"It was, indeed, on a skeletal horse. Blue flame crackled over the creature's bones as it trotted forward; Miss Flitworth found herself wondering whether it was a real skeleton, animated in some way, something that had once been the inside of a horse, or a skeletal creature in its own right. It was a ridiculous chain of thought to follow, but it was better than dwelling on the ghastly reality that was approaching."
Their eyes are slightly too close together, moved frontally to give them better binocular vision than any normal horse. Their nostrils and mouths look normal at first, but then one of them wrinkles its lips and I see fangs, and the edges of the lips retract much further than is natural for a grass-eater, revealing dentition more like something out of a nightmare concocted by H. R. Giger than anything a horse doctor might recognize. Oh, and the eyes? I mentioned that they’re blue, and they pulse, but did I remember to say that they glow?
