Billiken

A billiken was a tiny humanoid creature that seemed to possess an uncanny amount of luck, and seemed to have the uncanny ability to pass such luck to those who had it in their possession. It appeared to be a four inch tall humanoid being, with a body resembling a baby's, but with an overlarge somewhat pointed head, and large feet. The one specimen recorded was naked. It was able to walk and climb, and showed a preference for climbing atop it's possessor's head and sitting with it's feet straight out front.
It was never settled whether the small creature was mortal, fey, or divine (or something else). Whenever the billiken was handed over to another person, it would usually chuckle. It was known as the "God (or spirit) of things the way they should be."
