Hunted as a food source, these creatures are preyed upon by both hunter and monster alike. Usually timid, in packs they will defend themselves with surprising strength.
A Herbivore that lives in places like the Forest and Hills and the Jungle. It is docile, but it may attack if you go after its young. It is a good monster for getting Raw Meat, the ingredient for the essential Well-Done Steak.
