I don't own My Little Pony, Sonic X, or Phineas and Ferb. I do own Knuckles' and Amy's glove designs.


The sewers beneath Station Square would have been a dreary sort of peaceful, were it not for the cartoonish bouncing noise that echoed throughout the subterranean labyrinth every 3.14 seconds. The source of the noise was currently traveling north through one of the tunnels with three other creatures.

The entity in question was a small equine with sky blue eyes, three balloons on it's flank, bright pink fur, and a slightly darker pink mane, which also happened to be insanely curly. As in, balanced precariously between Afro and "Mad Scientist." (Hey! I don't make fun of your hair!) Sorry Pinkie- wait, what?

... Anyway, the other pony in the small group was a quiet shade of orange, sporting a straight blonde mane, emerald eyes, white "freckles," and a triple apple mark. She wore a plain brown cowboy hat and a pair of simple red hair hair ties at the end of her mane and tail.

The impromptu team's third member of the group was a pink hedgehog who looked decidedly less cheerful than her like-colored peer. She had jade green eyes, a downswept, bob-cut-like qull-do, a red dress with white trim, strawberry boots with a white stripe down the middle, a red headband, and dark red fingerless gloves with light grey trim and gold rings for cuffs.

The last member, and only boy, of the quartet was a red mole-like creature with violet eyes, deadlock-like quills, and a white crescent mark proudly displayed on this chest. He wore scuffed red and yellow shoes with green armor-like sock cuffs and a silvery Lego brick shaped buckle, brown-but-used-to-be-white bandage thingies on his large three-digit hands (pointedly going around the large red spikes that adorned his namesakes), and an angry scowl directed at both everything and nothing (both of which were attempting to avoid his gaze, to no avail- PINKIE!- hehe, sorry).

The "mole" opened his mouth, as though he were about to impart some profound wisdom upon his companions.

"This whole thing is Sonic's fault!"

(Welp, so much for that. Back to the peanut gallery.)

The hedgehog would have none of that. " All Sonic did was try and stop Eggman. He didn't mean for us to get us sent here."

The cowpony nodded in agreement, "'Sides, he didn't have anythin' ta do with Pinkie Pie an' me showin up here. maybe them emeralds o' your's acted up on their own, lahk the Elements o' Harmony did."

"Yeah!" Pinkie Pie, who was still bouncing, said, "Maybe the Chaos Emeralds and the Elements sensed that there was some kind of ancient prophecy or something that said a great evil was coming to this dimension that could only be stopped by the combined strength of heroes from two other dimensions! Or maybe it's some sort of crossover fanfiction based on an anime based on a video game franchise that a tall nerdy teenager is making in his spare time, sometimes when he should really be catching up on his homework! Applejack and Amy are absolutely right, no one is to blame for this mess except whoever decided the anime would involve interdimensional travel."

Amy, the pink hedgehog, stared blankly at the still-bouncing party planner, "Uh, thanks Pinkie, I think."

Unfortunately, Knuckles had quickly recovered from Pinkie's torture of the Fourth Wall. "Regardless, Sonic shouldn't have pushed it so far!"

"At least he's not afraid to fight back!"

"Sonic just likes getting into fights for kicks!" The last Echidna almost cringed the moment he said it. He knew better than anyone how much of a lie that was, but this girl was seriously pushing his buttons.

Applejack looked back and forth between her strange new friends before trying to break the tension, "It's gettin late everypony. We should set up camp here fer now."

Thankfully, it mostly worked. "Yeah," Knuckles muttered, "I'll go…find something for firewood."

With that, the Guardian aimlessly trudged off, leaving a thoroughly steamed Amy Rose behind him.

The young farmer sighed. If only Twahlaht were here. She'd know what ta do.


Meanwhile, on a deserted island…

Dr. Heinz Doofenshmirtz had had a rough 26 hours, 7 minutes. First, an Inator that he swore he couldn't remember building had hummed to life in the middle of his very evil dancercize program and ripped a (thankfully stable) hole into the very fabric of reality. Then a huge rainbow-colored energy beam shot out of the crystal tree on the other side of the portal and into the suburbs. And then, when he "changed the channel," a weird blue robot fell through the portal, followed by a huge wave of white light that enveloped the entire penthouse.

When Dr. D next woke up, it was not to the out-of-place (but not unwelcome) scent of fresh chocolate cake that greeted him. Nor the sound of a window, door or wall breaking to signal that his nemesis had been called into work early again (or that the Doctor had slept in… again). It wasn't even to his not-so-estranged daughter chatting with her friend Candace about their respective annoying inventor relatives, which would mean he had really slept in.

