...I'll admit. It took me a bit to figure out that the tail is supposed to somehow be cooling. Do snakes work that way?
For that matter, now I have all sorts of questions about whether a snake-lady is warm-blooded or cold-blooded. :D
Well, I don't want it said that I don't listen to sloths!
Well I don't know about her character, but snakes are cold-blooded which from what I understand, just means they cannot create their own body heat. (among other things)
So if you go into a pet store, snakes and other lizards will actually have a heat lamp above them in their cage.
