For those of you who have seen me play Minecraft, you know this guy, but for everyone else:
Exotria is an IRL pal of mine who likes to mess around with me while I play Minecraft. You can design your own characters, and one particular day a couple or so weeks ago he visited my house. The two of us came up with this design: some sort of blue grinning ghoul that lurks the caverns below the world, ferrying buckets of lava with him to the surface to wreak havoc.
