You would've never guessed that the giant, black, triangular monolith turned nightclub was once used as a castle to strike fear into the hearts of others. But, things have changed over the course of five years. Inside the structure, out on the dancefloor, people, and even demons, danced to music; neon lights flashed; purple and black streamers hung suspended in the air; and huge bean bags and lounges wrapped around the main dancefloor. The party was outstanding.

Luna, the only one not in the fray, sat in a purple bean bag against a black triangular pillar, watching the party. She smiled to herself; silently thanking Mabel and Bill for organizing such an amazing birthday party.

She had to hand it to them; for Bill to create a Time Bubble dedicated to Weirdmageddon, complete with an exact replica of the Fearamid was a feat. But then for Mabel to decorate it with purple and black, plus for Bill to supply lights, food, drinks, a DJ, and the like was nothing short of amazing. Plus, Mabel and Pacifica made Luna a special black and purple lace party dress; complete with purple glovets and black mini boots. All evening, it was nothing but happiness, celebration, energy, and excitement. Well, almost.

As Luna looked back at the crowd, she slightly frowned at a sad reality; everyone had a partner. Dipper was dancing with Bell; Mabel was with Pacifica; even Tyrone was standing off to the side with Will. Heck, even Luna's friends from school and the Underrealm were all dancing together. But, she was alone, one of the people she wanted to see wasn't out there: Bill.

Luna had been waiting for the demon to arrive for most of the party; she's tried interacting with her friends and guests to bide time, but she couldn't shake the fact her personal VIP wasn't with her. "Where are you, you crazy equilateral?" She whispered that night. "Hey! Luna!" A male voice called, pulling Luna from her thoughts. She perked her head up, hoping it was Bill. Instead, she saw a stumbling male brunette, break away from the thrall, and leaning against one of the triangular pillars for support. Just by seeing the open red-and-black flannel shirt, white tee, ripped jeans, and blue-and-white pinetree cap; Luna could tell it was Dipper.

She hopped out of the bean bag, and jogged over to the brunette, heels clicking against the floor as she ran. Catching the edge of the same pillar, Luna looked at her friend with a half smile. Dipper then looked up at Luna, with his own smile; his face tinted pink, small beads of sweat forming against his skin, and his visible brown bangs were matted down against his forehead.

"'Having fun out there?" Luna panted. The teen sighed, glancing back at the crowd for a moment before looking back at Luna. "Bell is, but it's too crazy for me." Dipper then pressed his back against the pillar, and slid down until he was seated on the black floor. "Heh. I know how you feel, man." Luna followed suit, sitting next to her friend with her legs folded. "Well, you should've seen some of the stuff that happened out there." "Oh, really? Regal me of these mishaps, O brave little Pines." "Heh. Well.." Then Dipper began telling Luna about what he's seen out on the dancefloor; including "drunken" shenanigans, failed challenges, and general playful chaos.

"So, back to my question," Luna said, glancing at Dipper. "Are you having fun?" "Huh? Oh, y-yeah! The party's great." The pair then laughed wholeheartedly, before the teen asked, "Are you?" Somehow, that stopped the joyous moment, and reminded Luna why she was feeling left out at her own birthday party. She paused for a moment before looking back at Dipper with an annoyed, blank face that said "No." Dipper blinked. "It's because Bill hasn't shown up yet, right?" 'You're always the master of the obvious, Mason.' Luna thought to herself.

She set her chin in the palm of her hand as she looked back at the dancing figures longingly. "He's the only one I didn't see out on the 'floor." She sighed. The din of the party suddenly toned down as the song that was playing ended. "Well, maybe things'll get better for you." Dipper quipped. Suddenly, the soft feedback of a microphone squeaked around the room as the DJ on stage tested the mic. She was standing on a stage in front of the dance floor behind a turntable, wearing sleek clothes, headphones resting around her neck, and wore purple sunglasses.

"Hey, guys! 'Hope you all are enjoying the party." She called, met with cheers from the crowd. Dipper and Luna listened closely along with the other partygoers. The girl pushed up her purple shades as she continued to speak. "Okay, we're gonna start taking song requests! This first song is-oh." The DJ suddenly paused to look the card over, causing confusion among some of the guests.

"Sorry about that, guys. Our first song's dedicated to the birthday girl herself. 'To a girl who's outrageous and indestructible'." A chorus of playful 'oo's' bounced around the room, causing Luna to blush softly. "Luna, come on up!" The female DJ waved onstage for Luna to come forward. Another chorus of shouts of encouragement, and even whistles, rang out; egging on the pressure.

Luna's face was flushed pink with embarrassment; she was known for having moments of shyness, especially if someone called on her for something. She turned to Dipper for support. "Should I?" She whispered meekly. The brunette said nothing, but tipped his hat with a nod, and reassuringly smiled.

"Knock 'em dead, Lulu." He whispered back; Dipper was one of the select few who knew and called Luna by her childhood nickname. She nodded; rising to her feet, met with claps, whistles, and other calls of approval. As she walked forward and out to the dance floor, the DJ onstage smiled. "Alright. Everyone enjoy Irresistible by Temposhark!" The teen flicked a switch on her turntable as the song began to play.

As she walked out onto the dance floor, Luna smiled as her senses were treated to the familiar tune. Whoever requested the song knew her well to know one of her favorite songs. She moved her body, and even spun a few times, as she glided to the center of the dance floor, softly singing along to the song.

Heels like pistols, gotch' you on tiptoe,

Ridin' high with a loaded smile~

Makes me laugh, you are such a joker,-

'Cept when you joke, but you're cruel to kind~!

A voice sang out. Suddenly, someone ran at Luna and they collided, causing her to wince in surprise. They then caught her, spun her around, and dipped her, halting mid-dip. The music abruptly stopped, and Luna could hear hushed murmurs, and whispers. She was too afraid to open her eyes, until a voice whispered coolly, "Am I too late, Moonstone~?"

Moonstone. There was only one entity who called her 'Moonstone' with confidence. Luna opened her eyes with a gasp, but then smirked seeing who held her. It was Bill; smiling down at Luna with his trademark grin, and a glint of mischief sparkling in his golden eyes. As she quickly looked, Luna saw how Bill cleaned up for the party.

Bill had his golden blonde and black hair combed back, and his small black top hat floating above his head. He was wearing his usual formal attire; a white buttoned-up dress shirt, gold vest, and black gloves, dress pants and bowtie. Bill then brought Luna back onto her feet, smiling. "Didja miss me~?" He whispered. Luna smirked back at the demon playfully. "You're a little late, Prince Charming~." Luna chided, her voice laced with a playful tone. Bill sighed softly, drawing Luna closer to him, and kissed her head softly. "I'm sorry, Moonstone. Is there some way I can make it up to you~?" He purred in a sincere tone.

Luna looked up at her partner, and then glanced at the crowd of whispering, murmuring partygoers. She looked back at Bill. "Give me this dance, a drink, and we'll call it even. Deal?" The demon responded with an answering smile. "Deal." The two then locked hands, as Bill's blue, wispy flames lit their hands, sealing their deal.

As the flames dispelled, Bill looked up to the DJ with a nod to resume the song. The music began to play again, as the pair started dancing with the others trying to copy their swift movements. Luna and Bill had practiced a dance for this song; moving with smooth shuffles, sharp snaps, and fast dips, and twists. And for those swift minutes, the whole party was that much more exciting.
