NOTE: The original Luigi's Mansion game in this story took place two years before Dark Moon game.

It was a beautiful day in Mushroom Kingdom. The sun was hanging high as the birds flew across the blue sky. An Italian man wearing a green long sleeved dress shirt, blue overalls, brown shoes, and a green hat with a "L" on it. He had short brown hair, blue eyes, and a small black mustache. His name was Luigi Manfredi, the younger brother of Mario Manfredi, the hero of Mushroom Kingdom. Mario had it all...even the princess of Mushroom Kingdom, Peach. Luigi was watching television in his chair. That's when he heard barking from outside.

Luigi was living in the big mansion for quite sometime now and even though it was a bit away ways from the kingdom, he could go into town with a matter of minutes in case he was needed. Luigi looked outside and saw his puppy in the front yard. But not just any puppy. This puppy was a ghost from Evershade Valley, where Professor E Gadd was studying ghosts but that was another story for the moment. The professor called him Polterpup and the name just stuck. The green hated plumber looked outside and saw Polterpup.

"What is it boy," Luigi asked.

Polterpup pointed as Luigi saw someone coming up the walkway. It was a red color. 'Mario,' Luigi thought.

Luigi turned to Polterpup and said, "Quick, out of sight!"

Polterpup obliged as it disappeared. Luigi quickly grabbed a gardening shovel - to make it look like it had been planning a garden. The reason he was hiding Polterpup was also another story. Like Luigi anticipated, Mario was coming through the front gates. Mario was wearing a red long sleeved dress shirt, blue overalls, brown shoes, and a red hat with a "M" on it. He also had short brown hair, blue eyes, and a big black mustache. Even though Mario was older, Luigi was slightly taller.

"Planting a garden," Mario asked, slightly amused.

Luigi shrugged as he answered, "Yeah but apparently, I'm no good at it."

Mario laughed at this and turned sad.

Mario started to ask, "Luigi...are you...?"

Luigi looked at Mario as he twirled around his fingers nervously.

"Really leaving," Luigi finished, noticing that Mario didn't want to finish his question. Mario nodded sadly as Luigi sighed and approached his older brother. He placed a hand on his shoulder, rather gently. "It's time I head out on my own," Luigi answered, cryptically.

Mario hung his head as he asked, "When will you be back?"

"Probably never," Luigi barely answered.

The red hatted plumber looked up at Luigi, in shock. Did he say 'probably never'? Apparently, he did as Luigi wasn't looking Mario in the eye.

Mario finally asked, "What, why?"

Luigi sighed as he answered, carefully, "You belong here. You have the princess of the kingdom. What do I have? This mansion...that's it. Daisy is too far away, ruling Sarasaland. So, I'm leaving by the end of this week."

Mario was too stunned by this to say anything else and by the time he could think of something, he heard a scream. Mario and Luigi both sighed, knowing that this meant trouble.

"Looks like duty calls," Mario said, pushing this unhappy business aside.

Luigi stated, "You go on ahead, I'll catch up."

Mario nodded as he went ahead and once he was out of earshot, Polterpup appeared next to Luigi. The ghost pup whined, obviously upset that his master had to keep him hidden from Mario.

Luigi scratched Polterpup on top of his head and said, "Don't worry, boy. You won't have to hide from anyone here anymore after Mario and I save Princess Peach...again."

Polterpup wagged his tail and licked Luigi's face, as if to say 'good luck'. With that, Luigi left.

-Flashback: 6 days ago-

Professor E Gadd (who was an old man with one strand of white hair, one tooth, swirling glasses, wearing a lab coat, a red undershirt, blue jeans, and brown shoes) finally managed to find where King Boo was hiding out with the last piece of the Dark Moon...and the painting of Mario. Just recently, King Boo had returned to seek revenge on Luigi and the professor. That's when he grabbed Mario and entrapped him in a painting again. Luigi had just defeated the King Boo and took the last piece of the Dark Moon.

Luigi celebrated and the illusion faded into where the shrine was. Luigi looked around, scared. That's when he saw the painting of Mario. Luigi ran over to it, his heart pounding in his chest. Mario needed to be free so he could continue being the Mushroom Kingdom's hero.

"Mario," Luigi asked, knocking on the painting.

Luigi was so upset by this that he didn't even noticed that Professor E Gadd pixelated himself in. The professor placed his hand on Luigi's shoulder and pointed at Luigi's Dark Light device. Luigi smiled as he shined it on the painting, making Mario return to normal. Mario smiled at his brother and shook his hand, thanking Luigi for saving his life. Luigi smiled simply, a lot on his mind and heart. The toads that were working for the professor were also pixelated in, holding the other pieces of the Dark Moon.

Luigi went over to them as Mario and Professor E Gadd watched. The Dark Moon fixed itself magically, sending out a pulse to settle down all of the ghosts. Mario came over to Luigi and looked up. Mario was proud of Luigi, he truly was a hero. After Professor E Gadd released all of the ghosts that Luigi caught, they celebrated with the professor, Mario, and the Toads. Polterpup - who had also returned to normal - walked over to Luigi, sadly. The ghost pup obviously felt bad for all that it did while the Dark Moon was out of the sky.

Polterpup looked at Luigi with sad eyes. No longer afraid of the ghost pup, he waved to him.

"Hey doggie," said Luigi.

Polterpup jumped up into Luigi's arms, happily. Polterpup licked Luigi a few times, making the green hatted plumber smile.

"That's my bro," Mario stated, proudly.

Luigi blushed - a little embarrassed as a greenie ghost took their picture. After the flash, Mario fainted.

"Mario," Luigi cried out, worried.

Professor E Gadd was the first to Mario's side as he stated, "Goodness, we better get him back to the lab!"

Luigi nodded as Polterpup whined. Even though the ghost pup didn't really know Mario that well, he was still important to Luigi...

A few hours later, Luigi was at Professor E Gadd's mansion. The ghosts all looked worried as did Polterpup. Luigi was the most worried. He had to write to the princess that everything was okay, leaving out the details of what happened and reassured that Mario and he would return in a few days. Finally, Professor E Gadd stepped out of his room.

"How is he, Professor," Luigi asked, worried.

"He lost his memory again," Professor E Gadd answered, shaking his head.

Luigi sighed, relieved, surprising the professor.

The professor asked, "Why are you breathing a sigh of relief?"

Luigi answered, "Truthfully, I wanted Mario to forget this so I can leave Mushroom Kingdom. I would like to be your partner. I have no reason to return to Mushroom Kingdom, I'm not the hero there. Mario is."

Polterpup whined sadly as Professor E Gadd thought it over.

He answered, "Alright my boy. You can be my partner."

Luigi smiled as he pumped his fist in the air, victorious. He was going to be the best partner and ghost catcher.
