This is a little sketch by the awesome  FleaTrollus that I colored up.

Caranoctian trolls don't have molars and can't chew, so they tend to be sloppy eaters. Like their reptilian ancestors, they usually tear off big chunks of food, or, in the case of this little swamp critter, they'll gulp down the whole thing, bones and hair and eyeballs and all (hair is roughage!). Obviously, table manners are not a concept in troll society.

I decided this is Varamul, since I don't have any pictures of that character and I hadn't drawn any trolls with this particular coloration. That blue isn't make-up, it's natural. Nerd note: the blue in troll skin is structural, due to Tyndall scattering, not a pigment. Albino trolls will often have vivid blue markings.
