So from what I've seen of 1.13 there are alot of ocean revamps. So first: I suggest revamping the oceans for coral biomes and fish and the drowned to be spawned. Second: I suggest a way to be able to craft the Trident or make it differently. Third: Make the trident be able to have sharpness. (I'm not sure how possible this last one is but I really wish Mojang had done it in the first place.) Fourth: The Idea of Shipwrecks is a cool one but it would be something that if it regenerated it would be abused and if not then it would be useless. So I suggest a nerf to the contents of the shipwreck. Maybe they could contain strange moats and basic shards. Fifth: Orange Trees
