Desirae: Okay people, Olivia couldn't be here to post this story like she planned to do yesterday because she's busy baking a cake or something, I really don't know. Anyway, long story short, I'm posting tonight. Thanks to the people who reviewed, NattyMc, Radar180, Randomchick16, PhoenixWormwood137, Courtney, Kelly of the midnight dawn, DisneyChannelLover, and DarkChao1663. I'm sure Liv appreciated all of them. She likes that kind of thing. Now, on with the fan fiction. By the way Kelly, I'm mean because it's fun ;)

"Well this is pretty peculiar," Phineas said as he, Ferb and Isabella stared at the screen, "It says Perry's outside this café, but I don't see him anywhere, do you two?" Ferb shook his head. Isabella looked around at the tiny tables where a lone pharmacist sat staring at them, random potted plants, and the fire hydrant. But there was no Perry.

"Nope. I don't see him. Maybe be should try calling him." Phineas looked up from the Platy-Tracker in Ferb's hands and nodded.

"Yea, great idea Isabella." He stepped forward and brought his hands to his mouth to act as a makeshift amplifier, "Perry! Perry!"

"Ah, excuse me."

Phineas stopped what he was doing and he and the other two turned to look at the speaker, the pharmacist. Phineas smiled and waved at the man.

"Hi, can we help you?" The pharmacist shook his head.

"No, no, I just heard you're looking for someone named Perry?"

"Yea, he's our pet platypus." The pharmacist raised his eyebrows and his face lit up with what was probably an idea.

"You know, it's funny. I know a Perry the Platypus. Weird, huh? Does your Perry have a little secret agent hat?" Phineas laughed and shook his head.

"No, he's just a platypus. He doesn't do much. Besides, our Perry is just Perry. We don't add the 'the Platypus' part."

"Interesting…"

"Grgrgrgrgr."

Phineas, Ferb, Isabella and the pharmacist looked at the ground to see none other than the missing monotreme walk on all fours between the two speakers.

"Oh, there you are Perry." Phineas said as he bent over and picked him up, "We knew you were around here somewhere." The pharmacist leaned forward and squinted at Perry like he was trying to figure something out. The platypus blinked his unfocused eyes as the pharmacist continued to squint.

"This platypus…" he began slowly, "Is absolutely adorable! Look at his cute little platypus feet. They're so… little and… cute and… feet-y. Oh, I just love them! His eyes are pretty vacant though aren't they?" Phineas nodded.

"Yes, yes they are. Well, we should be going now. Ferb and I need to get home. Our Mom's probably got snacks ready." The pharmacist nodded.

"Of course, of course, snacks are serious business. I understand, especially if it's almond brittle. Love it! Anyway, so long Ferb aaaaaannnd…"

"Oh, that's right. I guess we forgot to introduce ourselves. I'm Phineas, this is our friend, Isabella, and my brother, Ferb." Isabella smiled clasped her hands together.

"What's your name?"

"I'm Dr. Heinz Doofenshmirtz. My friends call me…"

"Dr. D?" Phineas guessed. Dr. Doofenshmirtz blinked then nodded.

"Sure, why not? Dr. D, it's catchy. I like it. Though, it feels like I've heard that name somewhere before. Maybe someone called me that back in Druelselstein, or in a clip show or something." Phineas traded Perry with the Platy-Tracker Ferb was holding so he could have a hand free to give Dr. Doofenshmirtz a handshake.

"I'm glad you like it. Well, it was nice to meet you Dr. D," he took his hand back and waved as he and Isabella started walking homeward, "See ya around!" Isabella waved back as well.

"Bye Dr. D! Have a good day!" Ferb blinked then gently took one of Perry's paws and made him wave goodbye before following the other two. Dr. Doofenshmirtz waved to the retreating children.

"Bye fellas! And, um, fellette? Is that even a word? I don't even know. Do you guys- oh, they're gone. Huh. Nice kids, nice platypus." He drummed his finger on the table for a few seconds before something came to him.

"Wait a minute! Those kids are innocent, trusting, naïve when it comes to meeting strangers… they'd make perfect hostages! And those boys have a pet platypus named Perry, so maybe, just maybe, platypuses naturally like them. Or Perrys like them. Or maybe platypuses named Perry. If any of that is true, Perry the Platypus would be helpless to stop me in my schemes if I had even one of them." He rose in his chair and extended his hand to the sky, "To Doofenshmirtz Evil Incorporated!"

"Uh, sir?" Dr. Doofenshmirtz turned around to see an annoyed, gum-chewing brunette waitress standing behind him with her arms crossed, "You've been sitting outside here all day and you've scared away all our customers. If you don't leave now, I'm calling the manager." Dr. Doofenshmirtz waved a hand.

"Yea, yea, I'm going. I already got what I needed anyway." The waitress raised her eyebrows before rolling her eyes and walking back to man the cash register.

"Weirdo."

