Cirein-cròin

Cirein-cròin is a Scottish Gaelic sea monster that was so massive it was said that it ate 7 whales to be full. It would desguise itself as a small shiny fish and transform when it was caught to fool fishermen. I think it could be an interesting event, if not an actual mob. If you go across any ocean or fish from the ocean, you have a chance (Maybe 5-8%) of being pulled to the nearest ruin or ocean monument. You are also struck with blindness as you see the mighty Cirein-cròin swim out of view. I think it could make fishing or ocean travel a bit more risky. If you have Luck of the Sea, Cirein-cròin will drop a diamond with you when it grabs you, but the chance of getting grabbed is slimmer.
