My Little Pony Equestria Girls: Monster Mash-Up Musical

The Rainbooms’ tour bus rides along a scenic road lined with trees. Inside, the Rainbooms and the Grimwood Girls sit in their respective bus seats. Sunset’s driving. In the front row seat, left side: Rarity, Tanis, and Lagoona. In the front row seat, right side: Galactia, Winnie, and Pinkie Pie. In the middle row seat, left side: Starlight, Sibella, and Twilight. In the middle row seat, right side: Phantasma and Fluttershy. In the back row seat, left side: Trixie, Rainbow Dash, and Enid. In the back row seat, right side: Elsa and Applejack. Spike is sitting in Starlight’s lap, while Matches is with Enid. Minimal is in the caravan trailer hooked up at the back of the bus.

"So, you were each teaching the Rainbooms how to use their monster powers?" Matches asked. Spike chimed in, "Like Sibella’s helping Twilight with her witch magic?"

"AWESOME!" Spike and Matches exclaimed in unison, clearly excited.

Rarity perked up, her excitement bubbling over. "I know, right? Let us go over what they taught us," she said. A series of flashbacks shows each of the Rainbooms outsmarting Sullivan’s henchmen with their monster powers.

First, a flashback of Rarity and Tanis in the treasure room. Rarity narrated, "In the treasure room, Tanis told me about her hypnotism skills, and I hypnotized Sullivan’s henchmen, telling them they are monkeys." Tanis added, "She even said the leader’s club was a banana." The Rainbooms and the Grimwood Girls are heard laughing.

A flashback of Fluttershy and Phantasma in the attic. Fluttershy narrated, "In the attic, Phantasma showed me how to possess and control people, objects, wind, and temperature." Phantasma added, "We scared them out of their wits with a prank." Rainbow Dash is heard gasping in awe, clearly proud of Fluttershy. "Told you Rainbow Dash would be proud," Phantasma said off-screen.

A flashback of Applejack and Elsa in the lab. Applejack narrated, "In the lab, Elsa taught me that Frankensteins were electric." Elsa added, "And we used our neck bolts and some jumper cables to get those henchmen quite the shock." The girls are heard laughing at this.

A flashback of Sunset and Lagoona at the underground lake. Sunset narrated, "Lagoona and I got to go underwater and use lake weeds to bound up those thugs." Lagoona added, "They even went over a waterfall."

A flashback of Pinkie Pie and Winnie in the food court. Pinkie Pie narrated, "In the food court, Winnie taught me that happy thoughts can put away my claws." Winnie added, "That way we could knock those muscular minions out cold. And they got covered with frosting from Pinkie Pie’s exploding cupcakes." The girls are heard laughing at this.

A flashback of Twilight, Sibella, Spike, and Matches in Revolta’s lair. Twilight narrated, "And I used the levitation spell to lock up a henchman in Revolta’s lair." Sibella added, "While I gave them a fly and fall into gooey green gelation." "Don’t forget a bite!" Spike added. "And a burn!" Matches chipped in.

A flashback of Rainbow Dash and Enid in the gym. Rainbow Dash narrated, "And I got to turn into a bat while Enid and I were in the gym." Enid added, "While I worked my freeze ray magic."

A flashback of Trixie and Minimal in the storage room. Trixie narrated, "And I got to camouflage myself like a chameleon and then me and Minimal tied the men up with a metal pipe in the storage room." Minimal added, "Which was hidden in the library behind the fireplace which was lit with cold fire - the same cold fire Trixie uses with her magic. I guess magicians do reveal their secrets - to their closest friends." The girls are heard laughing at this.

Finally, a flashback of Starlight and Galactica in the gift shop. Starlight narrated, "And Galactica and I were sticking a few of those guys to the walls in the gift shop." Galactica added, "Using Serious String."

Back in the present, the tour bus continues traveling through the scenic road. The Rainbooms and Grimwood Girls are heard laughing inside. Behind the wheel, Sunset ponders for a moment, then gets an idea. She pulls over to the side of the road. The others look confused.

"Uh... Sunset? What are you doing?" Twilight asked.

"Why did you stop?" Sibella asked.

Sunset puts the bus in park, gets up, and approaches Enid. "Enid, you said Sullivan’s crystal ball used to be a normal prop, right?"

Enid gets up from her seat. "Yeah. So?"

Sunset paused for a moment before continuing. "So I was wondering, maybe..." She points to her geode, which is still in the form of a ring, like the other Rainbooms'.

Enid suddenly getting it "Oh. Sure, be my guest."

