It was Nightmare Night and the mane six have to dress up in their costumes for the special night. Twilight is a witch, Pinkie is a clown, Rarity is a princess, Fluttershy is a bunny rabbit, Rainbow Dash is Peter Pan, and Applejack is a Viking.

"What do you think of my glorious costume? Made it myself." said Rarity. "It sure is beautiful, Rarity. Thanks for the costumes for us." said Twilight. "Yeah, this Peter Pan costume really works out on me. It's even better than my shadow bolt costume." said Rainbow Dash. "It'll be cooler if I'm a scary clown instead of a normal clown. But, it's fine." said Pinkie. "Do you think my bunny costume will be ok for the festival? I don't want any pony to laugh at me." Fluttershy asked. "No pony will ever make fun of your costume, Fluttershy. Plus, it's Nightmare Night. You get to be whatever you want. You wanted to be a bunny, so that's that." Applejack explained. "Come on, girls. Let's eat some sweets!" said Pinkie.

...

As they were about to go out for the festival, the Book of Disney was calling them, making the mane six groan in annoyance.

"Come on, Book of Disney. You're killing us here." Rainbow Dash complained. The mane six went to the book and Twilight opened it to the next chapter. The next story is The Nightmare Before Christmas. She began to read,

"Once upon a time in Halloweentown lived the pumpkin king, Jack Skellington. He's the one who's in charge to make plans for Halloween every year. This makes him sad and bored because he wants to do something new for Halloween. Something that no one has ever done. So, he decided to change things a little bit by going to Christmastown. But Jack doesn't know that taking someone else's holiday is wrong."

Once Twilight is done reading, the mane six got sucked in by the Book of Disney.

...

They appeared in the woods with trees who have holiday symbols on them.

"Where in the hay are we?" Applejack asked. "Aren't we supposed to be in Halloweentown?" Rainbow Dash asked. "I'm not sure. We are supposed to find Jack since he was here." Twilight explained. "Hm, I think these objects on the trees are doors. Don't you see the knobs?" said Rarity.

Twilight looked at each door and said, "You're right. Jack must've opened one of these doors. Now, we gotta find the one that says Christmastown." Pinkie looked at them, but got distracted when she saw a door with a green tree covered with decorations. "Hey girls, do you think Jack went into this door?" she asked. "I don't know, Pinkie. Are we supposed to go in there to see?" Fluttershy asked.

"Well, there's only one way to find out." said Twilight as she opened the door with her magic. When she did, the mane six peeked inside and sees nothing. "Heh, I don't see anything. Maybe we're at the wrong place." said Rainbow Dash. But, she was wrong.

Snowflakes and a powerful wind surrounded them and pushed them all inside. And the door shuts behind them.

"Whoa!" Twilight yelled. "AHHHHHH!" Pinkie screamed. "What in tarnation?!" Applejack yelled. "Oh my gosh! I'm getting dizzy!" Rarity shouted. "What's going on!?" Rainbow Dash shouted. "Somebody help us!" Fluttershy yelled.

...

The girls stopped spinning and lands on a pile of snow.

"Snow?" Applejack asked herself as she picks up some of it. "Oh my goodness. That was irritating when I got spun around." Rarity complained as she dusts off her costume and hat. "Where are we?" Fluttershy.

Pinkie and Twilight looked around and saw a town full of lights. "Wow, this is the beautiful town I've ever seen!" Pinkie said. "Girls. I think we made it." said Twilight. "We are?" Rainbow Dash asked as she looked at the town too. "Holy Celestia!" said Applejack. "No wonder why Jack went here." said Rarity. "Then, let's find him." said Fluttershy.

They explored the town as they looked for Jack. Pinkie immediately loved this place because it's filled with happiness and joy, plus it's part of her nature. What she likes most are the gingerbread houses. "This place is amazing! I wish we have this in Equestria!" she said. "I like this place too, Pinkie. And who's that really tall guy with a skeleton head?" Rainbow Dash asked as she looks at the guy who's gathering Christmas items to his wagon. Twilight sees him too and guessed, "It must be Jack Skellington. Let's go check."

She walked to him and tapped his shoulder. Jack turned around and got startled. "Oh, you startled me. You know, scaring people is my thing. By the way, are you girls wearing costumes? They're stupendous." he said. "Thanks. Are you Jack Skellington?" Twilight asked. "Why, yes I am. Jack Skellington, the Pumpkin King!" Jack answered. "And who are you since you startled me?" "I'm Twilight Sparkle and these are my friends. Rainbow Dash, Pinkie Pie, Applejack, Fluttershy and Rarity." Twilight introduced.

