Mr. Pig

Mr. Pig is a character who first appears in "Apple Thief." In this episode, he is referred to simply as "Pig" until later in the episode when Tree Trunks calls him "Mr. Pig". In his debut, Jaybird orders Finn, Jake, and Tree Trunks to be executed by having the Pig eat them alive. Even though he worked with villains, Pig appears to have a nice personality.
