A grindylow is a water spirit that originated from folktales in the English county of Yorkshire.
Grindylows grab little children with their long arms and fingers and devour them if they came close to the edge of pools, marshes, or ponds. Peg Powler and Jenny Greenteeth are similar water spirits.
Grindylows were used as a ploy to keep children from getting in the cold water in the area.
