While Trixie was sliding down the Coolest Slide Ever, Phineas kept standing at the starting point and saw other kids taking off, as well as a grown man in a tracksuit. He was waiting for Ferb or Isabella so he could join either of them, but he saw a very chipper Candace first.

"Well, you seem very happy", Phineas said.

"Of course I am", Candace replied. "I managed to prevent this slide from disappearing before five, which means I can prevent it from disappearing until Mom sees this. I can finally get you two busted!"

Candace approached the red inner tube as she continued: "I'll be calling Mom right now while I slide down."

Phineas stared silently to Candace, but then said smiling: "Okay, have fun!"

As Candace slid down, she dialed her mom's phone number.

Linda's phone was beeping as she stepped in her car. Expecting it to be Candace, she picked it up and said with a neutral expression: "Hello?"

"Mom, you gotta see this", Candace started. "Phineas and Ferb have made a bet with this rich girl called Trixie who seems really mean but is actually quite friendly once you get to know her, and she lost against my brothers as they worked until five o'clock on a really large project and now she has to be nice to every-"

Linda couldn't follow any of this and interrupted: "Calm down, Candace."

When Candace was silenced, she continued: "Okay, so you usually call me when Phineas and Ferb made something. What did they make this time?"

"A giant, very complicated waterslide", Candace said. "It's the biggest, most colorful slide they have made so far! It's got rainbow water, many pathways, a disco, a carrousel and SO MUCH MORE! Mom, you gotta meet me at the mall and I'll show you!"

Linda sighed, and said: "Alright, Candace. I'll be there at 5:30."

Linda ended the conversation. Her husband Lawrence asked: "Was that Candace? What did the boys make this time?"

"Apparently, they have made a large waterslide", Linda replied. "With a disco and carrousel. Such imagination, am I right?"

After seeing off a bunch of popular kids (including a disgruntled Remy that only glared at him), Phineas finally met his friends at the starting point: Ferb, Isabella, Baljeet, Buford, Irvung and even Perry. Timmy, Chester, AJ and Chloe were with them too.

"There you are, guys", Phineas said excitedly.

"I still don't get why we allow that Remy kid on this ride", Buford complained, who took note of Remy sliding off in the distance. "I mean, after all the things he did..."

Baljeet interrupted: "Well, Phineas likes to see the good in everyone, even in jerks. I mean why else would he still have you joining in?"

Taking offense in the last statement, Buford picked up Baljeet by his hair, grumbling: "You sayin' I'm a jerk, nerd?"

Baljeet stammered nervously: "Oh um, n-n-no, not at all, Buford, you-you are just a little rough, that is it."

Buford let go of Baljeet. "Fair enough", he said.

"Come on, guys, no need to stall", Phineas said. "Let's go!"

"BUFORD FIRST!", Buford said excitedly, taking a blue inner tube. Chester followed, saying: "I'm gonna take the labcoat of that pharmacist at the split", while taking a green inner tube. AJ, Baljeet and Irving followed suit.

Phineas picked up Perry while stationing himself at a red inner tube, as Ferb, Isabella and Chloe stationed themselves on a green, purple and yellow inner tube respectively. They haven't left yet, though, as they were waiting for Timmy, who was still standing at the starting point.

The triangle-headed boy turned his head to the bucktoothed boy and asked: "You coming with us?"

"Nah thanks", Timmy replied. "I'm waiting for Trixie to come back". Phineas then noticed that all the way down the spiral staircase, Trixie was standing there, apparently wanting to slide down again.

"Suit yourself", Phineas said as he, Ferb, Isabella and Chloe sled down.

Timmy's face lit up as he finally saw Trixie appear. He didn't beat around the bush, as he approached the asian girl and asked her: "Hey, Trixie! I was wondering if we could, umm, take this slide... together?"

Trixie was about to deny him again, but then remembered that she promised to be nicer to unpopulars like Timmy. She then remembered that she sort of kinda liked Timmy, but she couldn't see him and her dating. Not yet. She knows too little about Timmy. Right now, it's just hanging out as acquaintances.

With her popularity actually not being at risk this time, she thought hanging out with him shouldn't hurt.

"Oh, alright then", Trixie accepted. "Let's go together."

Timmy practically jumped with joy with the biggest smile on his face, as he hollered: "YAHOO!"

"But just as acquaintances: we're not on a date or anything", Trixie added.

"Darn..."

Doofenshmirtz found himself on the floor again. His groin still hurt from that impact earlier that left him paralyzed. Until some blonde kid took his labcoat that is, causing the evil scientist to be dragged all the way down by the rainbow-colored stream.

Doof was completely soaked and felt tired. He checked the time: 5:12. He wanted to go home, so he went to the closet on the third floor to pick up Norm.

"Alright Norm", Heinz announced. "Pack up what's left of the cauldron; we're going back to Danville."

"OKEY DOKEY, SIR", Norm replied. But before he did anything, the robot man asked: "SAY SIR, WHY ARE YOU SO WET?"

