"Water bull." In Manx folklore, a bull which lived in swamps and shallow pools. Occasionally it left its haunts to roam among the farm cattle, but it only begets monsters and strangely formed beasts. Its bellowing reputedly made the ground tremble. There used to be a tarroo ushtey between the village of Andreas and the sea to the west, before the ground was drained. Others have been noticed at Ramsey and Slegaby.
