Luigi followed the crotchety old man through a door into a new lair. All Luigi saw was a bunch of holes with some cover in the ground and some pipes lining the walls. Dirt covered the area and it smelled rather awful. Luigi held his nose shut and spoke a squeaky tone,
"So this is where I'm training? It smells worse than my old apartment!"
"Bah, you'll get used to the stench. I mean heck, I probably reek of this smell anyway," Gadd said as he dragged the Poltergust 3000 behind him to the room.
Luigi notice another object in his hands, some kind of small device like a PDA.
"Hey, what's that doohickey you have?" Luigi pointed to the object in Gadd's hands.
"O yes, this is my other top-of-the-line invention, the Gameboy Horror!"
'The fun never stops…' the green man thought.
"This will help so much more than anything while you're in the mansion. It can show you keys you've found, rooms you've been in, and you can even talk to me from it!"
"How do you have a map of the place if the mansion only appeared a few days ago?"
"…Magic"
"I see… Anyway, is there anything else this thing can do?" as Luigi gently took it from Gadd's grasp.
"Haha, there is more. You can also examine things like holes or paintings and the GBH will reveal any secrets about it!"
"I could see that becoming nifty."
"Now, let's get this training on the move! Strap on the Polergust 3000 and I'll watch you from overhead," Gadd pointed upwards toward a small window, "and I'll talk to you and give you hints through the 'Horror during this training."
"That seems fair enough. What exactly am I training with anyway?"
"Ghosts, what else?" he said while walking out the door to his window retreat.
"Just…peachy," Luigi said sarcastically.

"Alright here's what is going to happen, L," Gadd thought it would be nice to make up a nickname for Luigi so he doesn't have to call him through three syllables each time, "You have to use your flashlight and the Poltergust 3000 as a team to capture ghosts! To fully capture a ghost, here are the basic steps: One; stun a ghost's heart with your flashlight. That means to shine the bugger and reveal its heart, the gateway to getting its soul. Be sure it is within close distance or the poltergeist will disappear. Two; after stunning the ghost, immediately activate the Poltergust 3000's main function: sucking. Suck the ghost hard and make sure he doesn't try and get away. The spook may thrash about wildly; pulling you around the room, but you MUST stand your ground and keep it at bay. If you do that, the ghost will slip right into the Poltergust before you know it."
"...Could you maybe run that by me again, but slower?" Luigi replied sheepishly.
"Suck. Sucking is the key. You must suck the ghost. Suck the life out of it with all your might, that's the way to win. Suck it."
One too many things were going on in Luigi's skull.
"Anyway, just shine your torch on the ghost and start the Poltergust 3000 up. And don't forget to keep your stance and not let the energy of the situation take over you. Good luck," Gadd waved at Luigi through the screen.
The room plunged into darkness and all Luigi could see was black. He waited for something to happen, but nothing did. A few seconds later, Luigi thought the old man feel asleep on the dashboard in his windowed room above him and forgot about the training. As those thoughts passed through the green man's brain a faint click could be heard and a loud rumble ensued. Though Luigi couldn't really see anything, so he assumed I was coming from one of those holes in the ground.
Luigi saw a cloud of dust raise from the midst of the room and heard various machinery power up.
"Bah, this'll only be slow for this one door. The training room hasn't been used in years!" Gadd laughed to Luigi through the Gameboy Horror. Though, Luigi was too preoccupied with what was going on to hear the scientist.
Suddenly, a loud scream came from that dust cloud and there floated a similar ghost that tried to get Luigi beforehand.
"O GOD NO I DON'T WANT TO DIE! PLEASE MAKE IT GO AWAY!" Luigi curled up into a ball and held his legs close as the orange entity started creeping its way towards him.
"LUIGI! Get 'ahold of yourself! These are just training ghosts! I've rid them of evil thoughts and they are just here to help you! Now be nice a say 'Hi' to Frank!"
Luigi stumbled to get back on his feet and fixed his eyes on the glowing figure.
"He-he-hello, Frank?" Luigi said stepping backwards to the wall.
The ghost wore a smile on its face and simply waved back.
"Now then Luigi," Gadd said through the Gameboy Horror, "Are you ready to start your training?"
"…"
"Luigi, are still alive down there?"
"…"
"Come on! Frank just wants to be your friend!"
"…"
"Luigi?..."
"..a-a-ok," Luigi coughed up into the Gameboy Horror's microphone.
