Pallet stretched in his bed, happy about what today was, his favorite day, Halloween. Where he could go visit the different AUs with his fathers and get candy and other treats from the participating Sanses and Papyruses. (The Undynes, Alphyses, Toriels, and Asgores are too confused about the different AUs, so they rather not participate.) Pallet stretched once more and rolled out of his bed and happily bounded down the hallway to his fathers' room. "Dad! Papa!" He called. "Happy Halloween!" He then heard tired grunting, which was definitely Dream, because Ink was very much a morning person, Dream prefers to sleep practically until 1:00 if Ink lets him. Ink walked over to Dream's side of the bed and clacked his teeth against his skull lightly, (a skeleton version of a kiss.) Then he walked over to the bedroom door and opened it. "Hi Papa!" The smaller skeleton greeted. "Happy Halloween!"

"Happy Halloween to you too!" Ink replied and he picked up Pallet into a hug. "Let's go wake up your Dad."

"Wake up lazybones!" Pallet yelled at Dream. "It's Halloween!"

"Mmph." Dream responded. Pallet jumped out of Ink's arms and jumped on top of Dream.

"WAKE UUUUPPPP!" Pallet screamed louder. But Dream didn't respond that time. Until,

"GGGRAAAAGH!" Dream screamed as he quickly jumped up and scared Pallet.

"AGH! Dad!" Pallet scolded. "You scared me!"

"I know, that was what I planned." Dream replied as he smiled brightly at his son and his boyfriend.

"C'mon, Dream, we promised Death and Geno that we would take Goth and Raven trick or treating with us while they went on a date." Ink said as Dream finally got out of bed. "Here, grab my hands." Ink told Pallet and Dream, when they did, he teleported them to Reapertale, where Geno and Death lived. "Pallet, go knock on their door, please." Ink asked. Pallet walked up to Death and Geno's house and lightly rapped on the door, then Death opened the door.

"Eh? Oh! Hello, Pallet! What do you say?" Death greeted. Death was always in a good mood on Halloween.

"Trick or treat!" Pallet said as he held out a bag for candy. Geno appeared at the door as well and he and Death gave Pallet two chocolate bars and a cinnamon bunny. "Thank you!" Pallet thanked happily.

"Goth! Raven!" Geno called. "Pallet is here!"

"Pallet!" The brothers yelled from within the house. "Pallet! You're here!"

"Yep!" Pallet responded.

"Are you ready to get some candy?" Raven asked.

"And get scared?" Added Goth.

"Yes! Definitely! Dad and Papa are waiting for us outside!"

"Yay!" The brothers yelled again before running to Dream and Ink. Dream and Ink waved at Geno and Death, as they waved back.

"Ready, boys?" Dream asked.

"And remember that we need to stop at our house for your costumes!" Ink added. The three boys just nodded happily at the two older skeletons. They all held onto Ink as he teleported them back to Dreamtale where Dream, Ink and Pallet live.

"I already know who I'm dressing as!" Raven announced as he ran to the bathroom to change into his costume. A moment later he came out with a tiny blue jacket with a fluffy gray hood over a white shirt stained red with ketchup, a pair of black basketball shorts that were a little too big for him and a pair of blue and white sneakers. "I'm Horrortale Sans!" Raven said. Then Pallet and Goth ran into Pallet's room to change into their costumes. Ink had given a black morph suit to Pallet for Halloween, so Pallet slid into the suit, and painted a bright blue circle over where his left eye should be.

"Who are you?" Goth asked.

"I'm my Uncle Nightmare!" Pallet answered, clearly happy with his costume choice. "If you want to, you can borrow something out of my closet."

"Okay, thanks!" The other skeleton responded.

Hmmm. What to wear? He thought to himself. Ah! Maybe I could go as... Underswap Sans! Goth found a blue cloth he could use for the scarf, and he couldn't find a battle body, but he found a gray T-shirt, which was close enough to Blue's battle body. And a pair of dark blue sweats with a pair of blue boots. Dang, Pallet has everything! Probably because Ink can create anything, he probably creates Pallet's clothes! Goth got into his costume and ran down the hallway to the other skeletons. "I'm ready!" He said. Ink was the main mode of transportation, so he took the boys and Dream to the safe AUs, and he would decide later if they should visit the dangerous AUs.

