Luigi is notified he has won a mansion in a contest he did not enter. He informs Mario, and they agree to meet up outside the mansion that evening. Luigi follows a map to the mansion, finding it more sinister looking than the supplied photo. With Mario nowhere to be found, Luigi enters the mansion alone. He encounters a ghost, which attacks him, but is unexpectedly saved by a scientist who unsuccessfully tries to suck up the ghost with a vacuum cleaner. The two evacuate before more ghosts can arrive, and the man introduces himself as Professor Elvin Gadd, or E. Gadd for short.
