Phooka (Puca)

The Phooka is a harmless Irish kobold who appears in a great diversity of animal shapes. He can be seen in the shape of a dog or horse, usually pitch-black with fiery eyes. As an apparently tame and shabby pony, the Phooka offers careless travelers a ride on its back. But as soon as the traveler mounts the horse, he is in for a hell-ride through marshes and thorn-bushes. Then suddenly, he is thrown into a ditch or mudpool and the chuckling he hears is the Phooka galloping away.

Sometimes he appears in the form of an eagle and carries people away on his back.
