OK! So, This one-shot has NOTHING to do with the previous one-shots. We're turning over a new leaf here. Going back to a simpler time of cobbles and chimneys. RESETing the timeline, Bleh Bleh Bleh, you get the point.
-----------------------------------------------------------------------------------------------------------------------

Bill was fly pacing alone in his room, pacing over every surface he could find.
"Ok, can anyone explain to me why, even with me being a BEING OF PURE CHAOS AND MADNESS..." Bill turned red with rage as reality around him started distorting. "...I CAN'T STOP THINKING ABOUT THAT STUPID PINES TWIN, MABEL PINES!?" An Angel Bill appeared on Bill's shoulder.
"Oh...you know exactly why, me. You know you like because she's so funny and energetic. You know you like her because of her Strange and weird behavior. Heck, even you get weirded out by her sometimes, but you love Mabel for that. Heck, dare I say you also like her because she cu-" Regular Bill flailed his arms at the angel on his shoulder, his triangular body turning extremely red.
"OK! OK THAT'S ENOUGH NOW, PLEASE!" Angel Bill dodged Bill's attack as Devil Bill appeared on Bill's other shoulder.
"What? Falling in love with a human? Cmon, you know it won't work out. She's a cute little fudgeball, your a demon of madness, it's not gonna go well, you goof." The Devil Bill then bonked Bill on the head.
"HEY! I THINK IT'LL WORK OUT AMAZINGLY!" The Angel Bill protested.
"Oh yeah. Bill should totally listen to the triangle with the skirt." Devil Bill chuckled at his own joke.
"Oh yeah? Well you know very well you have feelings for her too!"
"Pff. Yeah right. It's not like the darker ego of Bill is gonna fall for that crazy...cute little-" Devil Bill trailed off. "I SAID NOTHING!" Angel Bill snickered.
"Uh oh~, Someone's blushing~." Devil Bill turned red with rage.
"COME HERE YOU LITTLE PEICE OF-" The two Bills fought on the ground while Bill just went back to pacing.
"Ugh. What to do, what to do?" Bill said mournfully.
"OH FOR PETE'S SAKE! JUST ASK HER OUT ALREADY!" A voice cried from behind, Bill freezing in his tracks.
"Teeth, There's no need to be so blunt. I know you're as impatient as I am, but we got to let Bill prepare himself." Bill turned to see what was going on before jumping back. Apparently Pyronica and Teeth were following him from behind.
"WHAT THE!? WHAT ARE YOU DOING HERE!?!?" Bill cried out.
"Well, we heard you were talking about Mabel, and let me say that me and Pyronica here LOVE when you talk about Mabel." Teeth explained.
"I've made so many stories about you and Mabel being together!" Pyronica sighed dreamily. Bill started blushing over the fact that two of his minions were pairing him up with Mabel.
"UGH! SHUT UP! I DON'T HAVE ANYTHING FOR MABEL, OK!?" Pyronica and Teeth 'Looked' (Teeth has no Eyes, so...) at Bill skeptically.
"....Naaaahhhh." The two Henchmaniacs said in unison.
"Ok! Fine! I do....have a tiny crush on Mabel?" Bill said, his body turning red as the two Henchmaniacs squealed.
"YES! FINALLY! THIS IS A DREAM COME TRUE!" Pyronica shouted.
"I CAN'T BREATH! I'M SO HAPPY I CAN'T BREEEEAAATTHHH!" Teeth collapsed on the floor as Bill rolled his eye.
"Yeah Yeah, get it out of your systems." Bill sighed. "I wish I could tell Mabel how I feel, but how do I even approach her without Mabel freaking out!?" Pyronica and Teeth glanced at each other for a second before doing that "Wonderful, Awful idea" (I have a horrible feeling that I'll be referencing that for every one-shot I make.) Grin.
"Don't worry, boss. Pyronica's got a plan." Pyronica picked up some paper and a pen. "Pyronica's got a plan...."

