On a bright and sunny day in the Mushroom Kingdom...

"Mario, where are you?" Yelled out Luigi, who was trying to look for his brother that had mysteriously disappeared. "Where could he be? I swear if he's in that Italian restaurant again..." He said to himself as he walked all over the place, but didn't see one trace of Mario anywhere. "Oh great! I can't find him. Wait a minute. If Mario's gone, then that means that I can become the main hero of the Mushroom Kingdom!" Said Luigi as he began to daydream about all of the fame, becoming the main character on multiple covers of his own games, and getting a kiss from Peach.

With these thoughts in his head, he got up and was about to look for Bowser so that he could go beat him up with help from the Toads, and take all of the credit, making him number one. As he was walking throughout the Mushroom Kingdom, he saw an M graffiti'd on a wall. At first, he thought it was just something someone did in order to honor Mario, but as he got closer, he saw that it was actually a portal of some sort. "This looks like one of those graffiti M's that Mario told me about when he went to Isle Delfino. I think he said to go through them, you had to spray some water on it, then jump in."

With that, Luigi took out his Poltergust and switched it to water as he sprayed the M. When he was done, he saw that it worked, as the M was now glowing, and seemed to be dragging him in. Luigi then jumped into the air as his body was reconstructed into a mass of molecules, and he was taken inside. It reminded him of those candies that were introduced a few years back in Mario Party 8.

Before he knew it, Luigi was high in the air, falling to what seemed like his inevitable doom. Luigi then screamed as his eyes bugged out and his mouth comically grew huge. Afterwards, Luigi started to pray in midair, hoping that he just might survive this.

As he was praying, he was suddenly caught by a cyan speeding blur with what appeared to be a rainbow trail behind it. He didn't care who this mysterious figure was, but it didn't stop him from clinging into her like a cat, not willing to let go.

When Rainbow landed she puffed her chest out and said "No need to thank me. I know that I'm the best flyer and hero of Equestria." Luigi however, didn't hear her, and still kept clinging onto her, cowering all the while. "Man, this guy's as much of coward as Fluttershy!" She thought as he still kept clinging to her.

"Uh, dude? You can let go, now." Rainbow said as Luigi looked like he had no intention of letting go. After a few minutes, Rainbow then tried prying Luigi off of her, but failed as Luigi was starting to stick to her like glue. Then she spun around, causing him to lose his grip and fall flat on his butt. "Huh? I'm alive?" Luigi curiously asked as he got up and dusted himself off. Then he saw that he wasn't harmed in any way.

"I'm alive! Oh thank you, thank you, thank you!" He cried out as he zipped towards her. "It's nothing. Just don't forget to thank your friendly neighborhood-" Said Rainbow as Luigi wrapped her in a tight hug, which was more of a death grip than it was a hug. "Thank you so, so much!" He said once again. "Actually, I think it would be better if you DID forget to thank me." She struggled to say.

Luigi then let go her as he started to back away and kept saying "Thank you, thank you, Thank you!" In the middle of him praising Dash for saving his life, he bumped into a shadowy figure with an oversized paintbrush, and at first, he assumed it to be Mario.

"Mario! I've been looking all over for you!" He said as he picked him up and started to hug him. As he was doing so, Mario came by and yelled out "You're not getting away so easily! Get back here!" Then he started to spray water at Shadow Mario, not noticing that Luigi was there.

Shadow Mario then got out of Luigi's hug and began to run all around Ponyville, giving Mario a wild goose chase to go on. "Nice going, green guy!" He yelled out at Luigi as he kept running after the shadow clone.

After a few minutes of chasing and fighting, Mario had defeated Shadow Mario, and he fell to the ground, turning into molecules as he did so. Mario then walked back to Rainbow to see her studying Luigi. "Wait a second! Green clothes? Skinnier than Mario? L on your cap? *gasp* You're Luigi!" She said aloud as Mario darted over to the two.

