What is pooka meaning?

Pooka is a mythical creature in Irish folklore typically depicted as a small, mischievous creature in the form of a black horse, goat, or rabbit. The word "pooka" is derived from the Irish word "phuca" meaning spirit or ghost. In folklore, the pooka is known for playing pranks, but it can also be helpful to humans. The pooka is often associated with Samhain (Halloween), and it was believed that during this time, it could take on a more threatening form.
