Sunken greatness

I think that there should be deeper oceans with new a structure like a sunken city deep in the ocean in addition there should be full turtle armor with the durability of a leather and copper armor the chest plate will have a turtle shell that protects the player from attacks from behind but it makes the player slow when equipped but it also has the ability to increase the momentum of the player when falling by double making it more critical when with a mace the armor will need turtle scutes and iron there should be another variant of the trident which is black and golden it will be wielded by a new mob that is a new type of boss called sunken king that wears a crown looks more distinct from the other drowns ,the black trident will have the ability to go through 3 mobs and can make the holder riptide 6 times faster than a normal enchanted riptide trident it can be thrown with loyalty without even being enchanted, the boss will ride a huge zombified fish which is bigger than a ravager by a few, there will also be another type of mob called sunken guards they spawn riding rideable zombified turtles. And last of all even if it's not added I can atleast know that mojang will make a better one.
