It's kind of silly timing to be suggesting this at the end of June, but it just occurred to me that the amphisbaena, a two-headed serpent from Greek mythology, could be a cool theme for a new slithering minion. Maybe something the artists would want to consider for next year?

(I searched the forums and didn't see the word "amphisbaena", so I don't think this has been suggested before, but my apologies if it has and I missed it!)
