The days rolled by rather slowly for Red and Purple.
They didn't really fit the bill to pose as skool kids like Zim did, so they lounged at home while he went to skool.
One day, Zim came home looking very happy. Most unusual.
"What are you so happy about?" Red asked sleepily as Zim threw his skool books on the table in the kitchen.
"A special Earth holiday is tonight." Zim replied, getting something out of the fridge and stuffing it into his mouth.
"Is that something to be happy about?" Purple asked from his place on the sofa.
"It is! Because tonight is the one night in the year where we can walk the streets without our disguises and not be discovered!" Zim laughed, tearing the wig and contacts off his face.
"How come?" Red asked, taking a muffin off the tray next to him.
"This holiday involves human children dressed up as all kinds of non human-things and wandering around getting snacks from the houses. We can go out and people will think we're in costumes!"
"Free snacks!" Red and Purple cried, jumping up and doing a very undignified dance in the living room.
Later that night, Zim, Red and Purple wandered the streets together, in the midst of dozens of young human children.
Zim was given the task of going to the houses to retrieve the free snacks and bringing them back. He didn't seem to mind.
They were only out for an hour or so, and they already had more sugary snacks than they could carry. They had even gone back to the base to drop off a load before returning to the streets to get more.
They were on their third run when something very bizarre happened.
While all the young humans were prowling the streets, a progression of tall, frightening creatures came parading down the streets, with an eerie music coming from somewhere unknown, and most of the creatures singing very creepily.
They took up the most frightening positions and threw pumpkins around while they sang their song, scaring the young children half to death.
As the end of the progression came into sight, Red, Purple and Zim (Who was hiding behind the two taller Irken) saw a team of creatures pulling a straw horse on wheels along behind them, which had a scarecrow with a jack-o-lantern for a head sitting upon it, while the creatures who were at the front of the progression had circled around the young children, keeping them cornered.
They all sang as the horse drew closer.
"This is Halloween! This is Halloween! Halloween! Halloween! Halloween! Halloween! In this town, don't we love it now! Everyone's waiting for the next surprise! Skeleton Jack might catch you in the back and scream like a banshee make you jump out of your skin!"
The pumpkin-headed scarecrow jumped up and burst into flames. It swung its lanky body around, throwing the flames close to the young trick-or-treaters.
The other creatures continued to sing.
"This is Halloween! Everybody scream! Please make way for a very special guy! Our man Jack is King of the Pumpkin Patch! Everyone hail to the Pumpkin King! Now! This is Halloween! This is Halloween! Halloween! Halloween! Halloween! Halloween!"
The creatures burst into laughter and celebrative singing as all the young humans screamed, dropped their trick-or-treating spoils and bolted.
The Irken trio looked on curiously, as the burning scarecrow extinguished itself with a wave of its hands and pulled its head from its shoulders.
As it turned out, all the creatures in the progression were humans in costumes. Red and Purple's eyes widened as they saw whom it was under the pumpkin.
"Isn't that the dance girl?" Purple whispered.
Red nodded. It was definitely her.
The trio were the only ones left in the street after the progression had swept through, so they stood out a fair bit.
While most of the teenage humans collected the snacks that the younger ones had dropped, Chasidy and the boys who were with her on the day Red, Purple and Zim had met her noticed them still standing on the sidewalk.
Chasidy smiled and walked over with her group of boys behind her.
"Hiya!" She said happily. "Enjoy the show?"
"It was different, that's for sure." Purple said, shrugging.
"Don't you have the 'Trickers Take Treats' parade where you're from?" One of the boys asked.
Red shook his head.
"How sad."
"Nice costumes by the way." Chasidy said grinning. "They look as real as ours do!"
"Heh. Funny that." Purple said sheepishly, putting one of his hands behind his head.
Red flinched slightly as Zim poked him.
"We should go." He hissed.
Red rolled his eyes and sighed. He turned to Chasidy.
"We'd better go home now." He said, turning in the direction of the base.
"Aw, do you have to? We could use some more people to help us hit the next suburb. You'll get a share!" Chasidy said pleadingly.
"Uh, thanks, but we've got plenty." Purple started leading Zim away. "Bye."
Red watched Purple and Zim as they stared to walk away and smiled. He glanced back at Chasidy.
"It was nice seeing you again Chasidy." He said, ignoring the confused looks that he was getting from the humans.
He started to follow Purple and Zim when someone grabbed his wrist. He spun around to see Chasidy holding onto him.
"How do you know me?" She whispered. She didn't recognise him without his disguise.
"Red, remember?"
Her eyes went very round. "Oh! Yeah! I didn't recognise you!"
Obviously.
"I didn't know you lived in this suburb! Which house is yours?" She squealed.
Red smiled. He didn't see how it could hurt her knowing where they lived.
"The green and purple house at the end with the giant lawn gnomes in front. You can't miss it."
Chasidy grinned as she let go of Red's wrist.
"Okay! I might swing by some time!"
"Heh. Yeah, you do that."
Red bolted in the direction of the house as fast as he could, passing Zim and Purple along the way.
Red slumped down on the sofa.
"Humans are weird." He mumbled.
"Yeah." Purple agreed, sitting on the floor and leaning against the giant pile of sugary snacks that they had collected and chewing on a chocolate bar. "Pretty impressive show though." He said thoughtfully.
"I suppose…"
Zim yawned as he walked through the living room. He paused at the door to the kitchen and looked back.
"Do you two intend to just sit around all day tomorrow?" He asked.
"We don't have anything better to do." Red mumbled, rolling onto his back.
Zim sniffed. "Perhaps you could find something."
Red and Purple looked at Zim strangely.
Zim shrugged it off and turned back towards the kitchen.
"Goodnight." He muttered before disappearing down into the lower base.
A/N: The halloween song is from nightmare before christmas. I liked it so i put it in instead of writing my own. DON'T KILL ME! Oh, and I wrote this chap with total disregard for the halloween ep of Zim, in which Zim hates halloween. So that's why.
