"Phew... that was quite some struggle you put up there, big guy... but in the end, it looks like victory's for the little guy." Professor E. Gadd a ghost hunter and scientist said to the now struggling ghost inside the compartment of his latest invention, the Poltergust 3000, a special vacuum cleaner with the ability to capture ghosts, as he began to walk back to his lab in Boo Woods, completely unaware of a glowing pair of red eyes watching him in anger.

The one who was watching the doctor leave was none other than King Boo, the king and leader of the Boos under his control saw what has become of one of his most mightiest Boos in his army and he was furious and vowed revenge for this humiliating blow to his army.

Meanwhile, E. Gadd made it to his laboratory and looked at another one of his inventions, a special machine that had the power to turn any ghosts trapped within the Poltergust 3000 into paint portraits. The process was simple all would do was connect his Poltergust 3000 to a metal lip, then the blue section of the machine separates the common ghosts from the portrait ghosts, then machine then finishes it's process by resizing, squashing, and finally framing the ghosts. The portraits are then dispensed from the end of the machine, fully able to be hung in the gallery for later viewing. Once the process was finished he looked at his new Boolossus painting with pride as he had just hung it up upon his gallery wall feeling tired from the hard fought battle, then retired to his bed to get a good night sleep.

Meanwhile, back with King Boo, he was planning the perfect revenge against the professor for Boolossus and then a Boo suddenly appeared and whispered something to the king and then the king then began to have a fanged grin on his face as he listened, "Gather all of the Boos available... we leave for E. Gadd's lab immediately..."

Professor E. Gadd was sleeping peacefully until he began to heard many noises and sounds until he heard the door leading to his lab suddenly burst wide open and then heard the sounds of many Boos laughing and ran to his lab and to his shock and horror h saw King Boo and his army of Boos raid his gallery and taking the portraits off the walls including the portrait of Boolossus and a strange ghost named Bogmire, then he saw King Boo flip the switch of the Ghost Portrificationizer to reverse and the Boos all placed the portraits into the machine and watched in horror as all of the ghosts that he captured were fully unleashed and were now fleeing from the lab and with their work finished the Boos all followed the released ghosts and ran after them and then he suddenly felt the ground tremble as a sinister looking mansion suddenly appeared and right in front of the entrance of his lab and then he saw all of the freed ghosts enter the mansion to hide.

Inside the Mansion, King Boo told all of the Boos that this was all just phase one of his plan as he wanted to make some portraits of his own, but with people and he also had just two in mind to begin his collection... the Mario brothers. So he had one Boo make a false letter telling Luigi that he won this mansion in a contest and sent him a map to lead him to the location and he knew that he and Mario would come together and that's when they'll capture them and then after the brothers were out of the way, he would then add the princess to his collection and everyone of their friends and then... then they would capture the professor for the last portrait to show him how it feels to become a mere painting to be put on display and to be humiliated by what he has been hunting for years!

When the Boo finished the letter, he had the Boo send the letter to Mario and Luigi's mailbox and all they had to now... was wait...

The Boo that was to deliver the bait letter to the home of the Mario Brothers sneaked through Toad Town, invisible.

Ah...there was the post office! Would be too much of a give-away if the Boo delivered the notice, so why not make it come from an unknowing a?

Floating through the wall, the spirit remained unseen and stopped, gawking at the scene of the postmaster shouting at a Paratroopa with a mail satchel.

"THAT IS IT PARAKARRY! THIS IS THE VERY LAST TIME YOU SCREWED UP ANOTHER DELIVERY! YOU'RE FIIIIIIRRRREEEED!" The Toad Town Postmaster yelled at the shaking paratroopa.

"B- But..." Parakarry attempted to speak, but was then interrupted by his boss.

"No! I don't want to hear your pathetic excuses, I want you to pack up and get out of my office and out of my mail service! You're clumsy and often loses the letters you're supposed to deliver, and you're slow at delivering mail, and all of it put together has caused you to loose pieces of undelivered mail scattered across the entire Mushroom Kingdom! So you're out of here! And before you even say that "I'm the ONLY mail carrier who can make far-away deliveries." line...well, let me show you your official replacement... Follow me."