"Papa? Can we go to Underswap first?" Pallet asked.

"Which one? Underswap or TS!Underswap?"

"The original." Pallet answered. "I want to see Blue."

"Sounds good." Ink said as he teleported them to Underswap.

(Ink teleported to the skeleton's house's doorways) Ink knocked on the door and Papyrus answered wearing his signature orange sweater and brown shorts.

"Hello Ink, Dream, kids. Blue's inside if you want to see him, he'll go trick or treating later." Papyrus greeted.

"He's scared of Error!Sans." He added quietly.

"He can come trick or treating with us if that's okay with you." Ink said. "I'll handle Error if it comes down to it."

Papyrus' grin widened as he thanked Ink and calle Sans down to the door.

"Sans, Do you want to go with Ink and Dream?" Papyrus asked.

"YES PLEASE!" Sans answered. "BUT WHAT ABOUT ERROR ME?" He added nervously.

"Don't worry, I'll handle him, I have been handling him for years." Ink answered honestly.

"Yay! Thanks Ink! Thanks Papy!" Sans yelled happily "OH YEAH, AND THANK YOU TOO, DREAM!" Sans went inside and put on his battle body and grabbed a bag for candy and treats. "I'M READY" Then the skeletons went on their way.

"Wait! Pallet!" Papyrus called. "Here, split this between you, Goth, and Raven" he added before handing Pallet a handful of candy.

"Thanks Papyrus!" Pallet thanked before joining his fathers and his friends. They grabbed Ink, then they teleported to Underfell and knocked on the door.

"IMMA COMIN" a gruff voice spoke, then the door opened. "SANS! SWAP YOU, DREAM YOU AND INK YOU ARE HERE WITH SOME KIDS!"

"I'm comin', Boss!" A deeper voice yelled back. Then Sans slid lazily down the stairs. "'Sup"

"SANS! WILL YOU REFRAIN FROM SLIDING DOWN THOSE STAIRS! YOU RISK HURTING YOURSELF!" Papyrus scolded, but quickly added with with blush. "NOT THAT I CARE OR ANYTHING, I, THE TERRIBLE PAPYRUS, HAVE NO FEELINGS!"

"Sure, Boss." Sans answered. "Hiya, I'll go get you kids some candy." Sans announced, then he came back a moment later and gave Pallet, Goth and Raven some candy. "Lemme guess, Pallet, you're Nightmare!Sans, Raven, you are Horrortale!Sans, and Goth, you are Blue." Sans guessed with a toothy grin, flashing his golden capped tooth.

"WAIT, GOTH, YOU ARE ME!" Blue yelled excitedly. (Surprisingly, he hadn't noticed until Edge mentioned it. But Stretch had noticed. He thought that Goth looked adorable dressed as his brother.) "YOU LOOK JUST LIKE I, THE MAGNIFICENT SANS!" Blue was very happy at this.

"BROTHER! HOW DO YOU KNOW THESE KID'S NAMES WITH EASE?" Red asked Edge.

"Uhh. Well, I guess it just comes with time and getting to know them." Edge answered, absently swirling his bright red tongue around his gold tooth.

"Well, we better get going, bye Edge, bye Red!" Dream said.

"Buh bye." Edge drawled.

"FAREWELL!" Red yelled after them.

"That's odd. Usually Red isn't in that much of a good mood." Ink said.

"Maybe because it's Halloween." Dream answered. "What AU do you want to do now?"

"Outertale." Ink answered as he teleported them into the outer space AU. Then Raven knocked on the door.

"SANS! IT SEEMS THAT WE HAVE COMPANY!" Papyrus yelled. "MAKE YOURSELF PRESENTABLE!" He added while opening the door. "HELLO! I HAVE NO IDEA WHO ANY OF YOU ARE, BUT WELCOME!"

