Imagine a secret science experiment. Very secret. Very sciency. Should be perfectly safe, right? Right? Now, imagine a ghoul school in crisis. It's just like your school, only a bit more ghoulish. Well, a lot more ghoulish, but it still has students and teachers, like any proper school. It has a proper name, too: St. Squirmings' Ghoul School. And there's a crisis going on. And finally, imagine a headless monk, with a cold, so there's a lot of sniffing and snot involved.
