(Author's Note)

This chapter is surprisingly long. I didn't know that it would take almost a month for me to post again. I wish I was consistent with my writing, but work work work and other stuff has prompted me to skip this from my to-do list. Anyway, this is it, Chapter 4! I do have a bit of bad news regarding the interview for Jet Engine. To put it simpler, she just wasn't interested anymore so I guess I'll just look for another one when I have a lot of time. Anyway, it's palm Sunday tomorrow, meaning it's the start of the holy week. Stay safe everyone, and have a happy holy week!

Chapter 4 "Dancing by a Public Fountain… With You."

"Isabella N-!"

Isabella thrusts the spoon to his mouth, the other hand clasped on to the end of his nose, which limited his head movement. Coltrane could not help himself but laugh out loud. Phineas squirmed on his seat upon tasting the enzymatic ice cream. Isabella giggled and enjoyed his torment. Phineas, blind because of his shut eyelids, tried to locate Isabella's arm, which is holding the spoon, but because he squirmed while searching it looked like he was flailing his arms around like some sort of dancing psycho. Eventually he got to locate that said arm and yanked it away to yank the spoon out. He began to cough exaggeratedly and rub out all traces of saliva on his tongue by means of his bare hands. Isabella in the meantime cackled like a sadist in front of him.

"Isabella! You are sick!"

Isabella giggled. "Aw c'mon! It's delicious!"

Phineas just glared... and then smirked at her. Phineas stretched out his hand towards Coltrane, the latter is confused why he did that. Phineas turned his head to him and pointed his nose towards the whipped cream bottle he's holding. Coltrane caught on to his message and smiled even more. He gladly gave it to Phineas.

"I knew you'd like it" said Isabella, taking notice of his smile.

"Yeah… And I'm sure you'd like this!"

Phineas sprayed the whip cream into Isabella's wide-open mouth. Because she was laughing, she made some choking sounds as soon as she swallowed some by accident. The bits of cream that remained stuck on her mouth were spat out. While she was coughing, it was Phineas' turn to cackle at her.

"Oh what's the matter? I thought you loved whip cream?" He mocked.

Isabella forced herself to laugh. "You're funny…"

She quickly scoops up some more enzymatic ice cream with her spoon.

"…when you're eating my ice cream!"

She made an attempt to thrust the spoon to his mouth again, but he dodged easily. He quickly sprayed the whip cream on Isabella's mouth, but her quick reaction caused her left cheek to take its place. She tried it again, but the same outcome happens. Frustrated, she dunked her right hand on the gooey ice cream and, in a stabbing manner, she thrusts it successfully onto Phineas' mouth; the latter reacted goofily disgusted. Phineas tried to yank it out but he went along the pull because her hand gripped onto his lower teeth. With no other option left, he bit her hand, despite the awful taste.

"Ow Ow Ow!"

Phineas released the bite, which caused her to fall on the floor when she tried to jerk her arm out. She shrieked as she fell.

"Woah! Are you okay? Need a hand?" He reached out a hand to her.

Isabella grabbed it and yanked it towards herself.

"Woah!" reacted Phineas.

Upon crashing, the two kids, despite their close proximity, giggled like hyenas and snorted like geeks and pigs. Coltrane, who hasn't moved an inch even, decided to laugh to the childish mischief of the pair, also because he thinks they're adorable. Only when Phineas got up a little did he pay attention to their distance. The smartest choice would've been to recoil immediately, but Phineas was so fixated on the flabbergasted Isabella and his mind encircled on just one thought.

"Sh...should I kiss her?"

Both of their cheeks flushed red; obviously she was absent-mindedly hinting that she was thinking the same thing. Abruptly a soft Spanish guitar tune was playing on his head. Phineas grumbled, trying to muster the guts to do it. He began to deliberate.

"C'mon Phineas! Kiss her and complete the patch!" said one side of his conscience.

"No! She's just my best friend! Wouldn't kissing mean-?! You know." said his second side.

"Aw c'mon, you liked it the first time."

"That was an accident. If I did it for real that would be another thing. I mean, think of the consequences."

"Consequences?! This is Isabella's dream on the line! Ya think she'd forgive you if you failed?"

Phineas' second side of his conscience sighed. "But how do I do it, the patch I mean? We didn't get it the first time. I mean, we don't even have a recording device to begin with."

"Yes you do! You have ARChie!..."

Both sides of his conscience gasped. "ARChie!"

