My Little Pony Equestria Girls: Monster Mash-Up Musical

Outside the police station, the Rainbooms, the Grimwood Girls, and the Calloway Cadets stand out by the police station’s doors. Miguel hands Sibella a device. It resembles a handheld mirror with a screen, buttons, and a satellite antenna.

“This device will help you girls pinpoint the Zodiac Stone’s exact location,” Miguel explained.

Sibella presses a button. The screen zooms in on a flashing red dot, which soon becomes an image of a cave entrance.

“There it is,” Twilight said, her eyes lighting up.

Sibella studies the image before nodding. “It’s at El Cueva de las Dimensiones Elementales.”

Rainbow Dash blinks. “Wow.” She turns to Galactica. “Uh, what does that mean?”

“That’s Spanish for ‘the Cave of Element Dimensions,’” Galactica translated.

Sunset beams. “Then the stone must be inside that cave.”

Sibella looks up at the Calloway Cadets, her expression sincere. “Thanks, Cadets. First, you saved me and my friends from Revolta’s castle before it exploded, and now you’ve given us exactly what we need to find the Zodiac Stone.”

Tug smiles. “We figured you might need something extra. And don’t mention it—that’s what old friends are for.”

Sibella returns the smile. With a final grateful nod, the group turns and heads toward the parked tour bus.

“Good luck,” Tug called after them.

They waved back in appreciation as the Cadets headed back into the police station.

As the Rainbooms and the Grimwood Girls approached the bus doors, Starlight smiles in amazement. “I can’t believe it,” she said. “We got to learn more about Henry, we met the Calloway Cadets, and now we have a device that will lead us straight to the Zodiac Stone.”

Pinkie Pie grins. “Oh yeah, our luck is finally turning around!”

A familiar voice cut through the moment. “No, it’s not.”

They all turn to see Sullivan standing by the back of Minimal’s caravan! His jeep parked just a few feet away.

Rarity gasps. “Sullivan?!”

Sullivan smirks darkly. “Hello, girls.”

Rainbow Dash clenches her fists. “How did you find us?”

With a mocking chuckle, Sullivan pulls his crystal ball out of his backpack. “Uh, I’ve got a crystal ball. Hello!” He rolls his eyes before putting it back into his bag. “Now, we can do this the easy way... or the hard way.”

Twilight grins nervously. “My friends and I would like to discuss our options.”

Sullivan shakes his head, waving a finger. “Ah-ah-ah! You only have one option.” He shifts to a mocking tone. “Ex-idol jail. With stupid little bars, and a stupid little barbed wire fence, and a stupid toilet, and--” his voice turned manic. “--a stupid yard where you can lift your stupid little weights!”

Sibella shudders. “Yikes.” Then, putting on a sly smile, she steps forward protectively. “Well, if that’s true, I guess the Rainbooms are no mo--” She suddenly gasps dramatically, pointing behind Sullivan. “Oh my gosh! What is that?!”

Sullivan immediately turns in the direction she was pointing. “Huh? I don’t see anything. There’s nothing there--”

From behind him, the Rainbooms shouted in unison-- “Made you look!”

“WHAT?!” Sullivan bellowed.

He turns back to find they have already boarded. Peeking out the doors, Pinkie Pie quickly waves tauntingly before getting in. The doors close and the bus takes off. Sullivan runs forward, trying to catch up, but within seconds, he falls behind.

“ARGH! ARE YOU KIDDING ME?!” he screamed, stomping his foot in frustration.

Seething, he stomped toward his jeep, wrenched open the door, and threw himself behind the wheel. With a furious yank of his seatbelt, a jam of the key in the ignition, and a stomp on the gas, he took off after the caravan-hitched tour bus, determined not to lose them again.

The tour bus is racing down the street. Sunset is 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 sitting in Enid’s. Minimal is in her caravan trailer.

Trixie peers nervously out the window. "Do you think we lost him?"

They spot Sullivan a few feet away and belligerently following them in his jeep, racing toward them with an enraged snarl.

