Pig

Behavior
Attacking pigs will yield one meat.

If you feed a pig berries, flowers or carrots, they will drop 1 manure in a few seconds.

Feeding a pig any meat item (indiscriminately) will cause the pig to follow you. Feeding a pig meats will cause them to turn into werepigs. 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, yeilding morsels, as rabbits do not run from pigs.

Pigs can be killed by all combat monsters, and will attack spiders and tenticles 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 death, following pigs will revert back to wild pigs.
