"... And it's still loading…" Doofenshmirtz stared at his -inator, "Man these things take forever! I should make a 'Speed-up-loading-inator,' although then people could use that for good, and then it wouldn't be evil…"

While Doofenshmirtz was distracted, Perry slowly started to unscrewing the bolts holding his trap together.

"And now, ladies and gentlemen!" Irving announced, "Ferbettes and Platypuses!"

"And my sweet Susan Test!" Eugene put in.

"It's time for the race!" Irving said. Eugene handed him a paper, "Oh, I almost forgot!" Irving shouted, "Eugene ("It's Bling Bling Boy." corrected Eugene,) and I have made a rule change to the rules!"

"Oh, come on!" yelled Candace, "You can't just change the rules!"

"But Candace, this will be more intense!" Irving said excitedly.

"Let us explain," Eugene said, oblivious to the ugly look Susan was giving him, "We will combine the two tracks together, by setting them side by side. Of course we'll have to remove the railings from each one." Everyone looked at Team Danville's track. It was the only one with railings. "... But this way you can race side by side with your opponent," Eugene continued, "and it will feel more like a competition. You can switch between the tracks with no trouble at all."

There was an awkward pause.

"Sure, yeah, I can go with that." Isabella said.

"I'm in." mumbled everyone else.

Mrs. Flynn-Fletcher was at the grocery store, looking through the aisles for what she needed. But something felt wrong. She checked her phone. No calls or texts from Candace.

"Huh, that's funny," Mrs. Flynn-Fletcher said aloud, "Usually after I tell Candace I'm too busy to come see what the boys have done, she comes and drags me out of the store. I wonder what they're doing right now."

"Everyone to the starting line!" Irving called.

Candace pushed everyone aside as she carried her hoverboard in one hand, and marched over to the starting line. She was ready for Phineas and Ferb to pound the pharmacists. She was ready to pound the pharmacists. She was ready to bust the boys as soon as the race was over.

"Hey, Candace!"

Candace turned her head, and almost had a heart attack.

"J-J-Jeremy?" she gasped.

"Hi Candace," Jeremy said again, "I heard you were having a contest, so I came to cheer you on."

Candace stared at her boyfriend, sweating profusely and debating with herself.

"JEREMY!" she yelled.

"Uh, Candace are you okay?" Jeremy asked, concerned.

"I mean– Jeremy," Candace said in a fake sweet calm voice, "Will you join Team Danville in a hoverboard contest against Team Porkbelly?"

"Uh, sure Candace," Jeremy replied, "I love playing the sports your brothers invent."

"Great!" Candace grabbed him and took him to Phineas and Ferb, "Suit him up, Phineas!" she commanded.

"Sure thing, Candace." Phineas smiled as he led Jeremy over to where a pile of hoverboards lay, (they had already dismantled their hoverboard-making machine,) "We weren't sure how many we would need, so we made a lot of extras," he told Jeremy, "Take your pick."

"That is a lot of hoverboards." Jeremy commented.

"Wait a minute!" Mary said, "If you get one more player on your team, we get one more player on our team."

Right on cue, nobody other than Gil Nexdor walked right in the backyard and right over to where Johnny was standing.

"Gil Nexdor…" Susan and Mary sighed.

"What's up, Johnny Bro." Gil said, "I heard you were having a contest."

"Who the heck are you!" Candace yelled.

"He's our next door neighbor." Johnny explained.

"Or he was…" Dukey said.

"Shut up, Dukey." Johnny replied.

"Hi long necked girl." Gil said, trying to flirt with Candace.

"Okay, ew." Candace backed away.

"Oh, come on!" Susan and Mary yelled.

"Welcome to my world." muttered Isabella.

"Okay, so we have Jeremy, and you guys have Gil," Phineas said, "So now the teams are fair again."

*Doofenshmirtz Evil Incorporated*

"Could this thing load any slower." Doof sighed. A ding sound came from the computer. "Oh, hey! The system update's done!" the evil scientist cheered. Then his smile fell. "... And now I have to wait for the -inator to charge up…" he stared at it for awhile. "Hey, Dark Vegan?" Doof called, "Do you have any toast left?"