"Heard you wanted to do something different for Halloween and you're taking these stuff from this place why?" Applejack asked. "So, I can show my friends this stuff and do something diffrent around here. Plus, I heard about the guy running the place. Sandy Claws." Jack explained. "Sandy Claws? I've never heard of him." said Rarity. "Well, now you do. Come on, girls. We have some planning to do." said Jack as he gathered the last Christmas item in his wagon.

He and the mane six left Christmastown and went off to Halloweentown.

...

When they got there, the ghouls who live there were staring at them like theyre curious about them. This scares Fluttershy that she hides in the wagon.

"Why are they staring at us like that?" Applejack asked. "That's because they've never seen you before. Don't worry, I'll tell them you're friendly." said Jack. "Well, can they stop? It's creeping me out." said Fluttershy.

The mayor of Halloweentown arrived in front of them and said, "Jack, there you are. I've been looking for you all day. Where have you been?" "Mayor, I have discovered a new way for Halloween and would like to have a meeting about this." Jack explained. "Whe?" Mayor asked. "Immediately. And these girls are going to help me with this. Wouldn't that be exciting?" Jack answered.

"Sure, Jack. But, I'm not sure they like it or not." said Twilight. "Do you think Sandy Claws would mind if we do this?" Rainbow Dash asked in worrisome. "Don't worry, girls. I'm sure everything will be just fine." Jack promised.

This makes the mane six worried about the meeting.

...

Later that night, they were all invited to Jack's meeting along the other ghouls, including a rag doll named Sally.

The mane six sat in the front while they wait for Jack to be on stage. The mayor went on stage and spoke on the microphone, "Good evening, ladies and gentlemen. I'm so glad you could all join us on a special night. Now, Jack has something for us to share with him. Without further a do, may I present Jack Skellington." The audience cheered as Jack appeared onto the stage.

"Thank you, mayor. And thank you everyone for joining me on this wonderful night. Now, the main reason I called you all here is because of this." Jack introduced as he opens the curtain to reveal Christmas stuff he got from Christmastown. The audience and the mane six were amazed by the colors and the wonder.

"Yes, I know you're excited as I am. This is called Christmas." "What does it do?" a monster asked. "We celebrate it, of course. This box I'm holding is called a present. Children open it and get a toy for being good." Jack explained. "Does it hold potions and dead things?" a witch asked. "No. They hold toys. Oh, and I haven't told you the best part about Christmas. The ruler of the town. He is called Sandy Claws." Jack answered in a sinister voice.

The audience cheered for him.

...

Later on, Jack is discovering what Christmas really means. Twilight tried to explain to him, but he's too busy doing science experiments and reading books about Christmas.

His anxiousness makes everyone else worried about him. "What does it mean? What does it mean?" he said to himself. "Um, can we help you with that?" Fluttershy asked. "Thanks for volunteering, but I have to do this alone. I'm the one who got the idea, so I have to plan all of it one by one." Jack explained. "So, what are planning?" Pinkie asked.

"Im planning to be like Sandy Claws. Like riding on a sleigh, having reindeer, giving presents to children." Jack answered. "Um, Jack. Isn't that his thing? I mean, your thing is to scare people during Halloween." Twilight explained. "Plus, he's not sick or anything." said Applejack. "Isn't Christmas supposed to be a happy holiday, not a scary holiday?" Fluttershy asked. "Of course it is. I'm making it happy to everyone." said Jack.

"Well, it better be kid-friendly. I don't wants those poor kids screaming and crying about their toys being scary." Rarity warned.

...

The ghouls and the mane six help out Jack getting ready for Christmas by making presents in a scary way, creating skeleton like reindeer, the wrapping are covering in Halloween colors, and so many Halloween themed stuff being Christmas.

While Twilight and Pinkie are helping Jack with something, three kids named Lock, Shock, and Barrel came to the room. "Lock, Shock, Barrel. How lovely to see you all." said Jack. "You called, Jack?" Lock asked. "We're here for you, Jack." Shock said. "What do you need form us, Jack?" Barrel asked as he licked his lollipop. Pinkie thinks they are creepy.

