Prologue: Let's-a-go, Mario!
It was been one week since the portal appeared and took Chameleo and his friends home, and that was before the portal turned into a mirror that only opens every 30 moons. It was a great day in ponyville, and another day of adventure for the Cutie Mark Crusaders, who seem to be having trouble getting their cutie marks.
"Ugh... No cutie marks. Again!" Inferno deadpanned.
"And we're covered in tree sap. Again!" Scootaloo deadpanned as well.
"C'mon, y'all. There's always next time." Apple Bloom assured.
"Yeah, besides, we'll still have lots of talents to try!" Apple Wasp agreed.
"I guess you're right." Sweetie Belle admitted, as she and the other CMCs were gonna head back, but heard Water Wing's voice. "HEY! GUYS! I FOUND SOMETHING!"
The CMCs went to Water Wing's location and saw what he found.
"What in Ponyville is that?" Apple Bloom asked.
"No clue, but it doesn't look like a well. Besides, I can't see the bottom of this thing." Water Wing answered as he came down from looking inside the strange well-like object.
"If ya ask me, this looks more like it's made o' steel instead." Apple Wasp pointed out as he tapped his hoof against it, getting a (CLANG!).
"I wonder where the bottom is." Scootaloo wondered out loud.
"I wanna know too, but what are we gonna do about this." Inferno asked.
"Oh! Maybe we could tell Twilight about it!" Sweetie Belle suggested, as the other members agreed and went to the Oak Library.
Later after the CMCs told Twilight about their discovery just outside of Ponyville, she gathered the rest of the Mane 6 along with Spike, Raptor, Soulfire and Makoto, and went to the steel object.
"Whoa. You foals weren't kidding when you said you saw... Whatever this is." Twilight said.
"Ya weren't sure about that, Twi? Even though I told y'all they were tellin' the truth?" AJ asked confused.
"Well, Applejack, some ponies can still have doubts about things, even when they know they are true." Rarity answered as Fluttershy took a peek at what was inside the object.
"It's so... deep." Fluttershy scarcely said as she when back to the others.
"Well, it does look like a well." Makoto responded.
"But this "well" is made out of steel. It's gotta be something else." Soulfire added.
"Hmm... Maybe it's a pipe!" Pinkie guessed with a (Squee!) and a smile, leaving the others confused.
"Pinkie Pie, you're so random!" RD said with a smile.
"You got that right, Dash." Raptor agreed, cracking a smile as well, when Spike noticed something strange.
"Uh, guys? Is it just me, or is that thing glowing for some reason?" Spike asked as he pointed to the well-like object, which seemed to be glow rainbow colors, catching the others' attention.
The glow became brighter as the well changed from green steel to rainbow crystals, followed by a bright flash of light. After the flash faded away, everything in world around the well and the creatures at its location lost all of its color and froze in movement completely. It was as if time had stopped, temporarily, as wind began to swirl around the well, picking up the Mane 6, CMCs, Spike, Raptor, Soulfire and Makoto one by one. They screamed in fear as each and every one of them went into the well, and the last one to go in was Pinkie Pie, who had no fear whatsoever as she whooped, "Whee-hee!"
They fell into Celestia knows how deep the crystal well for what felt like hours, and finally they saw a light below them, as it shined brighter and brighter, until the light covered their field of vision. When they could see again, they found themselves flying through the air after being shot out of that pipe. They got close to the ground and Twilight used her magic to stopped her flightless friends from crashing into the ground as Rainbow Dash and the others that could fly used their wings to land.
"Well, that was weird." Spike said.
"Hey! I'm back in my normal body!" Makoto said, catching the others attention. 
"Whoa! So that's what you really look like." Rainbow Dash commented.
"You look just like your counterpart at Canterlot High." Twilight noted.
"WAIT! You're saying Makoto and her counterpart have squirrel ears and a tail?!" Pinkie asked, caught completely off guard.
"Yep." Twilight simply answered.
"That. Is. AWESOME!!!" Raptor cheered, with the others agreeing.
"Those ears and that tail make you look really cute, Makoto." Fluttershy complimented the beastkin.
"Oh, stop! You're gonna make me blush!" Makoto bashfully said with her cheeks being a bit pink.
