A/N

This was in my head all day yesterday and begging to be written, especially hearing about the PnF Halloween eps, and imagined Doofy being a cute little werepus, but he just eats candy and very adventorus but causes no harm to others.

He gets bitten by Perry's cousin, Alexis who's one too but Perry doesn't know but at first is scared of his frenemy but loves him no matter what.

This is a cute story but think this'll be fun.

I know Inyunaruto365 loves it.

I'm debating whther or not if Agent L should be in it.

It was mid October, as Perry was going to Danville International Airport, as he was picking up his cousin Alexis as she was visiting from Sydney but he was excited having a member of his birth family here in Danville.

i hope that nothing interferes with her visit, like missions, but Monogram but he'd understand about that, as I never get to see my family.

Phineas and Ferb would be excited seeing her.

Perry had no clue his cousin was very special but not dangerous to humans, but had a massive sweet tooth.

He then heard that the flight from Sydney was coming in but was anxious

He then headed to the gate but saw Alexis there, eating Reece's peanut butter cups, but she looked shy making Perry curious but he hugged her, making her smile.

"Hey there, I'm Alexis." she said softly.

He knew she would be staying in Danville for a while, but Perry wondered why.

"I don't have a lot of friends back home." she said.

Perry sighed, getting into the hovercar, but saw her eyes widen seeing Halloween decorations, knowing Halloween was an aesome time.

Especially for her, fingering her pumpkin necklace.

"We're going to a friend's house." he told her.

They then landed at Doofy's.

But he saw her get excited, as Doof had a bag of peanut butter cups in his hand, but wasn't in the mood to share, but he then felt his hand in agony, but Perry was stunned, seeing this as there was a mark.

"Doofy, you okay?" Perry asked him.

"I'll be fine, Perry.

I'm gonna tend to the bite." he replied.

The teal furred male was stunned, seeing his cousin had done that to his friend but she wouldn't tell him why.

"You better not hurt my boys, Alex." he told her.

"I won't, Perry.

But there's something I need to tell you about your friend." she said.

But Perry was entering his lair, but told Alexis to tell the boys and also about herself.

\Wow, you're a werepus, Alex?

That's so cool" Phineas told the female werepus.

It was now evening, and the full moon had came out, meaning Alexis had became her werepus form, which was black shaggy fur, but was stronger and her senses were stronger, but Phineas saw her teeth were rotten, probably from eating candy a lot.

"Wow, you eat candy but don't harm people or animals?" he said.

Alex nodded, as ahe was eating chocolate cake, after dunking her face in the frosting, but Perry chuckled, seeing that as his cousin was cute and not a threat as she was helping the boys with their plans for the night, as it was Halloween after all, but Candace had gone out to hang with friends at a party.

He had an idea, as he could go trick or treating with them, as Alex was jumping up and down.

"Okay, let's do it." Phineas told them.

They then left the house.

But Doof was running around in his werepus form, with a sack full of candy he'd hijacked from houses but he was hungry since his frenemy's cousin had bitten him, but had looked up the bite online on an Austrlian folklore site, but he smirked evilly, knowing Perry would freak, but heard voices, as he saw his frenemy's owners with him and another werepus, but was hungry, running over and taking the pumpkin full of candy, but Perry was angry, going after him but Alex stopped him.

"Here, take some of mine.

I know how you feel." she told him.

Perry was looking at this werepus, but he looked familiar, but had Doofy's dark blue eyes, but shook that thought off, but he saw him run off but hadn't heard him talk or chatter, but Alex knew some of them didn't speak, as they were shy.

"Let's take it back to that house, Perry.

You can find him later." she told him.

Perry saw fear in that werepus's eyes as they left, but a thought entered his mind.

After the boys had gone to bed, and saw Alexis in the living room watching Ducky Momo, making him smile, but she had a feeling that he wanted to see if Doof was okay.

"I'm coming with you, Perry." she told him.

He then followed her, as he was telling her where to go but they entered seeing Platyborg holding that strange werepus by his neck, but Alexis made him drop him.

"Perry, help me!" it said as Perry gasped.

D-Doofy?" he said leaving.

Doof looked sad, as he felt tears welling but fell, as Alex saw him eating almond brittle, but would talk to her cousin for him, but Platyborg flew off.

He then relaxed, as she hugged him.

She knew her cousin would understand.
