I'm glad you asked! A few years ago in World of Warcraft, I came across an area on a plateau west of Thunder Bluff where the critters were at war. There were rabbits with axes in their mouths, and prairie dogs with daggers wearing WWI german spiked helmets; but the first thing I ran across that made me wonder if I was hallucinating was a mouse with two flintlocks wearing a demonic-looking skull on its head.

So I immediately put Eliza in this getup and... skullmouse.

If you're somehow still reading this, you can find a picture if you google 'warcraft skullmouse.'
