Pwca
The Welsh Pwca is related to the Irish Pooka, the Cornish Bucca and the Manx Buggane. It lives by itself and can act like Brownie or house spirt, although it can also choose to behave as it pleases if it is not respected.
John and Caitlin Matthews, The Element Encyclopaedia of Magical Creatures, 2013, Pwca, p 376
