The Best Summer Ever! (Ferb x Oc)

Thaddeus and Thor

"Alright, Candace. I'm off to the grocery store. You're in charge." Linda told her daughter as grabbed her purse.

Candace looked up from her phone. "Whoa, whoa, wait, wait, wait. By 'in charge' does that mean I'm in control of everything around here while you're gone."

"Yes."

"Including Phineas and Ferb? I'm the complete overlord of them?"

Linda's eyes narrowed. "Suddenly, I'm a little scared. But technically, yes."

"So, like, in a court of law, any-"

"Candace, I'll be back later."

Candace grinned when her mom left. "Excellent. Oh, boys?" She went outside to the backyard where her brothers were sat in the grass. "Hear ye, hear ye. Mom has left me in charge, so I hearby demand that you do nothing crazy today. No building any whoosy-whatsits, or goozy-mahookas. In other words, don't be the world's most annoying brothers for one afternoon, okay?"

"You're brothers are annoying you too?" Said teen girl with curly brown hair on the other side of the fence. She opened the gate and walked into the Flynn-Fletcher yard. "Hi, I'm Mandy. And me and my world's most annoying brothers are visiting our aunt next door for the weekend."

Candace walked over to her. "Oh, you're Mrs. Weever's niece. You have annoying brothers?"

"Oh. My. Gosh. My brother, Thaddeus and Thor, are constantly building the most annoying contraptions on Earth. Soapbox cars with lawn mower engines, tire swings that launch over the roof, a mini shopping center for the cat."

Candace grinned. "Finally. Someone who relates. Listen to how annoying Phineas and Ferb are. They have this friend, Piper, who comes over everyday to help them and-"

While the two teens talked and bonded about annoying siblings, Mandy's brothers walked into the yard and strolled right on over to Phineas and Ferb.

The boy with curly ginger hair snapped his fingers. "Gum me." His blonde brother handed him some gum which he ate and smirked at the Flynn-Fletcher boys. "S'up,, chumps. Thaddeus, Thor." He introduced himself and his brother. "Overheard you two like to build stuff. Where we come from, we're known as the best. Jealous?"

"No. No I'm not." Phineas said.

"Well, you should be. Today, we're building the most awesome fort ever. What so you think of that, suckers?"

Phineas just smiled. "Cool. Good luck!"

Thaddeus frowned and walked away with his brother.

Phineas turned to Ferb and snapped his fingers. "Gum me."

Ferb rolled his eyes. "Puh-lease."

"Hey, where's Perry?"

Thaddeus had just reached the gate when he heard a new voice appear behind him. Glancing back, he froze at the sight of pretty white hair and pale red eyes.

"Hi, boys!" Piper called out as she ran over to them.

Phineas and Ferb lit up at the sight of her and waved back.

"Hey, Piper!" Phineas greeted back. "Candace told us not to do anything today, so how about we just go in and watch a movie?"

Piper shrugged. "Sure, what movie?"

"Don't know yet." Phineas and Ferb stood up and the trio went inside the house.

Thaddeus blinked and spun back around, walking right past his brother who was staring at him.
