"Well, I think it's nice for the three of you to move out of Oogie's lair" Said Jack Skellington, a six foot nine skeleton that's dressed in a suit and considered the Pumpkin King.

"Yes. Especially wanting to study!" Said Sally Skellington, a ragdoll creation that's six foot two dressed in a red dress and is married for eight years to Jack.

"But what made you hooligans consider such things?" The mayor said switching his face to happy.

"Does it matter" Said Lock, a five foot ten devil wearing a dark red jacket, red shirt, dark red jeans, and maroon shoes.

"Yeah. At least we considered it" Said Shock, a five foot five witch wearing a purple vest, lilac strapless dress, violet witch hat and boots.

"Let alone actually do it" Said Barrel, a five foot nine ghoul wearing a skeleton print shirt and pants and black sneakers to hide his deformed feet.

At the town's municipal hall, the three finest trick-or-treaters had called for the Skellington couple and the mayor. Now no ordinary citizen of Halloween Town could have done this; calling for important people at such short notice but Jack deemed them 'special' citizens. This is because he had seen the whole incident wherein the three of them saved the whole town.

"Okay. Okay. We won't question your decision anymore." Sally stated to stop the impending argument.

"So, where do you want to move to?" Jack asked as the mayor looked stupefied by the flow of conversation and mood.

"In the Hinterlands" Lock said.

"Yup" Barrel seconded the decision.

"And we want to build it ourselves" Shock stated.

"Alright and while you do that, we'll enroll you to Spooky High" Sally said smilling her ragdoll face.

"Wow" Sally said as she looked at the three's new abode.

"Holy Pumpkin!" The mayor exclaimed as he laid eyes on the new home.

"Well done children! This is an exceptional feat for the three of you" Jack said as he clasped his hands together.

It was true, their new house was stunning. In just a week, they had built their humble abode in the Hinterlands. Shock had used magic to do most of the building while Lock and Barrel; with the help of Shock's potion did manual labor. The house looked more like a Victorian castle than a shack. It had a bricked fence surrounding it with a creepy black pointy gate. The tower walls were covered with vines while the others just showed plain grey bricks. It had stained glass windows and black doors. The roof was a dark shaded bricks that was formed into cones.

"Thank you very much" Shock said curtsying as she smiled. She was clad in a violet shirt, dark violet jeans, and purple witch hat and boots.

"It's the only thing we had worked on that's not a prank" Barrel beamed and jumped up and down. He was dressed in a black shirt, jeans, and shoes.

"All we need now is furniture" Lock stated and posed unwillingly. He wore a dark red shirt, jeans, and sneakers.

"Don't worry; we will help you with that. Right mayor?" Sally said threatening the mayor a little.

"Uhm. Yes-yes" The mayor stuttered.

"Alright but for the meantime, you three go to school" Jack said as he threw three bags to the hooligans.

"What are these?" Barrel asked as he inserted his hand into the bag.

"Hmn. Notebooks, some stationeries and-" Lock stated as he himself rummaged through his bag.

"What the F*ck! Is this a uniform?!" Shock said. She felt a soft fabric as she rummaged through the bag like her cohorts and pulled it out. She saw a white dress with a patch of Spooky High at the left side.

"Yes it is, a student is required to wear it in school premises and activities at all times" The mayor stated and he saw Shock's blood lustful eyes land on him.

"Ah-Shock, we do have a washing machine at our house, you know" Sally said and they both disappeared and then reappeared in a moment's notice. By now, she held in her hands a now lilac school uniform.

"Smart" Lock said smirking as he saw the now lilac uniform.

"*sigh* Very well, Go now" Jack said as he saw the whole situation about to escalate. Shock used her magic to change their clothes.

xxxxxAt Spooky Highxxxxx

"Alright class, we have three new students about to come in so I expect everyone to behave" A mummy said as he pointed to the door. "Cassandra open" He said and immediately the door opened revealing three teenagers. One had red slick hair with a single spike on each side, yellow eyes and black irises, pale white skin, and handsome face clad in a white buttoned sleeved shirt with a Spooky High patch, black pants, and black shoes. Another one had green messy hair, blue irises, light blue-green skin, and a cute and scary roundish face also wearing the same as the other one. And finally, in the middle of the two was a girl with powdery light green skin, grey irises, dark purple hair and beautiful/cute face clad in a dress similar to the other girls but color lilac.

