We are looking for another hollow log to make the additional music instrument the student wants. So she can give us the large sturdy metal pole for the BBQ pit for the chef. Will one eventually come ashore so we can complete this task? Also, after we complete the chef's tasks, the doctor's tasks and receive the last piece of the map. Does the map lead us off the island and that's the end of the game? Or will there be more tasks before we finish the game?