No, what L.O.V.E.M.U.F.F.I.N.'s co-leader awoke to was the smell of the sea, the calling of gulls, the lapping of waves, and a hard metal floor.

The evil scientist surveyed his base of operations. There was thankfully no damage on the macroscopic level to anything but the lab's retractable roof, which had been destroyed during his most recent battle with Perry the Platypus (that was a fun one. So many pies). The power was out, meaning that the Penthouse had been separated from the rest of the building (he kept the off-grid auxiliary power supply on the floor below his). Finally, there was scurrying in the vents, meaning that NORM's squirrel had gotten loose.

The lack of commotion outside told him that he was either on an uncharted island or a land of cappless mushroom creatures who were used to things like weird aliens and structures spontaneously appearing on the beach.

A second look around told Heinz that he had not, in fact, come to Cappie Town. The "Art Style," while similar, had some major differences to that of his favorite penguin king's home. And yet it was also vastly different from his own world.

Having thoroughly analyzed his situation, the would-be villain saw only one viable course of action: explore outside.


Doofenshmirtz was amazed at the sight before him.

Not the island. That, while decidedly beautiful, was rather underwhelming, as he could have seen from one side of the little isle to the other were it not for the small cliffs.

Or the giant futuristic tower he was currently staring at.

It was about as tall as his building pack home, not counting the cliffside it had fused with. Although considering the way the bottom was broken, he was probably only seeing the control tower, not whatever used to be the base proper. It vaguely resembled the Space Needle in Seattle, but was considerably stockier (if a building could be considered stocky).

The evil scientist had no doubt that it was inhabited and armed to the teeth. Thus, he removed his lab coat (having changed out of his exercise gear before leaving his penthouse) and used a long piece of driftwood to fashion together a white flag of Peace and approached the larger dwelling.

The door-to an elevator he realized- was open when he arrived. Abandoning his driftwood and donning his lab coat, the inventor entered.


"So, this is what the inhabitants of this miserable world look like? Conquering you will be easier than I thought."

Heinz eyed the man who had spoken to (or rather of) him, and was less than impressed. He was,to put it bluntly, a bald, fat guy with ridiculously thin limbs and a huge, messy orange-brown moustache under a pointy nose who vaguely resembled an egg. This "Eggman" wore a black jumpsuit under a red tuxedo-like jacket with white and yellow trim, both of which had several buckles and straps. He also wore white gloves, work goggles on his forehead, and small tinted glasses that hid his eyes.

In fact Doff felt alarmingly normal compared to him despite his beaky nose, slouched back, ever-present labcoat, and four-digited hands (which he had a feeling weren't common in this world).

"I wouldn't be so quick to judge." The scientist explained, "For one thing, I am not of this dimension, or world if you prefer. For another, my power comes not from my body, but my mind."

The portly man grinned at his gangly guest, "A state I know all too well, my friend. Ah, but we have forgotten to introduce ourselves. I am Doctor Ivo Julius Robotnik, otherwise known as Dr. Eggman."

His counterpart held back a snicker, "And I am Doctor Heinz Doofenshmirtz, future ruler of the ENTIRE TRI-STATE AREA! You know, start small and all that jazz."

To this, the newly dubbed Eggman laughed heartily. "So true my friend. I take it you aren't very interested in this world, then?"

"Not in the slightest." The Druselsteinian immigrant replied, before adding, "But from your tone I would say you are."

Mobius's Bane allowed himself an impressed smirk, "I see nothing gets past you, good Doctor."

"Oh, you'd be surprised. Say, why don't I help you take this place over?"

Eggman's interest was piqued, "A team-up, you say?"

"Yeah! I mean, other than trying to get home I'm not really doing anything for a while and what better way to pass the time than causing wanton destruction and general chaos. Besides, everybody needs backup sometimes."

Eggman was grinning widely now, "I like the way you think Heinz. This could be the start of a beautiful, horrible friendship. Come, let me show you around."

And with that, the Earth had gained its greatest threat since 1945. There were few who knew what tomorrow would bring. (Well what did you expect, a happy ending?) PINKAMINA DIANE PIE, GET BACK ON YOUR SIDE OF THE WALL! (Hehe. Oopsy.)


Will our sewer-bound heros find their friends? What are Doof and Eggman plotting? How are the others settling in at Thorndyke mansion? And where is Rainbow Dash? Find out next time on-

Pinkie, we are not doing this.

But-

No.

*sigh* All right.

*quietly* Read and review, everypony!
