Earlier this summer, the kids in one of the creative writing camps I teach through The Cabin Idaho (a Boise-based literary center) came up with an imaginary troll named Evil Knievel that haunts the tiny, hobbit-looking supply closet in one of the classrooms there.

It’s a total hobbit hole, only rectangular.
Naturally, after the kids had invented it, they wanted to feed it.
So they started drawing pictures of food and slipping them under the door for the troll.
