There is a story about a boy who was leaving his school one evening when he heard a noise behind him. Looking back, he saw a beautiful girl sitting at a window. The girl had her arms propped up on the window sill and was just staring out at him. He wondered why she was there, because it was an all-boys school.
When she saw him looking back at her, the girl smiled and hugged herself so that she was holding her elbows. Then suddenly, she leaped out of the window and landed on the ground outside. The boy realized with horror, that she was missing the lower half of her body.
She made her way towards him, clawing along the ground and running on her elbows making a teke-teke-teke-teke-teke sound. The boy was filled with terror and revulsion. He tried to run, but he was frozen to the spot. Within seconds, she was upon him and she took out a scythe and cut him in half, making him into one of her own.
She is also known as “bata-bata” (again, the sound of it running on its elbows) or “The Girl That Runs On Her Elbows.”
(Trivia: “Bata” in Filipino means kid or child).
It is also similar to the story of Kuchisake-Onna (the Slit-Mouth Woman) and the story of Kashima Reiko. The American version is called Click Clack.