"Did you just say Luigi? The weaker, yet brave Mario Brother?" "The same!" Luigi said as he crossed his arms. Mario's jaw then dropped. "Luigi?! What are you doing here?" Luigi then began his explaination. "Well, I was in the Mushroom Kingdom looking around for you, until I saw an M graffiti'd on a wall. At that point, I remembered about that time when you went on vacation to Isle Delfino, and sprayed it with water. Then the M started to glow and pulled me in. Then I started to fall from the sky, going to become a Luigi pancake. That is until I was saved by this wonderful ray of sunshine." Then he tried to hug Rainbow again, but she pushed him away while saying "No more hugs."

Luigi reluctantly nodded and backed away. "Anyways, now that I've found you, we can go back to the Mushroom Kingdom. Everyone's been worried about you, you know." He said as he grabbed Mario's arm and began to drag him along in some random direction, but Mario stopped him. "Luigi, we can't go back."

Luigi then stopped pulling Mario and turned around. "What? What are you talking about?" Mario then sighed as Luigi let go of his arm. "What I mean is, we can't go home yet. There's no way out of here that I know of, and Princess Celestia is already trying her best to find a way out of here for me." He explained, leaving Luigi naturally confused.

"Princess...Celestia? Don't you mean Peach?" "Nope. I really meant Celestia." Luigi then gave his brother a strange look. "Mario, I think you've been here way too long. This place is already making you lose your sanity." "Not really. My sanity has been fully intact, from me saving a wedding, to fighting off Shadow Mario, to fighting my own friends and King Bob-omb to-" "Whoa whoa whoa, wait a minute. Did you just say that you saved a wedding?" Mario then nodded as he said "I'll tell you over pasta with my friends." Luigi nodded, and the two went off to go and introduce Luigi to the various ponies that Mario had met in his time in Equestria, and to eat some Italian food which they had no money for, so they had to do a dine and dash.

After running from an angry waiter who didn't get a tip...

"I still can't believe we did that." Luigi said as everyone nodded. "And I still can't believe that I'm actually stuck in a world with talking ponies." He thought to himself. "Well, it's all apart of the things that can happen in Equestria." Replied Mario as everyone turned a corner to see Shadow Mario standing there, obviously not happy. "Shadow Mario!" They yelled out.

"Really? This is second time today!" Mario said. "He is just ASKING to get his flank kicked!" Said Pinkie as she now suddenly had a shirt on and rolled up the sleeves while walking towards Shadow Mario to beat him up, but Twilight stopped her by putting a wall up and pushed her back. "Aw come on! Lemme at him!" Pinkie cried out as she tried to jump over the wall, but Twilight made it high enough so that she couldn't. "I don't know, Pinkie. He looks like he's planning something." She replied.

Fortunately, Twilight was right. Shadow Mario clapped twice, causing a green Wiggler to come charging at the heroes from far off in the distance. At first, Mario thought it was a certain blue hedgehog that he knew, but as it got closer, he knew that it was the Wiggler he fought back at Gelato Beach.

When Luigi saw the Wiggler, his jaw literally dropped to the ground as if he were a malfunctioning robot while his eyes were as big as yoga balls. Then he fell over to the ground, still stuck in that "horrified" expression. "My goodness! Is he okay?" Rarity asked worriedly as the girls checked up on him. Mario however, just kept a straight face, even after he saw Luigi fall over.

"Ah, he's fine. He'll snap out of it in about...2 minutes?" As he said that, the Wiggler then looked at Mario, and suddenly remembered about his defeat in Isle Delfino. The Wiggler then became angry as he tried to charge at our heroes, but they dodged the oncoming Wiggler, while grabbing Luigi in the process.

Afterwards, they had come together again to come up with a plan. "So, Mario. I'm assuming that you've fought this thing before. How do we take it on?" Asked Rainbow as she dropped Luigi. The rest of the girls also looked at him for his advice. "Okay, to take him out, we just need to roll him over on his back." "Sounds easy enough." Replied AJ. "Yeah, It's not. Wigglers are really heavy, so the only way to get them on their backs is to have a huge uprising of ground, and hope that they try to go up it, which they can't." As Mario was saying this, he realized that there was a Question Block in the side of a house, and that the Wiggler was coming towards them. Mario then decided to make a break for it with the little time that he didn't have, and try to hit the Question Block.

