Ok, Team aqua have taken the orb and submarine. I got them out of that cave near lilycove, and now capt stern is saying I need to go to mossdeep and learn dive. How do I get to mossdeep!? I can't fly because I havnt been there before and there are rocks stopping me from surfing there from lilycove, and the ferry hasnt been built yet or somthing. What do I do?
