Pigman

A Pigman is a Pig in a humanoid form. Although not implemented, their skin can be found within the game files, and their counterpart, Zombie Pigmen, have been part of The Nether since the Minecraft Alpha 1.2.0 Halloween Update. Notch mentioned April 25th, 2011 that he might add Pigmen as NPC Villages' townspeople. In Beta 1.9 Pre-releases, a different Villager mob was introduced, making Pigmen as Village NPCs less likely. The skin for a Pigman can be seen on the right. It has the same dimensions as the player, and has no coding present within the game that spawns them.

Trivia
Pigman can only be spawned in a mod or hacked in by CheatCoderz (My website)
 * Pigmen have the same shape as Zombie Pigmen, Zombies, Humans, and Players.
 * Minecraft user Miclee made up the idea for Pigmen. He was given the Bacon Cloak as a reward. Afterwards, when Notch was asked for personal capes by other users, the Bacon Cloak was taken away from Miclee to prevent further commotion.
 * Regular pig models were changed in Beta 1.8 to have a protruding snout. Whether this will be applied to Pigmen or Zombie Pigmen in the future is unknown, although possibly unlikely due to the fact stated above of sharing the same shape as other entities.
