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.
Credits go to Mojang for making it. I only made it in a papercraft figure.
