This is an Icelandic tale of a family of giants and their cat. In the mountains of Iceland near the Dimmuborgir lava fields, it’s said that a family of terrible giants and their cat resides. The father, Leppaluoi, is lazy and often sends his wife, Gryla, out in search of naughty children for their favorite stew. Gryla is always hungry and is always on the look-out for bad people to eat. Once a year, on December 12th, Leppaluoi emerges in search of naughty children. It is recommended to be inside when night falls. Once Leppaluoi leaves, his 13 children and their big black cat all venture out for a little 13-day break from home.
