Nothing to say the slig didn't clock the sloggie immediately afterwards.
Also, even though that's how they "train" them, each slig is still their own individual and their personalities are going to vary. That one might be a bit more respectful and loving of the slogs than some of the other sligs. Who's to say?
My commentary on this was: "Oh hello worm like thing coming out of a wall composition. You are a fun composition to use over and over again when I don’t feel like working on a real background."