OOOOOOO

Perry gave a silent sigh of relief. He couldn't have gotten his owners away from his nemesis fast enough. As soon as he heard them call his name, he felt the need to get them away from here. Sure, the possibility of Doofenshmirtz doing anything in a public place was slim to none, it just wasn't his style. Usually.

But something inside was telling him that he needed to get his owners back home where it was safe. It was probably just the fact that they had been talking about him. If Doofenshmirtz had managed to put two and two together and realized he was Agent P, or "Perry the Platypus" as he put it, he'd have to be relocated away from his family, not to mention the fact that they would be in serious danger.

Sure, Doofenshmirtz wouldn't have hurt them as random children on the street, but as his nemesis' owners… Perry suppressed a shudder. He was suddenly pulled out of his reverie when they stopped in front of the Flynn-Fletcher house.

"Well, Phineas," Isabella said, "This was fun. Though, I guess I was expecting something a little more exciting from the pet of Phineas Flynn." Phineas shrugged.

"Well, he is a platypus." Isabella giggled.

"Yea, they don't do much. Oh well, I still had fun. I'd stay longer, but I've got to get ready for the Fireside Girl sleepover camping trip. See you guys in three days! Thanks again for the galaxy, Phineas. I'll keep it on me for luck." Phineas waved after her smiling.

"See you later, Isabella! Hope it brings you luck!" He turned back to Ferb, "Wow, it's gonna be weird not seeing her for a few days." The boys stood in silence for a couple seconds before Phineas clapped his hands.

"Okay Ferb, let's go inside. I know a certain silent animal that's probably near starving by now." Ferb's stomach growled and Phineas laughed.

"Not exactly the silent animal I was talking about, but I guess that still fits. Mom's usually got snacks ready right about now." Once inside, Ferb set Perry down by his bowl while Phineas scooped some platypus food into it. A few minutes later, the boys sat at the table eating their summer pudding when Candace burst into the kitchen.

"Okay, what are you boys up to?" Phineas and Ferb looked at each other, then up at their sister. Phineas shrugged.

"Right now we're just enjoying-" Candace slammed her hands on the table.

"Don't give me that! You were doing something before I left and I gotta know what it was. You guys need to be busted. Busted I say!" Ferb looked up at her.

"Well, we did track down Perry." Candace stomped her foot and pointed at them with and air of triumph.

"AHA! I've got- wait, that's it? Come on, that can't be it! I know you guys did something while I was out. I couldn't even focus on Jeremy because of you and your… doing something-ness. I don't understand how you can ruin my date without even being there with the something you did." Linda walked over to her daughter and patted her back.

"Oh Candace, leave your brother's alone. Here, join them for a snack. I have to go fold towels." As Linda left them room, Candace spun around to the now empty doorway.

"You know I can't leave them alone AND join them for snacks at the same time!" She turned back to her brothers, "Okay, so what did you really do today?"

"Ferb told you, we tracked Perry to a café downtown. We built this Platy-Tracker to find him by locking onto his DNA signature and-" Candace waved her hand.

"Yea, yea, yea, where is this so called 'Platy-Tracker'?" Phineas pointed to the device on the table next to their plates.

"Well, it's right there. We figured you would have seen it. Mom did, she said it was cool." Candace picked up the Platy-Tracker and turned it over in her hands.

"It looks like a video game." Phineas nodded.

"Yea, we designed it to be portable and easy to program. As a result, it's pretty videogame like in appearance." Candace looked down at the device again, then up at the boys and smiled her usual crazed smile.

"You guys are so busted." She ran from the room giggling like a maniac. Phineas glanced at Ferb, who crossed his eyes and twirled his finger beside his head, the standard sign for 'crazy'. Phineas snickered.

OOOOOOO

"MOM! MOM! MOM!" Candace ran into the living room where Linda was folding laundry. Linda looked up from her work and at her daughter.

"Candace! Candace! Candace! What seems to be the issue this time?" Candace threw the Platy-Tracker down on the table and dramatically gestured to it, looking back at her mom expectantly. Linda looked at the device, and then turned back to Candace with an attitude of skepticism.

"You know, Candace, if you want a videogame system like the boys, you should really use your words." Candace clenched her fists and thrust them toward the ground with impatience.

"No! No, Mom, it's not a videogame. It's a DNA tracking system thingy! Phineas and Ferb built it to see where Perry goes everyday. Look, look, look, I'll show you!" She turned back to pick up the device, only to see it vanished. At this, she screamed at the top of her lungs. Linda rolled her eyes.

"I'll admit, that's pretty weird, but it's no reason to scream."

OOOOOOO

Perry carried the Platy-Tracker away in his bill. He couldn't risk being seen again and this thing was definitely a threat to his secret. Today had been too close a call for comfort.

He walked over to the stairs and nudged the top of the bottom step open so he could drop the device into it for storage. He'd find a place for it in his lair in a little while. For now, he had a food bowl to get back to. He was pretty hungry after all. How well his owners knew him.

Desirae: Wow, thought something exciting would happen. I really hate filler. Oh well, not my problem. Maybe the next chapter will be better.
