Up in their bedroom, the chipmunks were fixing up their costumes for the Halloween party at school they were going to. Simon adjusted his foam rubber suit, as he continuously checked with his mirror for refence, he had constructed a life-size costume replica of a microscopic baterium, which he read to be the most deadly bacterium to the human race, and figured it was the scariest costume he could make.
"Well, I'm all ready," Simon said, "how about you boys?"
"I'm almost done..." Theodore called, from inside the closet.
"You might want to hurry Theodore, we're supposed to meet the girls at the end of the street in about nine minutes and twenty-seven seconds."
Theodore exited the closet. "Okay, I'm ready."
Simon studied Theodore's costume with a curious eye. "So... you're going to the party dressed as a burglar?"
"Not just any burglar," Theodore said, "the Hamburglar!"
Simon revealed a half smile, "Cute idea Theodore, but I doubt anybody is going to know who you are, the Hamburglar hasn't been used as a advertising mascot in years."
Theodore shrugged it off, "Maybe they'll let me get away with swiping some extra candy... oh, I hope they have those little bite sized Snickers again this year, I love those things!"
"Alvin, what's keeping you?" Simon called out into the hallway.
"I'm having trouble with my hair!" Alvin called back from the bathroom.
"What are you dressing as? Cousin Itt?" Simon asked.
"Haha, very funny," Alvin remarked, "no, I'm dressing as the most awesome, and coolest person on the face of this planet!"
"Alvin, you're not going as yourself again this year, are you?" Theodore asked.
"I should rephrase what I said and say I'm dressing as the most awesome, and coolest person on the face of this planet, according to the general public." Alvin said.
"We're running out of time, Alvin," Simon said, "we need to meet the girls at the end of the street in another eight minutes and nineteen seconds!"
Alvin walked back into the bedroom.
"We won't be late on my watch!" Alvin said, as he flipped his wig.
"Oh my..." Theodore said, amused by Alvin's getup.
"Let me guess..." Simon said, "... Justin Bieber?"
Alvin nodded, "If this doesn't win the costume contest this year, I don't know what will!"
"Well, we better get going..." Simon said.
"I can't wait to see what the girls will be dressed as..." Theodore said.
At the chipettes' house, both Eleanor and Jeanette had finished dressing into their costumes.
"I kind of wish Simon would dress up as Edward..." Jeanette said, as she finished dressed up as Bella, "it would've been so much fun."
"I don't believe Simon is into the Twilight Saga like you are, Jeanette..." Eleanor said, as she finished dressing as She-Ra, for nostalgia.
"What's taking Brittany so long?" Jeanette asked.
"You have to ask?" Eleanor asked.
"You guys ready to see the greatest costume of all time?" Brittany called out from the closet.
"Let's see, Britt..." Eleanor said.
Out of the closet, Brittany sauntered, in quite an outlandish ensemble and colored hair.
"Looking hot, Britt..." Eleanor said, jokingly.
"Hey, I'm the most popular artist as far as the public is concerned... I'm Katy Perry!" Brittany said.
"Suits you very well." Jeanette said.
"This better win the costume contest this year!" Brittany said.
Moments later, the chipmunks and chipettes met at the end of the street, but both Alvin and Brittany were upset at seeing each other's costumes.
"Are you kidding me?" Brittany asked.
"You can't be serious!" Alvin said.
"Come on Alvin, what are you thinking?" Brittany asked.
"I'm thinking I'm going to win this year's costume contest!" Alvin said.
"Well think again, because I'm going to win this year's costume contest!" Brittany said.
"No way, there's more girls than guys in the school, the Bieb is bound to win the contest!" Alvin said.
"But Katy Perry is much more eye-catching, I'll be more noticable, and more likely to win the contest!" Brittany said.
"I don't believe this," Simon groaned, "a contest to see who's going to win the contest..."
"Can't we just go now?" Theodore asked.
"Oh, not yet, we have to wait for Cydra." Jeanette said.
"Cydra's coming?" Theodore asked.
"I thought Cydra hated Halloween?" Simon asked.
"Apparently, this is all part of Jeanette's reform program." Brittany joked.
"She needs to have some fun," Jeanette said, "I want her to see there's more to Halloween that just a whole bunch of vampire nonsense."
"Well, where is she then?" Alvin asked.
"If she's not here in another minute, I say we go on," Brittany suggested, "I seriously doubt she'll come anyway."
"I'm not holding you guys up, am I?" Cydra called out.
The group turned around, but was surprised to see Cydra's chose of dressup, as she looked almost exactly like she did when they first met her.
"Um... nice... uh... nice, costume?" Jeanette said.
Cydra rolled her shoulders. "It was the only thing I could think to dress as..."
The others remained silent.
"Well, at least one can say you have the most accurate costume at the party..." Simon said.
"Can we go now?" Brittany whined.
"Yes, let's go..." Simon said.
