The training room in Luigi's Mansion is supposed to be the only ghost-free space in the game, but the executable code hides a file called mg_gene1, a ghost generator using the same naming convention that spawns every other enemy in the game. That leftover file suggests the tutorial was originally meant to throw practice ghosts at players before the mansion proper even opened up. Part of an ongoing series digging through Luigi's Mansion's unused files, prototype builds, and development history.
