Royal Gallery Exhibit

The Royal Gallery Exhibit is a naturally-spawning structure exclusive to the Hamlet DLC. Two of them can be found in a room of the Palace. One of the Royal Gallery Exhibits contains a Can of Silly String while the other holds a Key to the City. They can be unlocked using a Royal Gallery Key, obtained from giving Queen Malfalfa a Royal Crown or Regal Scepter, to access the object within.