Enid offers Sunset her arm. Sunset touches her wrist, her geode activates, and her eyes glow with white light as we zoom into them. In a flashback, Enid watches through Sullivan’s office door just a crack as the corrupted human sets a clear crystal orb on a stand at his desk. Sullivan goes to the window, gazing out coldly. Enid’s eyes narrow quizzically. Suddenly, a wisp of Equestrian magic zips by her, startling her. It flies into the office and touches the clear crystal orb, making it magical and glow green. Hearing this, Sullivan turns back to his desk and sees the crystal ball. He comes over to it with a trance-like expression. He picks it up and gazes at it, amazed. He presses his fingers against it, and it shows him various views of different parts of the castle. Sullivan smiles excitedly. Shocked and worried, Enid backs away from his office door, then runs away from it down the hallway. Back in the present, Sunset’s eyes return to normal and she quickly lets go of Enid’s wrist, letting out a big gasp.

"What is it, Sunset?" Sibella asked, worried.

"Are you alright?" Enid asked, also concerned.

"I know how Sullivan’s crystal ball got its powers!" Sunset exclaimed, her eyes wide. "It was magic, but it wasn’t monster magic, it was Equestrian magic - our kind of magic!"

Pinkie Pie was shocked. "Another wisp of Equestria magic?!"

Sunset nodded grimly, her face tense with fear. "It looks like Equestrian magic didn’t just go around Canterlot. It must have gone to Monsterdom too!" She said.

Sibella’s eyes widened in realization. "Wait! Are you saying--?" Sunset nods, fearfully.

"Great. So once again we’re in danger because of Equestrian magic!" Rainbow Dash said in frustration.

"Oh boy." Fluttershy whimpered.

Twilight gets up and gently puts her hand on Sunset’s scaly green shoulder. The human-turned-swamp-creature gazes at the Princess of Friendship.

"It’s gonna be alright, Sunset." Twilight said softly. "We’ll find the Zodiac Stone before Sullivan can lay even one hand on us."

Sibella agreed. "Sullivan’s probably miles away from us by now. We just have to make the most of what's in front of us."

Sunset’s anxious gaze turns into a look of determination. She knew they were right. There was no use dwelling on what had already happened. What mattered now was moving forward, together.

"Then let’s get going," Sunset said bravely. "We have a stone to find." They all get back into their seats. Sunset gets back behind the wheel. The bus drives back onto the road and they continue on.

Cut to the Mall in Canterlot City at dusk. At the food court, Celestia, Luna, Cadance sit at one table while Apple Bloom, Scootaloo, and Sweetie Belle sit at another. They all look exhausted from their search.

"Oh, for sweet apples sake," Apple Bloom groaned. "We’ve already searched for the Girls all over Canterlot! Downtown, uptown, in the park, at the school!"

Sweetie Belle, equally exasperated, let out a sigh. "It’s like they’re not even in town anymore."

"I just hope they’re not planning anything sneaky," Luna added cautiously.

Celestia was concerned, but remained hopeful. "Don’t give your hopes up just yet," she said gently. "We’ll find them. We still have 2 more days until Halloween, so just need to keep looking.

Suddenly, the sharp voice of the anchorman on the TV caught their attention, breaking the lull in the air. "Last night," the anchorman’s voice boomed from the television mounted on the wall by the service counter, "we had an unexpected early Halloween hit from the Rainbooms." They all turn towards the TV.

The group turned toward the TV in surprise. "What?" she muttered, clearly puzzled by the mention of the Rainbooms.

On the screen, the anchorman and anchorwoman were sitting side by side at the news desk. "You heard me. The Rainbooms are looking really monstrous this Halloween."

Celestia stood from her seat, her brow furrowing in confusion. "Excuse us? Can you turn that up, please?" she asked the food vendor nearby, gesturing toward the TV.

"Sure," the vendor replied with a smile and pressed the button to increase the volume, making it easier for them to hear.

The anchorman’s voice rang out more clearly. "In fact, their costumes look so real they don’t even look like costumes at all."

Then the anchorwoman spoke. "Here is a video recorded from a pedestrian’s phone featuring the Rainbooms in their new Halloween looks."

The video shows the Rainbooms singing “Scary Scary” last night while going around Canterlot in the new monster forms after being transformed. They were surprised to see Twilight as a witch, Sunset as a swamp creature, Pinkie Pie as a werewolf, Rainbow Dash as a vampire, Rarity as a mummy, Applejack as a Frankenstein, Fluttershy as a ghost, Starlight as an alien, and Trixie as a dinosaur.

"Rainbow Dash?" Scootaloo whispered.

"Applejack?" Apple Bloom asked.

"Rarity?" Sweetie Belle murmured.

Cadance squinted at the screen, her brows furrowing. "Are those the Girls?" she asked incredulously.

Then the anchorwoman added, "We even have footage of the Rainbooms talking to 3 high schoolers at the park after their song."

Celestia's eyes narrow slightly. "Wait, that kinda looks like..." The screen shows the Rainbooms talking to Flash, Vinyl, and Derpy in the park. "Flash? DJ?" she exclaimed in disbelief.

