Jenny Greenteeth has been a part of English folklore for generations and has her roots in antiquity where she, alongside many other related water-demons, would be said to haunt rivers and ponds - dragging any children or elderly that strayed too near into the water to be devoured: Jenny Greenteeth was said to be a particularly gruesome specimen of such a water-hag and was fond of drowning children, for this reason parents would tell their children to stay clear of bodies of water unsupervised - in this regard Jenny Greenteeth acted as an effective deterrent to youthful curiosity, though their were always some foolish enough to tempt fate.
