Disclaimer: The Mario Bros and characters related to them and mentioned belong to the people at Nintendo. And the three characters from Sonic the Hedgehog belong to the makers in SEGA.

Now Clayton Mario, the OC belongs to NUTCASE1733. Trust me, he did a very good job with the info on the Mario characters and such. XDDD.

Anyways, what I do own is my main OC Miguel going to be mentioned here. The story itself is a collab story between both me and NUTCASE while we were role playing. I hope that you all enjoy the story. So on with the show!

Mansion Madness

It was another bright day in Grass Land within the Mushroom Kingdom. Just right at the outskirts of the capital; Toad Town, a portal shaped like a golden ring appeared right as two young boys around fifteen along with three humanoid animal creatures came through. They all took the time to get a good look at their surroundings right as one of them, a cocky blue hedgehog, looked around and smiled as he took a long breath.

"Well, here we are guys! The Mushroom Kingdom!" Sonic said with a wide, happy grin. He then took another deep breath. "Ahhh! Fresh air and wide open spaces! Just the way I like it!"

"Got that right, Sonic!" The red figure with dreadlocks said to Sonic while looking around their new surroundings. "I'm glad Shadow agreed to look after the Master Emerald for me. I really needed the break..."

"What do you think of all this, Sam?" asked a young, two tailed fox who was looking at a young man who wore a pair of old glasses, who was also looking around his surroundings.

"Have you guys got any idea how long I dreamed of a chance like this? I may as well have died right now and gone to heaven."

A young man with a strange gold and silver sword with a four pointed red star only chuckled as he used its blade to mystically close the portal as he spoke, "Ha ha ha. And if not for the fact that I've found you doing weird things like a cartoon thanks to that emerald fragment you've found, then you wouldn't be here right now, Sammy."

"I should have known something was up when I found that thing," Sam said as he looks to his glasses for a moment and puts them back on after checking on them. "There's never been emeralds mined out of Texas. Onyx, Topaz, and Opals yes, but never emeralds."

"Anyway, since you're the big expert on Mario's world, can you tell where we are right now?" Tails asked while looking to the human boy.

"Yeah, easily this is Grass Land. The greenery alone is a dead giveaway."

"Got that right, Sammy!" Sonic said as he stretched his legs and body. "AHH! And nothing like the good open spaces for us to run around in! Wouldn't you agree, Knuckles?"

Knuckles could only nod at the blue hedgehog's words, "Man, and to think that I was too hard headed to know that Miguel wasn't lying about having the Master Emerald."

"Hey, you were a Knucklehead at the time, Knux. It happens."

The red echidna could only growl at Sonic's words right as Sam looked around before he spoke up pointing to a random green hill, "Ok, judging by our current location we shouldn't be far from Toad Town. That hill behind us looks a lot like the one in Paper Mario which leads from Goomba Village, so the west gate should be ahead of us."

Miguel could only chuckle as he spoke while putting his huge sword away through mystical means as it vanished from sight, "Right, Sam. It shouldn't be too much of a worry seeing that I'm a bit known to the place as well as Sonic and the guys. Though...It's been two years since then."

"Relax, it's a straight walk from here from what I saw in the game," Sam said while thinking. "Reality issues aside, there shouldn't be anything different, really."

"Yeah it's like when I got the chance to see some of the Sonic games back at Miguel's place," Tails said while thinking and looking around at the same time. "The scale is smaller than it is in reality but a lot of what is seen is pretty much the same."

"Yeah, but it's good to have some fans who see us as heroes, little bud," Sonic said with a nod while at turning to the dirt path. "Anyways, we should get going guys! Man, is Mario really going be surprised to see us again! I wonder how he's doing anyways."

"If I remember correctly, he's likely stuffing his face or something." Knuckles said as he began to shudder at a thought. "At least he's saner than Lina."

"That's for sure, Knux." Miguel added with a shrug before turning to the dirt path. "Anyways, let's get to town guys alright?"

Sam nodded with that statement, "Yeah I'm feeling a bit hungry anyway. Might as well have lunch at Mario's."

The group walked down the stretch of Goomba Road until moments later they all reached the west gate Sam had mentioned. They soon entered Toad Town while noticing how busy the citizens are with their daily routines. Sam could only smile at the sights he was seeing.

"Just as I remember from the game. That on our immediate left is Russ T's house. He's the town's brainiac and runs the local library. There's a shop, they got a lot of good stuff at discount prices from what I remember. Around the corner is the local martial arts dojo."

Knuckles could only look at the young man as he spoke, "Man, you really are a hot shot in this stuff, aren't you, Sammy?"

Sonic looked around the town and whistled with awe at the sights, "Whoa, got to hand it to the people here. They've got good tastes."

"I'll say, Blue," Miguel said while he noticed a few posters of the famous Mario Bros. A third individual dressed in light blue clothes compared to Mario's red and Luigi's green was seen in the picture; he also looked about the same age as Miguel and Sam. "Seems like things are doing fine here to me."

The third individual in question was Clayton Mario, Mario and Luigi's youngest brother. The news of a third brother greatly surprised Miguel when they first met back when the evil RoboRobotnik began his conquest, but the two became very good friends.

Clay is about the same age as Miguel, but he's already had his fair share of adventurous exploits from helping his brothers rescue Princess Peach during their trip to Dinosaur Land, helping stop the evil Smithy, and a few other crazy quests.

Clay is described as being laid-back but can be very short-tempered at times, especially when enemies get on his nerves. He's got a quick wit and a sharp tongue which often leaves his enemies crying if they don't end up throwing temper tantrums first. Miguel chuckled, figuring that Clay was like an alternate version of Sonic almost.

"Heh heh heh!" Tails chuckled while looking around as he spoke, "I wonder what the Marios been up to lately?"

"Well, as far as I can tell not a whole lot." Sam said while at the same time looking around Toad Town. "Things have been slow for the last few years as far as new adventures go when it comes to the games. They've been doing a number of sport and party-themed games to keep the money flowing enough to make a bigger adventure. I suppose the same applies with real life."

"You might be right about that, Sam," Tails said while looking at a newspaper headline from a stand and started to read. "Says here that the Mario brothers had barely won a regional soccer tournament over some guys called the Wario brothers."

This caused Miguel to whistle at the words as he said, "Wh-Whoa! Now that's something, Tails."

"Heh. Got that right, kid," Sonic added as he continued to walk along. "Wish I could try out for a game of soccer sometime. Sounds like fun!"

"We just might later on." Tails said while looking around. "Hmmm. Now if memory serves, Mario's house has a shortcut here in town."

"This is it here, tails." Sam said as everyone saw him standing next to a huge green pipe. "This was how one got to Mario and Luigi's place in Paper Mario. So here we go!"

With those words, the four eyed young man jumped into the pipe and down he went. Needless to say this caused everyone present to look on a bit surprised at his bold actions. Knuckles was the first to speak while looking dumbstruck.

"I'm still not used to that, guys!"

"Heh heh heh. But it sounds like fun to me, Knux. So lighten up! Here I go!" Sonic said while at jumping into the green pipe to go after Sam.

"Yeah, Knux! Let's get going!" Miguel said while dragging the red echidna with him to the pipe.

"Here I come!" Tails exclaimed happily as he followed the others into the pipe that leads to the Marios' home.

Little did they all know that this is just the start of another adventure coming.

A/N: Sorry it took long to put up everyone but honestly I was a bit distracted with doing some things with my friends as well as having Clay to make a few add ons with these two chapters. Well, this is the first crossover story I did with characters from the Mario and Sonic series. So enjoy the next chapter.