He jolted from Isabella and whistled loudly as if he was calling a taxi. The camera "ARChie" gradually descended to Phineas' open palm, beeped a few tones, and folded its propeller back inside itself. Happy to have ARChie return to him, he stowed it in his pocket.

"I almost forgot that he was running the video." Phineas chuckled. "Wouldn't want him to run out of battery."

He looked at the sat-up Isabella, who is still trying to register the moment she just witnessed. Phineas' guilt kicked in, and the thing he regretted made him blush.

"Are you okay?" he asked.

Isabella blinked, seemingly awakened from her fantasy. After a few blinks more, her face succumbed to disappointment.

"Yeah I'm okay." She responded blankly.

And he knew she was lying.

"See. I told you, you should have kissed her."

"Yeah right." He said softly to his conscience.

"What?" Reacted Isabella.

"Nothing! Nothing."

"Oh." She responded.

Phineas gulped. "Why me?!"

He sighed. "Isabella…. Do you really want me to-!"

Suddenly some sort of electronic bell dings for about three times. All three, who were present in the store, looked up to the digital clock that hung on the wall above them.

Isabella gasped. "W-what?! Eleven already?! Oh no! We're running out of time! C'mon Phineas! Let's go!"

She hastily got up, ran towards the direction of the door and grabbed Phineas' arm along the way, the latter was dragged towards the door and his head was bumped on the glass.

"Oowwww!" he exclaimed in pain.

"Oh! Sorry! C'mon get up! We gotta move!"

"Oh! Uh, see ya later Coltrane!" said Phineas hastily, while rubbing his head.

"Have fun you two!" Responded Coltrane.

Agent P, Perry the Platypus, piloted his hovercraft across Danville residences. If one was to ask why, it was to travel to that old weird looking building in order to deal with his old and usual nemesis…. Again. That's no exaggeration. Perry the Platypus had founded that his current career is so awfully routine, that he began to think of it as dull. And yet, on the other hand, the job had been too important to ignore in all his life, for if Dr. Heinz Doofenshmirtz were left unchecked, his diabolical schemes could potentially twist the current state of reality into an unspeakable, and yet ridiculous, horror. Something glinted, from sunlight, on his chest. Perry held it with his palm and clicked the central button with his thumb. The tangerine webbed foot locket unfolds, revealing three photographs of Phineas, Perry and Ferb respectively when they were little. To him, it was funny. Those moments between him and them seemed not too long ago, in fact it was as if it was yesterday.

"You are now, and always have been a great pet, and a great friend. We're going to miss you, Agent P."

He clasped the locket close to his chest, folding it back in the process. Internally, he motivated himself by recalling the real purpose as to why he does what he does best, Phineas and Ferb. Fiercely, he fixed his hat up, so that the front of his hat no longer hid his eyes. He pushed the throttle lever to the end; the engines blasted from red into blue plasma flames.

The TV screen right beside the yoke went static as Perry turned it on, Major Monogram eventually appeared.

"Good morning Agent P! Sorry to interrupt your morning sleep in."

Perry chattered angrily.

"Yes yes! I'm sure you will enjoy your beauty sleep once you finish cracking up this mission. And guess who you will be assigned for today."

Perry glared at him blankly.

"Wh-what?! D-don't give me that look! You haven't even-!"

Perry showed the classic photograph of Doofenshmirtz, the one with the beach background.

"Oh!... Well, I supposed it does get a little dull being assigned to the same mission over and over…. Well, you've got no choice. He's your nemesis after all, meaning he's your responsibility."

While Major Monogram said those last two words, Perry was imitating his voice with a "blah" each time he uttered a syllable (six times in total).

"Agent P! Focus!... And report to me after this mission. We have to talk about your behavior."

Perry sighed.

"Anyway, recent reports stated that he has purchased a giant cassette player, or boom box as the common folk say it. He's also purchased a list of items: one laser gun, multiple cable wires, numerous metal plates, bolts & nuts, and an mp3 dock. We're assuming that he's making a contraption that involves music, so be sure to plug your ears at the right time agent P! Good luck!"

With the conclusion of his briefing, Perry saluted to him. He turned off the monitor and resumed his driving. Shockingly, he was already a few meters away from his destination. He adjusted the throttle lever backwards so as to slow down his vehicle, pushed the red button to activate the automatic pilot mode, and jumped off the vehicle. One of his favourite parts about being an agent is that he gets to do cool dangerous tricks, such as skydiving, which he is doing now. A small window just happened to be close by, so he dove right into it. Thankfully it flipped open, he was scared to think about the price of a broken window. But the next thing he felt was an incredibly stingy yank right on the root of his tail. Tears dropped from his eyes. The next thing he knew, everything was black.

