Luigi and Mario were going at a rather fast pace throughout Treacherous Mansion, Luigi's heart pounding in his ears. Mario panted, falling a tad behind. After capturing the Boo in the Aviation Room, the green clad ghost hunter was now running from room to room with the red clad plumber on his heels. They went to the Nautical Room first and took down a few regular and powerful Slammers. Next, they ran over to the Space Exhibit, using the transport gates. There, they took down a few regular and powerful Greenies. Mario kept tracking the ghosts.

The red clad plumber commented, groaning, "Mamma mia, this is paranormal chaos!"

The ghost researcher stated, "I know, Mario, but we have to do this to help our dimension!"

The green clad ghost hunter yelled, freaking out, "And now is a good time to tell me where to go next!"

Mario checked out the DS and finally replied, "The Ice Age Exhibit is a good idea!"

Luigi nodded as they ran over to the frozen exhibit. After taking care of some powerful Sneakers, they went over to the Jungle Exhibit. It was there they took out a powerful Gobber. The two brothers then went to the Ancient Exhibit where they took some mummies (powerful Greenies in tissue paper). Elvin quickly typed on the computer and reported that the older Manfredi brother should go to the Dark Age Exhibit. Luigi and Mario did just that and took out more powerful Greenies.

After hitting the kitchen (taking out powerful Hiders), Luigi and Mario went to the bathroom (taking out Creepers), they ran to back to the Terrace. Elvin got a strong signal from the Terrance. So Luigi and Mario went there to check it out. And that's when they captured a whole lot of ghosts. Finally, the paranormal levels went down and things were calmer. Mario breathed a sigh of relief as did Luigi. Elvin pixelated Luigi and Mario back to the Bunker as quick as he could.

Elvin commented, "Phew! I didn't think you would make it, boys! But with your brother on the DS and my help, you two were able to defeat all of those ghosts that came out of that porthole! That may have been your toughest challenge so far. Great job capturing those ghosts."

Luigi stated, panting a bit and smiling, "T - thanks Elvin."

Mario went into the kitchen and got Luigi some water as the Poltergust 5000 was emptied. Luigi chugged down the water as Mario chuckled.

The hero of Mushroom Kingdom replied, "That was harder than what I thought it would be."

The green clad ghost hunter responded, "Violet's worth it."

Elvin typed on his computer and told them, "Well, I do have good news. The paranormal porthole is still open! As soon as you both get some more water and food into you, we'll send you two out."

Luigi commented, "Thanks professor."

Mario placed his hand on Luigi's shoulder and told his baby brother, "We'll get her back, Weegie."

Elvin explained, "This is it, boys. It all comes down to this. All paths seem to be pointing to the porthole on the Terrace. The Parascope can't find the Dark Moon piece anywhere. There's no place left for it to be. And the same goes for King Boo... He must be beyond the porthole, still furious that you captured all the ghosts he sent through it! And last but not least, Violet - your girlfriend, Luigi! She's got to be through there too, still in her portrait!"

Luigi responded, "Not if I have anything to say about it."

Elvin nodded as he stated, "I know you want your Violet back. She was rather helpful to you during the first mansion incident. You two are an amazing team, just like you and your brother. So, as I said, this is the moment of truth. And no matter what happens; I just wanted to thank you, Violet, and Mario for everything. I'm proud of you, my boy. ...both of you..."

At this point, both brothers had tears in his eyes. Mario was stunned about Elvin's speech but smiled at his baby brother. He did deserve all of the glory, he was a great ghost hunter and hero, no matter what anyone said about Luigi. Luigi was brave enough to face his fears to save - not only himself but Violet as well. Mario was interested to see what was going to play out in the battle against King Boo. He couldn't wait to help. Elvin was too but he had all the faith in the world in Luigi.

Mario said to Luigi, "You know we got this, baby bro."

Luigi replied, in Italian, "Grazie, grande fratello." [1]

Mario smiled as Elvin pixelated the brothers to the Terrace. Luigi looked at the porthole and thought, 'I'm coming, Vi. I promise that I won't let you down.' As soon as Luigi thought that, he started to get sucked in by a strong wind. Mario felt the strong wind pulling him in as well, his heart pounding in his chest. He didn't know what to expect with this porthole. Once the Manfredi twin brothers got to a mysterious point, it was like a room from out of the haunted mansion from three years ago.

Except it had four suits of armor and one of them was holding the Dark Moon piece. Mario felt something was up. Luigi tried to grab it but was blown away by a possessor ghost. The spirit then split into two and possessed two suits of armor. Mario trapped the two knights of armor on the same rug while Luigi forced the ghost out of the suits by pulling the rug from underneath them. Luigi caught him once but then he broke free and split into three. The possessor ghost then possessed three suits of armor.

The two of them did the same thing again, trapping them all on the same rug and then forcing the possessor ghost out of the suits. Luigi watched in absolute horror when the possessor ghost possessed a giant suit of armor. Mario gasped at the sight as Elvin, whom was watching the fight, turned white as a ghost. The knight started to stop down on the red clad hero but luckily, the green clad ghost hunter quickly pushed him out of the way. Mario breathed a sigh of relief.

"Thanks bro," Mario stated.

"We're gonna need a larger rug," Luigi replied, half joking.

Mario nodded as the two of them tried multiple times to put the two feet on two rugs at the same time. Elvin thought, 'Come on. You two can do it!' After awhile, Luigi captured the possessor ghost and got the last Dark Moon piece. Mario celebrated from the victory as Elvin pixelated them both back to the Bunker... But the only thing that arrived back...was the Dark Moon piece. The ghost researcher felt uneasy and scared. Both Luigi and Mario were gone!
