My Little Pony Equestria Girls: Monster Mash-Up Musical

Outside Castle Revolta at nearly night, Sullivan leads his henchmen into a large jet plane. The 4 henchmen Rarity hypnotized to be monkeys were free from trance, but covered in a couple scrapes and bruises, the leader’s club now has bite marks on it, since they mistaked it for a banana. The 2 henchmen that Fluttershy and Phantasma scared are still pale, shivering, and clutching themselves with fear. The 2 henchmen Applejack and Elsa electrocuted still have straight hair and are covered in soot. The 2 henchmen Sunset and Lagoona sent over the waterfall in the underground lake are soaking wet. The 3 henchmen from the food court are still covered in frosting from the explosion of Pinkie Pie’s cupcakes. The 4 henchmen from Revolta’s lair - the one Twilight levitated into the cell, the one Sibella dropped still covered in green gunk, the one Spike pulled the pant leg off, and the one with the sleeve Matches burned with his fire breath. The 3 henchmen Rainbow Dash distracted as a bat were now free from the ice blocks Enid froze them in, but were cold and wrapped in towels. The 2 henchmen Trixie and Minimal bound with the pipe were free, but had small crates stuck on their feet. The 3 henchmen Starlight and Galactica stuck to the wall of the gift shop with Serious String still had a bit of the pink sticky goo on them.

"Look, I know you all had some trouble with those Rainbooms before," he said, "but I’ll give you another chance. Besides, with this," he said, pulling out his crystal ball, "I’ll know exactly where they are." He smirked, leading his battered henchmen into the jet plane. "Those girls are gonna pay for making Martha break up with me." They all go into the jet and the cargo bay door closes behind them. The fake officer from the castle door, who now feels better after being scared by Tahlia, is at the cockpit controls, acting as the pilot. In the cabin, the henchmen buckle in their seatbelts. Sullivan sits in the cockpit with the fake officer. The plane takes off from behind Castle Revolta. In the cockpit, Sullivan gazes into his crystal ball, which shows the Rainbooms’ tour bus. "I’ll get you, my pretties," Sullivan declared darkly. "And your little dog too."

Our view zooms into the crystal ball, and with that, we transition to the Rainbooms’ tour bus at night, driving on a city freeway. Inside the bus, Sibella is telling the Rainbooms about the day she, Winnie, Elsa, Phantasma, and Tanis first won a volleyball game against the Calloway Cadets.

"And while we were playing," Sibella explained, "we found out mid-game that the Calloway Cadets had put a remote-controlled device in the volleyball. That way, they could control how the ball moved."

Rarity gasps in disbelief. "A remote-controlled volleyball?"

Rainbow Dash is outraged. "That’s cheating!"

Sibella chuckled. "Right? But, get this - while we were playing, our coach’s talking dog accidentally swallowed the remote while eating a hot dog."

The group burst into laughter.

"That made the controller go A.W.O.L.," added Matches, grinning.

Enid chimed in, "And the device in the ball only activated when the dog had the hiccups."

Sibella nodded, amused. "His hiccups caused the ball to go haywire."

Twilight was intrigued. "So, in short, he sabotaged their cheating."

"Exactly!" Sibella agreed. "And thanks to him, we managed to win the volleyball game against the Cadets."

"We won by 1 point!" Phantasma chuckled.

"No way!" Pinkie Pie exclaimed.
"Awesome!" Rainbow Dash added.
"Amazing!" Rarity echoed.

Tanis leaned back, a sweet smile on her face. "And Miss Grimwood let me keep the trophy for my mummy case." Rarity gazes with a big grin and sparkly eyes at Tanis.

Sibella laughs. "We’ll never forget what the Cadets said after they lost." She imitates Tug. "'We had the tactics.'"
Phantasma imitates Jamal. "'We had the strategy.'"
Winnie imitates Miguel. "'We had the equipment.'"
Elsa imitates Grunt. "'But we still lost.'"
Tanis imitates Baxter. "'Affirmative.'"

They all laugh at the story. Suddenly, a sputtering sound is heard. They all look concerned. They look out the windows. They’re slowing down.

"Uh, Sunset? Why are we slowing down?" Phantasma asked, confused.

