As of the latest don't starve update a new mob was introduced called the Krumpus, apparently he appears when you hunt too many animals but I don't quite understand how this works. From what I understand, you get several points of "Niceness" when you start, and they decrease as you do naughty things such as hunt animals.
How does this work? Do you get a certain number of naughty points every day or must you perform some "nice" acts in order to raise the amount by which you can hunt? I find this to be a very large impediment while searching for food, I am restricted to purely carrots and berries and seeds, but without meat you can't really survive for that long
