Solomon's Key/Console Bonus

Hidden Room
The location of the items in the hidden room change every time, but it appears that there is a consistent number of them in every board. There are many score increasing items (like the coins and broaches), but that isn't the fun part of the bonus room. The following is an inventory of the item that you really want to look for:
 * (1) additional fairy bell
 * (2) blue diamond
 * (1) orange diamond
 * (1) orange hourglass
 * (1) 1/2 gray bottle
