Hedolga is Troll character I've had since 2007, and don't draw nearly as often as I should. I think the punch line here works just fine as a non-sequitur, but in the spirit of ruining the joke I'll explain. According to Gnomes by Wil Huygen, Trolls just love to burn little gnome butts on grindstones. I suspect an afternoon of Troll domination is a favorite Gnome pass-time. Cheeky little buggers.
