Hey! I've been playing through the game so far, and have defeated all 4 of the elemental hotspots, but I'm unsure of what to do to make the Sulton's submarine reappear. I've completed all the optional content besides the Music one where the woman upstairs is looking for fancy instruments. I have the Weird Didgeridoo from the Volcano Island, and am aware of the violin upstairs in the Wind Village, but am unsure what to do since she doesn't take the weird Didgeridoo and I can't get the Violin from the girl. I've gone back through all of the dungeons and can't think of where else to go. Any help would be appreciated!
