Ok man here you go...
Talk to Luna in the Entrance hall to get this quest. Her lost items are
1. Great Hall: On a table
2. Entrance Courtyard: Take the broom and sweep the leaves to the right
to uncover her next missing item
3. Clock Courtyard: In front of the fountain
4. Library: on the table
5. Viaduct Entrance
Talk to luna again when you've found them all."
I got that info from this link http://www.gamefaqs.com/console/wii/file/934380/49075
Went through a little work to get that info so I think I deserve some rep, enjoy...
