Twilight Sparkle, Moondancer, and Lemon Hearts walked to the doors of the canterlot castle. They stopped as two Bat Ponies landed in front of them, causing them to take a few steps back. Both Bat-Ponies crept to them, hissing lowly.

"Who are you?" the one on the right asked "And what do you want?" Lemon Hearts swallowed hard and approached them.

"Uh... my name is Lemon Hearts," she spoke "and we're here to help Nightmare Moon in any way we can."

"...She's one of the Castle's workers," the one on the left spoke "but what about the other two?" Both approached Twilight and Moon Dancer.

"And what are you two here for?" the right asked "Here to plead to release Celestia from her sun?"

"And perhaps have Nightmare Moon 'reform'?"

"...For some Thestrals," Moondancer commented "they sure are protective over her."

"...Did she say what I think I heard?"

"Yeah... she called us Thestrals!!!" The right squeed, hopping like a foal. "Finally! Somepony who calls us by our species name, not by our looks!"

"...I don't get it." Twilight commented

"Long story short," the left answered "Luna casted a last minute spell that caused some ponies to be her own kind; us, Thestrals."

"But everypony calls us 'Batponies'!" The right added, quoting with his hooves "Seriously! Why don't they call you unicorns 'horn-ponies' or the pegasi 'bird-ponies'."

"Very prejudiced if you ask me!"

"What is your name, the one with the sweater?" Moondancer cleared her throat.

"My name's Moondancer," and I'm just here to check out some books."

"Then follow us!"

"We know the way!"

"And you stay with your friend, grape unicorn."

"It's Twilight Sparkle!" Twilight growled. The Thestrals laughed as they opened the door and entered the castle, leading Moondancer to the royal library, whistling a tune together.

"I... guess we can enter." Lemon Hearts spoke "Come on, I'm certain we won't encounter anymore Bat Po-" Some Thestrals turned to them with an angered look. "Uh... I mean, Thestrals, as long as we stick together!" The two walked into the castle, though felt really awkward as the Thestrals kept a close eye on them, especially the fact that their eyes glowed a pale yellow in complete darkness.

Outside, Twinkleshine, Lyra Hearstrings, and Minuette peaked from a bush behind.

"Are you sure about this?" Twinkleshine asked "It looks like they have this under control."

"I'm certain about it!" Minuette replied "Lyra, is your lyre ready?"

"It just needs a few tweaks," Lyra answered "but it should be ready."

"Do we really have to do this?" Twinkleshine whined "They look fine! I think we should go back and-" Before she could continue, Minuette put on a face mask.

"Have you been flossing?" she asked in a Germane accent.

"We're heading inside!!!" Twinkleshine ran inside, screaming like a school foal. The Thestrals stood back and watched in curiosity as Twinkleshine ran in, completely confused on what just happened. But then they heard very calming music approaching to them. The music made them drop their weapons and they slowly began to drift into sleep. Outside, Lyra played her lyre whole her horn glowed, making the music head to the guards as Minuette had on earmuffs. As soon as the music stopped playing, all of the thestrals were fast asleep, leaving the two to enter quietly. Minuette tapped Lyra on her shoulder.

"Yeah?" she asked

"Did you floss?" Minuette asked. Lyra's eyes widened as her pupils shrunk. She took a few steps back, but ran as fast as her hooves could carry her! "Come back!!! I zink I see that you have a cavity! Schnell!!!"

"I flossed!!! I really did!!!"

Lemon Hearts and Twilight Sparkle entered the darker throne room as some Thestrals worked together to carry the last cage filled with Celestia's canterlot soldiers. Sitting on Celestia's throne was Nightmare Moon herself as she held a small, animal looking rock with white eyes & a smiling face in her hooves.

"What do you mean it's a one time use for us!?" Nightmare Moon yelled at the rock "How am I suppose to defend my subjects from other things worst than Celestia!?"

"Easy as this," Skippy 'replied', though it was just Nightmare Moon acting as Skippy. "you are one of the biggest losers I've been stuck with for the last one thousand years, hearing you complain about how you are stuck on the moon and you're talking to a rock right now!"

"Skippy! Why can't you be nice!?"

"If I was nice, then where would you be, fatty!? Oh! That's right! You'd still be on the moon, wailing for yourself instead of exiting earlier!"

