Oswald the Rabbit and Peg Leg Pete take part in an air race across the Atlantic in The Ocean Hop (1927). A title card introduces ‘The Dark Horse.’ Oswald is hiding in a horse-like thing, his head sticking out of the horse’s neck, while the horse’s head bobs along, detached from the rest of the body. Animation by Ben Clopton.
The plane becomes human for a bit. He and Oswald tell Peg Leg what they think of him. This is all Hugh Harman’s work.
Ham Hamilton and Ub Iwerks animated on this cartoon, too. Read more about it HERE.
