Deep Sea Trek: Start with a Leviathan

Nautical + Cthulhu + Blood + Deep Sea Fear + Suspense Roddy is stranded on a deserted island, with only a dilapidated fishing boat about to sink? A drop of blood awakens Leviathan, a living ship that can swallow evolution! Swallow fish to produce venomous stingers, swallow warships to forge bone armor, and swallow evil objects to unlock deep-sea abilities. Clairvoyant lookouts, veteran ship doctors, heavy gunners, and mystics all join the team. Bloodbath pirate strongholds, defeat ghost ships, and clean up the evil sea areas along the way. Under the abyss, the giant beast is about to awaken, and only the bone ships that are constantly devouring can level the entire strait-laced deep sea.