Phineas and Isabella walked along the sidewalk, with no particular direction to go. Holding the handbook while walking, Phineas decided to take one more evaluation of the patches that require their attention.

"Okay! So, just to recap everything, we have to complete all ten patches! Where do you want to start Phineas?" Asked Isabella.

"You're asking me?" Asked Phineas.

"Yeah, just to make a decision of course."

"Hmmm, how about this one? It looks fun!"

"What's it say?" Asked Isabella.

"The Start a Harlem Shake Patch!"

"Oh!" She giggled. "Sure! I got my speakers and my MP3 player dock right here!"

Phineas looked in suspicion at her satchel, the one she showed him.

"Say, where did you get that?"

Isabella looked a little confused. "Oh you mean my satchel? I had it with me all along! A Fireside Girl must always be prepared!"

"Really? I didn't see you pick that up before we left the house."

Isabella got a bit annoyed with his doubt. She walked up to his front and stopped with hands on her hips.

"What? This satchel came to me like magic?" she said sassily. "Oh please Phineas, it's not like ARChie wildly appeared on your side table this morning after you woke up."

With that said, she stomped away leaving Phineas speechless and skeptical about his own assumptions. After a few moments of thinking he smiled, impressed.

"Touché Isabella. Touché."

He ran to catch up to the stomping Isabella headed towards the park, along the way he pushed her playfully to provoke her to chase him.

The park was beautiful as usual; the evergreen trees, the flowers, the playground, the vast lake, and all the others were able to take part in its glamour. There were lots of areas where you could have a place of your own to hang out, but today it seemed that those spaces were diminished to limited slots thanks to the extra crowd. But that didn't seem to be a problem for the two, quite the antonym in fact. All the kids needed was a place that would make the crowd audible to what they plan to broadcast, somewhere that's central to the audience.

"You think everyone would be able to hear us when we get to the fountain?" Asked Isabella.

"Not totally accurate, but it would be pretty close, like ninety percent of the people in the park."

She swooned. "I love it when you talk nerdy."

There was a moment of silence, awkward silence, between the two. Isabella wondered why, then it occurred to her that she flirted with him. Bewildered, the girl, with a shivering head, turned to the confused Phineas. After a few moments though, he seemed rather flattered and he grinned lop-sidedly.

"Thanks! I guess." said Phineas.

They slowed to a walk as they approached the fountain. Isabella, with a sense of achievement, balled her knuckle under her chin and smiled cheekily.

"I think this is a good spot! Come on! Let's get shakin!"

Isabella giggled. "Coming!"

Isabella happily skipped over to where Phineas was and began to set-up their sound system. There happened to be a plug there so she plugged in her speakers and set her MP3 player to its dock. Phineas activated ARChie from his pocket, and the device flew to the sky like a tiny helicopters, he then stood on the ledge of the fountain so that everyone would catch their attention.

"Hey guys! We're gonna start a Harlem Shake today! Who wants to participate?" said Phineas aloud.

He was able to catch some of the other people but they were too hesitant or shy to join the said activity, besides it was not in their itinerary to do so. Phineas felt hurt and stupid because of their ignorance. Isabella started to feel despaired as well. But Phineas, like the optimist he is, thought of what could be a solution to their problem. He looked at Isabella.

The young girl's raven black hair reflected the sunlight that it shined brightly. The wind blew it at her way, making her hair flap.

"Hey Isabella! Could you come over here a sec?"

Isabella, saddened, approached the confident Phineas. Phineas urged her closer as if to tell her a secret. She leaned her left ear close to him.

"Use your cuteness to mesmerize the townsfolk." Whispered Phineas.

Isabella's eyes widened. "Wait, what did you say?!"

Phineas chuckled. "I said use your cuteness to them. You've got the cutonium in you right? Use it to our advantage! You know, do your thing!"

Isabella blushed then smiled cockily. "Oh I don't know. You might fall under the spell as well."

"If it gets too powerful I can just close my eyes."

Isabella chuckled. "Oh-kayyyy!"

Isabella happily skipped closer to the people hanging out in the park.

She cleared her throat and spoke in a slow angelic voice. "Um, hey guys!"

As soon as her voice echoed the through the park everyone turned to her. She turned her head to the right, eyes closed, and her hair hid her face briefly. Slowly she turned to the crowd and opened her sparkling eyes.

"Watcha doin?" She said confidently, with a hint of shyness.

