventually changed to Timothy Q Mouse and the crows, respectively, but storyboards do exist of Red and Dr. Hoot. I'll send in a link that has them.
