Hi all! I'm glad to see how many people have checked out the story and are enjoying it, and I'd once more like to thank WordNerb93, PnFfan101, and LoVingYoUnOw for sending in reviews. This chapter's sort of a passing chapter, but I had to bring in Doof and Perry at least once, right? As always, I don't own Phineas and Ferb, and I hope you enjoy!

Chapter 4

"Ow, ow, okay, you win!" Dr. Doofenshmirtz cried out as Agent P twisted the evil scientist into a knot and tied his hands and feet together with some rope. The platypus then stepped back, brushed himself off, and glanced over the day's handiwork.

Perry had successfully escaped from his trap, destroyed Doofenshmirtz's "Turn-Things-Into-Harmless-Tiny-Bugs-Inator", and finally tied the evil scientist up, defeating Doofenshmirtz for the day. Even though Perry had accidentally fired the Inator once or twice into the Danville suburbs, no damage appeared to have been caused, and it looked like his work there was done. Agent P turned to leave through the lab door.

"Wait, Perry the Platypus!" Doofenshmirtz called out. "Don't go out that door!"

Perry turned and looked quizzically at his nemesis.

"You'll get rubble on my new carpet," Doofenshmirtz explained.

Agent P rolled his eyes and continued through the door. But as he stepped over the threshold, Perry found himself suddenly hoisted up into the air. He was trapped in a pet cage that had latched itself to the ceiling.

"Haha, I got you, Perry the Platypus!" Doofenshmirtz cried out gleefully. "For the second time today, too! Now I order you to come over here and untie…oh, but you're trapped too. Hmmmm…I guess I probably should have thought this through a little more."

Agent P rolled his eyes again and began to look for an escape route. Seeing the ceiling tile above him was loose, Perry kicked it upwards, causing it to fall out of place. He stuck his head up through the hole and found himself in a ventilation shaft.

"Oh good, Perry the Platypus!" Doofenshmirtz called out. "You found a way out! Now come and untie me!"

Agent P jumped into the shaft and began to crawl in the other direction.

"Yes, that's good," Doofenshmirtz said, "keep coming…hey, where are you going?"

The agent ignored the further shouts of "Perry the Platypus, you get back here!" that resonated from behind him, and continued down the shaft. He crawled until he reached a vent on the side of the building, and kicked it open. Climbing out carefully, Agent P then closed the vent, shutting out the last cry of "Curse you, Perry the Platypus!" that emanated from within. Perry found his way down the side of the apartment building and reached the ground. Then he hurried into the alleyway, jumped in his hovercraft, and headed for home.

As Perry flew over the Flynn-Fletcher house, he quickly pressed the "auto-return" button on the hovercraft and jumped out into a tree. He fell through the branches, lost his hat somewhere on a stick, and landed with a thump on the ground behind Phineas and Ferb.

"Gnananana."

"Oh, there you are, Perry!" Phineas said, noticing the platypus behind him. "We were just wondering where you disappeared to."

"Gnananana."

"Yeah, I bet it was exciting," Phineas agreed. "Well, I guess that's it for the day, Ferb," Phineas said to his brother. "We accomplished everything we wanted to do for now."

Ferb nodded and was about to head for the house when Buford rushed in the backyard, carrying a toolbox and out of breath.

"I brought my toolbox," Buford panted, leaning against the fence for support. "Did I miss anything?"

"Yeah, you missed the liftoff," Phineas answered apologetically. "I'm sorry, I didn't realize it would take you that long to get your toolbox."

"Well, it wouldn't have," Buford reasoned, "but I had to pick up the nerd."

Buford unlatched the box and Baljeet rolled out onto the ground.

"Oof!" Baljeet mumbled as he landed. Getting up, he said to Buford, "You could have at least taken out the tuna sandwich before putting me in there!"

"And miss lunch? No way," Buford answered, taking a bite from the sandwich in retort.

"Hey, where are the Fireside Girls?" Baljeet asked, glancing around. "I thought they were going to stop by."

"They did, but they left," Phineas explained. "I think Isabella might be mad at me for some reason…"

"Ah, say no more," Buford interrupted, beginning to sound oddly like a psychologist. "I understand completely. Please, follow me as I explain."

Phineas glanced at Ferb, who shrugged once more. But they followed Buford anyway as he walked into the house. Baljeet simply shook his head and did the same.

Perry rolled his eyes as they left – even he knew that Buford was not one to give sound advice in the love department.

And we'll see how that goes next time in Chapter 5...where, for those of you who are Phinbella fans, you might get a little surprise. ;) ;) Thanks for reading and please review!
