Pink Elephants on Parade

"Pink Elephants on Parade" is a song and scene from the 1941 Disney animated feature film "Dumbo" in which Dumbo and Timothy Q. Mouse, having accidentally become intoxicated (through drinking water spiked with champagne), see pink elephants sing, dance, and play marching band instruments during an hallucination sequence. After the sequence, Dumbo and Timothy wake up, hungover, in a tree. It is at this point that they realize that Dumbo can fly.
The song was written by Oliver Wallace and Ned Washington and sung by Mel Blanc, Thurl Ravenscroft and The Sportsmen. The segment was directed by Norman Ferguson, laid out by Ken O'Connor and animated by Hicks Lokey, Frank Thomas, Karl Van Leuven, and Howard Swift.
The song is featured in the Disney live-action remake, directed by Tim Burton. The Pink Elephants themselves appear as human-made bubble sculptures which also come to life.
