Pooka

Tales of fairies and their magical powers are popular all over Ireland but the most feared of these fairy people is the Pooka. This mischievous fairy comes out at night to create havoc and cause mischief. The Pooka will trick you into doing things you don't want, or even kidnap you. The Pooka's ability to change form and shape makes it even more scary . So, you can never be sure if you have come face to face with a Pooka, or not.
The most common form this magical creature takes is that of a yellow-eyed, dark horse with a long mane which blows in the wind. It tramples crops and breaks fences in the countryside as it goes on its nightly rampage.

Sometimes it follows the ships to sea. Often at night, as the black horse, the pooka will take a man for a ride clear around the country at breakneck speed until he loses his grip and flies headlong into a bog ditch.
