The Pooka or Puca or Pwca is a shape-shifting creature from Celtic foklore that can change into a horse, goat, cat, dog, or hare. If they take human form, they’ll have an animal feature like ears or a tail. Pookas are tricksters and can bring good or bad fortune. The character of Puck in Shakespeare’s A Midsummer Night’s Dream was based on this creature. Image: British Goblins, W Sikes, 1881
