Whoo! :D A TNBC and Super Mario crossover! Oh boy! OwO Once I post the second chapter, I'll move it to the crossover section. :D

I finally managed to come up with a good idea! At least, I hope I did. I just hope that you guys will enjoy it! Yes, there may seem to be some parts that are far-fetched, but do bear with me. It takes place after the movie, after the game Oogie's Revenge, and will also be following the canon of the soundtrack, too.

This story will be relatively short, but I hope you'll like it regardless.

Songs will be featured, either inspired by the renditions of the movie's songs that are in Oogie's Revenge, or one of my own. Oh yes, and both Mario and Luigi will be involved! So don't worry, Luigi isn't left out! :)

Pairings are Jack/Sally and Mario/Peach...with mentions of Luigi/Daisy. :D

The Nightmare Before Christmas-Tim Burton

Super Mario-Nintendo

Today's song is a rendition of In The Dark of the Night from Anastasia. All rights reserved! I don't like the movie, but I love that song! :D It'll be the same title. :)

In The Dark of the Night-Oogie Boogie, LSB, and the buggy creatures.

"I hope you have a good day, Jack." Sally said softly, smiling to her beloved. "I'm sure you'll think of some amazing ideas for next Halloween..."

Jack grinned widely, and gave her a hug, twirling her around a bit. "I'll do my best to prepare something dreadful, dear Sally! And then Thanksgiving! That fantastic holiday about worshiping a dead bird! Oh! Will you be all right today? I may be home a little late."

Sally nodded, and took his hands. "I'll be all right, Jack. I heard from the witches about an interesting set of mushrooms located somewhere in the woods, so I might go out and find them today. But I should be here when you get back. We can...we can sit by the fire and read together, if you want..." She suggested softly. It was one of their favourite little evening past-times.

If there was one thing Jack loved about having Sally living with him, it was definitely her seeing him off in the morning when he was to consult with the Mayor about ideas for next Halloween or any other upcoming Holiday, and coming home to her later on after a tough day's work of planning and throwing out ideas, and any other duties that he needed to fulfil. It really was nice to have someone to come home to, to spend time with and feel better about tough moments during the day.

"Splendid!" Jack grinned some more, just beaming at her. "I'm missing you already, my Sally. I'm looking forward to tonight!" Indeed it was never fun to leave her side during the day, even for just two minutes! There was just such an overwhelming need to be near her all the time, it was almost impossible to bear! Then again, it did give him something to look forward to by the day's end.

In a sweeping gesture he pulled her close yet again and kissed her, lovingly and sweetly.

Sally immediately reciprocated his sweet kiss, and brought her arms around him happily. She came closer to his bony body, eyes closing, just completely lost in the moment. Jack's kisses never failed to bring sweet happiness and joy, as well as reminding her yet again of the reality of them being together in their sweet courtship.

It's been nearly two years, this Christmas... Sally couldn't help but think.

The two parted, and Jack just didn't want to let her go! He almost wanted to just toss aside his duties for the day and just be with her, cuddling her, dancing with her, snuggling, caressing her cheeks, kissing her sweet face...he just wanted to shower her with love! But no, duty called, and he had to take them seriously.

"You have a dreadfully wonderful day, Sally!" Jack let go of her, but held her little hands in his. "I love you, I love you so."

Sally felt like blushing, as she stood up on tiptoe to kiss him sweetly, then pulled back. "I love you too, Jack...you have a dreadful day, too..."

Jack sighed dreamily as he let go of her, placing his hand on the doorknob. "I don't know how I ever won't with you around." He grinned, still in a lovesick manner, and waved at her. "Goodbye, Sally!"

"Goodbye, Jack. See you tonight." Sally clasped her hands at her waist, smiling lovingly.

With one more wave, he opened the door and stepped outside, shutting the door behind him. A bounce in his step, Jack practically skipped down the stairs, headed through the gate and grinned as he saw Clown passing by on his unicycle.

"Good morning, Clown! Another horribly nice day, isn't it!" Jack said happily, waving at him.

"You said it, Jack!" Clown grinned, giving him a newly-learned thumbs-up.

