The creature has come to a stop just a couple of yards away from Watts. It's hard to get a good look at what shape it's in, mostly because the shape it's in appears to be shifting, morphing. It's standing unsteadily on two clawed feet, one hand braced against the tree, one digging and scratching at its shifting skull. The tattered, shredded remnants of what might be clothes hang off of it.

When Ryoji calls out to it, the monster lifts its head sharply to regard the two of them with two bright blue eyelights in narrowed eyesockets. It makes as though to move towards them, but a crack from somewhere in its spine makes it arch instead, letting out a howl of fresh pain. By that point, the creature has grown noticeably bigger than Sans. Even hunched over as it is, it's about as tall as Watts. If it could stand up, it would be even taller, but it seems to be in too much agony to manage that much.

But when the fresh wave of pain starts to fade, other details filter in. There's a human here, and something...almost human. Kill, it has to kill, it's the human's fault this happened, it's the human's fault he's like this...

It staggers a few steps towards Watts, looking straight through Ryoji to the scientist. One clawed hand - or maybe it's a paw at this point - swipes shakily through the air, but doesn't even come close to connecting with the human.
