"Okay, Agent P. Just sit right up there." Carl patted down a spot on the O.W.C.A examination table.

Perry gave him a skeptical look.

"I know, Monogram usually does this. But I've been studying! And maybe I can get promoted to vet!"

"You can't, Carl." Monogram said. He was sitting nearby, reading a book.

"Anyway, let's get your vaccine over with." Carl went to the cupboard.

Perry sat down on the table and looked at Monogram's book, "Behind the scenes with Ducky Momo".

"Okay." Carl picked up the shot and pressed it so that a little bit of liquid squirted out the top. "Now what, sir?"

"Carl, why did you just do that?"

"Do what?"

"Push some of the vaccine out?"

"You always do that!"

"Only if it's over the amount that it needs to be! The amount was perfect! Now you have to set it up again!"

Perry was starting to wonder if he should be concerned.

Carl sighed and tried again. "Okay. Now I give it to him?"

"NO, Carl, you have to clean off a spot on his arm first. PLEASE do this correctly so I don't have to keep looking up. This is an interesting chapter: 'The rise of Ducky Momo.'"

Carl cleaned off Perry's arm with cotton. "All right, Agent P. Ready?"

Perry held out his arm and covered his eyes with his free hand.

"You know, if I get really good with medicine and stuff, I may be able to graduate so I can become a vet."

Perry waited.

"Then I might give you your shots whenever you needed them."

Perry opened one eye and glared at Carl. Carl was just standing there, holding the shot, and gabbing away.

"Maybe I could even-"

"Carl!" Monogram barked. "Look at the poor thing! Just do it so he doesn't have to worry about it any more!"

"Okay, sir! Sorry."

Perry closed his eye again.

"CARL! KEEP YOUR EYES OPEN!"

"Sorry, sir. It's hard to watch!"

"Just do it!"

Perry winced as he felt the sharp pinch. When it was over, he uncovered his eyes.

"There you go. You're good for two months now!" Carl said cheerfully. He went over to the trash can.

"CARL! Put it in the sharps disposer!"

"Oh. Right. Sorry, sir." Carl corrected his mistake. "Take any bandage you want, Agent P. They're on the cart over there. So, Monogram, who's next?"

"No, Carl, I'll do the rest of the job today." Monogram growled. "I'll read my book later."

Perry stuck a clear bandage on his throbbing arm and left the room.

Greeting him was a huge sign, covered in sparkling orange glitter with a big pumpkin on it.

"COME TO O.W.C.A'S HALLOWEEN BASH! OCTOBER 30!" It said.

Darren the duck was holding the sign. He grinned at Perry. "Isn't it amazing?"

"That is one epic sign." Perry admitted.

"I bet it's gonna scare Carrie senseless." Darren said.

Carrie the cat was very skittish. She'd gone to Disney once and had been thoroughly terrified by the merry-go-round.

"Are you going to the party this year?" Darren asked.

"You know how I am with parties."

"There's gonna be cupcakes!"

"Cupcakes are a crime against cake." Perry said.

"Come on, Perry, I'm planning it this year. I promise it won't be awful."

"It won't be, Darren. I just don't like parties."

"You like cake, right?"

"Yeah, but…"

"And you like cookies?"

"Everyone loves cookies."

"Good! So you'll go. Now help me think up scary stuff for it."

"I can bring Candace's old clown toy."

"Not Carlos the caring clown again."

Perry nodded. "Oh yes. Last week I stuck him in the microwave. But guess what? After he exploded, he magically went back together! I think Phineas bought a new one again…"

"Didn't you explode the first Carlos in the toilet?"

"Yeah. World's best flood. Only rubber duckie survived. Hey, you want scary? Stick pictures of violent, gory…"

"I'm not allowed. It has to be G rated."

"Then put up a picture of a unicorn."

"Unicorns are not scary."

"Are you kidding? That pointy horn could stab you! And glittery, cheerful things are ALWAYS hiding something."

"All hail the platypus who fears nothing but unicorns and keeps a two-year-old sandwich in a box."

"His name is STEVE." Perry retorted. "And for your information, he's two and three quarters."

"Fine, I'll stick some unicorns around. And maybe some pink ponies and baby blue kitty cats!"

"Why do you mock me?"

"Then I'll put up bats and cats. See ya." Darren went down the hall to talk to Devon the dog.

Perry approached the elevator to go back home. He REALLY hated parties.

"Oh, there you are, Perry." Phineas was carving a pumpkin. "Ferb and I made a giant pumpkin, but I don't know what happened to it."

Perry looked away from Phineas, recalling the day's previous events.

iPerry leapt into Doofenshmirtz's apartment and was instantly trapped in a fake spiderweb.

"Ah, Perry the platypus!" Doofenshmirtz uncovered his latest inator. "Allow me to introduce you to my latest creation: the pumpkininator!"

Perry struggled to break free from his trap.

"I bet you're wondering what it does. Well, it causes all the pumpkins in the tri-state area to evaporate!" Doofenshmirtz rubbed his hands together. "You see, back in Gimmelshtump, I was never allowed to carve my own Halloween pumpkins. So now I will take away everyone ELSE'S Halloween pumpkins! And then afterward, I'm going to watch 'El Matador De Amor'."

Perry narrowed his eyes.

"And now, watch helplessly as I destroy EVERY PUMPKIN IN THE TRI-STATE AREA!" Doofenshmirtz pushed a large button. The inator zapped a random area.

Perry wiggled around until he was able to stick a hand into one of his fur pockets. He grabbed hold of his emergency scissors and started cutting himself free.

"Yes! I am a genius!" Heinz shouted.

Perry cut the last bit of the web and leapt at the evil scientist.

"AAAAGGHH!" Doofenshmirtz tried to pull Perry off of his back, but Perry held on tightly. He started to punch him.

Doofenshmirtz's head bashed the self-destruct button on the pumpkininator, which promptly exploded.

"CURSE YOU, PERRY THE PLATYPUS!"/i

Perry felt bad about the boys' Halloween pumpkin. He would make it up to them… somehow.

Perry was sitting in his lair, staring at the floor, when his friend Poppy entered, closely followed by Palmer.

Perry watched Palmer cautiously. He'd forgotten that platypuses aged quicker than humans. Palmer was hardly a baby now, already walking on two legs.

"Good to see you again." He said quietly.

"Settle down!" Poppy joked. "No need to get overexcited." She gave him a hug. "Palmer, you remember your daddy, right?"

Palmer folded his arms. "Aren't you the guy who almost fell out of the plane?"

"He remembers." Perry said.

"I hate to spring this on you." Poppy apologized. "Animals are coming in to paint the garage, and I have some stuff I need to do… could you…"

"Watch him?"

"Yeah."

"Sure."

Poppy beamed. "Thanks so much. I'm sorry I can't stay. Be good, Palmer."

Palmer shrugged.

Poppy went back up the elevator. Perry stood up. "Haven't seen you in two weeks."

"Yeah. I know. Can I walk around?"

"Need me to guide you?"

"I know where everything is already." Palmer insisted. "I was here only two weeks ago."

"Right." Perry nodded. "My mistake. Go ahead."

Palmer went into the main room.

Perry sighed and sat back down. He hoped Palmer would behave himself.

From what Perry remembered, the kid was a troublemaker.