"I knew you'd think so!" Jack continued on his way, and passed by the local band playing a little song, and tossed them a coin, which landed in the smaller player's saxophone.

"Thanks a ton, Bone Daddy." He said, looking at him.

"Anytime, fellas! You keep it up!" Jack said, and practically danced down the street with grace.

The other band members chuckled, shaking their heads. By now they were used to Jack usually being very cheerful in the morning, and by now, everyone knew why.

As Jack headed to the Town Hall, he exhaled and couldn't keep his goofy, lovesick grin off his face. It was hard not to feel cheerful in the morning these days, wasn't it? He supposed that being so in love really must've made him crazy. Not that he complained though, he loved the feeling.

Little did he realize just how much things could change over the course of a single day.

XXX

Rising from within the depths of the Underworld...wherever that may be, was what looked like a green mist. It floated along the graveyard, hauntingly. The ghosts were quite puzzled by this, but there was a strange feeling that emanated from within that strange, green mist that traversed around the tombstones, along the pumpkin patch, going further out toward...

The old treehouse.

It was there that the mist slowly took form, with an evil laugh escaping it, as if it were an undead creature. "Ooh-hoohoohoo..."

Inside, Lock, Shock and Barrel were currently working on a new pranking scheme. Just as always, of course.

"Why don't we turn the town's water that dreadful colour of pink?" Barrel suggested.

"Lame! Besides, we did that last week!" Lock said, kicking aside some papers. "Besides, Jack will just give us grave-digging chores again!"

"Please, Jack has gone soft!" Shock snorted. "Ever since he's been with Sally, he's just all goofy and soft all the time, singing and dancing in the middle of the street!" She made an exaggerated gagging noise. "So why worry? Obviously he's going to be too caught up in finding a new way to smother her with all his mushy feelings!"

"'Oh Sally! How I love you! Oh Sally, be my Valentine! Sally Sally...'" Lock mimicked. "Every word out of his mouth has her name in there somewhere!"

"Maybe we should do something epic! Since he's distracted with her, he won't care." Barrel suggested again, licking another lollipop.

"Hoo hoo hoo! That won't be necessary..." Came a new, but familiar voice.

Chills ran up the spines of the kids, and they huddled in the middle of the room, looking around.

"Did you guys hear that?" Lock gulped.

"I did!" Shock said.

Barrel nodded. "Uh-huh..."

"Either we're all crazy, or that was..."

"Oogie Boogie!" They all said at once.

The strange, eerie, green mist floated into the room through an open window, setting itself in view of the three shivering trick-or-treaters, and then began to take shape. It formulated, grew bigger, took on a large shape, along with dark circles and a gaping mouth. Lock, Shock and Barrel all stared with widened eyes and dropped jaws as the green mist took on the spirit form of none other than the dreadful, horrible, terrible, and completely evil...Oogie Boogie, the dreaded Boogeyman.

"Surprised to see me, kiddies?" Oogie Boogie's spirit form leered at them before laughing. "I knew you would be! It's been a while since I had my fun in running the joint, hasn't it?"

"No...you're gone! Jack defeated you!" Lock tried to sound brave, but even he was quivering like a shaken jitterbug.

"That may be...but my spirit lives on!" Oogie Boogie declared. "And you three...shall once again live to my bidding!"

The dreaded shadow fell over them as the three of them huddled together more, unable to stop the powerful forces overcoming them...

A little later into the late morning, approaching the afternoon, Sally had ventured off into the woods beyond the graveyard, adorned in her traveling cloak, with her sewing basket in hand to collect the herbs and mushrooms she wanted to take home. Given what the witches had told her where to find them, she had to go northwest, and travel along until she found a tree in the shape of a monstrous spider webbing with the way its array of branches spread along. Past there would be the mushrooms she desired.

Maybe I'll even find some other new kinds of herbs I can use, too. Sally thought, liking this prospect more and more.

Zero was with her as well, since he always made a point to go with her on excursions such as this, especially since she asked him to just about every time. Sally didn't mind, she loved when Zero would go with her. She knew it reassured Jack as well, since he trusted Zero to keep her safe. And if something happened, like some kind of an accident and Sally needed help and no one was around, Zero would be able to head back to town to find Jack or someone who could help her. It was obvious, but it made sense.

