When you first encounter it it will be peaceful feed it Plant species Z seed and or Chitin. Once you do this it jump around then crest a webbed mound where he or she will flash red or green for a game red light or green light. When it is green run up before it turns red. If not just crouch just to be safe, then wait for it to be green again. Then rinse and repeat if necessary. If you mess up it will attack you for like 2 seconds then just wait for it to mound up again.
