of the púca brushing by, and called out to him, offering a coat. The púca appeared in the guise of a young bull, and told him to come to the old mill at night. From that time onward, the púca came secretly at night and performed all the work of milling the sacks of corn into flour. Padraig fell asleep the first time, but later concealed himself in a chest to catch sight of them, and later made a present of a fine silk suit. This unexpectedly caused the púca to go off to "see a little of the world" and cease its work. But by then the farmer's wealth allowed him to retire and give his son an education. Later, at Padraig's wedding, the púca left a gift of a golden cup filled with drink that evidently ensured their happiness. Another example of the púca as a benevolent or protective entity comes in tales where the creature intervenes before a terrible accident or before the person is about to happen upon a malevolent fairy or spirit. In several of the regional variants of the stories where the púca is acting as a guardian, the púca identifies itself to the bewildered human. This is particularly noteworthy as it is in contrast to the lore of many other folkloric beings, who guard their identities or names from humans. There are stories of some púcaí being blood-thirsty and vampire-like creatures. Other stories even say some are man-eating beings, hunting down, killing, and eating their victims. Morphology and physiology According to legend, the púca is a deft shapeshifter, capable of assuming a variety of terrifying or pleasing forms. It can take a human form, but will often have animal features, such as ears or a tail. As an animal, the púca will most commonly appear as a horse, cat, rabbit, raven, fox, wolf, goat, goblin, or dog. No matter what shape the púca takes, its fur is almost always dark. It most commonly takes the form of a sleek black horse with a flowing mane and luminescent golden eyes. (The Manx glashtyn also takes on human form, but he usually betrays his horse's ears and is analogous to the each uisce.) If a human is enticed onto a púca's back, it has been known to give them a wild ride; however, unlike a kelpie, which will take its rider and dive into the
