In the skies located in Equestria, there were three female purple ghosts wearing magician uniforms and hats seen hovering in the air after being dispatched by their commander King Boo, the three ghosts names are Nikki, Lindsey and Ginny. They're magician ghosts sisters from the eleventh floor of the hotel who are sent to search for a luxurious city filled with many ponies called Zephyr Heights according to the unicorn named Alphabittle who King Boo trapped in a portrait.

"Man, where is this Zephyr Heights?" Lindsey asked while looking around the area.

"I don't know Lindsey, this obligation is quite difficult when you don't know the exact location of this city." Ginny told her with an aggravated expression. "If only that coward of a unicorn spoke in a more specific tone!" She exclaimed.

"Hey sisters, I see something in the distance." Nikki told them as he pointed to somewhere.

Both Lindsey and Ginny hovered their sisters' location after hearing her saying that she has discovered something in the distance from where she is hovering. When they both got to her, they looked at where she is pointing and saw a city made of gold along with some electronics and other walk paths.

"Huh, would you look at that, we found a city." Ginny said with a nonplussed expression. "Do you think that this city matches the description of what that unicorn delineated about?" She asked her sisters.

"Possibly, since he did say something about the city being very luxurious, and this city does seem luxurious to me." Lindsey replied.

"Well what are we waiting for then? Let's go attack this city and capture many of the ponies residing there under the commands of King Boo and Hellen Gravely." Nikki said with a wicked smile.

The other two sisters nodded in unison after being reminded of their primary objective ordered by King Boo. So, the sisters all hovered their way to Zephyr Heights in preparations of invading and preoccupying the ponies for the ghost King.

On a dirt track that leads straight back to Maretime Bay, Sunny Starscout, Hitch Trailblazer, Izzy Moonbow, Pipp Petals and Zipp Storm as well as Hitch and Sunny's son Chase were all seen leading Luigi and his polterpup companion back to the Crystal Brighthouse where he will be questioned by them all on who and what he is as well as why he is here.

When the mane five all arrived at the cafe after Luigi, Chase and Polterpup rescued the ponies from the three Goob ghosts, they all viewed Luigi and his companion as threats to the society as well as mistaking him to be the attacker of the ponies of Bridlewood but luckily, Chase managed to stop his parents and aunts from subduing Luigi and talked them out by playing that he is a pacific being and is not seeking to menace any ponies and it were the three ghosts who attacked the ponies.

The mane five were all sceptical of Chase's claim due to them thinking that ghosts are just from horror stories and movies but, that transparent dog is another story so, they all decided to lead Luigi back to the Crystal Brighthouse for further interrogation that they have in their minds.

During the walk, Zipp was seen hovering behind Luigi and his weird transparent dog to detect for any escape attempts which made the plumber anxious of how stern this pegasus looks.

"Sorry about this Luigi. My parents and my aunts must always interrogate any unknown species in Equestria for the safety of everypony." Chase apologized in a sorrowful tone.

"It's okay Chase, I understand that." Luigi accepted Chase's apology with a nod.

Once both Sunny and Hitch made it to the front doors of the Crystal Brighthouse. They both pushed the door opened and walked inside along with Izzy, Pipp, Chase, Luigi, Polterpup and Zipp Storm. After that, the pegasus princess immediately shut the doors behind her so that the creature and his pet wouldn't escape.

"Alright creature, we've specifically brought you here for an interrogation." Hitch told Luigi with a stern expression. "You will answer our inquiries whether you like it or not, if we catch you trying to escape, I will hunt you down and throw you into a prison cell in my sheriff's station. Do I make myself clear?" He warned him which made Luigi swallow a lump.

"S-sure." Luigi replied with an anxious nod.

"Perfect. Now, let's take it over at the dinning table over there." Hitch told him as he pointed to the dinning table. "Chase, go grab my pencil and my notebook." He ordered.

"Yes father!" Chase said as he ran to get his dad's notebook and pencil.

During that, Sunny, Hitch, Izzy, Pipp and Zipp all lead Luigi and Polterpup to the dinning table where they will interrogate the plumber. Once they all got to the table, the ponies all sat on their chairs with both Luigi and Polterpup sitting on spare ones. When Polterpup saw sweets on the table, he locked his lips before munching down on their and barking happily.

"Aww, what a cute little doggy." Izzy cooed, she has never seen such a cutie like him before.

"Don't forget what we're here for Izzy." Zipp reminded her.

"Oh right."

"Here are your notebook and pencil as you requested dad." Chase said as he gave his father Hitch a notebook and a pencil.

"Thanks son." Hitch said patting Chase on his head gently. After that, he looked at the creature known as Luigi. "Alright now sir, I'm gonna ask you questions now, are you ready or not?" He asked.

"Sure, anytime." Luigi replied with a nod.

"Good, and to have some manners my name is Hitch Trailblazer, the sheriff of Maretime Bay, this is my wife Sunny Starscout, this here is our son Chase Trailblazer, this over there is Izzy Moonbow, a unicorn from Bridlewood, and these two are Pipp and Zipp, sister pegasus princesses from Zephyr Heights." He introduced everypony.

Luigi was perplexed by those names as well as hearing that there are royals as well in Equestria but, he disregarded that thought and prepared to get interrogated.

"Alright, here's my first inquiry, what is your name?"

"My name is a Luigi sir."

"Luigi? Why that's an odd name." Hitch commented with a raise of his eyebrow. "Nevermind that, second question, what kind of creature are you?" He asked.

"I am a human being." He replied which got the mane five confused.

