The city of Manehattan is a city home to many things: Fabolous fashion, splendid shops, delectable diners, and sensational songs from some of the best artists ever to hit the music scene.
But there's another aspect of Manehattan that attracts ponies (and non-ponies) from far and wide, from all walks of life. At night, the city is home to some of the greatest bars, clubs, and other entertainment spots that keep the partying going til the break of dawn.
Not all entertainment establishments opt to stand out with flashing neon signs and loud music. Some hide away, blending into the dark corners and nooks and crannies of Manehattan. These are more private and underground establishments, that cater to the interests of particular clients.
One of these private facilities, tucked away in a back alley far from most of the Manehattan night scene, is the Manehattan Flush Palace. If not for the sign that hangs from its door, you probably wouldn't know it was there even if you were staring at the door with your two eyes.
For you see, this "palace" is the most well kept secret of all secrets, at least in Manehattan. And that's because the patrons who flock to it are those interested in (or the unexpecting victims of) flushing. Toilet flushing to be exact. That's right, there are those who delight in nothing more than taking a ride inside a toilet bowl, swirling around with the waters, and being sucked down the drain and through the pipes.
And it just so happens that a certain pink pony works at this "palace". Pinkie Pie XIII, the lone clone who escaped being banished back to the mirror pool with her fellow clones after they had gotten out of control. For reasons unknown even to her, she had developed into her own version of the pony who created her. Ever since her lucky escape, she'd been living in Manehattan and doing odd jobs, until by chance she had stumbled upon this establishment. Now she works here, giving all ponies (and non ponies) who walk into the palace and willing to pay, an experience they'll never forget.
Pinkie Pie XIII inspected all of the stalls in the different rooms. Each gave off a nearly invisible glow, indicating the work of unicorn magic. After all, toilets in Equestria on their own were never capable of sucking down ponies. They needed assistance to do that.
How the toilets in this place worked was simple. Every night, the appropriate spell was cast on their seats, bowls, and the connecting pipes. Anyone unfortunate enough to trigger the flush cycle would get pulled in and sucked down. Fortunately, all the pipes were connected to a special sewer system that separated the waste from the patrons. The waste would be sent on to its appropriate destination, while the patrons would exit into a series of massive showers that would allow them to get all cleaned up. Then they would be free to either exit to the streets, or go back for another ride if they so wished.
Everything was as it should be, every toilet seat, bowl, and pipes had been checked and rechecked for the spell. And there was quite a variety for those to wished to partake in this very unusual interest. There were auto-flush toilets, old pull chain or handle toilets, squat toilets, and even ones designed like a foal's potty except the bowl was connected to the ground and had flowing water.
Just as Pinkie was exiting the final stall, she heard the door from above creak open, and the sound of hoofsteps could be heard from down the hall. The first customers of the night would soon be here!
Pinkie eagerly rushed to the front desk and dawned her employee's outfit, designed to look like a plumber's attire. She had white button overalls and a matching white hat with the palace logo (a pony spinning around in a toilet bowl) printed on it. All of which had been hoof made by the owner of the establishment, whom Pinkie had only met once.
Luckily, all that was needed to fool anypony (least word spread to Ponyville and the real Pinkie learn one of her clones was still at large) was a fake mustache. With it on, Pinkie Pie XIII was ready to greet the customers and help them on their way.
The first patrons of the night soon revealed themselves. Vinyl Scratch (better known by her stage name of DJ-PON-3) and her roommate (and close friend) Octavia Melody, the famous cello player. Vinyl seemed positively ecstatic, even having taken off her shades and allowing her violet eyes to be seen! But Octavia seemed more hesitant, even ashamed of being here.
"Ah come on, Octy," Vinyl encouraged. "You know you wanna do this. That's why I brought you here."
Octavia just blushed and looked at the ground. "This is uncouth. I still can't believe you're forcing me into this. I feel so ashamed to know that ponies actually pay for this, to be flushed down the toilet like their own rubbish."
Vinyl only laughed. "Hey, nopony judges. They all come here to take a ride in the porcelain pool, and that's just what we're here for," Then she said to Pinkie. "We'll take one pull chain model for two."
"That'll be ten bits each, if you please," Pinkie instructed in a gruff voice. Vinyl hoofed over the money but a second later before Octavia could utter a syllable of protest. "Excellent! Right this way, please. Your chair awaits."
"Come on, Octy! This is gonna be a blast!" Vinyl encouraged, leading her friend along as they trotted down to the toilets.
Pinkie stopped in front of the second door from the left, marked solely for the type of toilet it carried. The palace didn't distinguish between stallions and mares (or colts and fillies). She pushed it open, revealing a massive row of open stalls, all of them featuring toilets with the old fashioned pull chain to activate the flush cycle. "Go ahead, take whatever one suits your fancy. Just be sure you're both on the seat when you pull the chain," She instructed. "May I ask what brought this on? We here at Manehattan Flush Palace don't judge."
Octavia blushed bright red, as Vinyl laughed and explained. "You are never gonna believe this! As a foal, Octy here tried to learn how to potty train before she was even a year old! But she slipped, fell, and pulled the handle, causing her to get sucked down the drain! I caught her once, trying to do the same at our apartment!"
"Vinyl!" Octavia protested.
"Ah, a young, curious flush lover. We've got plenty of those here," Pinkie declared as she stepped back. "Well, enjoy your ride you two."
"Thanks," Vinyl replied with a smile. "Okay, Octavia. You climb on the seat first, then I'll join you. No use backing out now, we payed for it."
Octavia reluctantly obeyed and said nothing. Vinyl soon climbed up onto the seat with her, grabbing the pull chain with her magic. "Flush for two!" She declared, forcing the chain down!
