Pig-headed killers are actually more common in horror than you might initially think. In the Saw franchise, Jigsaw's followers wore terrifying pig masks. The murderous farmer in 1980's Motel Hell wore a decapitated pig head. And in the AHS universe, Piggy Man is a popular urban legend that claims you can summon the creature by saying "Here, piggy piggy pig" in a mirror three times.
