While this one might seem to fall under the same area as The Missing Link and Kamala, The Boogeyman kind of has a different hook going on, as he's arguably more of the tales that parents tell their children to get them to behave. If you go with this one, just make sure you get the clock and study up on your nursery rhymes. Really, though, the best reason to choose this as your costume would have to be that it's the ultimate excuse for pigging out on gummy worms all night long. Few other costumes offer that kind of luxury.
