In the dead of night, thunder was heard crashing at Pinkie’s house as the party girl was tossing and turning in her bed.
"Looks like my favorite playmate is here." A dark voice evilly chuckled while in Pinkie’s dreams, she was running from something in the darkness. "You can run, but you can't hide." The dark voice provoked as Pinkie stopped and turned around, trying to bring out her weapon, but it was gone! "You honestly think you can fight me? This is too much!" The dark voice mocked as Pinkie realized that her geode was gone too! "You could never get me for years. I'll always be here to make YOU SCREAM!"
"No! No! Get away! Stay away from me!" Pinkie screamed as dark voice showed his eyes and mouth before his laughter got louder and louder, causing Pinkie to wake up in a terrified state. "Why… *Sniff!* Why is he back…?"
Pinkie’s bedroom door opened, revealing her big sister Maud. "Him again?"
"He was gone for months… but why come back now?" Pinkie whimpered as Maud hugged her.
"He’s just a bully, Pinkie. I know you can stand up to him." Maud gently chided as Pinkie hugged back with tears of fear and sadness.
Months later, Aria sat sadly on a rooftop staring at the skeleton key she had. "So much for that idea… Even Halloween was a no-go."
"Hey Aria, you okay?" Mikey asked as he, Pinkie and Rainbow Dash showed up.
"No." Aria answered before Rainbow Dash snatched her key away.
"What's this?" Rainbow Dash asked.
"Hey! It’s important!" Aria shouted.
"Halloween is over, Aria." Pinkie said as three noticed Pinkie’s mood while the Crusaders showed up.
"You okay, Pinkie? You look like you had better nights." Aria asked.
"I don't want to talk about it." Pinkie answered while no one noticed the key sucking the Equestria magic from Rainbow Dash and her.
"Scoots? What’re you and the other Crusaders doing here?" Rainbow Dash noticed.
"Rarity is busy with a fashion show." Sweetie Belle responded.
"And Applejack is doing something important she couldn't explain." Apple Bloom added.
"So we thought we'd hang out with you guys." Scootaloo finished.
"Oh. Cool." Rainbow Dash noted.
"That's cool. Can I have my key back?" Aria asked.
"Sure… after you explain why you have something like this. Just wanna know, not being suspicious." Rainbow Dash replied.
"I will. Just be careful with it." Aria said before she and the others heard a click, before a jack-o lantern-shaped door with the nose as the doorknob appeared on a wall, before Rainbow Dash dropped the key in shock.
"What the?!" Rainbow Dash gasped.
"Oh, NOW it works?" Aria noted before the key shattered on impact with the ground. "NO!!!"
The door on the wall opened, revealing a portal as it sucked them in, before it closed after the group of seven were gone as the door disappeared.
Later, Rainbow Dash was the first one to regain consciousness. "Everyone okay?"
"Ugh… Yeah." Aria answered.
"Phew! That’s good to… hear…" Rainbow Dash trailed off while Aria found her gift scythe in the ground.
"Phew! It’s here!" Aria sighed in relief before Rainbow Dash screamed in horror, waking the others up. "What's wrong?"
The others raised their weapons against each other, much to Aria’s shock.
"Guys?" Pinkie noticed.
"Huh?" Mikey wondered in confusion.
"What the..." Rainbow Dash gasped.
"What happened to us? Why do we look like monsters?" Scootaloo asked.
"I’m not sure-Whoa!" Sweetie Belle yelped as her head fell off of her body.
"Sweetie Belle!" Apple Bloom shouted in horror.
"Your head just fell off!" Scootaloo gasped in shock.
"But… I feel perfectly fine." Sweetie Belle noticed while her body lifted its hands up, only to not feel a head on her shoulders and started looking around, before Sweetie Belle screamed. "Put me back on me!"
"Sure thing." Aria said before everyone saw her Gorgon body.
"Gorgon!!!" Scootaloo screamed as she and the others except Aria closed their eyes, as the siren was revealed to be turned into a woman with purple and turquoise snakes for hair and a purple serpent tail in place of her legs, making her shape like a Lamia.
"Oh, how I missed this body." Aria sighed in happiness.
"Huh?" The others wondered in confusion as Aria brought out a pair of sunglasses before putting them on her face.
"It’s okay guys, my glare only paralyzes others, not turns them into stone. And Rainbow Dash, thanks for getting me these sunglasses, so that way, my glare won’t have much of an effect at all." Aria explained.
"What's going on?" Rainbow Dash asked.
"Oh, it’s just that me and my sisters have been here before, with Adagio being a Phoenix and Sonata being a Scylla, while I’m a Medusa. And if this place is what I think it is, then we’ll be in for a scary-fun time!" Aria answered.
"Well, what are the rest of us?" Pinkie added.