Phineas' pupils widened to her cuteness, luckily before he got more hypnotized he blindfolded himself with his right hand, but on second thought he parted his middle and index finger for his left eye to peek. The rest of the audience had the brief reaction Phineas had; huge pupils, drooling mouths and incredibly awestruck.

Isabella giggled. "Hey guys!"

"Hi! Whoever you are!" They responded slowly.

"You guys wouldn't mind if you take part in our Harlem Shake dancing would you?"

Suddenly they snapped out of the hypnosis. "Err… I don't know. I mean-!"

"Oh pleeeeaasseeee take part on our dance. Pleeeeaaaaassseeee!" She begged innocently.

Their hypnosis state resumed. "Awww, okay whoever you-!"

"Isabella. The name's Isabella. Now could you guys stand up and group up with my best friend Phineas over there?"

Phineas waved to the crowd, his hand still blindfolding him.

"Suuuurrreee!" They replied like mindless zombies.

"Thank you!" She ended her trick with a giggle.

She walked back to Phineas. She gently placed her hand on the blindfolding hand.

"You can open your eyes now."

Like before, he peeked through the space between his middle and index finger. A bunch of people started to approach them. Phineas finally lowered his hand.

"How do you do it?" asked Phineas.

Isabella chuckled. "Like you said, Cutonium!"

Some random boy approached Isabella bashfully.

"Uh, Isabella? Th-that's your name right?" Asked the boy.

"Uh-huh." Said Isabella.

"Could you be my girlfriend?"

The two best friends jumped in surprise.

"Wh-what?!" reacted Phineas. "You just met her today!"

"B-but I believe in love at first sight! Y-you do too Isabella, don't you?"

"Wha-!... Okay, what?!"

Isabella on the other hand is taking this really well, since her companion reacted violently.

"Aww, you're sweet, but sorry. I believe in the love at long-lasted relationships more." Said Isabella.

Phineas' expression lightened with her response. Sadly the boy seemed a little heartbroken.

"Y-you don't feel…. The same way?"

Isabella giggled, and decided to peck him on his right cheek. "Consider it a gift, for being so sweet."

Both Phineas and the boy were shocked, the latter stuttered a few syllables and then swooned to the ground.

"C'mon Phineas! Let's go get that patch!" she said, pulling Phineas' arm along.

"Oh, uhh, okay." He said, still mind blown.

She went over to where she parked her MP3 dock. The two kids stood over the ledge to survey the amount of people that are participating with them. Sadly it wasn't as much as their targeted amount. According, to the Fireside hand book, it has to be ninety percent of the area's population and according to Phineas, they only had five percent.

"I can't just use my cuteness over everyone, I mean acting cute can drain you ya know." said Isabella.

"Maybe if we start dancing it would catch everyone's attention."

"Well, better test out that theory then! Hit it buddy!"

Phineas scrolled through the songs of her MP3 player until he finally found the one he was looking for: "Baauer – Harlem Shake." He played the said song.

As soon as the beats came in the two kids started to dance, the rest of the audience just did their thing, talk to each other, hangout, and other stuff that pretended to not acknowledge the kids. As the beat accelerated their dance moves got more intense. Upon arriving at the base drop, some sort of purple beam fired and enveloped the whole park. The next thing they knew, everyone was flailing their arms around like crazy people, including the animals. The hotdog stand owner was spraying mustard in the wrong places, the fishermen were trying to yank their hooks from the fishes in the lake, which were also dancing, in a wild fashion that involved flailing it and your arms around, the kites started to follow the movements of the kids who were using them, lastly the roller skaters could not skate very well but even if they did fall down they would still dance. Others did the worm, others vibrated their bodies intensely as if they were electrocuted, a fisherman decided to use his dangling fish as a punching bag, and some parents decided to spin their kids around with their arms.

"Wow! It worked!" Exclaimed Isabella.

"Well that escalated quickly."

Suddenly Isabella's dance moves started to intensify, much to the boy's surprise.

"Whoa! When were you this good at getting down?" asked Phineas.

"Umm, now." She said. "You're not so bad yourself."

Phineas started to wiggle his arms and legs as if they were jelly. Phineas wanted to stop dancing… But for some reason he could not control his own movements anymore.

"Uhh, could you stop for a sec?" asked Phineas.

"Uhh, no?!" Exclaimed Isabella. "I literally cannot stop! Agh!"

She somehow slipped to the fountain, but Phineas' dance moves enabled him to catch her… and waddle her like a doll.

"W-what's g-g-g-goin o-o-o-on?!" she yelled.
