Puca

The púca (Irish for goblin), pooka, phouka, phooka, phooca or púka is a primarily a creature of Irish folklore. Considered to be both bringers of good and bad fortune, they could either help or hinder rural and marine communities. The creatures were said to be shape changers which could take the appearance of black horses, goats and rabbits. The pooka may be regarded as being either menacing or beneficent.

Fairy mythologist Thomas Keightley said "notions respecting it are very vague," and in a brief description gives an account collected by Croker from a boy living near Killarney that "old people used to say that the Pookas were very numerous...long ago..., were wicked-minded, black-looking, bad things...that would come in the form of wild colts, with chains hanging about them." and that did much to harm unwary travelers. Also, children were warned not to eat overripe blackberries, because this was a sign that the pooka has befouled them. In contrast, the phouka is represented as being helpful to farmers by Lady Wilde, who relates the following tale. A farmer's son named Phadraig one day noticed the invisible presence of the phouka brushing by, and called out to him, offering a coat. The phouka appeared in the guise of a young bull, and told him to come to the old mill at night. From that time onward, the phoukas came secretly at night and performed all the work of milling the sacks of corn into flour. Phadraig 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 phoukas to go off to "see a little of the world" and cease their work. But by then the farmer's wealth allowed him to retire and give his son an education. Later, at Phadraic's wedding, the phouka left a gift of a golden cup filled with drink that evidently ensured their happiness.
