Xerxes, size was never a fantastical thing with me, because giants or people taller than 8 feet tall have existed in the past. Like, Galioath( if you believe the Bible). So I was never thrown off by his size. Also the giant guy with the swords never bothered me because skin and tissue will grow around things. Cut the arms place the swords inside sow up the wound around the swords, and eventually skin and tissue will form around the object. It is like the brain, when some foriegn object gets in your brain say like a bullett or nail, your brain tissue will grow to the object and form recepters to it ( if you survive the accident). It doesn't recognize it as anything other than tissue so it grows to it. But I have never seen any record of a goat acting like that goat did. It was completely wrong.