Sunset gazes at the dashboard, nervously. "Bad news, girls. We’re out of gas!"

Sunset pulls the bus off the freeway and lurches it to a complete stop on the side of the road. The bus’ doors open and the Rainbooms and the Grimwood Girls come out. A confused Minimal comes out of her caravan trailer. "Girls," she called out, "I didn’t know what was going on inside my trailer. What happened?"

"We ran out of gas," Applejack explained apologetically.

Minimal’s eyes widened in concern. "Oh. Oh no."

Rainbow Dash opens up a secret compartment behind the bus and takes out a gas can. She shakes it close to her ear, but all she heard was a faint slosh of the liquid inside. She looks disappointed. “Only a few drops left,” she said glumly.

The others look upset.

Sibella glanced around, trying to stay optimistic. "Maybe there’s a gas station around here somewhere."

Sibella turns into a bat and flies to the top of the bus and looks around the quaint neighborhood, her green eyes narrowing. With a curious look, Twilight takes her wand from the pocket of her black dress and straightens her hat. Then an idea flew into her head. She looks up at Sibella, who scans the neighborhood, shadowing her eyes with her wings.

"Sibella?" Twilight called, catching the vampire’s attention. "Is there a... magic way to get gas?" She waved her wand playfully in the air.

Sibella's eyes lit up with excitement. "Ooh, I love your thinking, Twilight!" she said as she flies inside the bus. Her purple transformation light pulsated briefly inside. Back in vampire form, she comes out holding her spell book, her demon tail swaying excitedly. "Growth spell! We grow the can, and the gas inside will grow with it!" She shows the Growth Spell page to Twilight. The magic words say "Magnora Gantuan".

Twilight chuckled briefly at the idea. "Perfect," she said, nodding in approval.

"I know! I like it too!" Sibella grinned.

"So, what’s the rhyming rule for this spell?" Twilight asked.

Sibella recites it. "'To make things grow, focus your mind, and with your attention, you'll surely find.' So, to magnify the object, you have to magnify your attention upon it." Rainbow Dash gives Sibella the gas can. She sets it on the ground. "While you cast that spell, you can’t let anything distract you."

Twilight walks up the can and points her wand at it. "Alright. Here we go. Focus," she murmured to herself. She senses Matches cringing and frowns. Her purple eyes shift back to him. "Something wrong?" she asks, clearly unamused.

"Sorry, it’s just... your stance is, uh..." Matches moves quickly all over Twilight, posing her awkwardly, all over her personal space. "Chin up, elbows out, feet apart, back slightly arched." He steps back. "How does that feel?"

"Great," she said through gritted teeth, trying her best to stay patience.

"Oh!" Matches grinned, still fiddling. "One more thing."

Twilight, Spike, Sunset, Sibella, and Enid all groaned in unison. "Matches!" they all exclaimed.

"Right, right. Sorry," Matches muttered, his ears drooping. He quickly backed away.

Matches tries to adjust Twilight’s elbow one more time. Twilight shoots him a look. Matches throws up his claw-like-hands and steps back. Twilight focuses hard and recites the growth spell. "Magnora Gantuan!" The tip of the wand throws off bright purple flashing sparks. Twilight winces, but does her best to stay focused. The can begins to grow.

"Don’t let the magic scare you," Matches called out from the side.

Twilight nodded without taking her eyes off the can. "Okay," she replied, concentrating even harder.

"Elbows!" Matches shouted, startling her.

"What?!" Twilight snapped.

"Elbows up!" Matches called out.

Twilight lifts her elbows as high as possible. "No, no, no, too high! That’s too high!" he shouted.

“Matches! She’s trying to focus!” Sibella called out, clearly exasperated.

"Oh, yeah, yeah, yeah!" Matches replied, only half listening. "Focus on the can!" He continued to murmur under his breath, sounding absent-minded and even more annoying with each word. "Focuuuuuus... Focuuuuuuuuuussssss…"

"MATCHES!" Twilight finally snapped, completely losing her patience. "AH, FORGET IT!" Failing, Twilight lowers her wand his frustration. The glow on the wand fades. Everyone looks at the can. It’s still its ordinary size. They all look confused and disappointed.

