Did the Creature's Expression Change?

It looked like a predominantly black haired creature. Some of the hair was long on it. On its back side, some of the hair looked thinner in arias than on its back, where it looked more furry. As it went by me, i'm going to say it was literally five, seven feet. But the side of its thigh, its hair was missing em. If its arms are always going back and forth, maybe it's going to rub the hair raw. And remember, at one point, how do you know? When is hand came up, its fingers kind of at the top part closed. I just didn't know if that thing was going to make a fist
