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. 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.

History
Minecraft user Miclee made up the idea for Pigmen. He was given the Bacon Cape as a reward. Afterwards, when Notch was asked for personal capes by other users, the Bacon Cape was taken away from Miclee to prevent further commotion.

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.

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.

Trivia

 * Pigmen have the same shape as Zombie Pigmen, Zombies, Humans, and Players.
 * Because villagers have already been confirmed, it is very unlikely pigmen will be added to villages.
 * There is much dispute about Pigmen being promised as an addition to the game in a future update. This claim is completely false. There is no evidence on any website that Notch, _Jeb, or any other member of the Mojang team has said anything about pigmen being a guaranteed as an addition.
