Some claim that if you see it in your peripheral vision, its form resembles some eldritch abomination of wings and and eyes and mouths and limbs, but viewing it directly simply shows your average albino not-cat. Sometimes, when it stretches or yawns, it will accidently let down it's façade and stretch far too unnaturally for a not-cat, or nearly unhinge its jaw, though those moments are so few and rare that anyone who might witness one can't be sure that they weren't just imagining it.
It doesn't talk much and moreso just stares, and whenever teeth does talk it almost sounds like it's just repeating words that it has heard previously. The intonations never really sound quite right, and tend to have an unnatural lilt to them. Regardless of its limits in communication, its cool temperament, or rather lack of expressions and reactions, and curious nature make it a good listener. It does seem to enjoy the company of all sorts of not-cats, regardless of energy-level or chattiness.
It seems to be incredibly fond of swimming, and enjoys floating around in cool waters on sunny days. Temperature doesn't seem to have an effect on it either, with it never showing any signs of being cold, but some do notice that it seems more melt-y on hotter days.
teeth is technically the founder of teeth town, though its leadership is quite lax as the town is rather good at managing itself. It tends to walk around the village perimeters, observing the other not-cats, sometimes giving a nod of acknowledgement when walking past, but otherwise tending to do its own thing, whatever it may be.
Its cat hoard consists of an incredibly comprehensive collection of teeth. Far too many to be fully comfortable with, sure, but an admirable amount of them of all shapes and sizes, and from all sorts of animals. Some of them are not recognizable at all however, and one does wonder where they came from.
Whenever Nestor finds young not-cats in need of family, teeth is always the first to volunteer. Interestingly enough, young not-cats that encounter teeth never experience discomfort in regards to its odd self, and this does not change when they grow up, though the same cannot be said for adult not-cats that encounter it.