Later in the evening, the school gymnasium was packed with students, dressed in an assortment of different costumes, from traditional Halloween fixtures like monsters, goblins, witches, wizards, to popular characters from favorite cartoons, movies, anime, manga, and others. Both Alvin and Brittany were relishing in the attention they were drawing because of their costumes, alot of girls at the party loved Alvin's Justin Bieber costume, meanwhile alot of boys got a kick out of Brittany's Katy Perry costume. Elsewhere in the party, Theodore was having his turn at apple bobbing, and after several grueling minutes, finally had an apple in his mouth. Freeing his hands, he pocketed his token, and turned to his brother.
"Your turn, Simon!" Theodore said.
"I think I will pass, Theodore." Simon said.
"Oh, come on, it's fun!" Theodore said.
"Theodore," Simon began, "do you realize the parasites and bacteria that's probably contaminating that tub of water? And you want me to stick my mouth into that pit of filth?"
"But, Simon," Theodore respond, "you are a bacteria... remember?"
"Bacterium," Simon corrected him, "and... oh, never mind..."
Elsewhere in the gymnasium, Jeanette and Eleanor stared on in awe at how Cydra was pigging out on all the candy she could get her hands on.
"You must really like candy, Cydra..." Jeanette said.
"Mmm," Cydra mumbled with her mouth full, "I find sugar very addictive..."
"Can't argue there." Eleanor said.
"There's just going to be one problem..." Cydra said.
"What's that?" Jeanette asked.
"I'm going to have one massive headache in the morning..." Cydra said, "but oh well, it'll be worth it! Where's the apple cidar? I'm thirsty!"
"Over there..." Eleanor pointed out.
"Great..." Cydra walked off.
"Well, she seems to be having a fairly good time..." Jeanette said.
"Yeah," Eleanor chuckled, "I've lost count how many pumpkin cookies she's eaten."
At that moment, the judges of the costume contest walked over, they were dressed as Sheldon and Leonard, and were looking over their clipboards before they approached Jeanette and Eleanor.
"Either of you entered in the costume contest?" 'Sheldon' asked.
"I'm not." Jeanette said.
"Me either." Eleanor said.
"You want to enter?" 'Leonard' asked, "the contest will be starting pretty soon."
"I don't think I'll enter this year." Jeanette said.
"Why bother?" Eleanor joked. "'Justin Bieber' or 'Katy Perry' are bound to win anyway."
"Very well." 'Sheldon' said, as he walked away.
"The bazinga's lost on you." 'Leonard' said, also walking away.
Cydra was fixing herself another cup of apple cidar, when 'Sheldon' and 'Leonard' approached her.
"Would you be interested in entering the costume contest?" 'Sheldon' asked.
"Who me?" Cydra asked.
"Yeah you," 'Leonard said, "you really should join, your costume is highly impressive."
"Oh, this isn't a costume really," Cydra said, partly lying, "just something I threw together..."
"Creativity is the key," 'Sheldon' said, "you're very original, what do you say?"
"Well..." Cydra hesistated.
"Come on..." 'Leonard' said, as he and 'Sheldon' took her by the hand, and drug her away.
Unfortunately, a party wouldn't be a party without uninvited crashers, and two people showed up uninvited, intending to crash the party, slipping past the school security guards by blending in with the crowd, though they weren't wearing costumes either, they just happened to always look like they live in the Hot Topic at the mall.
"This party's kinda on the lame side, eh?" One of the crashers said to the other.
"No shit," the other said, "a little crashing really should liven things up abit."
"When do you want to strike?"
"Very, very shortly..."
Applause filled the gymnasium, as the costume contest went on, the level of the applause was to judge each entrant's costumes, and 'Leonard' monitored the applause meter.
"Next, we have Alvin," 'Sheldon announced, "and baby, baby, baby, check out him pulling off 'The Bieb'!"
Alvin was met with not only applause, but cheers and whistles, as he kept flipping his Bieber wig, 'Leonard' was surprised at how high the meter read the response, never before had it reached levels like this, but was soon to see this again when the next entrant was announced.
"Next is a real firework," 'Sheldon remarked', "let's hear it for Brittany, as she channels Katy Perry!"
Again, loud applause and cheers filled the gymnasium, it was looking like Alvin and Brittany were going to tie. In the crowd, Simon, Theodore, Jeanette, and Eleanor caught up with each other.
"Well, looks like we'll have another monthlong feud to put up with..." Simon said.
"Yeah, whoever wins, the other's not going to let it go for a looooong time..." Eleanor said.
"I kind of wish neither of them will win," Jeanette said, "that way, none of us will have to put up with a sore loser, or a sore winner."
"And finally," 'Sheldon' continued, "our last entrant has royalty as her charm, as we proudly present Cydra, the Vampire Princess!"
The chipmunks and chipettes were shocked beyond belief when they realized Cydra was in the costume contest. Not knowing what to make of what just happened, Simon, Theodore, Jeanette, and Eleanor mustered up the most enthusiastic applause and cheers that they could, which prompted others in the crowd to do the same... even one of the crashers brought up his hands in applause.