The postmaster and Parakarry went to the mailing room and Parakarry was confused as there was no other mail carriers around in the room and then saw a only a door in the wall. The postmaster then turned to Parkarry and said, "I can't say that I blame for your confusion, Paracarry, but just watch this..." the Postmaster then picked up a card that had a picture of Princess Daisy and then picked up some mail for her and then swiped the card in a card scanner near the door and Parakarry saw a light glow above the door and then the postmaster opened the door and much to Parakarry's shock and amazement, saw Princess Daisy's mail box just on the other side of the door and the postmaster simply placed the mail in the mailbox and closed the door.

"You see Parakarry, this door is magical as all it needs is a simple swipe of a card with the address and presto! Simply place the mail in the mailbox! So as you can see, ANYONE can and WILL do your job better than you! Now then, I want you and your things gone by closing time or I will have you arrested... Good day." And with that, the postmaster left his EX-employee alone with the door.

Angry at this stupid door, Parakarry suddenly attacked the door's controls and with a huff, the flying koopa turned and left, leaving the Boo alone as it became visible again.

"Instant mail, huh? That'll make this easy!" The ghost grinned, then swiped a picture of Luigi before opening the door and stuffed the fake letter in, unaware that the door suddenly locked on someone's home...someone who did NOT live in the mushroom kingdom...

Hearing the door go off, the postmaster entered, the Boo going invisible just in time to avoid him, and frowned.

Seeing the door active, the postmaster frowned and checked the controls. "Huh? Oh, just great...the door's control station is messed up! Went to the wrong address...that fink Parakarry, no doubt...now, I need to get the recall system running.." the postmaster grumbled furiously.

"Oh no..." the Boo said, going as pale as an already invisible ghost could.

Wrong address?! The king was NOT going to like this!

"What do you mean the Mario brothers didn't get it?!" King Boo raged.

"A ghost couldn't deliver it without giving it away that it was a trap, so it had to be sent by Toad Town post, but the mail screwed up, your frightfulness! The mansion notice went to someone else!" The Boo coward.

"SOMEONE ELSE?! WHO?!"

Naruto yawned as he got home to his apartment from his first ever solo mission, the mission itself was nothing too big, as all he had to do was clear out a bandit camp and with the use of the shadow clone jutsu, it was all a piece of cake.

As he entered the place he lived in, the fifteen-year-old flicked the light switch, only for nothing to happen. Doing it a few more times, he frowned as he remembered something.

"Oh great...landlord quadruples my rent yesterday and shortens the rent payment deadline to today, then shuts off my heat, water, and electricity...man, why do I have to pay for the entire place when I'm the only resident?" grumbled the whiskered blond.

He REALLY needed his own place...

Opening the blinds to let sunlight it, the teen frowned, seeing an envelope on the floor. Probably his eviction notice...

Picking it up, opening it up, and finding a notice inside like he figured, he blinked. Huh? He won? Won what? He hadn't entered any thing...

Looking over the notice, he felt his eyes widen. Was this a joke?! He needed to figure this out. Good thing his friends were smart.

Exiting the apartment and going through Konoha, Naruto soon found all of his friends at the Yakiniku Q, the village's Gyū-Kaku-style yakiniku restaurant (should have been Ichiraku Raman in Naruto's opinion).

"Hey guys! You're never going to believe this!" he placed the winner's notice on the table and Shikamaru, who muttered something about "Troublesome whiskered blondes", picked up the notice and soon found that he was now crowded by his friends as they wanted to see what Naruto was so hyper about and as they all read the paper, each of their eyes began to widen as the what they were reading began to settle in.

They all turned to Naruto and Shikamaru only had this to say, "Troublesome..."

"What the?! YOU won a mansion?!" Sakura gawked.

"Party at Naruto's new place!" Kiba cheered.

"That's just it...I DIDN'T enter any contests!" Naruto complained.

After Naruto said that, a strange door suddenly appeared behind them with a white glowing light.

Everyone stared, then gave Naruto an expectant look.

"What?! Why do I have to check it?!" he said.

Sakura grabbed him by the collar and threw him at it with a crash.

"Ooowww! What'd you do that for!?"

