Puca is a trickster fairy that can be equally helpful and confusing at the same time. He spends most of his time climbing around the trees, sleeping in the branches, and fooling the other creatures in the forest with his pranks. He is also known to be a changeling able to transform into animals like a rabbit, a goat, or a cat. The disguises are used to enter human settlements to steal food or trick people for his own amusement. In order to please Puca and keep his trickster ways to himself, people will leave a share or their crop for him at the edge of the forest as a present.
