Droopy is an animated character from the Golden Age of American Animation: an anthropomorphic dog with a droopy face, hence the name Droopy. He was created in 1943 by Tex Avery for theatrical cartoon shorts produced by the Metro-Goldwyn-Mayer cartoon studio. Essentially the polar opposite of Avery's other MGM character, the loud and wacky Screwy Squirrel, Droopy moves slowly and lethargically, speaks in a jowly monotone voice, and—though hardly an imposing character—is shrewd enough to outwit his enemies. When finally roused to anger, often by a bad guy laughing heartily at him, Droopy is capable of beating adversaries many times his size with a comical thrashing ("You know what? That makes me mad!").
In 1980, Filmation produced a series of lower-budget Droopy shorts for television as part of its Tom and Jerry TV series The Tom and Jerry Comedy Show. In the 1990s Hanna-Barbera series Tom & Jerry Kids, Droopy had a young son named Dripple (voiced by Charlie Adler), an older version of the infant we see in Homesteader Droopy. The mild success of the show provided perhaps the most Droopy merchandise: plush toys, gummy snacks, figurines, etc. In 1993, Tom & Jerry Kids had a spin-off series, Droopy, Master Detective, which cast Droopy and son as film noir style detectives. Droopy also had cameos in two theatrical features: as an elevator operator in Who Framed Roger Rabbit(where he was voiced by the film's animation director Richard Williams), and in Tom and Jerry: The Movie. Droopy also had cameos in all three subsequent Disney-produced Roger Rabbit shorts, Tummy Trouble (again he's an elevator operator), Roller Coaster Rabbit (he plays a bad guy dressed as Snidely Whiplash), and Trail Mix-Up (he plays a scuba diver). Droopy also appears in the 2006 cartoon series Tom and Jerry Tales, and has appeared in almost every Tom and Jerry direct-to-video movie, beginning with Tom and Jerry: The Magic Ring.
