I have several loose ends on each isle, I know I am missing one simple thing to move on, just missing it. Here is where I am
[spoiler]I have taken my little ballon ride, got the shoes & visted the winged city, got the memory gem, went to that darn maze, found paton, I cant dig with my hands so left the maze and thought I would run accross something, Looking for the White King from Isle of wonder. I spoke to everyone and not sure what to do next[/spoiler]
I think your best way to go right now is to find a way into Beast's Castle. You have what you need to get there.
