When I was a Peace Corps Volunteer in the Dominican Republic, Dominicans would talk about "La Cigüapa", which is kind of like a female boogie-man, but with backwards feet.
"cigüa" is a bird indigenous to the DR, and "guapa" usually means "pretty" in Spanish, but in Dominican spanish it means "angry." So it sort of comes out to "beautiful angry bird monster."
11169From the Wikipedia entry:
A Ciguapa is a fictional creature originating from the Dominican Republic. They are legendary women that live in the high mountains in the Dominican Republic. Since they are nocturnal, they come out at night to look for food. An odd feature to these women is that their feet are backwards, so you can never quite tell where the footprints came from. In some cases, people believe that they bring death, and are warned not to look them in the eye[1]