"Okay new students, would you like to introduce yourselves" The mummy said as the three came in. The girls swooned over the new boys while the boys wide-eyes at the new girl.

The three of them huddled for a while then turned to face the students. The girl wiggled her finger and the lights went off. Suddenly smoke filled the room which made the students scared and teacher alarmed.

"Monsters of every kind in this little classroom of ours"

"Would you like to see something scary?"

"We are the henchmen of the 'Shadow of the Moon'"

"Even monsters' dreams are filled with fright"

"At the sight of our master"

"But don't be alarmed, he's already dead"

"Killed by Jack and destroyed by us"

"Don't you be frightened"

"We won't bite-much"

"We can't help but be scary too much"

"That's how we were taught by master"

"Hehehe. Says the wicked witch"

"Boo. Says the ghostly ghoul"

"Greeting from down below, HELL-o. Says the deviant devil"

"Now, we would like to present"

"Our little show"

"We apologize for anyone who gets frightened"

"We apologize?"

"NO!"

And suddenly there were red lights. The smoke grew thicker, there was an eerie music being played.

"Once we were trapped"

"But now we're free"

"To terrorize"

"Horrify"

"Halloween even more"

A flash of green appeared and showed Barrel's mask, after that a flash of violet with Shock's mask, and after that a flash of red appeared with Lock's mask.

"Please, welcome"

"Lock" The red haired devil said as he appeared floating.

"Shock" The girl said as he appeared next to the devil.

"Barrel" The green haired ghoul added as he floated next to the girl. Then the three of them disappeared. And Oogie's laugh began to play that cause the students and even the teacher to be frightened.

"Three of a kind"

"Birds of the same feather"

"Now and forever"

And with that Oogie's recorded laugh played even louder. As the smoke revealed three thrones; each decorated differently. And on those thrones were the masks that flashed earlier.

"A devil" In the first throne popped out the red haired boy. "Lock"

"A witch" The middle throne poofed out the lilac uniformed girl. "Shock"

"A ghoul" And at the last throne suddenly appeared the green haired boy. "Barrel"

"Please to make your acquaintances" Lock said as he sat on his throne and wore his mask.

"How quaint it is to see your faces" Shock said as she sat on her throne and wore her mask.

"Nice to meet you all" Barrel said as he sat on his throne and wore his mask.

"Be careful around us, cuz' we might chop something off" The three of them hollered in unison.

By this time, everyone else thought that they were outside. But this was only because Shock made a spell for dramatic effects. And with a snap of the three's fingers one by one, everyone was in their respectful places as if none of the things they saw happened. An eerie silence filled the room since everyone was trying to cope on what they saw. Lock, Shock, and Barrel just grinned.

"So, Lock, Shock, and Barrel" The mummy teacher said pointing to which the person of the name was.

"Yup" Barrel said beaming, his face no longer serious like earlier.

"Yes" Shock said sweetly contrary to her facial expression which was deceitful.

"Yeah" Lock said as he smirked making the confused girl students swoon. They saw three empty seats and sat there.

"Did I tell you to sit there?" The teacher said.

"No-" Barrel said.

"-But really, where-" Shock said.

"-Else would we sit?-" Lock said.

"- It's not-"

"-Like there's-"

"-Other seats-"

"-That-"

"-Are-"

"-Empty." The three of them finished each other's sentence and smirked at the teacher who was dumbfounded.

"DETENTION FOR THE THREE OF YOU!" The mummy yelled.

"What injustice!" Shock exclaimed.

"What's a detention?" Barrel asked to no one in particular.

"They have detentions here?" Lock teased more than asked.

xxxxxxxTIME SKIPxxxxxxxx

"So, hooligans. How was your first-" Jack said as he laid his eyes on the three who looked impish after detention.

"How was our first day, Jack?" Shock said finishing what the skeleton was saying.

"It was fun" Barrel said.

"Especially detention" Lock stated.

"Your three got detention on your first day?" Sally said more than asked. She looked at her husband with his facial expression changing. Three, two, one.

"YOU GOT DETENTION ON YOUR FIRST DAY!" Jack stated in a loud voice.

"Why is that, children?" Sally asked.

"I don't know" Barrel said shrugging his shoulders.

"Maybe it was our little show" Shock said.

"That and the way we treated that mummy" Lock stated confirming their doubts.

"AGAIN. DETENTION ON YOUR FIRST DAY!" Jack yelled. And the trio rolled their eyes at what Jack lectured on and on about proper behavior and blah, blah, blah.
