Minecraft (Pocket Edition)
Perhaps the only thing uglier than a Zombie is a Zombie Pigman. Zombie Pigmen are not found throughout Minecraft, and only briefly appear in the overworld when a Nether Reactor is activated. They are a Hostile Mob creature. They can be killed with any block, though most efficiently with a powerful Sword.
Usage / Purpose
Despite their nasty appearance, Zombie Pigmen are a necessary problem created when you open a Nether Reactor and reap the benefits of what it spits out.
Drops / Yields
When killed they produce Gold Ingot. Not bad for such a horrific creature.
Zombies Pigmen are available in both Survival Mode (as a naturally spawning creature), or in Creative Mode as a Spawn Zombie Pigman Egg.
Zombies Pigmen carry a Gold Sword. They are also immune to fire.
