I have finished getting the tiki parts but I cannot exit the submarine! How do I get out of there? The walkthrough says to exit in the bottom middle but I can't! Help?
Ok! I figured it out!
Take a look at the map in the submarine, it's to the right of the arrows to move the sub. The highlighted dot indicates where you currently are underwater, and the portion at the bottom where it appears that you can move off the map is where to go to get back to the base.
So simple!
