A picture of a tpeugs, of course. My idea is that it'd be one of those Japanese fish prints, close up on its head, and a speech bubble saying "Tpeugs" coming out of its mouth. However, I lack a picture of one of those, so I didn't make one myself.
Anybody else up for making one? Either that or I'll track down one and make the icon myself, although I think Elynne (as the community creator) would have to upload it for me. (:P
