Deep fried calamari sounds amazing to eat right now, and the gigantic squid or kraken probably could of fed like 10,000 people or so. Lol .no I don't think they did eat the gigantic squid or kraken but took it to some type of lab for scientific research on a species they thought was extinct.

The kraken isn't serpent like though and it's more like a gigantic squid which do exist thanks to the tsunami or hurricane off the coast of Japan and china a few years ago and the supposedly extinct gigantic squid or kraken was Wash up on their shoreline proving that scientist were wrong and they aren't extinct overall.

Maybe a sea dragon or a prehistoric sea dwelling dinosaur, that didn't die with the rest of them, ocean hydra,or maybe it's more like the loch Ness monster and maybe the music and people attracted it or maybe the yacht party was a sacrifice of some kind by someone on the yacht and only 20 to 25 percent of the ocean has been explored so far because of how deep the ocean water and how bad the pressure is down in the darkest depths of like Marianna's trench and who knows what ancient sea creatures call a place like that home?
