Werewolves

[Bumble]

Werewolves should spawn during full moons in low wilderness level areas. They should mess up your stuff, kill livestock, go after players, and things. You'd be able to kill them for some type of goodies. You'd probably have to introduce wolves first though.

I think they are already implemented, haven't bothered looking for one yet though.