"Do you smell anything like this yet, boy?" Sally held the sample mushroom the witches had given her to use as a reference.

Sniffing it, Zero's nose lit up and he started to go on further ahead along the path toward the right. She smiled and followed after him.

I hope Jack is doing all right, that today's work load isn't stressing him out. She thought, lost in thought again. I wouldn't want him to come home all stressed and tired out...but at least I'd be able to help him feel better...

Sally smiled as she recalled one time when Jack came home after a long, long day's work, and was tired out and stressed, especially since the past two days at the time had been tiresome for the Pumpkin King. He had collapsed onto the couch, holding his head and groaning to himself. In a bold move, Sally went and sat in his lap on the couch, cuddled into him, and kissed his face. Within a few moments, Jack was all smiles and whispered sweet loving words into her ear, and thanked her for helping him feel better.

It was amazing to think that she could really make her beloved so happy, just by being herself and so loving to him. And really, she just could never get enough of it. Making Jack happy was by far one of the greatest and brightest points of any given day.

Sally made a note to herself to give him something special for dinner tonight, so he would surely have something wonderful to smell once he walked in the door. Sure, there was no special reason for it, but who needed a special occasion?

"Arf! Arf!"

Zero's barking snapped Sally out of her reverie, and she came to see that he stopped along a patch of mushrooms, all near that spider-web-like tree.

"Oooh...so this must be the mushrooms." Sally smiled, approaching the patch of them, kneeling down. She gently plucked one, inspected it, and then placed it into her basket.

As she gathered a few, Zero wandered off a few feet away to see what else he could find. He also caught on to a strange scent, that he just couldn't quite pinpoint. Naturally, he was quite curious and wanted to find out what it was, but he didn't stray too far away from his mistress. Whenever that would come to pass, he would make sure to either just mosey on back over to her, or if it seemed important or suspicious, he would bark for her attention to follow him.

The scent appeared stationary, but Zero was not taking any chances. He floated back over to Sally, barking to get her attention.

"Zero? What is it, boy?" She stood up, having collected enough mushrooms for the moment. She followed after the ghost dog, seeing that along the cluster of trees, there were more mushrooms along the ground, as if...leading in a line. "What did you find?"

"Arf!" Zero kept going ahead of her, often turning around so that she would catch up to him. He followed the scent, as it was getting closer. Indeed, whatever it was, it was stationary.

The trees along either side of the path grew denser and denser, blocking out the sun more and more, as if it were getting darker. Sally was puzzled. She had never been this far before, and started to want to turn back, but she wanted to see what Zero had found.

As they went along the path, more and more mushrooms were sprouted around, flourishing. All in different sizes and colours. But that wasn't the only surprising thing.

Ahead of them, was a tree that had a door on it. It was far away from the Holiday doors, and it probably wasn't even a Holiday door. The door was in the shape of a big red mushroom head, with large white spots, and it had two black eyes along the small base.

"...A door?" Sally blinked, having not at all expected to find something like this. "Where does it lead...?"

Slowly, she approached the door, very much drawn to it. She was a little anxious in doing so, and wanted to forget it all together. It was probably unsafe. Of course, there was something about it, something that drew her to it, to check it out and see what it was, where it led.

Against her better judgement and gut feeling, Sally reached out, grasping the small, golden doorknob. She turned it, and slowly pulled open the mushroom-shaped door. Peering inside, there was nothing but blackness. Endless blackness.

She turned around, facing Zero and giving a little shrug.

"WAAAUUGGGHH!" A ghostly apparition, most definitely not one of the ghosts from the graveyard, appeared before her face. It was round, sphere-like, with wide black eyes, a row of teeth, including fangs, and little arms.

Sally squealed in fright and reared back, stumbling back a few steps before she tripped on her wobbly stance. She then fell back into the open Mushroom door, disappearing into the black abyss, with the door closing behind her. Zero barked in shock and despair, and the ghost from earlier laughed and disappeared through the tree trunk.

Meanwhile, off some ways away, was the same green mist from before. Of course, this mist was now revealed to be none other than Oogie Boogie himself, in spirit form.