"But just so you know, everyone, Makoto's tail isn't a pillow or a cushion. She already gets enough of that from Noel." Soulfire told the others, much to the CMCs and Pinkie's dismay.
"Hey, y'all! I see a castle over there." Applejack called out.
"I wonder who lives there." Sweetie Belle wondered out loud.
"I think we're gonna find out, sis." Water Wing responded as everyone started going to the castle.
"Ooh! I wonder if we'll meet a princess!" Rarity squealed in excitement.
"Not surprised about that." Scootaloo said, being used to Rarity's excitement for meeting royalty.
"Me neither." Inferno agreed as he and everyone else were just about at the castle.
"Looks like we're here, y'all." Apple Wasp told the others as Twilight decided to knock on the door when it opened all of a sudden, revealing three humans and a strange creature.
There was a dead silence in the air as the wind whistled. Then the woman broke the silence.
"I wasn't aware of any visitors coming here." The woman said to the two men and creature.
"What should we do, dudes?" The creature asked the three humans.
"Maybe we should ask them who they are and introduce ourselves." The red-capped man suggested in a friendly tone.
"I-I don't know about this, big bro. But those creatures are a bit sca-sca-scary." The green-capped man said being afraid of the Garchomp and baby dragon.
"Well, maybe they're not bad." The woman responded as she walked towards the group. "Hello, my name is Princess Peach Toadstool, but you can call me Peach." She greeted with a bow.
"A-A-A-A-A princess?!" Rarity stammered as she fainted with a sigh, now knowing that she is in the presence of royalty.
"Umm... Is she okay?" Peach asked with concern.
"She's fine. Rarity's just being a drama queen." Rainbow Dash explained.
"Well, my name is Princess Twilight Sparkle, but please, call me Twilight. And these are all of my friends; Spike, Rainbow Dash, Makoto Nanaya, Soulfire, Raptor, Inferno, Scootaloo, Apple Bloom, Applejack, Apple Wasp, Pinkie Pie, Fluttershy, Water Wing, Sweetie Belle, and you've already met Rarity." Twilight said as she introduced herself and all of her friends.
"Well, good to meet you, paisanos. I'm Mario, and this my my younger brother Luigi." The red-capped man greeted as he introduced himself and his brother, who was taller than him for some reason. "And this little guy is Toad. We're Princess Peach's friends."
"But where are y'all headin'?" AJ asked them.
"Don't you know, dudes? We're heading out, to stop King Bowser Koopa!" Toad answered.
"King-who-now?" Raptor asked, showing his and everyone else's confusion.
"Could you explain who he is? Because we're not exactly from around here." Fluttershy requested.
"He's a big, mean, scary and rotton koopa." Luigi explained.
"C'mon Luigi! We beat him before, and we can do it again. We'll show him some real pasta power!" Mario said, trying to reassure his little brother.
"Wait dudes, you guys said you're not from around here. Where are ya from?" Toad asked the ponies and their friends.
"We're from Equestria! We somehow got here by going into a strange well. (Squee!)" Pinkie answered with a smile.
"Wait! That's means you're just like us! You guys must've gone through a secret warp pipe." Mario said.
"That's what that green steel well was?" Spike asked, as he and the others were surprised by the news.
"Yep, just like me and my big brother Mario, when we found and got sucked into a hidden warp pipe in Brooklyn while unclogging a tub drain." Luigi explained.
"Wait, y'all two are plumbers?" Apple Bloom asked the two men.
"That's right, little pony. Me and Mario are the best plumbers in Brooklyn." Luigi answered.
"Yep, and we're called the Super Mario Brothers!" Mario said.
"Well, if this "King Bowser Koopa," is a big threat here, we'll help you beat him!" Makoto said with her fist pumped into the air.
"Wait, you'll really help us?" Peach asked.
"Of course we will. Besides, I think we already know our way home." Soulfire answered, remembering the warp pipe they went through.
"Thank you." Peach said in gratitude.
"Don't worry, we like making friends and helping them." Twilight responded as all of her friends nodded, agreeing with that statement.
"Well then, paisanos... Let's-a-go!" Mario exclaimed as they all went off to find and defeat King Bowser Koopa.
