Blue checked himself in the mirror one last time, double checking the fur was properly glued to his face and the strategically ripped shirt with another shirt sporting more fur under it were both still exactly so. Yup, his Halloween costume was exactly as he pictured it in his mind, and it would definitely be the coolest costume of their group. Not that he didn't have faith his friends could make cool costumes too, he couldn't wait to see what they had come up with, but Blue was going as a werewolf, the coolest fake monster out of all the fake monsters humans had come up with while the real monsters were trapped under a mountain for a thousand years.

"Bro, I'm heading out."

"Okay, Papy! Have fun at your party." Blue popped out of the bathroom and ran to the banister to wave down at Stretch as he closed the door behind him. Blue didn't need to go outside and use their mysterious basement machine to make a portal though, he could make his own. With a wide grin he opened his own pixelated portal to the agreed upon AU and hopped through.

He was the first person to arrive.

Excellent! Cool people were early, fashionable people were late. Blue supposed that meant all his friends would be fashionable.

"Hello, Blue!"

"Hello, Dream!" Blue said as he turned around, having recognized his friend's voice. He looked Dream up and down, gone were his usual clothes and in their place was a long white dress, over which was a swath of yellow-orange fabric, both held in place by a wide leather belt, and on his feet were a pair of strappy sandals. To finish off his costume Dream was holding a plastic pumpkin pail that had been painted a shimmery gold (presumably by someone inexperienced judging by the phalange smudges and obvious drips), a big fake leaf glued to the rim, and "TO THE FAIREST" written in smudged black marker across it. Blue grinned broadly, "You look so good! I love your costume."

"Really?" Dream smiled and twirled quickly to show off the whole thing.

"Yes! You clearly put a lot of thought and work into it, and it looks amazing!"

"Thanks! I love your costume too! Is that real fur?"

"Yes, I told the shop keepers about my costume and asked if they would be willing to donate the fur in their brushes or something and they went a step better! They got their whole pack to do some grooming and kept all the clippings for me."

"That's so sweet of them."

"It really was." Blue would have gushed further, but a dark portal opened and two new monsters stepped through. "Oh, uh… hello Geno, Reaper. What are you doing here?"

"Error invited us to go trick-or-treating with him," Geno replied.

"We've never been before, it sounds fun," Reaper added.

"Well… we didn't know he'd invited you two…" Blue started, unsure where he was even going with this.

"The more the merrier," Dream cut in.

Blue nodded along eagerly, "Yeah! The more the merrier! Having a bigger group will just… wait." Blue squinted at Reaper, "Where's your costume?"

"What're you talking about? This is my costume." Reaper motioned to himself and his usual black robes held together by a pair of ropes tied into nooses. "I'm dressed as the grim reaper."

"Reaper, you are the Grim Reaper," Dream said with some disappointment in his voice.

"The whole point is to dress up as something else! You need to go find a costume right now."

"Told you," Geno said smugly.

"Even Geno's in a costume," Blue added, motioning to Geno. He was clearly wearing a store bought suit jacket/frilly shirt combo with attached cape instead of his usual white hoodie, combined with the usual red dripping from his mouth it was pretty obvious he was supposed to be a vampire. It was a pretty lazy costume, especially with his normal shorts and red stained slippers under it, but it was still more effort that going as himself.

"But I got this prop," Reaper whined while holding up a fake raven with wires sticking out of its feet.

"Go get a real costume or you can go trick-or-treating with us," Dream said emphatically.

Reaper turned his blank, void dark eye sockets on Geno.

"Don't look at me, I wanna go with Error."

"Oh fine, I'll be right back." Reaper disappeared through another swirling black portal.

"F-five G says he-e'll just buy a gr-rim reaper costume," a glitchy voice said.

"Error!" Blue turned to see Error walking up to them. "Error, you don't have a costume either."

Error was wearing his usual clothes, though they looked like he'd just been in a fight, there were a few splatters of paint and some rips here and there. Error shook his head, "This is my c-costume. Loo-oo-ook." He pulled something pink and puffy from his pocket and slipped it onto his head, a black piece of elastic keeping it in place. Now on his head it looked like a crocheted piece of coral with little green tear drops coming from it. "Tada! I-I'm a zombie."

Blue stomped a foot, "The point is to dress up! Not wear your usual clothes!"

Error shrugged, "The ab-bominations won't know-w the difference."

"I'm back. Hey Error, where's your costume?"

"I'm a zo-ombie."

"No fair! How come he gets to wear his normal clothes?"

"They aren't his normal clothes, they're zombified." Geno pointed at one of the paint splotches. "Anyway, what'd you get?"

"I got this!" Reaper took off his ropes, replaced the one at his waist with a purple belt that had a plastic tiny skull for the buckle, and put on a pointy black hat. "Tada! I'm a witch. I can even keep the raven as a familiar, isn't that right?" Reaper cooed to his fake raven.

Dream giggled while Blue sighed, "I suppose it'll do."

"Am I late?" Ink popped out of a puddle, sadly wearing his regular clothes.

"Ink, not you too!" Blue lamented. Everyone else was laughing.

"What? I swear I got the date and time right this time." Ink started scouring his scarf for the note about the night's event.

"You're supposed to be wearing a Halloween costume. I recently found out most humans think we're children because of our height, so we're going to jape them by pretending to be children and going trick-or-treating."

"Oh, right. Okay, gimme a minute!" Ink splat some paint on the ground and jumped through it.

"Error, got any safety pins on you?" Geno asked.

"Sure, but wh-hy?"

"If we're supposed to be kids then Reaps probably shouldn't have a wardrobe malfunction. His robes won't stay closed without something holding the neckline together."

"Awwwww Geno, will you get jealous if I have a nip slip?"

"You don't even have nipples," Geno grumbled, though his face was dusted lightly with color.

"Here, just t-take them." Error handed over the safety pins, then stepped aside to let Geno fuss over Reaper's robes. He moved to stand near Blue, who was feeling pretty let down by his friends but was trying valiantly not to let it show. "I lik-ke your costume."

Blue perked up, "Thank you! I'm a werewolf!"

Before Error could respond Ink popped back into the side alley they'd been gathering in, holding up a roll of toilet paper. "Here it is!"

Error snorted, "Are you supposed t-to be poop? Because yo-our clothes are the col-lor of poop."

"No, I'm going to be a mummy!" Ink said cheerfully. "Help me wrap myself up in this."

With one last sigh Blue gave in and went to help Ink put on his "costume."