"Ooh-hoo-hoo...so the rag doll is all alone...and through that door!" He chuckled to himself "Won't that be perfect...bait to lure in Jack... Yes..."

With an evil laugh, he floated on back to the treehouse, an evil plan formulating already.

"When is he getting back?" Lock complained, kicking over an old can. "I'm bored silly!"

"He's only been gone for ten minutes!" Shock chided. "We can't do anything until he tells us what we need to do!"

"You'd think the first two times, he'd give up." Barrel murmured.

"Third time is usually the charm!" Lock said, and sat down on a chair. "He's Oogie Boogie, he can do it!"

"Oh hoo hoo hoo! Well now, you don't need to wait any longer, my pets!" Oogie Boogie's voice sounded as his misty spirit form floated back into the room, taking on his usual shape. "Now have I got the task for you three!"

"Tell us!" The three of them said in eager unison.

"Why it's true, as I've seen, that the little rag doll is indeed the one who stole Jack's heart!" Oogie Boogie declared, an evil grin coming to his ghostly face. The trio all nodded. "You're joking! Ah, I can't believe my eyes! How could I not see it before! Well then, certainly she will make good bait!"

"Tell us what to do, Mr. Oogie Boogie!" Shock said eagerly.

"Find her! Find her and kidnap her, bring her back to me!" Oogie Boogie declared. "She went to the mushroom patches in the forest, and disappeared through a door, also in the shape of a mushroom! Unfathomable, but true! Go through the door, find her within the other side, and bring her to me! We'll use her as bait, to lure Jack in, and destroy his spirit once and for all!"

"You mean kill her?" Lock questioned, grinning.

"Destroy!" Oogie Boogie cackled. "Jack will be broken! Have nothing more to be undead for! Without his oh-so dear Sally, he'll be nothing! My minions, my bugs! Listen well! Come with me!"

Lock, Shock, and Barrel followed after Oogie Boogie's spirit, as the equally ghostly spirits of his bugs appeared all around them. Was that even possible? But neither of them cared, of course. It just felt good to be able to serve Oogie Boogie yet again! And why wouldn't it?

They were all descending into the old underground casino lair, with the spirit of the bug creatures following along and around them. It was then also, that Oogie Boogie took the moment to break into song and dance!

"In the dark of the night
I was haunting and roaming
And my defeat was as bad as can be
It terrified me, scared me out of my wits!

All my hard work
All of my bugs falling to bits!
Then I opened my eyes
And I knew the true nightmare is ME!"

Reaching his casino, his sacred wonderful place, he was quite glad to see it still surprisingly in tact! Oogie Boogie made his way to the table, finding his two usual die sitting there, just begging to be used.

"I was once the most horrible one in all of town!
When Jack defeated me he made a mistake!
My curse will make each of them pay!
Then one certain girl got in the way!

Little Sally beware
Oogie Boogie's awake!"

Within the song and dance, Lock, Shock, Barrel and the chorus of the bug creatures joined in on the sporadic song.

"In the dark of the night
Evil will find her!
In the dark of the night
Just before dusk"

"Revenge will be sweet
When my plans are complete"

"In the dark of the night"

"She'll be gone!

They won't keep me dead for very long
Soon I will rise again to take back what is mine!
As the pieces fall into place
I will see the terror upon her face!

And to this I say,
Princess Sally Your Grace,
Farewell!"

"In the dark of the night
Terror will strike her"

"Only the least I can do!"

"In the dark of the night
Evil will brew"

"Soon she will feel that her nightmares are real"

"In the dark of the night"

"She'll be through!"

"In the dark of the night
Evil will find her
In the dark of the night
Terror comes to doom her"

"My dear rag doll
It's a sign
From here on in
It's the end of the line!"

"In the dark of the night
In the dark of the night"

"Come my pupils, my minions
Rise for your master!
Let your evil shine!

Find her!
Now, yes!
Flee ever faster!"

"In the dark of the night
In the dark of the night
In the dark of the night!"

"She'll be MINE!"

Thunder crashed and lightning struck the ground, as evil laughter, mostly drowned out by Oogie Boogie's own cackling, sounded from below the treehouse. The evil plan was set in motion, little did Sally or even Jack know, about the almost-return of Oogie Boogie.
