Now I feel like the Ocean isn't dangerous or interesting enough. I think it needs a few of these features I'm about to mention.

1. Storms: I think when it's stormy over the ocean it should have these big waves, these waves would destroy any small boats. And if you are pushed by the wave alone you will get forced under to the bottom of the sea.

2. Bigger boats: It would be cool if there were bigger boats that sailed faster and could withstand the waves I mentioned, also these boats would be able to hold chests and have a deck that you could walk on.

3. Sea life: Sharks, wales, minecraft unique mobs you get it.

4. Sea plants and potion ingredients: More plants for potion ingredients that would compel us to go out to sea more.

5. Cool sound that actually makes you feel like you are at sea like seagulls and wave crashing sounds.

6. Unique fish that can be fished up: Now there should be certain fish that can only be fished up in the deep ocean that would be very cool.