Perry pulled out a screw. He looked over to Mr. Black and Mr. White. Perry made a chattering sound.

"I think he wants us to do what he's doing." Mr. White said.

Perry nodded, and continued to unscrew another screw.

"Everyone to the starting line!" Irving announced again, "Make sure you have the proper protective gear on!" Everyone looked at Buford. He wasn't wearing a helmet. "Oh, fine!" he muttered as he put one on.

"On your mark." Eugene said.

"Get set!" Irving cried.

"GO!" Irving and Eugene screamed at the same time. The race was on.

Candace zoomed across the track on her Ducky Momo hoverboard, with the wild determination in her eye, she usually reserved for busting Phineas and Ferb. She dodged obstacles here and there, and slid beneath an overhanging bar.

Susan and Mary raced side by side, as they caught up to Candace. They were wearing racing outfits, their lab coats forgotten.

"Who's a pharmacist now?" Susan called as she and Mary slowly passed Candace.

Isabella hurried down the track, avoiding giant logs, hung by a chain, and swinging from side to side, Sissy came up beside her, and they each tried to pull ahead of each other, and then suddenly Sissy fell onto Team Danville's track, avoiding a low bar, but seeing the Fireside Girl logo as she passed.

Buford and Bumper were neck and neck up against each other. Bumper punched Buford, and Buford punched him back. Baljeet was screaming as he went over a long drop.

Jeremy and Gil were gliding side by side.

"Hey, you're pretty good at this." smiled Jeremy.

"Not so bad yourself, Dude." Gil replied.

And in the lead was Phineas and Ferb, dancing to the racing music that was playing, ("Another indiscernible music source!" Candace pointed out,) they jumped over obstacles, switched hoverboards, and switched back again.

"Oh, yeah, this is what I'm talking about!" Phineas cried.

Ferb gave a thumbs up.

Johnny and Dukey were racing not too far away.

"Oh, man, this is AWESOME!" Johnny cried.

"Woo hoo!" yelled Dukey.

Phineas and Ferb pulled next to Johnny and Dukey.

"This is awesome!" Johnny cried again, "You guys are better than my sisters. You must really want to win!"

"We don't do it for the competition," Phineas explained, "We do it for fun!"

"Speak for yourself, Phineas!" yelled Candace.

"My sisters hardly do anything for fun." complained Johnny, "That's why I steal their inventions."

"You don't need inventions to make the most of every day of summer," Phineas pointed out, "It's just about having fun!" then Phineas broke into song "Suuuummer is running through the sprinklers in your T-shirt, shoes, and jeans-" he paused. "That's the second time I've sung that song, and I still don't know where I learned it." He and Ferb looked like they were having an existential crisis..

"They are nothing like your sisters." Dukey told Johnny.

"Your toast is ready, Sir." Norm announced to Dark Vegan.

"Ooh, toast!" He grabbed a ton of slices, "Can I borrow your robot?" He asked Doofenshmirtz.

"I don't know," Doof replied, "He's kind of weird, I'm not sure you'd like him."

"Would you like some garlic ice cream?" Norm replied.

"I was saving that for later!" Doof took the carton away.

"I'm good." Dark Vegan said hastily.

I hope you guys like this chapter, it was harder to write than I thought it would be. TheEdsRock suggested I have Jeremy meet Gil, and Linda and Lawrence meet Hugh and Lila. Jeremy was supposed to meet Gil earlier, but I forgot about that XD, but the Flynn-Fletcher parents will meet the Test parents, because I thought that was a great idea. Somebody else suggested I make another JT/PF crossover, but this one with romance between characters from each town. I'm sorry, but this is the only Johnny Test X Phineas and Ferb I'll do, unless this is popular enough to do a sequel, and I'm not going to have romance between them, because each world has it's own funny thing going on with romance. (e.g. Phineas not noticing Isabella's obvious crush on him, Gil not realizing Susan and Mary have giant crushes on him, the whole thing with Eugene, etc.)

But if you have an idea for this, don't be afraid to leave a review or a PM, all kinds of feedback are appreciated :)