"Oh, no, we didn’t!" Phantasma shrieked.

The tour bus roars down the road with the jeep following them at such speed. Sitting between Twilight and Starlight, Sibella looks out the windows on the opposing side from them, and sees a stack of boulders on the edge of the cliff of a short rocky mountain slope. Sibella’s eyes tighten on the distant rocks. An idea flew into her head. She looks over to Sunset.

"Sunset, make a left turn!" Sibella suggested.

"What? But that’s the wrong--"

"Trust me. I got an idea."

Sunset hesitated, then nodded. "Okay."

Sunset veers the bus left onto a forested path. It rushes through the foliage and past a couple trees and bushes. The wheels kick up dust on the past as it rushes through. Sibella keeps an eye out. They arrive next to the mountain with the boulders on top.

“Stop, Sunset!” Sibella called.

Sunset slams the brakes, and the bus screechs to a halt.

“Everyone out!” Sibella urged.

They all rush out of the bus. Minimal comes out of her caravan. They all see Sullivan’s jeep about to turn to the dirt path in the distance.

Starlight looks at Sibella expectantly. “So, what’s the plan, Sibella?”

Sibella turns at Twilight. “Alright, Twilight, this is where you come in.”

“Me?” Twilight blinked in surprise.

Sibella nods. “Yep.” She points to the boulders. “See those rocks?” Twilight follows her gaze and gives a hesitant nod. “Use them to make a landslide. Then Rarity will use her diamond shields to send Sullivan down with them.”

Rarity nods with delight and determination. “Of course, darling!”

Twilight gulps. “A landslide? How?”

Sibella steps back with a determined look. “Arcane lightning.”

Twilight’s jaw drops. “WHAT? But you said that’s the hardest spell!”

Sibella places her hands on Twilight’s shoulders. “You are ready.” She recites the rhyming rule, “To make lightning strike so cool, one must follow every rhyming rule.” Then, with encouragement, she continued, “You need to do everything! Speak from your heart’s fire, trust yourself, focus—ALL OF IT!”

Twilight looks over at the mountain top boulders, to the distant jeep, then back to Sibella with a determined look. This was her big moment. Her time to shine. She nods bravely, then steps forward. With a look of genuine bravery, she closes her eyes and grips her wand in her right hand tightly. Spike, Sunset, Fluttershy, Pinkie Pie, Rarity, Rainbow Dash, Applejack, Starlight, and Trixie watch hopefully as a gust of wind begins to move past Twilight, making her dress and hair flow like a superhero’s cape. With her eyes still closed, the Princess of Friendship’s determined look becomes even more determined as her palms and fingers glow purple, and so does the tip of her wand. Sibella, Phantasma, Tanis, Winnie, Elsa, Matches, Enid, Galactica, Lagoona, and Minimal watch intently as Twilight’s outline begins to glow purple too. As Sullivan’s jeep races down the dirt path, Twilight stands firm. After a moment, her eyes finally snap open, now filled with BLAZING purple light. The Rainbooms and the Grimwood Girls watch with hope. With the biggest breath she had ever taken, Twilight gathers up all her energy, points her wand at the boulders... and YELLS...

VOLTAR THUNDASIR!!!

A COLOSSAL bolt of lightning shoots from her wand and BLASTS the boulders, causing an avalanche! The spell is causing a blazing light from the wand and the ground to shake. Sullivan's jeep is almost to the mountain ledge they're on. Sibella spots him approaching.

“NOW, RARITY!” Sibella shouted.

Rarity activates her geode, summoning shimmering diamond shields. With expert precision, she sends them to the other side of the avalanche and angles them downward, forming a slippery ramp leading straight into the landslide. Sullivan’s jeep hit the diamonds at full speed, the smooth surface preventing him from stopping. The vehicle swerved out of control, skidding straight into the cascading boulders! He SCREAMS on his way down. Twilight regains her ordinary posture and Rarity makes her diamond shields vanish. They watch Sullivan’s jeep tumble to the bottom of the hill beneath some trees. Everyone turns to Twilight with amazed looks.

