In ancient Albanian folklore, Bolla is a snake-like (or dragon-like) creature that sleeps throughout the entire year. On Saint George's Day, it will open its eyes and look into the world. A human unfortunate enough to be spotted by Bolla will be devoured instantly. At the end of a twelve-year cycle it mutates into another being, called Kulshedra. This creature is a horrible, fire-breathing dragon with nine tongues. Kulshedra is sometimes also represented as an enormous woman with a hairy body and hanging breasts. The monster can cause a shortage of water and it requires human sacrifices to propitiate it. The creature is also known as Bullar in south Albania.
