Better ocean

Add an another boss for example A giant angler fish that could drop an armor trim or other thing it is found in deep ocean. Maybe ad like an under water exploration vehicle that cans be found in under water caves and repaired with iron and Redstone and then you can explore the ocean with drowning so basically a submarine . a sort of Mariana Trench would be cool with like dark blocks the desperate you go into it and you could find like cool abyssal mob like a spider crab its basically a big white and orange crab that lives in the abyss Make the terrain of the ocean have more sand and less gravel clay and dirt