"Why do I even take you with me!? You're such a jerk!"

"... I'm gonna commit suicide." The rock 'jumped' out of Nightmare Moon's hooves and fell the floor, all of which could be heard in slow motion.

"NO, SKIPPY, NO!!!"

"~weee~"

"NOOOOO, SKIP, NOO!!!"

"~eee~"

"NOOOOOOOOOOOOOOOOOOOOOOOO, SKIPPY, NO, SKIPPY NO!!!!"

"~eee!"

"NOOOOOO!!!" Skippy feel to both Twilight and Lemon Heart's hooves with a low thump. "SKIPPPY!!! SAY SOMETHING!!!"

"Your friends dead."

"Buck you Skippy." Both Twilight and Lemon stared at the scene, to each other, then back.

"...That was... something." Twilight commented. Lemon Heart's horn glowed and she gave back Nightmare Moon the rock.

"Here's... Skippy, Nightmare Moon." Lemon Hearts spoke sheepishly. Nightmare Moon looked at Skippy for a few seconds, but stopped and sniffed the air.

"That smell." She commented to herself

"Smell?" Nightmare Moon stood up and began to sniff around them, followed by sniffing their manes.

"...Cake." She gave them the evil eye "There's only three types of ponies that I know share the sweet smell of banana cream cake: Soldiers, students, and servants!!! You don't look like soldiers, but what are you two!?" Both unicorns froze with fear and trembled as they saw Nightmare Moon standing above them, realizing that she's just as tall as Celestia and, perhaps, even more powerful. Loud screaming was heard as well as the trotting of some hooves. Turning around, Twinkleshine entered, followed by Lyra Heartstings.

"RUN!!!" Twinkleshine yelled "COLGATE IS HERE!!!"

"I FLOSSED ALREADY!!!" Lyra added "I DID!!!" They tackled Twilight and Lemon Hearts, knocking them against the wall on either side. Entering the room was Minuette in a full dentist outfit.

"Who here hazen't taken care of zere teeth!?" She asked in her Germane accent. Twinkleshine, Lyra, and Lemon Hearts pointed at Nightmare Moon.

"Minuette?" Twilight asked "What are you-HMMPH!?" Twinkleshine Covered Twilight's mouth with her hoof.

"Who is this pony!?" Nightmare Moon asked "And why is she speaking like that?"

"Ah! Ze name is Dr. Colgate," Minuette replied "Equestria's mozt finest Dentist. Ja!" She ran to Nightmare Moon and knocked her into Celestia's throne, opening her mouth forcefully and looked inside "Ooh! You've got quite ze chompers zhere! Zhey're like zat of piranha! How long has it been since you brushed?" Nightmare Moon tried answering, though her mouth was still wide open

"Ha heh hihizoed hor ha housah hearah."

"A zouzand years!? Zis is unacceptable!!! Don't move; zis will only hurt for a moment." She conjured up a bag that opened up, revealing many dentistry equipment and power tools. Nightmare Moon saw this and tried to escape, but she was easily strapped down by some conjured up straps. "And vhere do you think you're going? Consider zis a lesson in taking care of your teeth. Ja! Ze rest of you can help me with this."

"...What is going on!?" Twilight asked "I told you three to stay put!"

"We wanted to," Twinkleshine replied "but Minuette really wanted to help you out."

"And why is she talking in a Germane accent?"

"It's her alter ego, Colgate," Lyra replied "she's been hiding it away from us after her braces were removed. It happens whenever she sees really bad teeth and when she stays up at night time."

"...She had braces?"

"Vhy are you just sitting zhere!?" Minutette yelled "Help me or else you'll get an immediate appointment!"

"We better do what she says!" Lemon Hearts yelled, standing and rushing to Colgate's side. Everyone else followed and rushed towards Colgate's side. "Very good. Now: Lyra Heartstrings, make sure our patient here doesn't try to escape again. Twinkleshine, you're in charge of cleaning my equipment. Lemon Hearts, spread ze word about our patient! Twilight Sparkle, hand me ze laughing gas!"

"Laughing gas?" Twilight asked

"Ja! Laughing Gas! It's ze container labeled!" Twilight turned to see the laughing gas as Lemon Hearts ran out of the throne room. She picked up the laughing gas, but the top came off, letting a stream of gas come out.

"Uh oh!"