"Well Pinkie, you’re a Bride of Frankenstein, but it’s only the appearance and additional abilities. Mikey is a combination of his mutant self and a werewolf. Rainbow Dash is a ghost, so she can fly and become invisible or intangible. Sweetie Belle is a Dullahan, which is the combination of a headless horseman and a reaper. Apple Bloom is an Anubis, which explains the jackal fur, ears, nose and claws. And Scootaloo is a vampire, so she can turn into a bat or into mist to fly through the air and cracks." Aria informed as Rainbow Dash looked at her body.
"Whoa!" Rainbow Dash gasped in awe as Pinkie started generating electricity.
"Ooh! Sparky!" Pinkie awed in amazement as Mikey looked at himself.
"Dude! Fur and scales?! Awesome!" Mikey cheered in excitement as Apple Bloom started sniffing.
"Why do Ah have a sudden hankering for bones?" Apple Bloom noticed.
"At least your's is clean." Scootaloo responded while Aria spotted a familiar skeleton sneaking around.
"Me and the girls came here for a little spooky fun over the years. Made a lot of good friends that just want to make you… SCREAM!" Aria shouted before the skeleton leapt out and roared right behind Rainbow Dash, Pinkie, Mikey and the Crusaders, scaring them a ton, before the six heard Aria laughing from that. "Still got it after all this time, Jackie!"
"Oh, how I've missed our team-up frights, Aria." The skeleton happily said.
"You and me both." Aria agreed before she and the skeleton hugged. "Oh! And I got you something." Aria added as she gave the skeleton the scythe.
"This is perfect!" The skeleton said with excitement after an intrigued gasp before Aria noticed something on the his right wrist.
"That's a weird bracelet." Aria noted.
"Oh, this is the Soul Robber! I’m actually looking for new things to make Halloween scarier than ever before! And I was on my way back to Halloween Town. Wanna come along?" The skeleton offered.
"Sure, but first let me introduce my friends." Aria said as she turned to Rainbow Dash and the others. "Everyone, calm down. Jack looks scary but he’s harmless. He wouldn’t hurt a fly."
"Not completely true if it involves a certain fly." Jack corrected.
"Good point. Especially since the four of us fought him for the first time." Aria agreed.
"Hi, I'm Pinkie Pie." Pinkie introduced herself.
"I’m Mikey." Mikey said.
"I'm Rainbow Dash." Rainbow Dash added.
"I’m Scootaloo." Scootaloo continued.
"Ah'm Apple Bloom." Apple Bloom greeted.
"And I’m Sweetie Belle." Sweetie Belle finished.
"Where's Adagio and Sonata?" Jack asked.
"Back home. But they’ll be so excited when-Oh wait… The key got destroyed to get us here." Aria remembered.
"Not to worry. The doctor can make a new one." Jack responded.
"Thanks, Jack." Aria said in gratitude.
"Hey, he looks like the skeleton from the news." Pinkie noticed.
"Huh?" The other ninjas wondered in confusion.
"Oops!" Jack dreaded.
"Jack, what is she talking about?" Aria asked.
"Remember Christmas two years ago?" Jack replied.
"Yeah." Aria answered.
"That skeleton… That was me." Jack said before Aria hit him hard on the face, causing his head to spin before he stopped it. "Yep. I deserved that."
"How could you do something so stupid?!" Aria asked in frustration.
"I didn’t know about the other Holidays, and I thought that I could give one a try." Jack explained.
"Dude, you caused a major panic!" Mikey pointed out.
"Yeah, and I realized what a terrible mess I made. So I went back home to get Sandy Claws back, only to find out that he had been captured." Jack added.
"I have a pretty good idea by who did that." Aria noted.
"Good. But I managed to beat him and save Sandy Claws and apologize for the disaster I caused." Jack finished.
"At least you learned your lesson." Aria responded.
"And Sandy Claws saved Christmas." Jack added.
"So, where's town?" Rainbow Dash asked.
"I can lead you there." Jack offered.
"Lead the way." Pinkie said as she and the others followed Jack.
Meanwhile, inside a hidden lair...
"Where is she?!" The dark voice from before asked.
"Where is who?" A young boy in a devil mask and costume responded in confusion.
"That pink baby!" The dark voice answered.
"You can't find her?" A young girl in a witch mask and costume asked.
"Yes!!! And that means that she’s with that goody two-bones Jack Skellington!" The dark voice realized.
"So what? She's utterly terrified of you so it’s not like she'll want to fight you." A young boy in a skeleton mask and costume pointed out before he and the other two flinched, thinking they'll get hit.
"You know what? You're right." The dark voice noticed.
"Huh?" The three masked children asked in confusion.
"She's so scared of me, I don't need to even try fighting her." The dark voice said.
"Nice save there." The devil-costumed boy admitted.
"Hehehe! But not fighting her doesn’t mean I can’t still haunt her." The dark figure laughed.
"Can we hurt her?" The witch-costumed girl asked.
"Anything that scares her!" The dark voice confirmed as his figure flipped a switch. "Let the nightmare begin!" The dark figure declared as it laughed maniacally.