"Just open it!" The medic demanded.

With a sigh, Naruto went to the door he opened it and saw that the door lead to...nothing. Just darkness. Shrugging, Naruto was about to close the door when suddenly a powerful, vacuum like wind began to suck up all of his friends one by one and Naruto tried to grab them to save them but he was too late as Hinata was the last one to get sucked in and not wanting to leave his friends in trouble, Naruto then jumped into the door with the door closing itself and suddenly vanished as if it was never there...

Waking up, Naruto groaned, "Ughhh...ok...what was that?" He found himself thrown laying in the middle of a dirt road just as he heard the door close itself behind him. Naruto picked his head up and turned around, saw a dead tree with the door on it, but it had no handle, so it looked like he couldn't go back the way he came.

Then his eyes widened as the memory struck him.

Sakura, Sai...Shikamaru, Ino, Choji...Neji, Tenten, Lee...Kiba, Akamaru, Shino, Hinata...they'd all been pulled into the door with him!

Naruto wouldn't go back... not without ALL of his friends! Bolting to his feet, he looked around the dead, night-enshrouded forest, but saw no sign of his friends.

Gritting his teeth, Naruto turned to follow the trail of the dark forest, figuring if there was no way back, he could only move forward if he wanted to find everyone. Listing to the crows cawing as he walked he didn't notice two crows were watching over him, one crow looked angered while it's companion looked sad for the wandering Uzumaki.

Naruto then saw where the trail ended, and to say that he was surprised would be like saying that Jirayra was in love with Tsunade's breast was an understatement.

A house...a huge one! Looking up at it, the whiskered boy saw a big, creepy mansion in the heart of the dark forest. It looked like it has three floors from the sheer size alone and Naruto kept getting a creepy vibe from the two angry eye shaped windows as if the house was angry about something.

Then Naruto saw the gate suddenly open for him, as if in welcome...as if he were expected...Wait...was this the mansion from the notice?! His jaw dropped. The so-called "mansion" being a run-down place was shocking. And it looked more like a haunted house!

It was an unpleasant surprise to be sure...But then, Naruto wasn't afraid of surprises, hell, he wasn't really afraid of anything really – that is, if you didn't count his phobia of ghosts (What? Years of growing up alone in a small and old apartment, as well as a lack of parental love and/or protection from such 'terrors' had done well to turn what was a childish fear into a very paralyzing phobia. Was it embarrassing? Yes. Did Naruto really care? No. He was brown-pants-required afraid of ghosts, and while he had accepted it, it still didn't change the fact that he couldn't punch a ghost square in the face.)

With a sigh, he figured he might as well check for his friends in there. A run-down building was better than wandering around these creepy woods. And if his friends were as lost as he was, they'd at least come to the same conclusion.

Naruto looked around the room looking over everything, so he wouldn't miss any signs if the rest of his friends were here, the thundering sky would occasionally light up the room as he walked around. Checking all the doors, Naruto frowned.

Locked. Each and every one of them.

"Well...that settles that...I'm the only one here..." the orange and black wearing young man sighed. Then he heard something and froze as he saw a strange, orange-colored cloud, it also seemed to have a key inside of it.

Naruto's eyes widened as he saw the key float around the room before the orange cloud seemed to fly through the wall leading towards a room on the second floor, but the key fell out of the cloud and landed right into the middle of the floor at Naruto's feet.

'Hope it wasn't a g-ghost...' Naruto thought with a small shudder. It was one thing for this place just to look spooky...but to actually be HAUNTED...!

Out of a need to distance himself from that thought alone, he turned his attention to the key and picked it up.

Hmm...

Checking to see which lock the key fit the door of, the Uzumaki made his way through the Foyer back up to the parlor. Maybe he could actually get to the other rooms, now. Making his way to the second floor, the blond tried the key and was rewarded when the central door of the second floor opened and he entered the room.

However, seconds later, a loud screech made from an orange colored ghost caused Naruto to scream in absolute horror as he fell on to his butt as he tried to back away nearly froze on the spot at the sight of it.

'G-Ghost!'

The strange spirit grinned hugely, drawing ever nearer to him. Ghosts! Why, oh why, did it have to be ghosts! They were Just. So. Creepy!