"Derpy?' Luna added, bewildered.

The 3 principals and the Cutie Mark Crusaders all glance at the TV with wide-eyed shock. They all glance at their respective groups. They could not believe what they just saw!

Cut to the Canterlot Planetarium at the same time. Inside, a TV on a wall in Sarah’s lab shows the news too. Sarah, Flash, Vinyl, Derpy, and the Dazzlings watch, worried. "And here is footage from the amusement park in Monsterdom - Ghouls Funland, where the Rainbooms perform a song for the Grimwood Girls," the anchorwoman announced. Another video shows the Rainbooms performing with their instruments on a stage for the Grimwood Girls in the restaurant at Ghouls Funland.

"Twisting Turntables!" Vinyl exclaimed, clearly shocked by the news. "Twilight and the Rainbooms are with the Grimwood Girls?" She couldn't believe it!

Derpy let out a sigh of relief, smiling softly. "Oh, I’m so glad they’re okay!"

"Well, we still need to make that serum before they unleash the curse," Sarah said, her expression hardening as she turned back to work. "We better get back to work."

Adagio scowls and scoffs. "Uh, they’re the ones who rendered me and my sisters powerless in a music concert," she said with a bitter sneer. "Who cares if they’re okay?"

"We care!" Flash said firmly.

"And you three should care too," Vinyl added with a pointed gaze.

"Well, I guess I kinda care a little bit," Sonata said, almost as if trying to lighten the mood.

Aria nudges her sister. "Sonata!" she whispered.

"What?" Sonata asked innocently.

Flash and Vinyl exchanged a look of annoyance. This wasn’t the time for the Dazzlings to be arguing among themselves.

"Sarah," Flash said, turning to the scientist, "if you don’t mind, we’d like to have a word with these three ex-sirens."

"Oh. Sure," Sarah nodded.

Vinyl glances over at Derpy. "Derpy, help Sarah while we’re out," she instructed. Derpy nods and gets back to work with Sarah.

Flash and Derpy step out of the lab in annoyance, followed by the ungrateful Dazzlings. "So what’s up?" Adagio asked with a touch of irritation.

"Look, we know you’re all still mad at the Rainbooms for destroying your powers," Flash began.

Vinyl takes off her sunglasses and stares them down. "But grumbling about it is not gonna make it any better," she said, emphasizing her point with a serious look.

Adagio bared her teeth, clearly irritated. "If we still had our gem pendants--" she growled, but Flash interrupted her.

"Well, the fact is, you don’t, Adagio!" Flash snapped. "Your singing spell doesn’t matter right now. We have to make this serum to save the Girls before they release the curse!"

Adagio sneered. "Pfft. Yeah, I can’t believe you’re even in here trying to find a way to save those know-it-alls!" she said.

"They are not know-it-alls!" Vinyl retorted sharply.

Adagio, still angry, raised an eyebrow. "Really? Even Rainbow Dash?" she asked.

"You three never even bothered to get to know them!" Flash said. "But yes, Rainbow Dash is pretty annoying sometimes, but she means well. She’s sometimes just... a little irresponsible, that’s all."

Vinyl nodded, continuing the defense. "And Pinkie Pie—well, she may act crazy and wild, but she’s not dumb. She just likes to see the positive side of everything."

Flash spoke up again. "And Applejack? She’s probably the most level-headed girl we know. Even if she does tend to be a bit stubborn."

Vinyl, with a small smile, added, "Fluttershy is a bit scared at times, but that doesn’t mean she’s not comfortable joining her friends whenever they’re solving problems, no matter the risk." The Dazzlings’ expressions start to soften.

"And Rarity," Vinyl continued, "she may be a little too perfect at times, but she just wants to make sure nothing goes wrong with whatever she’s doing."

Flash’s hand rested over his heart, and with sincerity in his voice, he added, "And let’s not forget about Twilight."

Adagio, though reluctant, finally spoke. "Well... Look, we kinda cared for what you said about the first five. Although I don’t know if Princess Twilight or Sunset Shimmer are gonna make any difference." Flash and Vinyl exchanged a concerned glance at this remark.

Adagio sighed, her tone more subdued. "Look, I know. We all make the wrong choices sometimes, but if we let that stop us, we might as well lie down and give up."

"Actually, that does kinda sound like a good idea," she muttered, almost to herself. Sonata nudges her. "Too soon? Sorry," Aria admitted, embarrassed. Flash eyes Vinyl, then the Dazzlings. Adagio’s glum frown morphs into a reluctant, but supporting smile. Flash and Vinyl smile back. They all head back into the lab. Derpy and Sarah turn to face them.

"Alright, let’s get to work," Flash declared. "We have a curse to crush." Everyone immediately set to work, focused on the task at hand.
