A small (expert) world filled with water. water ends at space and sky islands are removed. You can find sand islands instead, containing the same items and some potions.
I also let you start with some items to make up for all the stuff you can't do to make this more resonable (hook,flippers,silver pickaxe)
Dungeon entrance is changed so you can beat the boss.
Holes in the world are blocked of by gold bricks so the corruption tunnels dont get flood for example.
you start here in a sunken ship:
