Summary: Janet summons a ghost, and it traps her, Bonnie, and Perry in a haunted house. Meanwhile, Heinz recalls the time he turned into a were-cow.

Halloween special! Remember when Doof turned himself into a 'were-cow?' Well, they never told us what happened after that. This episode contains what I think happened, as well as some other comedic stuff. If you haven't seen the PnF episode, "That's the Spirit," I suggest watching it before you read this.

That's the Spirit 2: The Second Spirit (Part One)

*Doofenshmirtz Building, Halloween Night*

The door bell rang, and Brooke carried over a bowl of candy and answered the door. A girl in a witch costume and a boy dressed as the giant floating baby head said happily, "Trick or treat!"

Brooke laughed. "I never get tired of hearing that."

She put a piece of candy into each of their bags, and they responded with a, "Thank you!" and walked away.

"Happy Halloween!" Brooke called and closed the door. She sat next to her husband on the couch and sat the bowl on the table.

"Ah, good ol' Hallow's Eve," Heinz said. "The mystery, the free candy from strangers. What's not to like?"

"Did you celebrate it in Drusselstein?" Brooke asked.

"Yeah, but it wasn't nearly as cool as the Halloween, here in America. In Drusselstein, all you get are rocks (It's the Great Pumpkin, Charlie Brown reference), but those rocks have a purpose. You see, the more rocks you had, the more popular you were in the town." He scowled. "Roger got all kinds of rocks. Big, small, oddly shaped. If they were rocks, Roger got them!"

Brooke quirked an eyebrow. "I thought you made peace with your brother early on in this fanfiction."

"I can still be jealous of him! As I was saying, Roger got lots of rocks, and what did I get? One! I got one rock! I wasn't even out rock-getting - that's the Drusselstein version of trick-or-treating. No, I was in front of the house, being a lawn gnome! All I got was a pity-rock from my neighbor, Kenny (Lawn Gnome Beach Party of Terror)! I-it wasn't even a rock! It was a pebble! It was a pity-pebble! Ugh."

Brooke had quickly become uncomfortable. "Okay... I don't know how respond to that..."

Heinz tapped his chin in thought. "You know what else Halloween reminds me of?"

"I'm afraid to ask."

"That time I inadvertently turned myself into a were-cow."

That got Brooke's attention. "Were-cow? Don't you mean werewolf?"

"No. I mean were-cow. Oh, that was crazy. You see, Brooke, it happened a few years ago, when I declared war on grass. The-the reasons aren't important. What's important is what I did to deal with my little hatred of grass."

*Street*

Phineas was dressed as Indiana Jones, Ferb was dressed as a pharmacist, and Perry was simply wearing his fedora, as they all headed from house to house.

"Halloween is awesome!" Phineas exclaimed. "The mystery, the free candy from strangers. Not to mention the fact that Perry can go as himself, without people suspecting that he's an actual platypus!"

"That is a nice change of pace," Perry agreed. His wrist-comm beeped, and they all stopped. Perry narrowed his eyes in annoyance. "Dang it. I'll catch up with you boys later."

The boys waved, and Phineas called, "Bye, Perry!"

To the their surprise, Perry jumped into Ferb's trick-or-treat bag. Ferb looked inside the bag, did not see a platypus in it, and shrugged.

Perry landed in his decorated lair, and Major Monogram, dressed as a vampire, appeared on the screen. "Happy Halloween, Agent P. It seems that Ms. Applebottom is trying to conjure up spirits." Perry stifled a laugh, prompting suspicion from his boss. "And, what is so funny about that?"

Slightly embarrassed at his outburst, Perry said, "I-it's just... Spirits? Those don't exist."

"Oh, don't they?"

"With all due respect, sir, ghosts are just myths. Like polite Frenchmen, or North Dakota."

"You don't believe in North Dakota?"

"If you had my clearance, you wouldn't either."

There was an awkward pause. "Just...stop Ms. Applebottom."

*Doofenshmirtz Building*

"So, what happened after you were chased through a haunted house by angry villagers?" Brooke asked. (Remember, that was where "That's the Spirit" left off.)

"Well, I managed to tire them out to the point that they went home," Heinz replied. "However, there was still the matter of changing me back into a human. I-I knew I would change back in the morning, but-but I would be a were-cow again at night. It wasn't like a werewolf, which only changes on the full moon. I-I actually changed every night. It was a living nightmare! No pun intended."

*Flashback*

"Oh, Perry the Platypus, thank heavens it's you," Heinz said in relief, when Perry landed on the balcony. It was day time, and Heinz couldn't have been more grateful for the sun. "We've got to do something. I've been a half-man, half-cow...thing for a week! If this goes on any longer, I'll be even more of an outcast, even more of a loner. I-I'll be shunned from civilized society! Norm, depressing dramatic music." A radio appeared on Norm's chest and played the requested tune. Heinz sunk to his knees, cupped his hands together, and dramatically told no one specific, "Please, no! It's not my fault! All I did was declare war on grass!" The platypus slapped him in the face, snapping him out of his melancholy. "Thanks. I needed that."

The radio on Norm's chest disappeared, as the robot walked up to them. "SIR, WHY NOT LOOK UP AN ANSWER ON THE INTERNET?"

Heinz narrowed his eyes. "Right. Why didn't I think of that? Oh, wait. Idid. There is absolutely nothing on the Internet about were-cows. Which is weird, 'cause everything else is on the Internet."

*End of Flashback*

*Applebottom Evil on Halloween*

Perry ran up to an ancient, decrepid building and hesitantly knocked on the door once...only to have the door cave in. He heard someone shriek, "EEEEEEEKKK! Ghost!"

Janet and her younger sister, Bonnie, were kneeling on the floor, and Bonnie was clutching her sister in fear. For Halloween, Janet replaced her usual purple V-neck tee with an orange one, and Bonnie had switched from a pink dress and sandals to a black three-quarter sleeved dress, black flats, and stockings the colors of candy corn. A lit candle sat in front of them.

Janet calmly patted her sister's back. "Relax, sis. It's just Agent P." She smiled at her nemesis. "You remember my sister."

Bonnie let go of her older sibling and waved at the platypus, still unnerved. "Hi, Agent P."

Perry nodded in greeting and walked up to them. "Hello, Bonnie. I haven't seen you in a while."

"I've been busy." Bonnie swallowed thickly, wondering why on earth she agreed to this. "A-are you gonna j-join us?"

An evil glint sparked in Janet's eye, and she told Perry mysteriously, "We are going to summon the spirits of the dead."

Perry chuckled. "Honestly, I can't believe you two believe in ghosts."

Janet deflated. "You mean, you don't?"

"If they existed, don't you think I would have seen a real one, by now?"

"Have you ever seen a one-eyed, one-horned, flying purple people eater?"

"...No...?"

"Then, what's to say ghosts don't exist?"

Bonnie stared pleadingly at Perry. "Please don't leave me alone with her." Janet glared at her. Bonnie put her hands up defensively. "I just want to know that someone sane is on the premises."

Janet blinked. "Fair enough. So, Agent P, ya wanna join us?"

Perry rolled his eyes and sighed. "Fine. But, only because Bonnie looks like she could really use a sane person, right now. Er, platypus."

Janet grinned wickedly. "Excellent." An evil laugh erupted from her mouth. Perry hesitantly knelt down beside Bonnie. "Everyone join hands." They did so, and Janet closed her eyes. Bonnie started shaking, but Perry remained deadpanned. "Spirits of the unliving, if you can hear me, please give us a sign." They waited.

Perry looked around. "Well, nothing happened. As I suspected. Can I go now?"

Suddenly, the candle went out, and the three of them shivered from the sudden chill in the air.

"They're here," Bonnie squeaked.

Perry rolled his eyes. "It's probably just a draft. These old houses are full of them."

Janet quirked an eyebrow. "How do you know what old houses are full of?"

"When you're a secret agent, you know about a lot of things that people don't generally care about." A gust of wind blew into the building. Perry stated matter-of-factly, "Okay, that can be easily explained." The broken door pulled itself back up, stopping the wind. They stared at it in fear, Perry swallowed thickly. "That is somewhat less explainable." The candle and floated. It spontaneously exploded, and Bonnie screamed. Perry shivered in fear and pointed to where the candle used to be. "And, that defies all logic and reason." He stood up. "Well, it's getting late. I-I should probably head home. Good luck with the ghost that's apparently real."

A cabinet moved in front of the door, and a demonic laugh filled the room. The three living beings huddled together in fright. Janet snarled at Perry, "Do you believe in ghosts now?"

"Yes!" Perry exclaimed. "Yes, I do!"

Bonnie bolted to her feet and flailed her arms, yelling, "Why are we just sitting here!?" She ran away, screaming.

"Bonnie, come back!" Janet called before chasing after her. "The ghost will eat you alive!"

Perry ran after her. "Hey! Don't just leave me here!"

*Doofenshmirtz Building*

"Then, what happened?" Brooke asked.

Heinz thought about it. "Hm... Well, night came, and we still couldn't find an answer to the whole were-cow debacle. I-I don't remember what happened after that. Mostly 'cause I don't have any recollection of being a cow-man-thing... Perry the Platypus would probably know. Maybe I'll call and ask him." He picked up the nearby phone and dialed Perry's number.

*Haunted House*

Perry walked alone the hallway, a flashlight in his hand. He jumped, as he felt a vibration in his hat. Relieved that it was only his cellphone - "How am I getting a signal in here?" - he grabbed it out of his hat and answered it, trying not to sound frightened. "Hello?"

Heinz voice came from the other end. "Hey, Perry the Platypus. It's me, Heinz. I was wondering if you could tell me how I stopped being a were-cow. I mentioned that little mishap to Brooke, but I can't seem to remember how it ended. After all, I-I was a were-cow at the time."

"Doc, that's gonna have to wait. I'm in a bit of pickle, here."

"What's wrong?"

"Well, long story short, I'm in this building, and there's a ghost, and the whole thing is insane. Doc? Are you still there?" He looked at his phone and scowled. "Great. Battery's dead. But, when Carl's babbling about how he got his first girlfriend: full charge." The flashlight flickered off. "Well, that happened."
