The world-renowned fairy tale diagnostician Dr. Grimm is having a very bad day. He's got twins with Type 2 diabetes, a boy the size of a thumb who needs massive doses of growth hormone, a gnome with an identity crisis, a princess with insomnia, and a wolf who needs a grannyectomy. And that's just in the clinic. Grimm's main case is a very pale girl who fell into a coma after eating a toxic candied apple!