With a loud "Fwoosh!" a stream of water shot up from the toilet, blasting both ponies high into the air! Then they came back down and were pulled into the bowl, spinning around until they disappeared down the drain with a satisfied "Glug, glug, glug." to indicate a flush well done.
But those two music lovers were just the first of many many flush lovers to come trotting up to the desk that evening, all of them eager to varying extents for the flushing experience of a lifetime.
To Pinkie Pie XIII, each patron's case was unique. They each had different types of toilets they wanted to try, and some even wanted to try them all. But there were some that were truly unique, some that she couldn't forget.
Pacifica Glow (who ran a special nightclub of her own) enjoyed multiple trips down the training potties. As it turned out, she had infamously gotten out of potty training by flushing herself down the toilet as a foal, and then pretending to be scared of the toilet. Only once she'd grown too big to fit down the pipes, had she been forced to give up her diapers.
Octavia slowly came to embrace her flush lover attitude, opting to get revenge on Vinyl by flushing her down the same pull chain toilet they had shared. Then "accidentally" flushing herself.
A stressed out fashion designer by the name of Coco Pommel hoped to flush away her troubles, figuring it was better than the usual nightclub scenes and wouldn't carry the risk of damaging her reputation (the palace had been very careful to avoid the snooping eyes of the paparazzi). She actually ended up going for the auto-flush toilet, as it was "simple, straight, and no hassle".
But by far the best experience Pinke witnessed that night, was when the crowds parted and they saw a pony by the name of Moondancer, dragging along Prince Blueblood, who was kicking and screaming in protest. "Release me this instant, you cur! I am royalty, and I will not be treated like common trash!"
Moondancer just snorted. "You're no prince charming! You deceived me into believing you were a true gentle stallion, when in reality you're just a smelly old turd who doesn't know his place. Well, there's only one thing to do with a turd like you," She tossed an entire sack of bits onto the counter. "What's the best model you've got for royal pains like this?"
"Ooh, opting for a bit of humiliation are we?" Pinkie grinned, flexing her fake mustache. "Lucky for you, there is one toilet that suits your needs. Make way, everypony, the chair awaits!"
Some customers who had been the palace multiple times, gasped! They knew what the chair was!
The eager crowds followed Pinkie, as Moondancer strained herself considerably to tug Prince Blueblood along. Thankfully, all those books on advanced magical study had payed off.
At last, at the bottom of a huge flight of stairs, rested a door that had "Warning!: Emergency Use Only" printed in large letters. Pinkie just swiped a card through a slot resting next to the door, and it slowly rose with an ominous "Beep, Beep".
Prince Blueblood looked up, and gasped! There stood a huge, white toilet! But it looked quite dusty, and the pipes all rusty. The surrounding area was covered in cobwebs and looked like it had gone months, maybe even years without seeing a broom.
"Dump him in the bowl, just be careful not to fall in yourself," Pinkie cautioned to her patron. "If you do, you're only leaving one way."
"Thank you for the warning. Now come on you overgrown turd!" Moondancer declared, lugging Prince Blueblood into the room and towards the toilet. "It's time to give a royal pain like you a royal flush!"
Blueblood was alarmed! He started kicking and screaming loudly! "No! Please! I'll be good, I swear! I'll pay for dinner! I'll compliment you every day! Anything!"
Moondancer just shook her head. "All I wanted was somepony to treat me right, that would've cost you nothing. But now it will cost you everything," With a great deal of effort, she managed to flick her horn and hurl the stallion face first into the massive toilet bowl!
Blueblood landed with a splash! All around him he could hear ponies laughing! "Stop that! This isn't funny!" He complained! "When I get out of here, I'm going to lodge a complaint at Manehattan City Hall! I'll have this place shut down!"
But Pinkie Pie XIII only laughed. "Oh, I wouldn't bet on that. You see, unlike the other toilets in this facility, this one is a one way trip. You'll go straight on through to the sewers. And it's enchanted so that anypony who goes down the drain, forgets everything that happened to them up to a certain point. You won't even remember this place, let alone how to find us," Then she turned to Moondancer and asked. "How much do you wanna make him forget? For legal reasons, we can only do up to twenty four hours."
"That's more than enough time for him to forget about our horrible date." Moondancer declared.
Pinkie grinned and stood near the handle, ready to push it down. But then she got an idea. "Why don't you do the honors, Moondancer? Let off some steam and get whatever you want off your chest."
Moondancer smiled, carefully trotting over to the handle. Then she looked down at Blueblood, desperately trying to climb out of the bowl only to find the sides too slippery. All he accomplished was splashing the water about and getting it onto his mane and tail. "Blueblood, I really thought we had something special when we met and you agreed to take me on a date to Manehattan tonight," Moondancer declared. "But now I see, you were just using me like you've used so many other mares. You're no prince, not in my book. A true prince would respect his fair maiden and treat her with the respect and care she deserves. You're not even worthy of being considered royalty, because the truth is, you're nothing more than an ugly, stinky, overgrown turd. And you know what happens to turds!" She forced the handle down with all her might!
"Noooooooooooooo!" Blueblood screamed in vain, as the toilet roared to laugh! Everypony who had gathered round laughed, watching in delight as the snobbish prince spun around and around in the massive toilet bowl, and was then sucked face first down the drain. His massive rump being the last thing anypony saw, before they heard a faint "Glug, glug, glug", and the toilet refilled with no sign of the prince anywhere.
Moondancer sighed in relief, blowing a raspberry down towards the bowl. "Goodbye and good riddance to that overgrown turd!" She hissed.
Pinkie Pie XIII just smiled. It was just another successful night for her here at the Manehattan Flush Palace.