Suddenly, a high-pitched squeaky voice is heard. "It worked!" Everyone looks down. They were shocked to see this: Sunset is TINY! She runs up to the can, excited. "The can is HUGE!" She looks over at the tour bus. "And the bus is huge!" She turns her excited gaze the Rainbooms and the Grimwood Girls. "And you’re all--" She looks down at her mouse-sized body, realizing what really happened. "Oh, no," she muttered.

Twilight’s eyes widened in disbelief. "Sunset?!" she called out, lowering her hand to the ground so Sunset could step onto it. She gently lifted her up. "Sunset? What's going on?! What happened?!"

Sunset looked up, still in shock. "Uh, Twilight. I think you made me shrink. I’m so small!"

Twilight’s mouth hung open. "What?! But--" She turned to Enid, hoping for an explanation. "Enid, how did this happen?!"

Enid frowns apologetically. "Well, Twilight, if you mess up a spell, there are consequences."

Sibella patted Twilight on the shoulder sympathetically. "Look, Twilight. It’s not your fault. You only messed up because someone wouldn’t stop bothering you."

Everyone glares at Matches, who looks regretful. "Sorry."

Sibella sighs in exasperation.

Sunset piped up, "How about we just go find gas the proper way this time?"

Overlapping:
Spike nodded. "Yep. Good idea."
Enid added, "I couldn’t have said it better myself."
Twilight smiled, "My thoughts exactly."
Sibella agreed. 'You took the words right out of my mouth."

They all look over to the other Rainbooms and the Grimwood Girls, who agree with this. Twilight gently sets Sunset on her shoulder while Sibella gets the gas can, and they all head into the neighborhood together. On the freeway ramp they just went down, Henry rides his motorcycle down and to behind the bus and hides his bike behind one of the freeway bridge’s support beams. He parks his motorcycle, takes off his helmet, and takes off after the girls, still unnoticed.

In the neighborhood, the Rainbooms and the Grimwood Girls walk down the lit sidewalk, observing the houses. Sibella clutches the gas can. Sunset sits on Twilight’s shoulder.

Twilight glances at her, concerned. "You alright, Sunset?"

Sunset chuckles with embarrassment, "Well, I kinda feel like a pirate parrot".

Sibella offered a sympathetic smile. "Don’t worry, Sunset. You’ll be back to your own size before you know it."

They continue on. As they search around the delicate neighborhood, Twilight looks over at Sibella. She sees her holding a submarine sandwich instead of the gas can. Twilight rubs her eyes, then finds the gas can back in Sibella’s gloved hands. Sibella notices her staring at it.

"Uh, Twilight? Are you okay?" Sibella asked.

"Yeah, I’m alright," Twilight asks. "I thought I saw you holding a sandwich." She shrugs. "Ah, well."

Sibella looks at the gas can, confused. But she shrugs it off too. Twilight looks over to Rarity. Instead of the gold Egyptian style necklace decorated with pretty and colorful gems Rarity was wearing as part of her transformed mummy look, she now sees a necklace made of bacon in its place. Twilight shakes her head, and she sees Rarity wearing the golden Egyptian necklace again. Rarity notices her. "Twilight? What’s wrong, darling?"

Twilight chuckles nervously. "Sorry, Rarity. I thought I saw you wearing a necklace made of bacon."

"Bacon?" Rarity looked down at her necklace, incredulous.

Twilight sets Sunset on Sibella’s shoulder, then turns her gaze over to Winnie and Starlight. In Twilight’s vision, the light blue bow on the neck of Winnie’s blue dress is now a blow made of pizza slices. Starlight has cookies and a lidded cup of milk in her spacesuit’s belt. "And Winnie, your bow is now made pizza." Winnie is bewildered. "And Starlight, in your belt, I see big chocolate-chunk marshmallow cookies and a lid on a cup of milk." Twilight blinks, she was hallucinating. The Rainbooms and the Grimwood Girls are very confused indeed. "Sorry. I’m starving."

They all see what’s going on now. "Oh."

Minimal reaches into her pocket. "Here’s some food."

"I don’t think you’re gonna want that," Enid muttered uncertainly as Minimal hands Twilight 3 gumball-shaped pieces of red food.

