 Some ghosts cannot be captured easily until Luigi locates three special medallions, each granting the Poltergust with the ability to suck up certain elements from the rooms and use them to capture special ghosts lying within the mansion.In addition to capturing the regular ghosts in the mansion, Luigi must also draw out special "portrait ghosts" from some rooms, each requiring a condition be met to make them available for capture.Once all the ghosts in a room are captured, it brightens up; the music also changes accordingly, being pleasantly whistled by Luigi, while being haunted and spooky when filled with ghosts, with Luigi humming nervously to the tune.
