Got SOOO annoying over by the area on the island where the west coast and the southern jungle meet. They travel in packs most of the time. The worst place to encounter at is the rocky areas. If your character is getting damaged and you don't know what it is, look down and around your legs, there possibly will be a pack of four or less. They run off when they are damaged to where they are at 30 health or less, then they come back, so you have to pay attention to where they run off to. You don't want to encounter a group of them if you're already at low health, trust me.
