This might seem drastically different, but the face of this new design can still curl up into the more toucan-like shape of the original version, and the body can fold up the same way at rest. So when "Standing," this has the same design the old one does, but its "flight mode" is now a bit different.
This is to emphasize that the plaguemen aren't bird-derived; for this update I borrowed most heavily from chimaera fish!
It will go "public" once the updated art is complete for the other plaguemen; the basic Mumblegog will actually remain exactly the same as its existing art, but colorized!