"Well, I would like you to find Sandy Claws and bring him to me." said Jack. "Jack, isn't that kidnapping?" Twilight asked. "Of course not. I Just want to talk to him for something." Jack explained. This made Twilight suspicious about Jack's plan. Whatever it is, it's not good.

The three kids just left to kidnap Sandy Claws and they continued to do what they're doing.

...

Meanwhile, Fluttershy is decorating some candy canes to the present and doesn't know that Sally is watching her.

She went to her and quickly tapped her shoulder. "Can I help you, miss?" Fluttershy as she turned around to see who tapped her. "Sorry to disturb you. Um, can I ask you something? It's about Jack." Sally explained. "Um, sure." said Fluttershy as she follows her to a wall.

"So, what do you want to ask me?" Fluttershy. "Do you think it's wrong for Jack to take over someone else's holiday? Halloween is our main holiday, not Christmas." Sally asked. "I understand what you mean, but he doesn't know its wrong. What's your name?" Fluttershy explained. "I'm Sally." Sally introduced. "My name is Fluttershy." Fluttershy introduced.

"So, do you share my opinion about what Jack is doing?" Sally asked. "You don't like it that he's bringing Christmas here?" Fluttershy asked. Sally shook her head no. "Oh my. I totally agree with you." said Fluttershy. "Then, we have to do something about this." said Sally. "But, what?" Fluttershy asked.

So, Fluttershy and Sally plan to stop Jack from bringing Christmas to the world. Otherwise, he'll be in big trouble. Trust me.

...

When the mane six are still getting ready for Christmas, Lock, Shock, and Barrel has a huge bag for Jack.

They opened it and it's revealed to be Santa Claus. Or in this case Sandy Claws. "Hold on. Is that?" Applejack asked. "Sandy Claws. Am I glad to see you." said Jack, dressed up as Santa. "What is the meaning of this?" Santa asked.

"So, that must be Sandy Claws." said Twilight. "But, what's he doing here in Halloweentown?" Rainbow Dash asked. "I heard that Jack ordered Lock, Shock and Barrel to kidnap Sandy Claws. That's why he's here." Pinkie explained. "What? Why would Jack do such a thing?" Rarity asked.

Twilight went up to Jack and asked angrily, "Jack, what is going on? And what are you doing to Sandy Claws?" "My name is not Sandy Claws. It's Santa Claus." Santa corrected her. "What are you doing, pony? Get out of the way!" a werewolf shouted as he throws Twilight into the crowd.

"You okay, sugar cube?" Applejack asked as she helps her up. "I don't understand. I thought he's going to do this the other way. I have a feeling Christmas is going to be Halloween themed, which is not good." said Rainbow Dash. "What are we gonna do?" Pinkie asked in worry.

Fluttershy went up to her friends with Sally and said, "Girls, I have an idea." "What is it, Fluttershy?" Twilight asked. "This is Sally, a really good friend of Jack and she just told me that she shares the same opinion about Jack's decision." Fluttershy explained. "You two don't like it that he's taking over Christmas?" Rainbow Dash asked. They both nodded yes. "Well, we feel the same way. Not at first, but changed our minds when he kidnapped Santa Claus." said Twilight.

They watch as Santa is being taken away from Halloweentown.

...

That night, Jack is getting ready to take off to deliver presents to children while the mane six and Sally are planning to stop him.

"Okay, I think fog juice will do the trick. That way, he won't see a thing." said Sally as she shows the girls fog juice. "That's really cool. Where'd you get that?" Rainbow Dash asked. "From the science lab." Sally answered. "Cool." Twilight said.

They sneaked behind the well and sees Jack making a speech. "I'll distract him. You pour th fog juice into that well." said Twilight as she flies towards Jack and lands in front of him.

"Why, hello Twilight. You've come to see me fly off?" Jack asked. "You bet I am. I just have to stare at you, that's all." said Twilight.

While she distracts him, her friends gave her the signal, meaning they're ready for the plan to be set. Applejack saw her waving at them and whispers to her friends, "Ok, she's said we're ready. Pour the fog juice." Sally immediately poured the fog juice into the water, causing it to make fog all over the place. Now, they can't see a thing because of it. "You sure this plan will work, Sally?" Fluttershy asked. "Don't worry. It will. Jack will give up on Christmas for the sake of everyone." said Sally.

