Pig

Pigs are a non-aggressive mob that live in pig houses. Attacking a pig will aggro him and all nearby pigs. Killed pigs drop 1 meat and respawn the next morning from their houses. If you feed a pig uncooked Berries, flowers, or cooked Carrots, they will drop 1 Manure (and all fed items will be dropped upon death). Feeding a pig any meat item (indiscriminately) will cause the pig to follow you. Feeding pigs 3 times monster meat will cause them to turn into Werepigs.

You can attack following pigs by CTRL+left clicking on them. (They will attack back!)

Behavior
Following pigs can be used to assist in woodcutting or combat. This is initiated by swinging your axe at a tree, or clicking to attack an animal. While a swing must be made to the tree before the pig assists, no swing must be made to an animal. Simply clicking, then retreating causes the pig to initiate combat. This can be used to attack rabbits, yielding morsels, although rabbits do run from pigs now. If they kill beefalos, they will try and grab the meat, letting beefalos kill pigs is another way to get meat.

Pigs can be killed by all combat monsters, and will attack spiders and tentacles once they see them. Following pigs will also attack any animal that turns aggressive toward you, including other pigs.

Following pigs will not retreat to their houses at night. This can be problematic, as pigs fear the dark. Following pigs that are not nearby a light source at the first sign of darkness will run around their current area until they are collected again in daylight.

Upon player´s death, following pigs will revert back to wild pigs. If you do not continually feed them meat, they will say "Home Home" and run home.

At full moon they turn to werepigs and attack your character on sight. Appears that they may fall asleep after being werepigs (see image to right.)

Pig King
The King of Pigs. Can by found next to several pig houses generated at world creation. If you feed him with any kind of meat (not monster meat), cooked or raw, he will give you 1 Gold Nugget. Giving him gravedigger items (except Amulet) will yield 3-8 Gold Nuggets.
