My problem with teethling's tail is that it swings a lot from its "root", strengthless, like a chunk of rubber toy. If the tail's swing animation was: at root, only swing a little, the further goes down, the more it swings, as if the root of the tail start the movement, and drive the rest to move along with it, like a whip. And at the tip, it could swing as joyful as it want.
