"Kraken" comes from the German word for octopus.

Legends hold that the Kraken would attack a ship and sink it by wrapping its many arms around the ship. The ship's crew would either drown or be eaten by the monster.

These legendary massive sea monsters used to live in the depths of the sea off the coasts of Norway and Iceland, but since have grown smaller and more rigid over the years.

Scientists have named the newly discovered creature "the Klacken." These creatures now share a symbiotic relationship with keyboard enthusiasts and can be found deep under the pacific ocean or in the top most reaches of mechanical keyboards.
