The Headless Horseman raced after AJ, Luna, Spike and Twilight down the halls.
"What in tarnation!? That looks like the model I helped Rarity and Pinkie build for tonight!"
"The spell must have brought it to life!" Twilight rationalized.
Luna tried blasting it with magic, but it managed to dodge.
"Just keep running!" Spike cried.
Unfortunately, as he was on horseback and the others were on foot, he was quickly gaining on them; especially the slowest of the group; Twilight. She tried running as fast as she could, only for him to ride up next to her, grab her by the arm and hold her up.
Twilight screamed as the others realized her predicament.
"TWILIGHT!" AJ and Spike cried.
The Headless Horseman lifted his sword and-
"Heads up!"
*BAM!*
"Oof!"
The Headless Horseman was hit by a blast of red magic, catching him off guard and causing his to drop Twilight.
Everybody looked and saw....
"Rainbow!"
"Pinkie!"
"Rarity!"
Indeed the trio had come to the rescue were standing there dramatically....until Pinkie clucked like a chicken.
Rainbow quickly rushed over to Twilight and grabbed her.
"Come on!" With that, everyone raced away from the now recovered Headless Horseman.
Quickly they ran until Rainbow quickly stuffed everyone inside a cleaning supply closet.
"It dark in here!"
"Oh goddess the smell!"
"Ow! Someone's on my foot!"
"I think I just stepped in a bucket."
Luna quickly hushed everyone just as they heard hoofsteps approach from the outside.
Everyone remained silent as the hoofsteps approached.....and soon passed by and faded into nothing, causing them to give a collective sigh of relief. They quickly stumbled back into the now empty hallway.
"I'm so glad you guys are alright!" Pinkie said, trying to shake the bucket off her foot.
"What in the world in going on!?" Twilight asked. "We sensed a magical disturbance coming from the school and came to investigate."
"Well I believe Rainbow Dash can explain." Rarity said with a pointed glare.
Rainbow herself just gave a nervous grin. "Hehe...well...you see....."
"...and that's when we came to find you guys."
Rainbow finished her explanation with another nervous grin....which contrasted with the rather stern glare from Luna.
"So to summarize; you borrowed an old spell book when I told you not to, used a spell you have never used before unauthorized and put several people in danger just because you wanted show up Trixie?" Luna asked, still glaring.
"...yes?" Rainbow said, her nervous smile growing.
AJ just rubbed her eyes in annoyance. "Rainbow Dash what were ya thinkin'!?"
"I just wanted to make this night scary and fun for everyone!"
"Well congratulations." Twilight replied sarcastically. "You've certainly succeeded in making this night 'scary', but I think the 'fun' part is debatable."
"We'll finish this discussion later." Luna said. "Now show me the spell you used so I can reverse this."
Defeated, Rainbow dug into her bag and pulled out the book before flipping to the correct spell. She handed it to Luna who gave it a quick look over.
"Rainbow....are you aware of what this spell does?" She asked too calmly.
"Uhh....make everything feel like a real horror house?"
Luna looked at her. "No. It actually turns everything into a horror house."
"What!? Where does it say that!?"
"Right after the spell."
"Why would you put something like that after the spell? If it's so important, why not put the warning before the actual thing!?"
"Thankfully the reversal spell is right-"
In the blink of an eye, a little bed sheet ghost popped up in front of Luna, grabbed the book, and flew off giggling down the hall.
Everyone just stood there, stunned for a few seconds before--
"After it!" Pinkie commanded before everyone gave chase.
Once they turned the corner however, several screams could be heard.
"Oh no! That must be the others!" Rarity realized.
"We have to help them!" Rainbow was about to run off before being grabbed by Twilight.
"But we have to get the book back!"
"Especially before midnight." Luna stated.
Rainbow looked confused. "What does midnight have to do with anything?"
At this, everyone just groaned and either rolled their eyes or face palmed.
"Did you even pay attention to yesterday's lesson?" Luna asked sharply.
"Uhh...for the most part?"
"Was it the part where I told you that Nightmare Night is an especially important night because any spell casted on that day and not reversed before midnight becomes permanent?."
"WHAT!?"
"Ya see? This is why you should pay more attention in class!" AJ scolded.
Rarity checked her phone and gasped. "But that gives us less than an hour!"
"But what about the kids?" Pinkie asked. "Sunset and their parents will KILL me if anything happens to them!"
"Alright everyone." Twilight said. "Pinkie, AJ and Rarity: you go and protect the group while Luna, Spike, and Rainbow and myself will try to get the book back. Agreed?"
Several nods and "yes"s replied back.
"Good. Now let's go! If we don't reverse the spell before midnight, we'll be stuck with a school of horrors!"
With that, the two teams split up to save the day!
Hopefully.