"I am so hungry, I could eat a whole elephant," Twilight stated.

Fluttershy gasped, her eyes wide. "What?!"

"Figure of speech, Fluttershy," Twilight said reassuringly.

"Oh." Fluttershy sighed in relief.

Twilight puts the food Minimal gave her in her mouth and she crunches them. Her eyes go wide as she chews. Then, as she winces, steam bursts out of her ears, making a train whistle sound. Twilight spits out flames! "What is that?!" she croaked, hoarsely.

"Fire Balls," Minimal said nonchalantly, as if it was totally normal.

Lagoona holds up a piece of stale sushi. "Here, have some real food: fresh sushi," she said chipperly. Twilight looks at the sushi in disgust. "It’ll knock it right out," Lagoona added.

"That’s not fresh," Twilight said, scrunching her nose in disgust. "I’m not even sure that’s sushi anymore!"

Lagoona's offended. "It’s just 3 weeks old," she said defensively.

"I’ll cook it for you," Galactica said. She retracts her helmet and aims her eye lasers at the sushi. Twilight watches. Galactica’s heat vision turns off, revealing the sushi now black and burnt. Twilight gasps. Lagoona is shocked.

"Whoops," Galactica gasped, slightly embarrassed.

Sibella gave Twilight a reassuring pat on the shoulder. "Don’t worry, Twilight. We’ll get something to eat at the gas station. When we find one, that is."

Twilight nods in thanks. Sitting on Sibella’s shoulder, Sunset gazes over to see colorful lights coming from a nearby house. "Uh, girls? Look at that house." They look over at the house. "Maybe the one who lives there knows where the nearest gas station is," Sunset stated.

Sibella smiles. "Great idea, Sunset." She turns to the rest of the group "Come on, girls." They all head over to the house. A few moments later, they arrive at the front stoop of the house. Twilight looks over at Trixie. "Alright, Trixie. Ring the doorbell."

"One bell ring coming up," Trixie said as she rings the bell and waits. Suddenly, a burst of light shoots through a crystal that is hung on the door, shocking them all. Trixie races back to the others.

Overlapping:
"Goodness!" Rarity exclaimed.
"AHH!" Pinkie Pie screamed.
"Yikes!" Rainbow Dash shouted.

A bright, colorful image of an old man’s head is projected out.

"Greetings cosmic children of the universe," the holographic wizard head announced. The Rainbooms and the Grimwood Girls watch. They don’t know what’s going on. "And welcome to my serenity circle! Please leave any bad vibes outside the healing vortex. And now prepare…" With a "FZZZZT" and a "BLOOP", the image disappears.

The door opens and a white haired bearded man comes out. He groans in frustration. "I knew I should have gotten that warranty!" He hits the crystal with his fist and is promptly zapped in the head. "AHH! Ow."

Enid’s eyes widened. "Mr. Mysterio?"

"You know this guy?" Starlight asked, looking surprised.

Sibella's face lit up with excitement. "You bat we do! He used to be our magic teacher!"

Sibella and Enid race up to Mr. Mysterio, who’s examining his crystal. "Mr. Mysterio!" they both called in unison. Mr. Mysterio embraces both girls.

"Enid. Sibella. Good to see you," he said warmly. He glances at the other Grimwood Girls. "Oh, and the rest of your friends and..." he sees the Rainbooms "Holy Tooth of Zadar! Are those the Rainbooms?"

Applejack grins. "Ya darn tootin’ we are!"

Mr. Mysterio laughed heartily. "Well, the pleasure’s all mine, girls." He turned back to Sibella and Enid, clearly thrilled to see them. "So, my former students, what brings you here to my humble home?"

Sibella explained the situation. "We’re all on a quest to find the Zodiac Stone, Mr. Mysterio. But the Rainbooms’ tour bus ran out of gas, and now we’re getting hungry."

"Well, you’re all in luck," Mr. Mysterio replied with a grin. "I happen to have a gas pump in my backyard, and I just ordered some pizza, made some sandwiches, and I just finished making some cakes."

Pinkie Pie’s eyes sparkled. "Ooh! Are you having a house party?"