As he was running towards it, he noticed that the Wiggler was actaully aiming for him, and not the others. Mario then gulped at this, and saw how close he was to the Question Block. And right when the Wiggler was about to run him over, Mario dove at the Question Block and thought "Please be something good, please be something good!"

Then he hit the Question Block, causing a Mega Mushroom to come out. When he saw it, he got a smirk on his face as he grabbed the mushroom and abosrbed it, making him a giant.

When the Wiggler saw Mega Mario, he turned blue as tried to run away, but Mario just walked after him and stepped on him. Mario then lifted his foot to see if it was splat in the middle of the road, but was surprised when he didn't see it. At first, he thought it managed to get away, but then he saw red shoes sticking out from the bottom of his shoe, so he looked under it too see the Wiggler with a sad face on it smushed against Mario's shoe.

Then he knew what he was going to do next, so he turned around and told Fluttershy to close her eyes and cover her ears, but as he was doing so, he saw that she was already doing so, so he just looked at the viewer and shrugged his shoulders. Then he scraped the Wiggler onto the ground as it started to melt into graffiti.

When he was done, the Wiggler had seeped into the ground, releasing a shining object that Mario was familiar with. Mario then shrunk back to his normal size as he ran over to the shining object, which was next to Twilight. Mario then held out his arms as he ran towards her.

Twilight, thinking that Mario was going to give her a hug, just looked at him at first. While she was doing that, the scenery changed from being Ponyville, to a hillside, with flowers everywhere. There was no one else there, just her and Mario. She was about to give him a hug, but Mario ran past her and went towards the object, which turned out to be a Shine Sprite when he got closer.

Mario then did his little dance that he does when he gets a Shine Sprite while Pinkie joined him and did some random pose at the end along with Luigi, who snapped out of his "horrified" expression and joined them as the words "Shine Get!" appeared at the bottom of them. "...What was that?" Rainbow asked as everyone gave them strange looks. "Don't worry about it." Mario answered vaguely.

Twilight, who was now upset at Mario for apparently tricking her into thinking she was going to get a hug from him, galloped up to him and slapped him, immediately walking away to go to the library and drown her sorrows in ice cream. Mario then held his face as he looked at the others and asked "What just happened?" Everyone else shrugged their shoulders as they walked off with Luigi following Mario to the library to get something to eat.

Author's Notes

OK, a few things. 1. Sorry for not making any chapters in the past month, I think? I don't know to be honest. 2. The reason I added Luigi into this is because I thought that Mario might get lonely being stuck in a world with people you don't really know, and no one you know being there. So I added Luigi since he is the closest person to Mario. Also, it's the Year of Luigi, and I decided to do something special for the guy. I mean, come on. It's Luigi. He was going to show up in the story eventually. Anyways, back to what I was saying before. 3. The reason Luigi didn't get into the fight with the Wiggler is not because I have something against him. Oh no. Luigi is actually a pretty cool character when you think about it. The reason why is because, well, Luigi's a coward. No offense to any of you Luigi fans out there, but it's true. Nintendo has defined Luigi's character to be that of the cowardly type. Sure he'll get into a fight to help out the heroes, but most of the time, he'd probably be seen hiding somewhere with Fluttershy. 4. Obvious Mario Party and Sonic reference. Maybe he'll make a cameo in this story. MAYBE. I'm not entirely sure. 5. Yes, Mario broke the 4th wall. He'll be doing a lot of that, considering Mario games do in fact do it. Don't believe me? Go play Super Paper Mario and do NOT sit there and tell me that it doesn't break the 4th wall. Anyway, I think that's about it for now, And hopefully it won't take so long for me to make. Until then.
