Scuba Diving Adventure GP - Detailed idea

Last summer when I got Island Living, I literally build underwater in one of the lots in Sulani that had mostly the sea on it. It wasn't too hard, I just made sure that I had my bb.moveobjects on. Then I selected off-the-grid objects. Had to make sure that the fridge & Island firepit was on land though. It was so nice to finally have my Ariel Mermaid be an actual mermaid & live literally under the sea instead of a home in a swimming pool.