"You got it!" Mr. Mysterio said, leading the group inside. The house was cozy but full of character. Color-changing lights shone on a crystal ball in the center of the room, and scented candles with different-colored flames flickered in the air, giving the place a mystical feel. "I can’t believe it!" Mr. Mysterio said, amazed. "My favorite students teaming up with the Rainbooms to find the Zodiac Stone? Grim would have been very excited to hear that."

"Who’s Grim?" Rainbow Dash asked. After a moment, she suddenly got it. "Oh. Miss Grimwood. Right."

Mr. Mysterio turns to Twilight. "So, anyway, Miss Sparkle, forgive me for asking this, but where is Sunset Shimmer?"

"Down here," The still tiny Sunset called out. She's sitting on Twilight’s shoulder, waving up at Mr. Mysterio.

Mr. Mysterio’s eyes went wide. "Goodness gracious! She’s tiny?" Sunset nodded nervously, offering a small smile. "But how?" he asked.

"Well, Mr. Mysterio," Tanis started. "Twilight was trying to do a growth spell on the gas can, but..." she scowls at Matches. someone kept bothering her while she was casting it."

Spike intervenes. "Tanis, don’t make him feel worse." Tanis smiles apologetically at Spike and Matches.

Mr. Mysterio chuckled, clearly understanding. "Oh, the spell backfired, huh?" Twilight and Sunset nod. "Well, don’t worry. I can fix that. I got a potion in here that can grow shrunken things back to their normal size." Mr. Mysterio takes out a dropper and heads for the kitchen. Twilight and Sunset smile at one another. "But where did I put it?" He rummages through potions in the pantry and finds a potion bottle with blue liquid labeled “Shrink Reversal”. "Ah-ha! Here it is." He takes the bottle out and shows it and the dropper to the girls. "You just need one drop of this for the effects to work." He dips the dropper into the bottle, collecting some of the liquid before heading back to Twilight. He drops a droplet of potion on Sunset, who’s in Twilight’s hands. Glowing pink energy surrounds Sunset and a bright light briefly flares. It quickly fades, revealing Sunset, now back to her normal size. Twilight struggles to hold her. They both fall.

"Oof!" Twilight and Sunset grunted as they toppled to the ground. They both get up. The human-turned-swamp-creature examines herself and smiles, glad to be back to her ordinary size. "Well, that fixes that problem," Sunset beamed, her voice also back to normal.

Everyone laughed, relieved that the spell had worked.

"Well, the snacks are out back where the party is," Mr. Mysterio said, leading the group toward the back of the house. "Come on."

(They all follow Mr. Mysterio. Rarity suddenly hears her phone ringing. Rainbow Dash, Applejack, Fluttershy, Pinkie Pie, and Sunset hear their phones too. Rarity, Pinkie Pie, and Sunset take their phones out of their hair. Applejack, Rainbow Dash, and Fluttershy take their phones from their pockets. Rarity saw that she had a call from Sweetie Belle. Applejack was getting a call from Apple Bloom, Rainbow Dash from Scootaloo, Sunset from Principal Celestia, Rainbow Dash from Vice Principal Luna, and Fluttershy from Principal Cadance. Twilight, Spike, Starlight, Trixie, and the Grimwood Girls notice. The Rainbooms all hang up. The Grimwood Girls look confused.

"Uh, who was calling?" Sibella asked, puzzled.

Twilight glances around nervously. "Uh, well, Sibella, you see, uh--"

Twilight whispers into Sibella’s ear. The vampire suddenly gets it. Her green eyes go wide. "Oh. A Halloween surprise, huh? Interesting."

They all continue to follow Mr. Mysterio. Outside the mall at Canterlot, Sweetie Belle scowls with a phone to her ear. Apple Bloom and Scootaloo wait expectantly.

"Ugh! I can’t get through to them!" Sweetie Belle exclaimed. "Rarity usually answers her phone instantly!"

Nearby, Celestia, with her own phone to her ear, sighs and shakes her head. Luna and Cadance are standing by her, equally perplexed. "We’re not having any luck, either," Celestia admitted, lowering her phone.

Luna frowns. "I don’t understand. What are they doing with the Grimwood Girls?"

