My Little Pony: Equestria Girls: Canterlot High’s Halloween Party Hijinks (AKA: CHS’s Halloween Party Hijinks or Canterlot City’s Halloween Party Hijinks)

Somewhere downstairs in the main hall, the rainbooms and the Shadowbolts were still screaming in fear and rushed over to Principals Celestia, Vice Principal Luna and Principal Cadance who were dressed as Princesses, including Canter Zoom.

“A REAL LIVE GHOST!! UPSTAIRS!!” cried Indigo in fear.

The Principals looked very serious and stern at what the girls saw thinking that the girls were doing their pranks here.

“Girls, this isn't the time or place for your silly pranks.” said Principal Cadence in disbelief.

“Yeah, This is never the time or place here!” Vice Principal Luna said.

“It’s not a prank, ma’am!” Sunset said, honestly.

“Really, it’s not a prank!” agreed Sci-Twi.

“No, We were upstairs pulling a prank on the Shadowbolts…” Rainbow explained about what happened.

“...and we were pulling a prank on the Rainbooms and their friends…” Lemon continued.

“Girls, what have I told you about…” Celestia said.

Meanwhile in the attic, a mother and father ghost are talking to their son ghost, having removed his jack-o-lantern disguise.

“...playing pranks on people?” the ghost father asked as the son gave back the pumpkin to him.

“That it's mean-spirited and it always comes back to haunt you.” the ghost boy answered.

“Because when pranks get out of hand, someone could get hurt and their feelings are sure to get hurt.” The ghost father explained.

“The girl with the green wig who wears the orange necklace with the sun (Sunset), including her twin friends (Princess Twilight & Sci-Twi) and the pink haired girl (Pinkie) asked me to help them. Besides, I just wanted to go to the party.” The ghost boy said.

“There are better ways to have fun.” The Ghost father explained as the Rainbooms (plus Princess Twilight, Trixie, Starlight and the two Spikes) and the Shadowbolts apologize to the principals and Canter Zoom

“We’re sorry. Principal Cadence.” Indigo said.

“I’m sorry too.” Sunny said.

“I’m sure this won’t happen again.” Lemon said.

“Same here.” Sugarcoat said.

“I owe you an apology too.” Sour said.

“We’re very sorry. Principal Celestia & Vice Principal Luna.” Sunset apologized.

“I’m sure we won’t do pranks again. Honest.” promised Applejack.

“We’ll never prank those girls EVER again.” Rainbow said.

“Besides, we won’t hurt anyone’s feelings again.” Rarity said.

“EVER again.” Fluttershy replied.

“I promise not to pull a prank on someone ever again and never make it out of control!” Pinkie said.

“Same here.” Sci-Twi said.

“I’m with her.” Princess Twilight said.

“I hate to say this, but I’m sticking with the girls. I apologize.” Starlight said.

“But there really was a gho---.” Indigo continued as she got interrupted.

“No more. Go have fun.” Principal Celestia said, as the girls all walk off together.

“Man, am I ever done with pranks. I don't care how much you prank me.” Indigo said to Sunset.

“Yeah, glad we learned a lesson ourselves, thanks to our Principals.” Sunset said.

“I'm not pranking anyone, ever.” Applejack said.

“EVER, EVER?” The girls asked.

“Yup.” Applejack responded.

Meanwhile, Flash Sentry (who is dressed up as Kai from Ninjago) and Wallflower Blush (who is dressed up as Betsy Bubblegum from Yummi-Land), walks up to the Ghost boy and his family who are standing at the buffet, looking very impressed at their costumes.

“Hey, cool costume.” Flash said, looking impressed.

“It looks too thrilling.” said Wallflower.

“Thanks. Yours is cool, too.” replies the ghost boy.

“Thanks.” Flash replied.

“Thanks.” Wallflower replied as the two walked away.

Just as the 2 humans walked away, the ghost boy pointed at his father, that he's floating too high, almost exposing his identity.
“Oops!” said the Ghost Father, almost accidentally exposing his true identity as he floats back down to ground shielding his invisible legs. He puts an arm around her son and winks at him.

With that, everything was back to the way it was. Everyone was having a good time at the party, dancing, watching the Shining and having a great Halloween everyone has ever had. Most of all the Rainbooms and The Shadowbolts have learned a valuable lesson; “You should never pull pranks on a party, cause’ these pranks can get out of control and someone’s feelings can get hurt, but there are better ways to have fun at the party (not by pranking guests, but by hanging out and socializing with them).
