Update Mariana

Update Mariana would have the -y go to -128 instead of -64, include superdeep oceans, the bleeding effect, sharks, which will only attack you if you have bleeding, and the snareler, a mob like the nautilus but gives you water breathing, and the nautilus wouldn't be able to go past oceans that go to -64, but the snareler could. There would also be Sapphire ore, an upgrade to Netherite that could have a built in turtle shell, respiration, and if you shift near water, frost walker, however, these would only be able to be found in the Trench biome past -90. also, the chest plate would be able to make you swim faster, all 9 pieces would have 3.10K durability, can put an elytra on the chest plate and you can find a new structure, giant shipwrecks, and a new boss called the kracken. You could also find the new Shore trees, which would drop oranges, to make marmalade, which you can turn into a jar, throw food in, and turn it into marmalade'd meat. oranges and marmalade'd meat would also be able to cure the bleeding effect. snareler's are passive mobs, and sharks are neutral. The kraken would drop a ton of exp, which would be able to get you from level 0 to 75, a kraken arm, and kraken body, which is a 5x8x8 block which will give you around 19 pieces of kraken meat. the arm is a decoration like the dragon egg.
