Find Yan and talk to him in six places. First, you find him in the building before 
the Ol' Pond (you will only see his eyes). Then, you need to find him in the Leaf 
Butterfly cage of Charity Square, to the left of the tall tree in the Jungle, behind 
the Smile door of Stormy Mountain, and behind the straw wall in the Haunted Mansion 
(these can be in any order). Finally, you need to find him in the Hidden Village.
