I'd done many sketches of the mythical kelpie in the past, and always like the idea of a more or less approachable looking horse: Except, of course, for that terrifying, rotting skeletal head and writhing kelp-like... appendages? The (careless) victims don't know what they're sitting on until it's too late. How unpleasant!
