 Two of Beatrix Potter's "little books", "The Tale of Pigling Bland" (1913) and "The Tale of Little Pig Robinson" (1930), feature the adventures of pigs dressed as people.Several animated cartoon series have included pigs as prominent characters.One of the earliest pigs in cartoon was the gluttonous "Piggy", who appeared in four Warner Brothers "Merrie Melodies" shorts between 1931 and 1937, most notably "Pigs Is Pigs", and was followed by Porky Pig, with similar habits.