"What are you applauding for?" The other asked.
"Let's just say..." the crasher began, "she... intrigues me..."
'Leonard' read the meter carefully, the applause level was just barely above the levels for both Alvin and Brittany, both of whom stood among the other entrants, with their mouths hanging open.
"What does she think she's doing?" Brittany asked Alvin.
"Beats me, she's not even really wearing a costume!" Alvin said.
"That's right!" Brittany said. "She should be disqualified!"
'Leonard' handed 'Sheldon' the readings, as he looked over the scores. "Friends, it would seem the creativity and originality has won out this year..."
Both Alvin and Brittany smirked, while in the crowd, the rest of their group, kept exchanging looks with each other, unsure what was about to happen next.
"So let's have another round of applause for this year's winner," 'Sheldon' continued, "Cydra the Vampire Princess!"
All but Alvin and Brittany cheered for Cydra, who was completely surprised that she won the contest, so much, that 'Leonard' had to drag her to the front of the makeshift stage.
"I can't believe Cydra won!" Simon said.
"I know, this is shocking!" Jeanette said.
"I wonder what made her decide to enter the costume contest?" Eleanor asked.
The applause got to Cydra, as 'Sheldon' handed her the microphone.
"Gee, thanks..." Cydra said to the crowd, "um... at this time... I would like to thank the acadamy..."
This got a laugh from the crowd.
"And I would also like to thank the cast of 'The Big Bang Theory' for insisting I enter this contest." Cydra added, getting another laugh from the crowd, and especially from 'Sheldon' and 'Leonard'. "So, what do I win?"
"Right, we present you with this year's grand prize..." 'Sheldon' announced, while 'Leonard' struggled to carry onto the stage a plastic treasure chest, "incredible riches!"
Cydra opened the treasure chest, and was surprised at all the golden coins that filled it.
"Incredible riches, indeed!" Cydra squealed. "Where did you find all of this loot?"
More laughs were audible, before 'Leonard' took one of the coins, and unwrapped it revealing the golden coins were actually chocolate coins in golden wrappers.
"Hey, even better!" Cydra squealed.
"Some people have all the luck." Theodore said.
"Chin up, Theodore," Simon said, "perhaps she'll let you exploit her wealth."
"Huh?" Theodore responded.
Applause continued, back with the crashers, the main crasher motioned for his partner to follow him out the exit, once outside, they relayed a plan.
"You want to do what?" The partner asked.
"You heard me," the main crasher said, "we're taking her."
"What for?" The partner asked. "You dig her or something?"
"I did..." the main crasher said.
Back inside the party, Alvin and Brittany stormed over to their siblings.
"Alright, where's Cyd?" Brittany demanded to know.
"Why?" Eleanor asked.
"We got a bone to pick with her!" Alvin said
"Why, because she basically stole the grand prize away from you two?" Simon asked, jokingly.
"Hey, she wasn't even legally wearing a costume!" Brittany insisted.
"Yeah, she won that prize unfair and unsquare!" Alvin said.
"Who said she wasn't wearing a costume?" Eleanor asked.
"Right, you heard what they said," Jeanette said, "she won for creativity and originality."
"Creativity and originality my ass!" Alvin said.
"She said so herself, she couldn't think of anything to dress as, which is why she wore that old vampire getup of her's!" Brittany said.
"Well, so much for not having to put up with sore losers." Simon said.
"Look, what difference does it make that Cydra won the contest?" Jeanette asked. "At least got her to let her hair down and have a good time, we may just as well have broken her from her hatred for Halloween."
"I think she deserves congratulations!" Eleanor said.
"Let's go find her." Theodore said.
Cydra was, at that moment, stepping out the exit, looking for a place to bury her treasure, until she and her friends are ready to leave, so she won't have to carry it around for the rest of the party. All of those chocolate coins were rather heavy. She figured she would hide it behind the gymnasium, close to where the dumpsters were, so she dropped it on the ground, and covered it with a large, empty cardboard box, but before she could walk back into the building, a strange feeling came over her, a sudden chill, and a sudden drain of energy, that caused her to collapse to the ground in a daze. Afterwards, the crashers shot out from behind the dumpster.
"Now what?" The partner asked.
"Grab one of those bags, and let's go..." the main crasher instructed.
Cydra's near lifeless body was placed in a large, black trashbag, and the two crashers darted out into the night with her. Back inside the gymnasium, the chipmunks and chipettes met up with each other again.
"We can't find Cydra anywhere." Jeanette said.
"You don't think she already went home, do you?" Eleanor asked.
"This is probably the most excitment she's had in her life," Simon said, "it may have been too much for her to handle."
"Well then, let's get out of here ourselves!" Brittany said. "I'm in a bad mood now!"
"So what else is new?" Eleanor asked.
