In Bengali folklore, a Shakchunni is the ghost of a married woman. They usually wear Shankha, the coral or shell bangles that they were given as a part of their wedding ceremony. In this picture, from a classic folklore book, the Shakchunni is spreading cow dung mixed with water.
Old Lady and the Devil is an American children’s song about a farmer who gives up his “scolding” wife to Satan. When demons come to take her, the Old Woman “beats out the(ir) brains”, but is ultimately taken away by The Devil in a sack. ⠀