Apple Bloom tilts her head thoughtfully. "And how did they get turned into real monsters?"

Scootaloo crosses her arms, narrowing her eyes in thought. "Well, what were they doing last time we saw them?"

Cadance raises a finger, recalling, "Well, we told them about that early Halloween party at the Canterlot Planetarium. We even mentioned it was one of the best places in town for a Hallowe..." She trailed off, realization dawning on her. "Oh."

At the Canterlot Planetarium, Celestia, Luna, Cadance, and the Cutie Mark Crusaders head in. As they look around, concerned. "Alright, everyone," Celestia said like a leader, "Have a look around and for some sort of monster transformation machi--" They all spot Flash and Vinyl going down a hallway at a far end. They all share quizzical glances, then head off after them. In the hallway, they spot Flash and Vinyl enter Sarah’s lab and get suspicious. As Flash, Vinyl, Derpy, Sarah, and the Dazzlings work on the serum, The principals and the Crusaders come in.

"Flash, DJ, what are you..." Celestia started to ask, her voice trailing off when she saw the others. She couldn’t help but stare. "... doing?"

Vinyl froze. "Principal Celestia?"

"Uh, what’s going on?" Luna asked.

Scootaloo sees the Dazzlings and gasps. "And what are they doing here?!"

Flash quickly raised his hands. "Wait, wait, wait! They’re on our side this time!"

Celestia blinked in surprise. "What?"

Sarah stepped up as well. "They’re trying to help us with a serum. It’s all for an important reason." She shakes Celestia's hand. "Hi, I’m Sarah Scientist. Fluttershy and I were in elementary school together."

"Okay..." Celestia replied politely, then turned her confused gaze to Flash, Vinyl, and Derpy. "But that doesn’t answer why we saw you 3 on the news last night with Rainbooms."

"Transformed into monsters?" Luna added.

Vinyl raises her hands innocently. "That’s not our fault!" she said quickly. Apple Bloom looks concerned, Scootaloo raises an eyebrow, and Sweetie Belle pouts. Vinyl relents. "Okay, okay. Confession time. Sunset said she wanted to take a break from Halloween costumes this year, and she and her friends decided to become real monsters this time. They wanted it to be a Halloween surprise. They said they were going to be stuck like that for 3 days."

"It was the work of my transformation chamber, "Sarah added, pointing back to it. Celestia, Luna, and Cadance glance at one another, then Apple Bloom, Scootaloo, and Sweetie Belle do too.

Flash added, "And they went on a quest to find the Zodiac Stone, a magical stone with elemental powers. DJ gave them a book about it. They must have let the Grimwood Girls join them. And we need to finish this serum for them before they unleash the curse."

Overlapping:
"The what?" Principal Cadance asked, her brow furrowing.
"Beg your pardon?" both Celestia and Luna asked in unison, equally confused.
"Excuse me?" the Crusaders chimed in, utterly lost.

"The curse!" Derpy piped up. "The curse that protects the Zodiac Stone by turning into a ghost dragon or something."

Vinyl nods. "That’s why the Dazzlings are here. They cursed Canterlot High by singing, so we thought they might know how this curse works."

Celestia gazes over at the Dazzlings. Adagio looks nervous. Aria looks embarrassed. Sonata waves sheepishly. The principals and Crusaders think for a moment, then gazes at the Flash, Vinyl, Derpy, and Sarah. "Would you like some extra help?" Celestia asked, worried, but concerned. Flash and Vinyl smile at each other. Derpy smiles. Sarah beams.

Vinyl removes her shades. "It would be an honor."

"Oh, and thanks for helping with information about the stone in your book, DJ," Luna added.

Vinyl gave a modest wave of her hand. "Anytime. Oh, and by the way, my real name is Vinyl Scratch."

They all look appreciative. "Alright, let's get back to work," Sarah said calmly. Celestia turns to her.

"Oh, and Sarah?" she asked. "Thanks for helping the girls out."

"Of course," she added before her appreciative smile turns into a worried frown. "Come on, Celestia. We better hurry. If we don’t finish that serum..." She pauses as Celestia gazes at her. "The girls are doomed," she finished. Celestia gazes downward, worried, then she gets to work with the others.