"Good! Now then, Frank isn't gonna hurt 'cha. Just approach him, shine your flashlight, and activate the Poltergust 3000!"
Luigi slowly stepped towards Frank. He pulled out his flashlight from his back pocket and it was immediately absorbed by the Poltergust 3000's nozzle, which was dangling next to him.
"E-GADD! What the heck just happened?!"
"O yes, I forgot to inform you that the Poltergust 3000 will try and make your life easier at every turn. It absorbs things you'll need to switch to often and such."
"Well then how the heck am I supposed to use my flashlight?!"
Frank was beginning to float around the room in boredom.
"All you have to do, Luigi, is think. Just think about using your flashlight and it'll work just fine," the Professor replied.
"Alright, let's try this…" Luigi thought about using his flashlight.
Like magic, the nozzle of the Poltergust 3000 transformed into his old flashlight,
"Now you got it, boy! Soon you'll be controlling the elements!" Gadd said with a smile. 'Like that'd ever be possible though…' he then thought.
Luigi kept thinking about using his flashlight, then using the Poltergust 3000, and then back to his flashlight. He finally got the hang of it and was ready for anything, seemingly. Frank on the other hand was still aimlessly floating about the room, not giving a care to anything. Luigi tried to get his attention by throwing some dirt at him, but that failed as it went straight through him.
'OK Luigi, you just need to capture this ghost's attention, not its soul. It should be easy' the green man thought to himself.
Some attempts later, from throwing God knows what to pounding the wall with his fist, Luigi was becoming tired. Frank was still isolated from the rest of the world as the wonderment of bricks underground intrigued him. Luigi then gave one more try,
"Hey, FRANK!"
Frank turned around with the same jolly smirk on his face and waved to Luigi.
'Why the heck didn't I think of that earlier?...' Luigi sighed to himself.
"And now, the training begins!" Gadd shouted from the plastic in Luigi's hand.
Frank floated back down from the ceiling and made his way in front of Luigi. Luigi was still a bit timid and slowly backed up from Frank. The orange ghost still wore the same large smile plastered on his face, showing no harm at all was meant.
'Ok, just gotta think; here goes…' Luigi thought about using his flashlight.
A ray of light came out from his hand and his flashlight instantly appeared. The bright light landed right on Franks face, and he was stunned. His heart was showing and was ready for capture.
'Now, Poltergust!' Luigi thought to himself.
The suction was being thrown and Frank was immediately trapped by the Poltergust 3000's power. Frank cried out in pain as his soul was being drained into the vacuum pack. Luigi was standing his ground against Frank, believing he had finally overcome his fear of ghosts. Then Frank lunged backwards over top of Luigi and the green man yelled in fear and fell to the ground shaking. His hands were over his head and knees drawn close, hoping Frank wasn't going to try and kill him.
"Luigi! You almost caught Frank all by yourself! You have to get over this fear of ghosts if you ever want to help your brother!" Gadd said from the Gameboy Horror that was thrown to the left of Luigi.
Frank had disappeared from the room after being ripped away from the Poltergust 3000's suction. Luigi got up and held onto himself and peered around the room wildly, making sure he was fine and alone.
'I've just got to face my fears if I ever want to save Mario from that mansion,' he thought to himself while picking up the Gameboy Horror that he dropped.
"Alright L, now that your senses are back, let's wait for Frank to come back. He may creep up on you if you're not too careful," Gadd said through the speaker.
'Flashlight!' Luigi thought to himself and brought his flashlight to existence in his hands.
He looked around the room and waited for Frank to make his reappearance. Smoke started manifesting behind Luigi, without Luigi himself realizing it.
"BAAAHHHHHHH!!" came from Frank who appeared behind Luigi.
"EEEEEAAAAAAAAAAAHHHHHHHHHHHHHH!!!" Luigi threw his hands in the air and then fell on his rear. He turned around and began scrambling backwards on his hands and knees toward the wall.
"It's only Frank, he's your friend; you can do it," Luigi said to himself as he got up to calm down from the scare attack, 'Flashlight!'
The beam landed right on Frank and Luigi started up the Poltergust 3000. Frank let out yet another scream in pain from his soul being slowly ripped from him down into the depths of the über vacuum cleaner. After a few seconds, Frank twisted right down into the tube and into the storage of the Poltergust 3000.
"I...I did it! Wahoo!" Luigi said triumphantly, giving the peace sign (even though no one was around to really see it).
"Ready for more?" Gadd snickered.
"O crap…" Luigi frightfully spoke.
