Exploring the elegant music stage on the fourth floor of Luigi's Mansion 3 presents players with a delightful blend of artistic scenery and clever environmental puzzles. Known as The Great Stage, this particular level challenges your observation skills as you track down six unique, brightly colored gemstones hidden across the auditorium and backstage areas. Mastering this musical floor requires a firm grip on your Poltergust G-00 functions, including the Suction Shot, Dark-Light Device, and the helpful assistance of Gooigi.

Sucking Up the Auditorium Treasures

The journey toward full completion begins directly in the main seating area where the ghostly audience once watched the show. To find the first hidden treasure, navigate to the far left side of the auditorium rows where a specialized orchestra instrument rests against the wall. Using Luigi's powerful vacuum functions to spin the mechanisms on the tuba will release a beautiful gemstone directly into the open clearing. Another secret resides nearby within a hidden concession stand that requires pulling a structural plate away using your trusty plunger attachment.

Unlocking Secret Backstage Panels

Moving past the heavy curtains reveals the complex machinery that controls the main theater production and conceals rare collectibles. In the dressing room area, players can use the Dark-Light Device to illuminate an invisible cabinet tucked away in the corner. Flashing this ultraviolet beam reveals the hidden furniture piece, which then bursts open to reward your thorough exploration with another colorful prize. To secure the remaining items on this floor, players must also venture into the restroom facilities located right outside the main theater entrance hall.

Solving the Restroom Mechanics

The grand restrooms on the fourth floor contain intricate pipe setups that require seamless cooperation between Luigi and his gooey counterpart. By sending Gooigi through the metal floor drains, you can reach the subterranean water valves that control the pressure to the sinks above. Once the liquid flow is properly adjusted, returning to the surface and using the Suction Shot on the sink cabinets will expose a sparkling gem. Completing these engaging exploration labors across the entire stage area ensures you earn your prestigious collectible achievements smoothly.