The fog made Jack in shock and in disappointment. "Oh no. Where did all of this fog come from? I can't see a thing if fog is in the way." he said. "What are we gonna do? Jack, I have a feeling we should cancel Christmas." said Twilight. Jack sighed and said, "You're right, Twilight. We should cancel Christmas. Sorry, everyone." said Jack.

They hear Jack saying he's canceling Christmas, they silently cheered and Sally sighed in relief. The plan was working until Twilight's horn begins to glow unexpectedly "What's this? Is your horn glowing?" Jack asked. Twilight gasped at this and said, "It's not what you think." "Uh oh spaghettios!" Pinkie shouted. "I have a feeling Jack has a plan B." said Rainbow Dash.

This gave Jack an idea. "Twilight Sparkle with your horn so bright, won't you guide my sleigh tonight?" he asked. Twilight was shaking in nervous as she does not want to do this, but doesn't know how to say it by not hurting his feelings. "Please?" Jack pleaded. "Um, Jack listen." Twilight began before Fluttershy went in front of her. "Well, she'll be delighted to guide the sleigh, Jack. I would like to come with you as a personal guidance by telling you where to go." she said.

Twilight grabbed her and whispered, "Fluttershy, what are you doing? We can't just let him scare people on a cheerful holiday." "I won't. He'll learn about it when he doesn't it, then he knows it's wrong." Fluttershy whispered back. "Ok. Let's hope this works." said Twilight.

"So, what do you say?" Jack asked. "I accept your request, Jack!" Twilight answered. The audience cheered for her, except for her friends and Sally. They were concerned about what's gonna happen to them.

Twilight and Fluttershy went onto the sleigh. Twilight was in front because of her glowing horn. "Ready, girls?" Jack asked. "Ready." both Twilight and Fluttershy said. "Alright. Wish me luck! Merry Christmas to all!" said Jack as he flies off to deliver presents to children.

Lets hope Fluttrshy's plan works.

...

While in the human world, Twilight and Fluttershy watch Jack delivering presents to children which scares them and their parents.

He gave one kid a severed head, a Jack-in-the-box that comes to life and chases one, a giant snake eats a Christmas tree in front of a child, a wreath like monster attacks an old lady, and scary looking toys chase after children. This scares them so much that the parents call the police and secures their houses. The military gets involved and searches for Jack so they can shoot him down.

"Jack, do you think this is a good idea?" Fluttershy asked. "How many times do we go through this? Yes. It is a good idea and I'm not changing my mind." said Jack as he looks at the naughty and nice list.

Suddenly, missiles were aiming at them. "Oh my gosh! I knew this would happen." said Twilight. "You said it, they're celebrating by thanking us." said Jack. "Um, I don't think they're celebrating us. They want to kill us!" Fluttershy shouted. "Don't be silly, Fluttershy." said Jack as he realizes the missles are aiming at them. "You're right! Hold on tight!"

But, it was too late. A missile shot them and destroyed the sleigh. "MERRY CHRISTMAS TO ALL AND TO ALL A GOODNIGHT!" Jack yelled as he, Twilight, and Fluttershy fall from the sky. The girls were screaming as they fell.

They landed in a graveyard not too far. "Oh my Celestia, I've never thought we landed that hard." said Twilight. "Oh, my head." said Fluttershy as she rubs her head. "Are you okay, Fluttershy?" Twilight asked. "I'm okay. Wait, where's Jack?" Fluttershy asked in worrisome.

Jack was hanging on an angel statute with his Snata outfit ruined. The girls found him and Twilight asked, "Jack, are you okay?" "What have I done? What have I done? I've ruined Christmas for everyone." said Jack. "Well, you did. We tried to warn you, but you wouldn't listen. This is not who you are, that's why. That's even why me and Fluttershy voulenteered to join you on your quest. To teach you a lesson." Twilight explained.

"I guess I leanred it very well. I'm so sorry for not listening to you. Not even Sally. I must've broken her heart." said Jack. "No, you didn't. She just wants you to do wha you're good at. It's for the best for everyone. You're not Santa Claws, you're Jack the Pumkin King. And it's wrong to take over someone else's holiday." Fluttershy explained. This made Jack feel better by her words and immediately jumped into action. "You're right. You're right all along. I am Jack the Pumpin King! Now, let's go back to Halloweentown and set things right." he said.

"Thats the spirit, Jack." said Twilight.

...

Back in Halloweentown, the girls and Sally are planning to rescue Santa from Oogie Boogie who was out there by Lock, Shock, and Barrel.

