Ghast

Ghasts are twisted creatures that serve Herobrine. Their squid like feature enables them to fly. Do NOT be fooled by their calm appearance for they are deadly! Legend has it that the Ghast are formed from all the cats the horrible Herobrie has slain. Some others beleive that they form from ghosts of all creatures that never live in peace and hunt all that disturbs them in their slumber. But if you're one of the normal(ish) people then you will beleive that they are strange floating squids that scream like rabid cats.

You may despise the Ghast and all like them but they have been tortured by many a visitor of the Nether. All they do is float around, and occasionally shoot a harmless ball of fire at people's structures, but where's the harm in that?

One apparently invaded a mine and turned invisible. But then the whole mine was completely erased, so no-one knows why Porto has wounds on her elbows and why she keeps changing size. Wait, what are we talking about again?