"Oh, I got stuck in a crazy looking water slide or something", Doofenshmirtz replied, gesturing at the water slide Phineas and Ferb made.

"THAT LOOKS LIKE FUN", Norm said. "I'D LIKE TO SLIDE THIS ONE DOWN TOO."

Then Norm launched himself in the sky.

Heinz stood there, watching Norm taking off and going through ceilings.

"Uh oh", Doof realized.

5:25. Chloe and Phineas were in the jacuzzi part of the slide, in the middle of a discussion. Ferb and Isabella were listening.

"I bet my parents will LOVE that pet of yours", Chloe claimed. "Mom and Dad are always excited about exotic wildlife, although I'm afraid they'll take Perry all the way back to Australia."

"No worries", Phineas said. "Perry will always find his way back to us. He followed us all the way to Africa once."

Isabella looked down at the bar section of the slide, seeing a brown-haired fellow with a pink cap and a black-haired girl taller than him. The mexican-jewish girl recognized them: "Hey look, I see Timmy and Trixie down there."

Phineas, Ferb and Chloe went to Isabella and looked in the direction Isabella was watching.

"It looks like they're having a good time", Chloe observed.

Phineas said: "Told ya they'd be a good couple."

"Actually, they seem more like acquaintances right now", Ferb corrected.

Seeing Timmy and Trixie reminded Phineas to check up on his other friends. He saw Buford and Baljeet on the carrousel, Chester and AJ at the disco floor, and Irving appeared to be clinging at a tube in front of the very jacuzzi Phineas was.

He also saw some other guys he now recognized since today. Veronica was at the bar too, glaring a little at Trixie for some reason. Tad and Chad were relaxing at the other side of the jacuzzi and Remy had just exited the slide.

Phineas was deliberately trying to find another person, but couldn't quite see them, so he turned to his brother. "Ferb", he asked, "do you know where Candace is?"

Candace was eagerly waiting at the mall entrance, waiting for her mom to show up. It was 5:29, so Mom could show up any minute. Despite her optimism, a small part couldn't help to be nervous as well. While she was mainly confident that the Ferbtastic Phinmazing Super Cool Slide Of Fun would stay put, the so-called 'mysterious force' she has dubbed has made the craziest chain reactions of coincidences in order to make the most impossible-to-get-rid-of inventions disappear in a flash. The cartoon theather that got up and danced away was still fresh in her mind. Even things that she didn't mean to bust her brothers for were gone in the most impossible ways, like the giant scrapbook she, Phineas and Ferb made for Jeremy's birthday.

Candace checked her phone. 5:30. Mom and Dad should be here any second, but she doesn't see them or their car. She was starting to lose patience.

Then she heard a giant splash and an equally large crash. Candace looked at the direction of the slide and couldn't believe her eyes.

Norm took about 20 minutes jumping from the closet to the slide. He was so excited that it was likely he wanted to make a cannonball, but as he finally hit the slide, he realized that, not only did he take so long that the impact was too shattering, but that he forgot that water slides do NOT equal swimming pools.

So there was the giant robot man, sitting on the floor with the scrap metal rubbish that was once the Coolest Slide Ever, floating in shallow, rainbow water, alongside thousands of kids staring angrily at him.

"OOPS. IT SEEMS LIKE I ACCIDENTALLY BROKE THE SLIDE", Norm said. "LET ME CLEAN IT UP FOR YOU." Norm's hands turned into a vacuum head and a hose. The hose sucked up the water while the vacuum head picked up the broken parts of the slide. After that, he fixed the floor that was indented by Norm's impact.

Despite that Norm cleaned up the place as if there never was a Ferbtasic Phinmazing slide, the kids were still mad at the robot.

At this moment, Doofenshmirtz has already reached his robot man, complaining: "Norm, what did you do? Now I have to pay the property damages with the alimony I was gonna use for the inator for tomorrow!"

Then Chester approached Doof, facing the kids while pointing at him and said: "Hey, it's the pharmacist I took his labcoat from! And he seems to know that robot man!"

Then an indian, bespectabled boy, Sanjay, responded: "That means HE is responsible for the destruction of the Coolest Slide Ever!"

Tad and Chad then jumped out of the crowd, as Tad said: "I say we chase 'em both down!" His black-skinned friend agreed.

The entire crowd suddenly gained pitchforks and torches while staring angrily at Doof.

Doofenshmirtz could only say: "Oh, poo", before he and Norm started to run away and the entire mob gave chase.

The only kids that remained were Phineas, Ferb, Isabella, Buford, Baljeet, Irving, Timmy, Chloe, AJ, Trixie and Veronica. And Perry.

Candace couldn't believe her eyes. The mysterious force has triumphed yet again! Phineas and Ferb, yet again, got away with inventing large things, all thanks to coincidences and pure, dumb luck.

She was so devastated that she forgot about her mom, until she heard a voice behind her.

"So, where is this 'giant, very complicated slide'?"

Candace turned around and saw Mom and Dad.
