My Little Pony Equestria Girls: Monster Mash-Up Musical

In Mr. Mysterio’s backyard, enjoying the party, are 3 of the world’s most famous monsters: the Loch Ness Monster, Bigfoot, and the Abominable Snowman. Mr. Mysterio leads the Rainbooms and the Grimwood Girls outside. Twilight’s eating a slice of pizza, Sunset - a B.L.T. sandwich, and Starlight - a piece of cake. The Rainbooms are amazed by the 3 famous creatures at the party.

"Whoa! Three of the biggest monster legends ever!" Pinkie Pie exclaimed, her eyes wide with excitement.

Rainbow Dash grins. "The Abominable Snowman! Bigfoot!"

Applejack grins ear-to-ear. "The Loch Ness Monster?! Yee-hoo! She’s one of the big ones!"

In the pool, the Loch Ness Monster (Nessie) turns to face the Rainbooms. She smiles sweetly. "Well, as I live and breathe. If it isn’t the Rainbooms."

Sunset smiles, starstruck. "Ms. Nessie, it is such an honor--"

Nessie chuckles. "Oh, and I see you’ve gone all-out with costumes, or should I say, transformations this year."

Bigfoot (Biggie) nods approvingly. "Whoa, I gotta say, you ladies look amazing."

The Abominable Snowman (Yeti) grins. "Not to mention, spooooooky."

Rarity laughs softly, gazing down at her mummy form. "Well, thank you. I admit, it so does not hurt."

Examining her ghost form, Fluttershy gives a small smile. "Makes me feel braver and more powerful."

As the Rainbooms continue to chat with the famous monsters, Enid and Sunset spot the gas pump close to the fence. With Enid holding the gas can, they head up to it, Enid take the nozzle off the gas can, and Sunset pumps gas into the gas can. At the back porch, Twilight and Sibella face Mr. Mysterio.

"So, Twilight," Mr. Mysterio began, his voice warm and friendly, "Sibella’s teaching you how to use your new witch magic."

Twilight smiles. "I did pretty good with the levitation spell. The growth spell, well, I’ll focus harder on that one next time."

Mr. Mysterio gave a reassuring smile. "Oh, I know you will." He turns to Sibella. "And Sibella, I can’t believe you kept your spell book even after you graduated. Grim would have been proud." Sibella blushes sweetly.

"So, how’s everything going at Ghouls Funland?" Mr. Mysterio asked curiously.

Sibella beams. "Going fangtastic! Things have never been better at Monsterdom since we opened up Ghouls Funland. And things at Grimwood Manor are still running as smooth as ectoplasm. We wouldn’t want to live anywhere else."

Before she could say anything else, a voice rang out from behind them. "Hey, Sibella."

Sibella immediately becomes irritated. "Except a place without him," she muttered under her breath.

Henry emerges from the sliding glass door, wheeling a moving cart carrying 3 objects covered in tarps. The Grimwood Girls take notice. So do the Rainbooms. Sunset finishes pumping gas into the now full can.

"Evening, Sibella. Sup, Twilight?" Henry said, giving a lazy wave. Sibella raised an eyebrow, Twilight looked more alert, and the Grimwood Girls and Rainbooms all took a step closer.

"Grimwoods. Rainbooms," Henry greeted them casually.

Overlapping:
"Hello?" Spike responded in confusion.
"Hey…" Starlight murmured, uncertain what to make of Henry’s sudden appearance.
"Hi?" Sunset added, eyeing Henry with suspicion.

Sibella crosses her arms, her tone sharp. "What do you want, Henry?"

Henry grins widely, clearly amused with himself. "Well, I know I never got to rescue you from Sullivan’s henchmen back at Revolta’s lair, so I thought this would make up for it." The Rainbooms and the Grimwood Girls gather around. Henry shows his cart. "Welcome to Henry’s House of Horror! Everything in the world that I find horrifying!"

Enid raises an eyebrow. "Okay. Let’s see what you got."

With a smug smile, Henry begins unveiling his "horrifying" items. "First..." He removes the tarp from the first object, revealing an old math test, graded with a B, placed on a stand. "An old math test!" Twilight and Sunset look at each other, bewildered. Sibella looks downright uncomfortable. "Next..." Henry pulled the tarp off a second object: a potato sitting atop a pedestal. "A potato whose eyes follow you, no matter where you go!" Spike and Matches look puzzled. Enid is pretty unsure. They were all more confused than scared. "And finally, the most horrifying of all..." Henry dramatically removes the tarp from the third and final item: a plastic yard statue of Santa Claus. The group stares at it, more bemused than terrified. Sunset shakes her head in exasperation.