Cut to Bill at a lake outside with Pyronica and Teeth
"So, explain to me, why am I here again?" Bill asked, still in the dim about Pyronica's plan.
"Oh, just a little dream boating, that's all." Pyronica snickered along with Teeth. Mabel soon arrived in a her 'Puppy playing basket ball' sweater and nacho earrings.
"Mabel! you're looking fine tonight!" Bill said, scratching  his back and sweating. Mabel frowned.
"Ugh. Bill, what are you doing here? And who are those weird...things with you?" Bill rolled his eye.
"I'm here because these bozos forced me too. This fire lady is Pyronica and this pair of teeth is...well, Teeth. And what brings you here?" Bill asked.
"I'm only here because someone gave me this note about Gummy Koalas and Smile Dip."
"Oh! That was from me. So...yeah, here's your candy." Pyronica held up a bag of Gummy Koalas sprinkled in Smile Dip.
"OOH! GIMME!" Mabel tried to grab the bag, but Pyronica held it back.
"OOP OOP OOP OOP OOP! I'll give you your candy....after you boat ride with Bill!" Pyronica yelled, Causing Mabel and Bill to blush.
"WAIT, W-WHAT!?" The two weirdos screamed in unison.
"CMON! GET ON THERE AND MAKE US PROUD!" The two Henchmaniacs also said in unison, tossing Mabel and Bill onto the boat.
"WELL! IT'S THAT TIME AGAIN! BOATIN' AT NIGHT! BOATIN' AT NIGHT! WOOHOHOWEEEEE!" McGucket exclaimed as he rowed the boat with two hot blushing messes.

"So, I saw you delivering three letters. What were the other two about?" Teeth asked, Pyronica smirking.
"Well, I felt like I needed some romantic music to really add to the atmosphere. And so, I listed the help of Earth's most vile, terrifying, and most horrifying beasts. Meet...CANDY AND GRENDA!" Candy and Grenda walked out of the forest next to the lake with some instruments.
"....Why did you insist the help of those humans again?" Teeth asked.
"They were the only one's willing to go through with the plan. It's funny how much you can get a girl to do if you have enough 'Dream boy magazines'."
"She bargained us. Those magazines were our only weakness." Candy said.
"WE'D DO ANYTHING FOR SOME 'DREAM BOY MAGAZINES'!" Grenda shouted.
"Oy, women." Teeth said, shaking his...well, body.
"SO, WHAT DO WE DO WITH THESE INSTRUMENTS?" Grenda asked in her deep voice.
"Here's the deal. I'm trying to set a romantic atmosphere for Mabel's soon-to-be boyfriend, and I need your help to set some background music." Pyronica said, handing out some sheet paper.
"Ooohhhh, Mabel's getting romantic!" Candy said, "oooo"ing with Grenda.
"OH! OH! I CAN HELP WITH THE MUSIC!" Teeth said, running up to the girls and grabbing an accordion and one of those German hats those German people wear in cartoons. "I myself have been know for playing the accordion and such." Pyronica breathed through her teeth.
"...Look, Teeth, I like your enthusiasm, but the accordion isn't exactly the best to start a romantic scene, ya know?" If Teeth could frown, he would.
"Oh. Oh, I get. You think your plan is so much better than my plan, eh? Well go on then. You'll rue this moment..." Teeth started walking away backwards.
"....Is he always like that?" Grenda asked.
"Only when he forgets to pack his snacks."

Take the most awkward moment you had. Multiply that awkwardness by 6. Add some water and a boat, and boom, you got the amount of awkwardness Bill and Mabel were feeling being on a boat with each other.
"Hehe...so, what's been going up, Bill?" Mabel said.
"Only being stranded on a boat with my cru-" Bill instantly covered his eye, which works as his mouth, so that's why he covered it.
"Oh...well, I've just been going around and...doing things with my friends." Mabel said.
"Huh. You know, your friends seem perfectly sane when compared to my friends. Let me tell you, you DON'T want to make fun of Xanther's pastries."  Bill joked, making Mabel chuckle. Meanwhile, Pyronica, Candy, and Grenda were in the bushes.
"Start the music, Girls." Pyronica said with a smirk.

[There should be a GIF or video here. Update the app now to see it.]

"The percussion!" Grenda started banging on some drums.
"The strings!" Candy started playing a violin, very terribly, but still played em good.
"The winds!" Pyronica snapped some bamboo.
"And now..." Pyronica shrunk down.
"The voice." Pyronica started crawling towards Mabel's ear on a branch.

