A new sea monster is needed, don't you think?
A megalodon, kraken? Only two sea monsters in a game where 70% of the game is on the sea. This would be like the megalodon, disappearing near shallow shore and appearing randomly. The rarest whale would be the moby's whale.
Depending on their rarity, they would be different sizes, different spawning rates, difficulty and amount of hits it takes.
Upon defeating Moby's whale it will drop random loot and one athena chest, and a random emissary flag as of course a ship was swallowed.
This could also be a new bilge rats, or a completely new system of community events.
