Galafses the Shroomed is one of The Lords Of Minecraftia. He accidental got himself turned himself into a Mooshroom while creating the Mushroom Biome. It was one of the funniest and most unfortunate accidents ever to happen in the universe. Even he laughed in his own Mooshroomy way.
He has figured out a way to turn himself back, but has gotten so attached to his mushroomy body that he doesn't want to turn back (in fact he is tempted to tamper with the machine so he can still access his Mooshroom form by will).
