(Rare) serpents that swim around the sea and melee attack players in random places.

One thing I like is that people cant really shoot arrows into the sea.

It would be nice if these serpents could destroy certain ships (and unclaimed structures?) with players in them.

How to kill: Im thinking cannons and melee attacks. This would promote the installment and use of cannons on ships!

Health: 400; Regeneration II Constantly

Damage: 18 hearts (naked) with Poison I for 00:05, Knocking you up

Speed: 5 blocks per second

(If this is too much, serpent man is always an option?)