"Mind delineating what your species are exactly?"

"No sorry, it's complicated."

"Okay, I can respect that." Hitch said with a shrug. "Here's my third question, where are you from?" He asked.

"I'm a from the mushroom Kingdom, a Kingdom inhabited with human beings such as me and mushroom people called Toads. The Kingdom is ruled by a princess named Peach." Luigi replied.

The mane five were both perplexed and nonplussed at Luigi's reply. Just what are these mushroom people? And what is this Kingdom that he resides in? He has a princess ruler too?

"Whoa a princess, can she fly?" Izzy asked with an exhilarated expression.

"Well, not exactly, she is more of a royal with no special abilities." Luigi corrected her. "Anything else?" He asked Hitch.

"Okay fourth question, what is that dog next to you?"

"Him? This may surprise you Hitch but, he is no ordinary dog, he is actually a ghost." Luigi replied. "His name is polterpup and I met him in the Evershade valley." He finished.

The mane five were all horrified and startled to hear Luigi saying that the dog is a ghost, if that is true then that means that it must has the unique abilities to phase through solid objects such as walls. But, Hitch pushed the anxiety out of him before resuming the questioning process.

"That's interesting. Anyways, next question, what is that vacuum that you wear on your back?"

"Oh, this here is no ordinary vacuum, it's called the Poltergust G-00. It has the ability to capture ghosts." Luigi replied which made the mane five surprised.

"Whoa, it can capture ghosts?" Zipp asked with an astonished expression.

"Correct Zipp, this vacuum is the modified version of the previous Poltergust 5000 that my good friend professor E Gadd invented for me. It has many features such as a strolbulb which is use to stun ghosts before vacuuming them up, a dark light which is used to reveal hidden objects that are concealed, suction shot, super suction, burst, blow and many more." Luigi delineated which made the mane five flabbergasted at this technology. "It also has this latest feature." He told them as he pressed a button on his vacuum which made the mane five perplexed again.

Then, the five ponies noticed the slimy area held in a glass container in Luigi's vacuum beginning to flow out of it. A brief second later, a slimy being that looks as interchangeable to Luigi appeared out of it.

"Ah, there he is again." Chase said with a smile.

"Whoa! Who is this individual?" Zipp asked as she hovered over to the slimy creature and touched its nose to see that it is quite bouncy like jelly.

"Awesome, is it made out of slime?" Izzy asked with a wide smile.

"Amazing, just what is that thing Luigi?" Sunny asked.

"This ponies is known as Gooigi, he the professor's latest invention for me, he serves as my personal assistant in tight situations where I cannot handle things on my own. He is extremely malleable and can slip through tight spaces such as grates or vents." Luigi delineated which made the mane five amazed.

"Wow, this professor of yours must be a genius to invent advanced technologies like this." Chase commented with an impressed smile.

"Indeed Chase." Luigi said with a nod. "However, Gooigi here has some disadvantages of his own as well." He told them which got the mane five including Chase surprised.

"Huh? And what's that?"

"Gooigi is not remotely waterproof meaning that he is susceptible to water due to him being made of slime so, if he touches wet objects such as water, he will melt and return to his container." He informed them.

The mane five and Chase were all amazed by all of this new information that Luigi issued to them starting form: his species, the Kingdom that he resides in, the Poltergust-G-00 and its features, his polterpup friend, and Gooigi. These were amazing new stuffs that they were comprehending!

"Wow, now that is so cool!" Pipp exclaimed taking pictures of Gooigi as he only gave a thumbs up.

"Indeed he is miss Pipp." Luigi said with a nod before returning Gooigi in his container. After that, he looked back at Hitch. "Anything else?" He asked.

"Okay, here is my last question, what happened in Bridlewood?" He asked, and Luigi must assume that he was referring to the horrific event that had occured in that village between, him, Chase and fhe three ghosts.

"Oh, here's what has happened. Me and Chase were following Polterpup to somewhere when he sniffed out something in the distance and he lead us to a village called Bridlewood in the end. We followed him into a cafe where there were more of these mares and stallions being preoccupied by three ghosts known as Goobs, and to my assumption, they're all under the command of my enemy King Boo." He told them which got the mane five and Chase perplexed.

"Can you fill us the details of this enemy King of yours please Luigi?" Chase asked.

"Sure thing Chase. King Boo is a ghost King who I encountered years ago back when I won a mansion in a contest that I did not enter, he is also my arch nemesis. He has a very wicked ambition of trapping individuals inside of portraits and hang them all up on his walls for his own selfish desires due to him enjoy watching his victims suffer. He also captured my family and friends too." Luigi told them with a disconsolate expression. "He also emits magical powers with a crystal in his crown which is extremely powerful to say the least, the way he shattered the dark moon back in the Evershade Valley and provoked all of the ghosts to go on a rampage proves his violent behaviour and power." He delineated.

The information that Luigi has presented to the mane five and Chase has sent chills down to all of their spines. This enemy Kimg of Luigis must be extremely powerful and aggressive, he also seems to have a wicked and powerful characteristic too. The thoughts of being trapped in a picture frame forever would be very daunting.

"Oh my, what an aggressive character." Chase said.

"Indeed, anything else?"

"Nothing Luigi, that should conclude the interrogation. Thank you so much." Hitch said with a smile.

"You're welcome."

"Now that that's out of the way, who wants cupcakes?" Izzy asked as she revealed a box of vanilla cupcakes.

The polterpup barked eager at the sight of the cupcake that he phased on top of the dinning table and chomped down on one of them. Making Izzy giggle and pet the ghost dog.
