Werepig

Werepigs are Pigs that have gone feral and will start attacking each other as well as the player. Werepigs will stop to eat any Food on the ground, and can produce Manure if they eat Vegetables or Fruits. They will also eat raw Mandrakes, as opposed to Pigs.

Spawning


Feeding a pig 4 pieces of Monster meat will cause it to transform into a werepig. A Werepig will also spawn when a pig is outside during a fullmoon.

Hostility and combat


Werepigs are hostile, and deal a fair amount of damage. They can be taken down with 4 hits from the spear, and subsequently drop normal meat.

Werepigs will attack other pigs that are not changed. They will also attack Spider Nests and spiders. Beefalos, Tallbirds, Bees and anything else that is in the area that isn't a werepig. Although sometimes there will be occurrences of Werepigs attacking each other as well as the player.

They are more than capable of keeping up with the player and will chase  until they are dispatched When the moon changes they will change back to a regular pig.

If the player attacks a Werepig while other Pigs are nearby, they will also turn hostile against the player.

They are immune to the Sleep Darts and Pan Flute.

Cycle
As the full moon rises the pigs change to werepig and will remain in that state for the day. On the next day and possibly during that night they turn back. Once in normal pig form they go to sleep muttering about home. When they wake they run back to their houses and return to normal pig life.

Sometimes half the pigs will turn one night and the rest the next night. Assuming they survive each other's company.

Followers/Entourage
Be aware of the moon phases. If a full moon is coming up it may be best to lose the pigs before nightfall.