"So...what now?" Mabel asked.
"No idea. I guess we just wait here till the ride is over." Bill replied, hoping to get this over with without embarrassing himself.
"There you see him." Bill instantly recognized Pyronica, though as of now, he had little idea on what she was doing.
"Sitting there across the way.
He don't got a lot to say,
But there's something about him...
And you don't know why,
But you're dying to try,
You wanna kiss that shape." NOW Bill recognized what Pyronica was trying to do.
"Pyronica, no! Stop!" Bill whispered threateningly, making gestures for Pyronica to cut it out.
"Bill? Why are you moving your arms like that?" Mabel asked, making Bill blush.
"Ummm, it's just arm exercises!" Bill kept making his weird arm movements in hopes to keep his white lie going.
"Yes...you want him!
Look at him! You know you do!
Possible he want you too!
There's one way to ask him." Pyronica gestured to Candy and Grenda to sing along. The girls, besides Mabel, started singing along.
"It don't take a word,
Not a single word.
Go on and kiss the shape!"
"Bill, are you hearing something?" Mabel asked, getting suspicious about these strange voices.
"HEHE! NOPE! N-NO IDEA!" Bill said, shaking and blushing.
"Alright, I think we're doing it!" Pyronica said optimistically, until another voice showed up with some Mexican music to back him up.
"SHA LA LA LA LA LA,
MY OH MY!
LOOK LIKE THE GIRL TOO SHY!
SHE AIN'T GONNA KISS THE SHAPE!" Pyronica spotted Teeth on a nearby region of the lake, singing the same song with an accordion and some French Lillputtians to back him up with some other instruments.
"SHA LA LA LA LA LA,
Ain't that sad?
Ain't it a shame? Too bad!
She's gonna miss the shape."

*Quick music break*

"TEETH!? WHAT ARE YOU DOING HERE!?" Pyronica yelled at Teeth.
"Oh, you know exactly why, don't ya? I'm making Mabel and Bill fall in love with my BETTER music!" Teeth said, smirking.
"YOU TAKE THAT BACK! YOUR ACCORDION MUSIC ISN'T THE SLIGHTEST BIT ROMANTIC! YOU AREN'T EVEN THAT GOOD WITH THAT STUPID INSTRUMENT ANYWAYS!" Pyronica ranted.
"YOU TAKE THAT BACK! ACCORDIONS HAS BEEN USED IN HUNDREDS OF ROMANTIC SONGS! I SPENT THOUSANDS OF YEARS WORKING ON THIS INSTRUMENT!" Teeth protested with the French Lilputtians.
"The fire lady is right! You sound silly with an accordion!" Candy protested.
"WE DON'T LIKE YOUR STUPID COUNTRY MUSIC!" Grenda protested with the girls. The two sides argued and fought, throwing breadsticks and fire at each other while Mabel and Bill looked in the distance.
"...Are your friends always like that?" Mabel asked.
"Yes. Yes they are. Fun fact, That's why their friends in the first place." Bill replied. Mabel spotted the shoreline.
"Hey! Seems like the boat rides coming to and end!" Mabel said gleefully.
"YES! NO MORE AWKWARDNESS!" Bill cheered, making Pyronica and Teeth stop dead in their tracks.
"....Their boat ride is coming to an end?" Teeth said.
"....And they haven't even made one real romantic move?" Pyronica said after that.
"But if this keeps going, then that means...!" Pyronica and Teeth took out a notepad and did some math, and concluded that if this kept going and Bill and Mabel make it to the end of the trip...
"OUR SHIP WILL BE SUNK! WE GOT TO DO SOMETHING!" The two Henchmaniacs yelled in unison before looking at each other.
"Truce?" Pyronica asked.
"Truce." The two shook hands.

"WOOHEE! MAKING A TRIP DOWN POSSUM TOWN, A LAND WITH POSSUMS 6 FEET DOWN!" McGucket sang before being attacked by bread sticks. "WHAT THE!? OH NO! IT'S THE MOLE PEOPLE! THEY FOUND ME! DUCK FOR COVER!" McGucket jumped over board.
"Oh no! McGucket!" Mabel cried out, but Bill stopped her.
"Don't worry. The water's shallow. There's no way for him to drown." Bill said.
"Tell that to Sergi."
"It's impossible to drown UNLESS you fall face first and are also tied up, which McGucket isn't." Bill replied. "Plus, the oars are still here. I just go and row us to shore." Bill said assuringly before the boat was hit by a ball of fire, making the oars fly away and caused Mabel and Bill to hold each other for a while before backing off while blushing. Meanwhile, the boat was heading towards a conveniently placed lake forest thing like the ones they have in the movies. Candy, Grenda, and the French Lilputtians kept playing their instruments in harmony.

