Dugal, the kelpie from The Bestiary Project.
When I say his sense of humor is horrendous, I mean it. He thinks getting people stuck to him with no warning, turning back into a horse monster and running headlong into the nearest large body of water, only letting the victim go when they are about to lose consciousness underwater is the height of hilarity.
I keep doing things where he appears, so I figured it was time to finish the half-done ref sheet for him. Yeehaw, another horsefaced character.
I should do the protagonists of the story one of these days.