"Henry, no one thinks Santa’s scary," she said with a sigh.

Henry’s expression falters. "Are you kidding? A strange man who breaks into your house in the middle of the night and steals your cookies? No, thank you."

"Shh! Henry! He’s watching!" Rarity gasped.

Everyone turned toward the plastic Santa. Henry, now feeling a bit embarrassed, awkwardly addressed the statue. "He is?"

"Yeah," Rainbow Dash confirmed. "He sees you when you’re sleeping, and he knows when you’re awake."

Henry’s eyes widened in realization. "Oh." He turned back to the plastic Santa. "Sorry, Santa." He quickly backed away, looking sheepish. "I’m just gonna go now."

Henry leaves and Sibella rolls her eyes, facepalming. "House of Horror? More like house of how-is-that-scary."

Twilight chuckles, trying to lighten the mood. "Don’t let it bother you, Sibella. I was just thinking, maybe a song could get your mind off it."

Sibella, though still a little irritated, gives a small nod. "You might be right, Twilight."

Nessie, hearing the conversation, called out excitedly, "Oh! Yeti, Biggie, we’re about to see the Rainbooms perform a song in person!"

Yeti and Biggie are thrilled. "AWESOME!" they both shouted in unison.

Twilight and Sibella share a grin.

Later, the Rainbooms had their instruments set up on a stage in the backyard. Twilight’s at the microphone, Sunset: her acoustic guitar, Fluttershy: her tambourine, Pinkie Pie: her drum set, Rarity: her keytar, Rainbow Dash is on her electric guitar, Applejack: her bass guitar, Starlight: her keyboard, and Trixie: her v-neck guitar. Spike and Matches are back-up dancers. The Grimwood Girls are back-up singers. Mr. Mysterio, Nessie, Biggie and Yeti watch them. They start singing and dancing.

TWILIGHT SPARKLE:
We get it almost every night
When that moon gets so big and bright

(Cut to the entrance of the neighborhood as the song continues. Sullivan strolls down the sidewalks with 5 of his henchmen. They hear the Rainbooms’ singing.)

TWILIGHT SPARKLE, SPIKE, SUNSET SHIMMER, SPIKE, and ENID:
It's such a fun and natural sight
Everybody was dancing in the moonlight.

As the song came to an end, the backyard bursts into applause. Mr. Mysterio claps enthusiastically. "Amazing!"

Nessie beams, nodding her approval. "Bravo!"

Bigfoot gives a hearty cheer. "That was amazing!"

Yeti adds with a wide grin, "Fantastic!"

The Rainbooms and the Grimwood Girls smile. At the front door, Sullivan bursts into Mr. Mysterio’s house with his henchmen. In the backyard, as the Rainbooms and the Grimwood Girls take in the applause on the stage, Twilight and Sibella notice Sullivan in the house through the sliding glass door. Inside, Sullivan gives them an evil smirk.

“Oh, it’s on!” he declared.

Twilight’s eyes widened, and she turned to Sibella. "Uh-oh," the vampire muttered.

"Uh, girls?" Twilight called out to the others. "We’ve got a problem."

The other Rainbooms and Grimwoods take notice just as Sullivan and his henchmen come outside through the forcefully-opened sliding glass door. The Rainbooms, Grimwood Girls, Mr. Mysterio, and the 3 legendary monsters gaze at them wide-eyed. Enid uses her wand to teleport the Rainbooms instruments back to the tour bus. Mr. Mysterio glowers at Sullivan. He gets out of his seat and storms up to him.

"Well, that was rude," Mr. Mysterio said, insulted. "Barging in uninvited to a house party--"

"Out of my way, old man," Sullivan growled.

Mr. Mysterio didn’t flinch but shot back with fiery defiance. "Hey! Respect your elders, you ruff--" He stopped mid-sentence, realizing that Sullivan was staring at him with a glare that could melt steel. "Never mind," he muttered.

Sullivan walks menacingly to the stage, then his eyes go wide. The Rainbooms and the Grimwood Girls are gone. "What the--?!" Looking really peeved, Sullivan turns back to Mr. Mysterio’s direction. "Alright, you magic weirdo. Where are the Rai--?" He finds Mr. Mysterio gone too. "Ugh!" he growled, even madder.

In the house, the Rainbooms and the Grimwood Girls were telling Mr. Mysterio about Sullivan. "So we have to get to the stone before Scarface, and before Sullivan gets his hands on the Rainbooms," Sibella said to Mr. Mysterio quietly and urgently.

