Mosswine

Wild pigs covered in moss and fungus. Sometimes you will even find mushrooms growing on them. Their meat is known as a delicacy. Though normally docile, they will charge you if angered!
A pig-like Herbivore that roams looking for its favorite food, mushrooms. It lives in the Jungle and the Great Forest. It charges back when attacked, but its health is low and its attacks are simple, so it is not dangerous. When killed, it has a high chance of yielding Mushrooms when carved.
