The Bwbach, or Boobach, is the good-natured goblin which does good turns for the tidy Welsh maid who wins its favour by a certain course of behaviour recommended by long tradition. The maid having swept the kitchen, makes a good fire the last thing at night, and having put the churn, filled with cream, on the whitened hearth, with a basin of fresh cream for the Bwbach on the hob, goes to bed to await the event. In the morning she finds (if she is in luck) that the Bwbach has emptied the basin of cream, and plied the churn-dasher so well that the maid has but to give a thump or two to bring the butter in a great lump. Like the Ellyll which it so much resembles, the Bwbach does not approve of dissenters and their ways, and especially strong is its aversion to total abstainers.
