Mutant pig only appears in ANGRY BIRDS:HALLOWN BIRDS. He was a normal pig but King Pig, Mustache Pig, and Dr. Pigs put him in a teleporter since they needed a more moreful pig than normal, but something happened and he got a extra eye. He became bigger than King Piggie and big pigs. He crushed a stupid Doctor Pig that walked up to the teleporter. King Pig started making a bunch of them but they ended up with three ears, four mouths, and extra eyebrows. They turned into failed mutant pigs. (See future blog post ALL NEW PIGS: failed mutant pigs.) He got to get his own spear (most piggies have no weapons minus army pigs) and poisoned sword. He was a boss, he got half-killed but he escaped and got to be a colonel in the pig army and got to lead a bunch of army pigs and helmet pigs.
