For centuries, fishermen from Norway and Greenland have told tales of a terrifying sea monster: the kraken. Supposedly, this vast creature has giant tentacles that can pluck you from your boat and drag you to the depths of the ocean. You can't see it coming, because it lurks deep beneath you in the dark water. But if you suddenly find yourself catching a great many fish, you should flee: the kraken might be beneath you, scaring the fish towards the surface.
