A version of the "monster under your bed," which is feared by people who are afraid of the dark. It is believed that if you leave one of your legs out of the blanket while you're sleeping so it doesn't get too hot for you, this mysterious being will grab the exposed leg and take you into his evil lair.

It may also just be your cat. But what if you don't own a cat?
"I'm hot."

"Just pull the blanket up."

"I can't. The blanket leg demon will steal me away."

"*Sigh* Will you ever let that go?"
