The thunderbird is a legendary creature in certain North American indigenous peoples' history and culture. It is considered a supernatural being of power and strength. It is especially important, and frequently depicted, in the art, songs and oral histories of many Pacific Northwest Coast cultures, but is also found in various forms among some peoples of the American Southwest, East Coast of the United States, Great Lakes, and Great Plains.
The kraken () is a legendary sea monster of gigantic size and cephalopod-like appearance in Scandinavian folklore. According to the Norse sagas, the kraken dwells off the coasts of Norway and Greenland and terrorizes nearby sailors. Authors over the years have postulated that the legend may have originated from sightings of giant squids that may grow to 13–15 meters (40–50 feet) in length. The sheer size and fearsome appearance attributed to the kraken have made it a common ocean-dwelling monster in various fictional works. The kraken has been the focus of many sailors passing the North Atlantic and especially sailors from the Nordic countries. Throughout the centuries, the kraken has been a staple of sailors' superstitions and mythos.
