During A-2: Gear Up!, Luigi must head into the Parlor to obtain a gear piece. He must use the Poltergust 5000 to make the phonograph play and cause two Greenies and a Slammer to appear. Luigi vacuums them up and obtains another Gear Piece.
During A-4: Visual Tricks, Luigi must head into the Parlor after the door to the Lab disappears. As Luigi heads into the Parlor, he spots Spirit Balls fazing through a grandfather clock and makes it disappear. The fire of the nearby fireplace is put out and Luigi uses it to get into the Lab.
