Pigmasks are the members of the Pig Army that wear pig-like masks over their faces and greet each other with squealing noises. They may sometimes look ridiculous or dull-witted, but higher-ranking Pigmasks are involved in more vile and complex schemes. They don't mess around. Some Pigmasks are harmless NPCs that you can talk to, but on many occasions you'll have to do battle with them.
