Related: Or one of these mythical creatures:
Basa-Jaun (Homme de Bouc): An ogre of the Basque in northwestern Spain, whose name means "lord of the woods". He is given credit for teaching mankind the art of agriculture and forging. He lives high in the Pyrenean Mountains, in the woods and caves where he protects the flocks of sheep and goats from predators and thunderstorms. But he has a malignant nature and will trap and torture humans if they stray into his domain. In some stories, he is described as a spirit that is mischievous, but not malignant.
Bicha: In Spanish folklore, a monster depicted as having the body of a bull and the head and face of a human.
Caballucos del diablo: "Devil's small horses". In Cantabria (northern Spain), it is told that those creatures appear with a terrific cry at Saint John's Eve, amongst fire and smoke. There are seven winged horses, of seven different colors: red, orange, yellow, white, black, blue and green. The red one is the strongest, and their leader. All the horses are mounted by demons. During this one night, they roam the land, in search of four-leaf clovers, that are rare, and considered as powerful lucky charms. The mission of the horses and riders is to destroy as many four-leaf clovers as they can find, to avoid people searching them next morning to benefit from this gift.
Culebre: In Cantabrian (northern Spain) folklore, it is a dragon-like creature, or a snake with two bat-like wings, that exhales fire and sulfur. Culebres are very dangerous, but it is worth fighting against them, because they usually hide huge treasures in their dens.
Dones d'aigua: Dones d'aigua (Maids of the Water): are typical beings of Cataluña, and they appear in many myths. They live in any place where they can find clean water (wells, springs, fountains, lakes), but they can also be found in woods and caves. They appear as women of incredible beauty, although half of their body can be fish- or bird-like (as for many other faeries of Spanish folklore and Indo-European myths). Dones d'aigua often guards wonderful treasures. They are always good and kind to humans.
Duende: A Spanish house spirit, these are færies from the Iberian Peninsula, Mexico, Central and South America. They appear as middle-aged women dressed in green robes and with long icicle like fingers. They are extremely jealous of humans and are known to take over human houses, throwing things and moving furniture about. It can be seen by anyone who bends low enough to look backwards through his legs.
Espumeros: "Foamers". Marine beings form the Cantabric (northern Spain) coast. Their appearance is that of fat children. They wear tunics that are the colour of algae. They like to play in top of the waves, forming small whirlpools in them. The Sirens are their friends, and they usually give the Espumeros seashell trumpets as a gift. As those marine beings are very good willing and helpful to fishermen, they blow into their sea trumpets when there is going to be a storm. Thus the seamen are warned that it is safer to return to port. Espumeros also help farmers sometimes, carrying water in their trumpets to water the crops.
Ijanas: Female creatures of Cantabrian (northern Spain) folklore, they live in caves, are always naked, and have breasts so long, that to walk they must put them over their shoulders. Very greedy and unquiet, they spend their time looking for food, destroying beehives in search of honey and entering houses without permission. Yet, unless bothered, they are not particularly dangerous, just very much annoying.
