Telecreepers (or whatever they are called) can be a problem. So far they have teleported 3 enderminis and a creeper into my base. I am just glad creeper damage is off. Dire Wolves do about as much damage as the enderzoo mobs, from my experience. Their tactics are different then most mobs though. I think they are using the Vanilla wolve AI.Is there a secret to keeping them from spawning in otherwise safe areas?
I don't know if the creepers can telelport things onto halfslabs or not.
