New sea monsters like a serpent, whale or crab

So the serpent is big and green and can coils around your ship so it can’t move unless damaged. It could bite the ship damaging it. It could spit poison on the deck and you have to get it out with water. This could be the first sea monster to target masts. It could drop serpent scales for hunters call. Whale so the leviathan a giant wale more like a meg than kraken you can run if you want or fight. It could get under your ship and use its blow hole to shoot your ship up in the air. It could ram it’s self into your ship, and make holes, but the real selling point is that when your ship is almost dead it could jump out of the water and split it in half. Thank you for reading.
