Elfie is just that, an Elf... one of Santa's elves. Elfie visits your house during Christmas season... and he's mischievous. One day he may be inside the cookie jar eating cookes... the next on the counter covered in chocolate syrup, the next in the fridge eating a bowl of cool whip. You never know where you're going to find him.
Upon waking kids search for Elfie.... if you're hoping to sleep in forget it... the search for Elfie trumps everything.
Not sure when this started... wasn't around when I was a kid.. .and obviously not when you were a kid either... but today Elfie is in nearly every home.