*CONTINUE THE MUSIC!*

"Now's your moment.
Floating in a blue lagoon." Pyronica sang.
"GIRL, YA BETTER DO IT SOON!" Teeth yell-sang.
"No time will be better..." The two Henchmaniacs sang in harmony with some Lilputtians.
"He don't say a word,
And he won't say a word
Till ya kiss the shape." The girls and the Lilputtians started joining in.
"SHA LA LA LA LA LA,
DON'T BE SCARED,
WE GOT THE MOOD PREPARED!
GO ON AND KISS THE SHAPE! (A WHOA A WHOA!)" Things were getting more and more awkward more Mabel and Bill as the boat they were in started spinning.
"Hehe. Nice moon out tonight, right?" Mabel said.
"Y-yeah. Real nice moon." Bill said
"SHA LA LA LA LA LA,
DON'T STOP NOW!
DON'T TRY AND HIDE IT HOW!
You wanna kiss the shape! (A woah a woah)
SHA LA LA LA LA,
FLOAT ALONG
AND LISTEN TO THE SONG!
THE SONG SAY KISS THE SHAPE! (A woah a woah)" McGucket managed to surface from the water and decided to sing along too because "Why not?". Mabel and Bill, on the other hand, were blushing like maniacs.
"Bill...there's something I was meaning to tell you..." Mabel said, her face turning red.
"Really? Because There's something I've been meaning to tell you too!" Bill said, his entire body turning dark red.
"SHA LA LA LA LA,
MUSIC PLAY!
DO WHAT THE MUSIC SAY!
YOU GOTTA KISS THE GIRL!" Practically everyone there except Mabel and Bill were singing along now.
"Um...before that...there's also something...that might be totally awkward...so...Please don't hate me for this." Mabel perked her lips.
"OOOOOOOOOO!" Candy and Grenda yelled.
"Satan...why must she be so cute?" Bill swore under her breath before making his eyelids go into an lip shape.
"WOOHEEEEE! WOULD YA LOOK AT THAT?" McGucket cheered along too as Mabel and Bill got closer to...you know.
"Kiss ze shape!" The French Lilputtians kept singing, not really caring for what was going on, rather just wanting to get this over with and getting their end of the bargain after this. Teeth and Pyronica were "OOOO"ing as Mabel and Bill got closer to each other. Oh yeah, also, quick note, The boat is at shore now.
"COME ON, YOU DUMMIES! KISS THE SHAPE!" Teeth and Pyronica yelled. And you know what? The girl almost did kiss the shape....if it weren't for Mr.Overprotective sibling.
"MABEL!? MABEL,WHERE ARE YOU!?" Mabel ceased her action when she heard Dipper's voice. Apparently, Dipper was searching for Mabel ever since he found out she was going to get more Smile Dip. He's still the woods, though.
"NOOO!" Pyronica and Teeth yelled out, Teeth ripped off some of his upper mouth section while Pyronica flopped on the ground.
"Awww." Candy and Grenda said mournfully before heading off.
"Well, that sure was something." McGucket said.
"Yeah. Something terrible!" The French Lilputtians said, the two laughing at the joke.
"Oh...sorry, Bill, but I got to go now." Mabel left the boat and headed off into the forest.
"Ok then. See ya real soon, Mabel." Bill said flatly before rowing off.
"Ahem." Teeth got up from the floor to see the French Lilputtians.
"Oh. Yeah. That's right." Teeth started heading off to a golf course with the Lilputtians.
"Hey, Teeth, where are you going?" Pyronica asked.
"Oh! Well, you see, I made a deal that these guys would help with this whole thing, and I would be forced to watch their little dance for a day. So..yep. Hope I survive." Teeth headed off while Pyronica found Candy and Grenda in front of her.
"Right. You're 'Dream Boy Magazines'." Pyronica handed the girls some magazines about boys.
"Ooh. Look at Chad! He looks nice!" Candy said while reading the magazine.
"YEAH, HE'S SO HOT!" Grenda joined along. Meanwhile, Pyronica looked at Bill somberly, The latter's color scheme turning blue as he drew a shooting star on the side of the boat.
"This isn't over, Bill. Big things will happen between you and Mabel." Pyronica got out a box labeled "MABILL PLANS >V<".
"And nothing's gonna stop you two from being together."

Oh yeah. Yes I did just use that song. Oh yeah, I am addicted to Disney now. Oh yes, You can expect more horrible music numbers. Oh no, you cannot expect to be any good. Oh yeah, I am a sucker of musical numbers.
