Chibi's are mostly focused on being cute and deformed (which sometimes translates into bobbleheads, but not always). So if you are looking at it as a baby serpenth, then I can see why you're having some difficulties with it. But yeah, chibi pets aren't actually intended to be baby versions, just ridiculously cute and squished around a bit!
And that is very interesting about snake mouths. Not something I've had cause to look up myself but that's a neat little evolutionary trick they've got there.
Ha ha, no, I don't think you're being mean. The inchworm/caterpillar-ness of that particular one was intentional to push the cute/deformed idea. So that you're seeing that isn't bad (although if it's actively bothersome to you then that's unfortunate).
Yep, that was part of the reason for the color choice! ;) And no problem! Hope it helped a little. ^^
