The Bwbachod are friendly goblins who will help you out with chores at home or on the farm, like making butter, if you behave correctly. That means making a good fire last thing at night and leaving a bowl of cream out for the Bwbachod to drink. It also means drinking a good deal of ale yourself, for the Bwbachod hate teetotallers. There was once a Baptist preacher in Cardiganshire who was much fonder of prayers than of ale so a Bwbach took to pestering him while he prayed: jerking the stool from under him; jangling the fire-irons on the hearth; making the dogs howl; frightening the farm-boy into fits of screaming by grinning through the window. At last the Bwbach took on the exact aspect of the preacher and confronted him as he crossed a field. The preacher fainted in fright. When he eventually came to he packed up and left Cardiganshire never to return.
