Piggy

Piggy is an animated cartoon character, created by Rudolf Ising for Warner Bros' Merrie Melodies series. He was created shortly after Foxy, Ising's first creation and the initial star of the Merrie Melodies series. Piggy, like Foxy, was short lived, starring in only two cartoons, one less than Foxy's three cartoons. Like Foxy, Piggy was an imitation of Mickey Mouse, like most other cartoon characters of the day.

Both of Piggy's cartoons were released in 1931:
