Chilly Willy is a cartoon character, a diminutive anthropomorphic penguin living in Fairbanks, Alaska, although the species is native only to the southern hemisphere. He was created by Paul J. Smith for the Walter Lantz studio in 1953. The character soon became the second most popular Lantz/Universal character, behind Woody Woodpecker.
Chilly Willy was inspired, according to Scott MacGillivray's book Castle Films: A Hobbyist's Guide, by mystery writer Stuart Palmer. Palmer used the Lantz studio as a background for his novel Cold Poison, in which the cartoon star was a penguin character, and Lantz adopted the penguin idea for the screen. Chilly's diminutive figure was inspired by an image of Herbert Lee McCormick Jr., a small boy from Fairbanks. His name suggests the film actor Chill Wills.
Chilly Willy appeared in 50 theatrical short subjects produced by Lantz from 1953 to 1972, most of which involve his attempts to stay warm, and always meeting opposition from a dog named Smedley (voiced by Daws Butler in his Huckleberry Hound voice). There were times, however, when Chilly and Smedley got along, as they did in Vicious Viking and Fractured Friendship. Ironically, Chilly never referred to Smedley by name. Most times that Chilly was in opposition with Smedley, it wound up with the two of them being friends at the end. Chilly was more of a nuisance to Smedley than an enemy, often showing up where Smedley is working, usually for some mean employer.
In some episodes, Chilly Willy also deals with a hunter named Colonel Pot Shot (voiced by Daws Butler) whom Smedley has been shown to work for in some episodes. Pot Shot would give orders in a calm controlled voice, and then would explode in rage when he told Smedley what would happen should he fail in his objective. Also, two episodes had Chilly Willy outsmarting Wally Walrus when Chilly Willy comes across his fishing projects.
