Uncle Walt then dwells on how anything is possible in the animated medium during “The Plausible Impossible” (1956, 51:07). Specially created animation of Mickey Mouse and Donald Duck is used to show how the laws of physics can be ignored. He explains animation should still at least have roots in reality, which links to a lengthy clip of the nature-based Bambi. More clips of Fantasia are used to show how music can apply to a variety of animated sequences, in a mix-and-match of segments from the film to different scores. The most exciting highlight is a deleted scene from Snow White in rough pencil form, entailing the musical number “Music in Your Soup”, as Mr. Disney explains the editing process.