"Geh!" Naruto made a squelching sound as the spook drifted even closer to him, floating impossibly just above the ground, as if it weighed little or next to nothing. His usual self-confidence abandoned him in the wake of what he'd seen. Then everything went black...

Seeing the reaction from the boy, the ghost hooted with delight until it was caught in what seemed to be a gust of wind and started trying to fight against it, the gust lead to an elderly old man who had...a vacuum cleaner on his back of all things!? Either way it looked like it was working as the ghost attempted to escape the suction, dragging the old man on the floor then before the old man knew it, the ghost then turned around and sucker punched the old man, knocking him onto his rear.

The ghost then laughed at the old man's pain in triumph before disappearing from sight.

"Ouch... Ooof... I sure take a lot of knocks in this line of work." The old man stood up dusting himself off, "I'm getting too old for this ghost-catching tomfollery."

Then the old man turned to Naruto, "Anyway, nice to meet you. I'm Professor...Oh...that's not pleasant..."

The boy had fainted, turned pale as a sheet, his eyes were bulging in his head, he was sweating, crying, and foaming at the mouth all at once. Not to mention his pants reeked from the back and he was slumped in a puddle of his own urien.

The old man sighed. Oh boy...

The first thing Naruto registered was the sound of a washing machine...odd. Then when something hit his face his eyes opened and he went red.

Who had taken his pants?!

Those were the object tossed on his head.

"Ahh...Good to see that you are awake my dear boy, I was afraid I might've lost you there. Welcome to the lab." a voice said with a chuckle.

Pulling his pants off his head and slipping them back onto his lower body, Naruto looked to see an old man with a round shaped head, a small button nose and was wearing glasses that prevented Naruto from seeing his actual eyes. The old man had a friendly open mouth smile that showed his single tooth, with a large strand of white hair on top of his bald head. He also wore a lab coat and wore black pants with brown shoes.

Looking at him made Naruto think of an onion.

"Please allow me to introduce myself, I'm Professor E. Gadd, but you can just call me Gadd for short. Hahaha. Glad to see you're up. Ghost gave you a fright, eh?"

Naruto paled. That was right...the ghost! He'd lost it when he saw the ghost!

"What's a young feller like you doing around here, anyhoo?" The old man asked, breaking Naruto from his thoughts of the ghost.

"Oh...well, you see, Old Man Gadd, may name's Naruto Uzumaki, and I don't know how or why, but I won this mansion in some contest I didn't even enter and apparently my friends and me were all brought here..." Naruto said, then started telling the professor all about what happened.

Once Naruto finished, the old man then began to think to himself, "My dear boy, I believe I've seen all of your friends, and they are inside that mansion. And apparently this "Contest" that you won that mansion in was all a trap; for that mansion appeared shortly after about a week ago and after my gallery has been raided..."

"Gallery?" Naruto wondered.

Gadd nodded, "My gallery of ghost portraits..." he said, missing Naruto paling again. "Seems we need to deal with the ghosts. Luckily, I invented just the thing: a special backpack vacuum cleaner engineered to catch ghosts. It's the only way to foil 'em! This is the only thing they fear! I call it the Poltergust 3000! But I'm getting too old for this ghost-catching tomfoolery...good thing you're here, eh?"

"M-m-ME?!" Naruto sputtered, looking at the professor as if he'd utterly lost his mind.

"Well, youngster...seems you have a choice here, but seems you need to make up your mind..."

"I have! I'm outta here!" The blond yelped, then bolted in the direction of the door.

"Well...what scares you more: ghosts, or letting something happen to your friends?"

The words froze Naruto in place. What scared him more?

Naruto bit his lip, he hated ghosts, but if anything happened to his friends, his precious people, all because he ran... Naruto winced as he realized he'd be alone again...only this time, he'd deserve it, the price on his cowardice. The people he cared about were his life, protecting them was his purpose. If he ran and abandoned them...

With a sigh, he turned back to Professor E Gadd, his body trembling all over, but his gaze was firm.

"Gadd, for the record, I'm scared shitless...but gemmie that ghost vacuum!"
