Pied Piper Porky 1939

Directed by Robert Clampett

Porky Pig stars as the Pied Piper, who thinks he has taken care of all the mice. However, there is one rogue mouse that he is unable to catch. So he tries an old-fashioned mouse trap (a cat) and when the cat tries to fight, the result is the mouse wearing his fur (i.e. he killed him).
