When you collect all the music sheets, you go back to the piano and play it, and to the left you will find a secert entrance.

After you collect all the music sheets on the first and second floors you go back down to the lobby and play the harpsicord. A secret panel will open to the rear which leads to the two levels of Luvia's lab's. You will find the music sheets in different rooms in the treasure chests laying around. Use the floor map to guide you around to find the secret rooms. Also when in the attic you must save one barrel to jump over the crates to get to the extra treasure chest. If you break all the barrels tough luck start again. During this phase, save, save, save. I lost a lot of good treasure being headstrong.

Collect all of the music sheets and go back to the piano and play it. Then go to the right and you will find it. Note: It should say something like open trap door.

ONCE U PLAYED THE HARPRICHORD MOVE THE SCREEN SO THAT IT LOOKS LIKE U FIRST WALKED IN AND TO THE LEFT THERE IS A ROOM AT THE BOTTOM OF THE SCREEN GO IN THERE AND U NO THE REST
