Donald Duck (film series) in the context of "Private Pluto"

Pete (also named Peg Leg Pete, Bad Pete, and Black Pete, among other names) is a cartoon character created by Walt Disney and Ub Iwerks of The Walt Disney Company. Pete is traditionally depicted as the villainous arch-nemesis of Mickey Mouse, and was made notorious for his repeated attempts to kidnap Minnie Mouse. Pete is the oldest continuing Disney character, having debuted in the cartoon Alice Solves the Puzzle in 1925. He originally bore the appearance of an anthropomorphic bear, but with the advent of Mickey in 1928, he was defined as a cat.

Pete appeared in 67 animated short films between 1925 and 1954, having been featured in the Alice Comedies and Oswald the Lucky Rabbit cartoons, and later in the Mickey Mouse, Donald Duck, and Goofy cartoons. During World War II, he played the long-suffering sergeant trying to make a soldier out of Donald Duck in a series of animated shorts.

Don Donald is a 1937 American animated short film produced by Walt Disney Productions and released by United Artists. The cartoon follows Donald Duck attempting to woo a female Mexican duck named Donna. It was directed by Ben Sharpsteen and features music by Paul J. Smith which was adapted from the Mexican folk songs "Cielito Lindo" and "Jarabe Tapatío". Clarence Nash voiced both Donald and Donna.

Although billed at the time as another Mickey Mouse cartoon, explaining the face of Mickey Mouse at the beginning of the original release, the film is actually the first installment of the Donald Duck series, and is the first to feature Donald as the primary starring character. The film also introduces a love interest for Donald.
