Nothing terribly imaginative in this conversion. Just a chaos spawn with a rat head, spikes, and an extra arm with a sword. I didn't think the
original chaos spawn feet made it appear as much like a rat ogre as it should, so I used the plastic rat ogre legs to lengthen them some. This
turned out well, and even gave it a more top-heavy skinny-waisted appearance like the rat ogres.
