Fan Casting Luigi's Mansion

Luigi's Mansion starts when Luigi got a message saying that he won a mansion in a contest. He told his brother, Mario about this mansion because he didn't even enter a contest. Mario runs into the house immediately to investigate, but then disappeared into the mansion. Then Luigi heads straight into the mansion, but Mario is nowhere to be seen as Luigi believes that he must've arrived early or late. All the doors are locked. But a blob of some sort drops a key for the parlor. Then Luigi heads for the big, double doors, which is the parlor as he searches for Mario, and is assaulted by a ghost. But the ghost ignores Luigi because it is being sucked by an old man holding a vacuum. But the old man is soon defeated by the ghost. They both leave as three ghosts appear. They both introduce each other. Professor E. Gadd tells Luigi about a man very similar to him without knowing that was Mario, but Luigi tells him that man very similar to him is his twin-brother, Mario and he is missing, so Professor Gadd decides to give Luigi two gadgets so he can be safe and find his brother.
