I was thinking of a mob while I was playing multiplayer. I thoguht what if there was an enderman that was the size of your Default charecter Steve, and it was an enderman that could be tammed. And, if you throw block's in front of it, it will go to any nearby cave's and seek out the block. But, it cannot mine into the wall's it can only mine bare mineral's in the wall's. Tell me what you think :D - dddsss1