Mr. Mysterio's eyes go wide. "Out for revenge, huh? Well, there’s anything I hate, it’s corrupted humans out for revenge against their former idols."

Back outside, Sullivan glared at the three legendary monsters, who were trying their best to feign ignorance. "Alright, you three!" Sullivan barked. "Where are the Rainbooms?! Where are my runaways?!"

Nessie, Biggie, and Yeti pretend to be confused to protect the Rainbooms and the Grimwood Girls.

"Hmm. The Rainbooms? I never heard of them before in my life," Nessie said innocently. "Biggie? Yeti?"

Bigfoot shrugs, playing along. "Nope."

"Neither have I," Yeti added.

On the front porch, Mr. Mysterio faces the Rainbooms and the Grimwood Girls. Sibella holds the now full gas can and Twilight holds a bag of snacks from the party.

"Alright, you girls go," Mr. Mysterio said firmly. "I'll distract them long enough for you to get a head start."

"Thanks, Mr. Mysterio," Enid said with a grateful smile.

"And thanks for the gas," Sibella added, holding up the can.

Twilight nods. "And the snacks."

Mr. Mysterio gave them a warm smile. "Anytime. Good luck finding the Zodiac Stone."

The Rainbooms and the Grimwoods rush away from the house. Mr. Mysterio waves after them, then rushes back into his house. Sullivan comes in through the sliding glass door and faces Mr. Mysterio. "Now, where were we?" the old man said.

Sullivan, clearly annoyed, snaps, "Lister, mister. We are NOT leaving until--!"

"I show you the house. Of course," Mr. Mysterio interrupted, pushing Sullivan aside with surprising force.

Elsewhere, the Rainbooms and the Grimwood Girls arrive back at the Rainbooms’ tour bus. Pinkie Pie turns to the Grimwood Girls with a worried look. "You think it was a good idea to leave Mr. Mysterio to deal with Sullivan?"

"Don’t worry, Pinkie Pie. Mr. Mysterio may be old, but his will is strong, and his magic is still very powerful," Phantasma said reassuringly.

Sunset starts filling the bus’ tank up with gas using the gas can. In the backyard of Mr. Mysterio’s house, Nessie, Biggie, Yeti, and Mr. Mysterio himself all stand by a shack. 4 of Sullivan’s henchmen are tied up nearby. "What do you mean the door is stuck?" he asked, pointing to the hole where the door’s knob should be. "Try wriggling the knob."

Inside the shack is Sullivan and the fifth henchman. Only their eyes appear in the pitch black darkness.

"There is no knob in here!" Sullivan growled, his patience wearing thin.

Mr. Mysterio, holding the knob sneakily outside the shack, feigned surprise. "There’s not? Are you sure?"

Sullivan growled again, his temper snapping. "Alright, I’ve had enough of this! Tell me where the Rain-bores are, and there will be consequences."

"Uh, don’t you mean 'or'?" the henchman corrected.

Sullivan glared at the henchman, then turned back to the hole in the door where the knob should be. "Tell me where the Rain-bores are," he growled, "OR--" He emphasized the conjunction with a glare, "there will be consequences."

"Well, which is it?" Nessie asked innocently. "That seems like a pretty crucial conjunction."

"Ugh! That’s it!” Sullivan snarled furiously. "Break the door down!"

"Break it down?" The henchman asked, bewildered. "Are you kidding me? This is hand-carved mahogany."

"I don’t care!" Sullivan barked stubbornly. "Get out of my way! I’ll break it down myself!"

Mr. Mysterio, Nessie, Bigfoot, and Yeti waited just outside as Sullivan started counting from inside the shack. "One…"

Mr. Mysterio signals to the others. "Alright, guys. You know what to do."

"Two…" Sullivan continued.

"Right!" Nessie, Bigfoot, and Yeti said in unison before scampering off just as Mr. Mysterio slid the knob into the hole.

"Three!" Sullivan shouted. Mr. Mysterio opens the door just as Sullivan charges through it, but crashes through a pile of leaves set up by Biggie, then slips onto an ice slide that was quickly formed by Yeti. At the end of the slide, Sullivan flies up then Nessie hits him with her tail like a baseball bat, sending him landing in a fish pond on the other side of the fence. Sullivan’s seething, raging, angry face rises from the water and he climbs out. He stomps back to the jet plane. The 5 henchmen that went with him follow him from the backyard. Nessie, Biggie, and Yeti watch with Mr. Mysterio, who gazes off in the direction he saw the girls went.

"Rainbooms, Grimwood Girls," he murmured quietly, "Take good care now. All my hopes fly with you."
