The Great Stage

The Great Stage is the fourth floor of The Last Resort in Luigi's Mansion 3. Luigi first explores the floor after having acquired the fourth floor elevator button from Chef Soulfflé and a bunch of mice in Mezzanine.

Eventually, Luigi discovers Toad's portrait being guarded by Amadeus Wolfgeist. After defeating the ghost, Luigi rescues Toad and obtains the sixth floor elevator button. He delivers Toad to E. Gadd in his lab, and heads up to the sixth floor.