"Are you sure this where Santa is?" Pinkie asked. "Yep. This is it. Those brats were right." Rainbow Dash said. "This must be where Oogie Boogie lives. I hope he hasn't killed Santa yet." said Applejack.

They sneaked inside and sees Oogie Boogie messing with Santa. "Come on, Santa. Let's play." he said as he rolls his dice somewhere in his room. "We need to distract him. But how?" said Rainbow Dash. "I have an idea. It just might work." said Rarity.

Her plan was to act like she's flirti with him. "Woo hoo! Oh, Oogie Boogie. Come over here so I can kiss you." said Rarity. "Why, hello gorgeous." Oogie said as he went to Rarity.

The rest were saving Santa from his trap. "Don't worry. We'lol get you out of here." Sally whispered. Applejack unties his ropes and helps him up. "Thank you." he said. "Don't thank us yet. We have to get you back to Christmastown." said Rainbow Dash.

As they were about to escape, Oogie was too busy paying attention to Rarity. "My my, you look beautiful tonight." he said. "Well, I guess you deserve this then." said Rarity as she slaps him in the face and runs off. Oogie rubs his check as he sees the girls and Santa escaping.

"YOU WILL NEVER ESCPAE FROM ME!" Oogie yelled.

...

Jack, Twilight, and Fluttershy run as fast as they can to get to Oogie's lair and save Santa. But, they didn't know that Oogie has captured the girls and Sally.

"There it is! We're almost there!" Jack yelled as he opens the door to the lair and went downstairs. "Jack, wait up!" Twilight yelled.

They saw their friends tied up and was about to be killed. "Oogie, you won't get away with this!" Rainbiw Dash shouted. "Too bad. Because you're about to fall to your doom." Oogie laughed as he pulled down the lever and everyone fell. Twilight immediately uses her magic to lift them and puts them to safety. "Twilight!" Pinkie yelled.

"What? How is this possible?" Oogie asked in anger. "Surprise!" Jack yelled. "What? Jack? I thought you were dead! No matter! Prepare to face your doom!" Oogie shouted as he sets traps to catch Jack and succeeded. "Let me go, Oogie!" Jack shouted. Oogie laughed evilly and said, "Not a chance. You will never get out of here!" He also trapped Twilight by getting caught by robotic nutcrackers.

The only person whose free is Fluttershy, who is scared of what's going on. "What's the matter, pony? Afraid?" Oogie asked. Fluttershy covered her eyes so she won't see the fear. "You should be. Just wait till I kill your friends." Oogie laughed.

His words make Fluttershy angry. We went towards him and yelled, "How dare you! How dare you treat my friends so shamefully!" She noticed a string on him and pulls it. When she did, Oogie's skin was clean off and has bugs that are coming out of him. "No! Look what you have done! My bugs! My bugs! My bugs!" Oogie shouted as he loses more of his bugs until he becomes nothing. The only bug that survived is the mind bug until Fluttershy squishes it with her hoof.

"Alright!" Pinkie shouted. "Way to go, Fluttershy!" Twilight yelled. "I've never seen you that brave before." said Applejack. Fluttershy went to them and sets everyone free. "Well, I better get going. And you better make sure you don't take over somebody else's holiday without permission." said Santa as he flies off.

"Dont worry. He leanred his lesson." said Fluttershy. "I would like to thank you girls for helping do what's right. And thank you, Sally." said Jack. "You're welcome, Jack. We better get going as well. We have other adventures to get to." said Twilight. "You're leaving? Ok, we won't forget you." said Sally.

"Bye, Jack! Bye, Sally!" the girls shouted as they disappeared. "Bye, girls." Jack and Sally said.

...

When they got home from the Book of Disney, they got off the ground and dusted themselves.

"Fluttershy, I've never been so proud of you that much. How does that make you feel?" Twilight asked. "It fells wonderful. It kinda makes me feel like I'm not scared of Nightmare Night anymore." said Fluttershy. "Alright! Let's go to the festival!" Rainbow Dash shouted.

So, the girls went off to celebrate Nightmare Night.

...

When they got back home, Fluttershy went to the Disney Journal and begins to write. She wrote,

"What I learned today is doing what's right. It's wrong to take over someone else's holiday without permission or at all. It's because it's not you. You must do what you're good at. Plus, I'm also getting rid of my fear of Nightmare Night or Halloween."
