Piggy is the name of two animated cartoon characters in the Merrie Melodies series of films distributed by Warner Bros. The first character was a fat, black pig wearing a pair of shorts with two large buttons in the front, and his first film was You Don't Know What You're Doin'! Piggy's name came from one of two brothers who were childhood classmates of Freleng's, nicknamed "Porky" and "Piggy".
