The Boogey man is quite a horrid monster thats a master of disguise.

Being able to take the form of almost anything, and being lighting fast  it hides in children's bedrooms waiting till the lights go out. And after that the place can become a living nightmare! Horrible scratching noises under the bed, Deformed shadows danceing around the walls, all the way to The BoogeyMan dragging the poor child to his nightmarish dimension! One nessary precaution against BoogeyMen is putting some bread and milk near the door.