“Twilight,” she breathed, “YOU DID IT!” She embraces her tightly, and Twilight returns the gesture. They face the group. “Did you see that, girls? The student has officially become a teacher.” Twilight grins. Sibella faces her. “I am so proud of you I could POP!”

Twilight blushes. “Oh... it was nothing.”

Sibella grins. “Come on. Back to finding that Zodiac Stone.”

They hurry back into the bus as Minimal climbs into her caravan. As they settle in, Sunset turns to Twilight with pure admiration. “Twilight! That was AMAZING! You just made the biggest lightning bolt in the history of lightning bolts!”

Twilight chuckles, her confidence soaring. “Well... I learned from the best.” She winks at Sibella, who waved her off modestly.

They all get in and the bus drives carefully down the path, and back onto the street.

At the end of the landslide, Sullivan’s crumpled jeep lies in the rocks. Sullivan himself steps out of the foliage, now even more livid, his face red, his eyes burning, his hair disheveled, his clothes a mess, and all his sanity GONE.

At the Canterlot Planetarium, in Sarah’s lab, Flash, Derpy, Vinyl, Sarah, the Dazzlings, Celestia, Luna, Cadance, and the Crusaders were still busy at work with making the anti-curse serum. Pouring liquid into a vial, Vinyl looks over to see Flash at his desk with a downcast look. Sarah is sitting beside him.

Sonata looks concerned. She leans toward her sisters, lowering her voice. “Is he okay?” she murmured to Adagio and Aria.

They follow her gaze to Flash, noting the troubled look in his eyes.

Celestia, standing near Luna and Cadance, lets out a soft sigh. “I think I should go talk to him,” she said, concerned.

But before she could move, Adagio gently holds up a hand. “No. Let me go. It’s the least I can do after he, Vinyl, and Derpy let us be a part of this.”

Celestia hesitates, then nodded in understanding.

Adagio steps forward, her shoes barely making a sound against the tiled floor. She comes to a stop beside Flash, reaching out to rest a comforting hand on his shoulder.

“Hey,” she said gently, “you doing alright?”

Flash doesn’t look up right away. His fingers tap against the desk before he finally spoke. “Just wondering what might happen to Twilight if…”

Adagio’s expression softened. “I know.” She let out a small sigh. “I know.”

A quiet moment passed between them before she continued. “Look, I hate to say this, but I’m getting kinda worried about them too.” Behind her, Sonata and Aria nodded in silent agreement. She knelt slightly to meet his gaze. “Flash, you are an amazing friend with those girls. A really good friend. And I should know because my sisters and I were bad with those girls and they hate us, not to mention let us without any magic.” She glanced at her sisters for a brief second before turning back to him. “But I just wanna let you know that Princess Twilight was lucky to have you whenever she comes to your world. You are a great friend to them, Flash. Never forget that.”

Flash finally looks up. He meets Vinyl’s gaze first, who gave him a small, encouraging smile. Then, he turned to Sarah, who nods at him reassuringly, before finally locking eyes with Adagio.

A small but genuine smile forms on his face. “Thanks, Adagio. That means a lot.”

Sarah chimes in. “So how are you feeling now?”

Flash straightens slightly. “Better. Thanks.”

Vinyl grins. “Well, that’s good to hear. Now let’s get back to work. The curse isn’t gonna break itself.”

Sarah nods. “She’s right. We still need to save the girls.”

The group shares a renewed sense of determination as they turn back to their workstations, refocusing on the mission at hand. Adagio walks back to where Sonata and Aria are standing, the two of them watching her curiously.

Aria glances at her, an uncharacteristically warm expression on her face. “That was really sweet, Adagio.”

Adagio’s lips curl into a soft smile. “Thanks.” She paused, thoughtful. “That felt kinda nice.”

The Dazzlings share a grin before getting back to work with the others. They all still needed to save Twilight and the girls before they unleased the curse.