"'Sup" Sans greeted lazily. Putting on his orange, yellow and purple jacket.

"Here, have some candy." He added as he gave Pallet, Goth, Raven and Blue some candy to add to their goody bags. Papyrus just swished his blue translucent scarf behind his neck and lifted his brother over his head. Everyone said their goodbyes and held on to Ink again. Without notice, he teleported them to Fellswap.

I guess we're going to the dangerous AUs now. Dream thought to himself.

Once more, they appeared at the doorstep of another Sans and Papyrus. This time, Blue knocked on the door.

"TRICK OR TREAT!" he yelled through the door.

"PET! OPEN THE DOOR AND GREET THE GUESTS." a voice similar to Blue's yelled out, except it was slightly gruff sounding.

"Yes M'lord." A feeble voice answered. "Anything for you M'lord." Then the door opened. On all fours was a skeleton wearing an oversized jacked with a very fluffy hood over his head with one gold tooth.

Like a Papyrus version of Underfell Sans! Raven thought.

"Come in. Make yourselves at home." Papyrus said, while crawling back to his master.

"WELCOME! I AM THE MALEFICIENT SANS! AND I HAVE SOME CANDY TO PRESENT TO YOU!" Sans said as he got up from his couch and put candy in the bags. "BEFORE YOU GO, THERE ARE MORE TO MEET!" He added.

"GRAPE! WE HAVE VISITORS!"

"VISITORS?" another voice screamed back. Then another Sans with a dark purple scarf, a black t-shirt, purple sweats, black boots and a dark gray battle body. He was followed by his brother, Papyrus had a dark pink jacket with a gray-brown hood, a pair of shorts and yellowed bones.

"Ah, Ink, it's good to see you again." The other Papyrus spoke.

"Swapfell. Good to see you again as well." Ink replied.

"Ah, Dream, Blue, Kids, this is Swapfell Papyrus and Swapfell Sans."

"But aren't we in Fellswap?" Raven asked.

"I'm pretty sure he said Swapfell." Goth answered.

"NO." Grape and Raspberry replied at the same time. "WE ARE IN FELLSWAP."

"PAPYRUS AND I ARE JUST VISITING FELLSWAP TO CAUSE CONFUSION."

Swapfell Sans said. Blue noticed that Raspberry looked like a Sans version of Underfell Papyrus. Personality and all. Same with Fellswap Papyrus and Underfell Sans.

"Well, we only have enough time to visit one more AU. What will it be kids and Blue."

"Horrortale!" They all said together.

Ink just sighed, as if he wasn't surprised. And teleported them to Horrortale. This time. Dream knocked on the door. Readying for a fight if it got down to it. Ink doing the same.

"I got it!" Sans yelled. They heard shuffling as Sans got to the door. "Finally! Trick or treaters!" He said happily. A genuine grin on his face.

"TRICK OR TREATERS?!" Papyrus yelled. "WOWIE! WE NEVER GET TRICK OR TREATERS!" he added, sounding happier.

"PAPYRUS, WHAT'S THAT RED STUFF ON YOUR TEETH?" Blue asked. Genuinely concerned for his friend. (Yes, friend.)

"OH THAT'S JUST.... UH...." Papyrus tried to answer.

"Ketchup!" Sans answered for him.

"YES! BLUE, IT'S JUST KETCHUP. I FEEL LIKE SUCH A CLUTZ FOR NOT CLEANING UP AFTER I ATE ONE OF SANS' HOTDOGS!" Papyrus said with a wink to his brother.

"Oh, and here's your candy." Sans said while reaching into the hole in his head and surprisingly, pulled out candy for the kids and Blue. "Happy Halloween." He said as they said their goodbyes.

"So, Blue, Stretch just texted me and said that you can spend the night. And Raven and Goth, I'll call Death and Geno and see if you can spend the night as well." Dream announced.

"YAY!" The kids and Blue yelled together. Dream and Ink just smiled as they teleported back to Dreamtale.

"Y'know, Pallet, I just noticed that you went as your Uncle Nightmare." Dream said with a laugh.
