DISCLAIMER: I do NOT own Phineas and Ferb!

Perry headed into the backyard and over to the sliding door before knocking on it. He saw Phineas get up and slowly walk over to the doors, until he saw it was Perry and ran to open the door. Perry walked in before standing upright and closing the door, locking it. He and Phineas joined Ferb in the living room, his silent owner looking at something on his laptop.

Phineas looked down before gently grabbing the laptop from Ferb. "It seems you accidently activated the camera on your collar. We saw the whole meeting."

Perry looked at his owners before getting the notebook out. "You may have seen the meeting, but you don't understand animal."

Phineas looked at Ferb again before speaking. "We brought up the old blueprint of the animal translator we made last summer- remember that?"

Perry nodded.

"Ferb and I made another one about two weeks ago, but this one we made on the computer," Phineas said, showing it to Perry. "We ran the entire conversation through it, so we know what happened."

Perry stared at the two boys before shaking his head. He got out the other agents' collars and placed them on the coffee table. "So, can you fix up these collars?"

Phineas just laughed. "Of course, Perry. Now that we know how to do it, it should be easier to make them. When do you need them done by?"

"A few days," Perry wrote. "That enough time?"

"Ferb?" Phineas asked.

"Should be enough time," Ferb said, picking up one of the collars.

"So, you want everything that's on your collar, right?" Phineas asked.

Perry nodded.

"Is there anything else you need from us?" Phineas asked. "We've almost got most of your gadgets updated down in your lair."

Perry smiled. "You boys work fast. I think you've got everything then."

"What about the other agents?" Phineas asked. "They have the same gadgets as you, don't they?"

Perry nodded.

"With an eviler group of already evil scientists after you guys, I believe you guys could use all the help you can get," Phineas said.

Perry thought about that. He had a point, but Perry was still cautious on letting the other agents know the boys remember. Perry picked up his notebook and wrote, "Maybe you two can start with Pinky and Terry's gadgets and we'll go from there."

Phineas and Ferb nodded. "Sounds good. Ferb, why don't we get started on the collars. Our room?" Ferb nodded. "Then let's go."

Phineas and Ferb gathered the collars up and headed up to their room, Perry hanging back to check the downstairs out. He was in the kitchen when he glanced up and saw the time: 6:30. He wandered around, checking everything when he saw a note addressed to the boys from their mom. It said that Linda and Lawrence were driving a bit out of town to look at some antiques they heard about, Candace was in charge until they got home, but that she had a date with Jeremy at six, so she'd be gone for an hour or two. The rest just listed the cell phone numbers and the normal mom-worrying-about-her-kids stuff, to stay safe. Perry put the note back down and went up to the boys' room.

"Everything all right?" Phineas asked, looking up from one of the collars he was working on.

Perry nodded before jumping onto Ferb's bed and laying down, watching the boys work. Two hours passed by when he heard a door open and close downstairs. He slowly got up, motioning to the boys to stay, and headed over to the stairs. He peered down and instantly relaxed when he saw it was just Candace returning from her date. He shook his head and went back to the boys' room, jumping onto Phineas' bed.

"Who was it?" Phineas asked as he placed one of the collars down.

Perry nodded towards the door as it opened and Candace walked in.

"What are you two doing?" Candace asked instantly as she saw the boys working on something.

"Just fixing up these collars," Phineas said, winking at Perry.

"Fixing up collars?" Candace asked, confused. "To do what? Make people fly, turn invisible, go through walls?"

"No," Phineas said and didn't say anything else.

"Okay," Candace said slowly. "But Mom said I'm in charge, so I'll be watching you two."

"Okay," Phineas said as he started on another collar.

Candace stared at the boys for a little longer before closing the door, heading to her own room. Perry looked at the boys for a second before laughing, Phineas joining in. After they calmed down, Phineas went back to work on the collar. After a couple minutes, Perry chattered to get their attention.

"Yeah, Perry?" Phineas asked, stretching.

Perry grabbed his notebook, which was starting to run out of paper, and started writing. "Why don't you two take a break from tinkering and let's go over the taekwondo moves again."

"Really, Perry?" Phineas said. "I think we've got the moves down."

Perry gave him a look. "Get up, do some stretches, and we'll go over each move I taught you three times instead of five, okay?"

Phineas groaned, but nodded. "Fine. I know you're just doing this to protect us, but it's really tiring." Phineas started stretching before pausing. "Should we lock the door, since Candace is home? I mean, we usually practice this earlier when everybody's gone."

Perry thought for a second. "Let's go down to my lair, but lock the door, just in case Candace tries to get in."

Phineas nodded and locked the door. Perry opened one of his entrances and slid down the tube, Phineas and Ferb following him. They all landed on the chair before the boys got up and walked towards the middle of the room, where it was spacious, while Perry unplugged the webcam before joining them. They all did stretches before they started on the taekwondo moves. Two hours had passed when Perry and the boys finished going over the moves. Phineas and Ferb plopped down onto the floor, laying on their backs and breathing heavily. Perry laughed at them; he wasn't even winded. He left the boys on the floor to look at the gadgets the boys made adjustments on. He heard the boys' breathing return to normal before they got up and walked over to him.

"Sweet, right?" Phineas said. "Some of our best work, huh, Ferb?" Ferb just nodded.

Perry smiled at the boys. He was so proud of them.

"Well, it's late and I'm tired," Phineas said, yawning. "We need to get a good night's sleep if we want to finish the rest of the collars by your deadline."

Perry nodded and activated an elevator that'd take them back up to their room. Once they stepped into their room, Phineas grabbed his pajamas and, unlocking the door, headed to the bathroom. Perry hopped onto Phineas' bed and watched Ferb clean up the mess they made with the collars and placed everything in a box, storing it under his desk. Once Phineas came back in the room, Ferb left for his shower, Phineas climbing into his bed. Perry climbed up the bed until he was next to Phineas and laid back down.

"We're going to be all right, Perry," Phineas said, petting him. "Stop worrying about us. We survived the 2nd-Dimension, so we'll survive this as well. Plus, you're a kick-butt secret agent. You'll take care of us."

Perry smiled, looking up as Ferb came back in and got in his bed. Phineas gave him one last pat before turning off the light and going to sleep. Perry snuggled up to Phineas and fell asleep.
