I don't own anything except the plot!

"Boys, bring down your bags! You're sister is going to be here soon." Linda called up to her sons from the bottom of the stairs. She stood and listened to her sons' feet scamper across the floor as they chased each other to the stairs.

Phineas reached there first and pumped his fist in the air and cheered. "I win!" But he was stopped short when Ferb came charging into him and knocking them both down onto the floor. Their duffle bags tumbled down the stairs, but Phineas and Ferb continued to laugh on the floor.

Linda groaned and picked up the two bags once they reached the ground, "Come on you two, it's raining and I don't wait Candace to have to come in and get you two."

Phineas jumped to his feet and slid down the banister and Ferb followed. Ferb flew off the banister and tumbled to the ground knocking Phineas off his feet again. Phineas yelped and fell in front of the door. He smiled and stood up and grabbed his bag from his mom.

Linda looked over at Phineas and asked, "Do you have everything you need?"

"Yep"

Linda started to count the items off with her fingers, "Toothbrush, clothes, pajamas, under-"

"I have everything, Mom, trust me!" Phineas quickly said stopping his mother from what was coming next.

Ferb picked himself up with his elbows and chuckled at his brother's expression. Phineas looked at Ferb and threw his pillow at him. When the pillow hit Ferb square in the face he fell to the ground with an 'oof'. Phineas laughed at his brother, but stopped when his mother cleared her throat.

"Phineas don't laugh at your brother and Ferb get off the ground. Candace will be here soon and I can't keep your father waiting at the airport. I already told you two, your father and I will be away for the week and Candace is watching you two. Don't give her trouble and cause her to frantically call me." Linda warned them as Ferb stood up and gathered his stuff.

Ferb nodded his head and Phineas said, "Of course Mom."

"Candace is here." Ferb announced as he watched her car pull up in the rain.

Linda nodded her head and bent over to place a kiss on Phineas and Ferb's cheeks before the two boys left. Linda waved to her daughter from the doorway. Candace waved back before looking at her brothers and signaling them to hurry up.

Phineas and Ferb raced each other to the car. Phineas almost slipped, but in the end he won by an inch. He smiled and threw open the car door and hopped in.

"Hurry up! Don't let the rain in!" Candace yelled to the backseat just as Ferb shut the door.

Candace impatiently waited for Phineas and Ferb to buckle their seatbelts before she drove off.

"Candace," Phineas called from the backseat.

"Yes?" She answered not taking her eyes off the road in front of her.

"Me and Ferb couldn't find Perry, but he'll show up later, is that okay?" Phineas asked.

Candace groaned, "Why does he have to stay in my house?"

"He loves you too, Candace." Ferb said.

Candace rolled her eyes and sighed, "Fine, but he stays in your room.'

Ferb gave her a thumbs-up and Phineas nodded, "Sure thing, Candace. By the way, you did get our soda, right?"

Candace nodded her head as she turned the corner, "Cherry and Root Beer."

"Thanks!" Phineas said and Ferb smiled and nodded his head in appreciation.

"No problem, guys." Candace smiled at her brothers.

In a few moments they arrived at Candace and Jeremy's house. By then it was now thundering and lightening, "Guys, get in the house quickly please. We don't need to call Mom because one of got burned to ashes."

Ferb rolled his eyes and Phineas chuckled and said, "We won't want that."

Candace narrowed her eyes at her brothers before telling them to get out. They laughed and hopped out of the car and walked quickly to the front door. They carefully made their way over so they didn't slip in any puddles.

Ferb used his toolbox to cover the rain from hitting him. Phineas saw this and noted, "How come you get the toolbox?" He clearly wanted something to protect him too.

Ferb smiled moved the box half off his head and half on. Phineas also smiled and dashed under the box also. It didn't do much, but it did something. The two boys adjusted themselves and turned around to see where Candace was, she was trudging through the rain holding the boys' duffle bags.

She groaned when she reached them, "You know you two are the men, you can lift the heavy stuff!" desperately trying to keep a hold of the bags. "What do you keep in these things?"

"All of the parts we may need for a future project this week!" Phineas said.

Candace rolled her eyes said, "well, come and carry 'em!" They nodded their heads and went to get them from her when their eyes caught a glimpse of something hopping out of the car.

Phineas and Ferb smiled widely and said at the same time, "Perry!" They dropped the duffle bags and dashed to the monotreme.

"Hey, boy!" Phineas called as they stopped in front of their pet platypus.

"Krrrr"

"We missed you too!" Phineas said petting his fur.

Ferb held up the toolbox above their heads and turned around to walk back towards the door. Phineas grabbed Ferb's hand and started to pull him to Candace so the two boys could pick the bags up first.

They were a couple of feet in front of Candace and Perry was a foot or two behind when lightening struck the toolbox in Ferb's hand. The shock transferred from the toolbox into Ferb and then through Ferb's hand into Phineas'. The boys yelped and fell to the ground.

Perry's eyes widened in shock from what he just saw and he couldn't move he felt paralyzed.

He watched in terror as the boys stand on the ground and didn't move at all. He could feel his stomach clenching as he started to expect the worst. Death.

Candace's eyes widened in horror when she watched her brothers fall. She gulped nervously and looked down at Perry. She could see a bit of worry in his usual unfocused eyes, but she didn't have any suspicion because in two seconds she was at her brothers' side.

She felt the hot tears burn and make it hard for her to see clearly. She tried to hold back her sobs as she shook Phineas' shoulders and then Ferb's. She bit her lip as she looked helplessly down at Phineas and Ferb. She anxiously looked up at her front door and called her husband's name-loud. "JEREMY!"

A few seconds later, Jeremy came running out the door faster then he ever ran before. "What's th-" He started, but stopped when he saw his brother-in-laws on the ground. He looked over at his wife and saw tears in her eyes as she held her jacket over her brothers so they didn't get as wet.

He quickly joined her side and kneeled and picked up Phineas. Candace watched her husband's actions and picked up Ferb. They made their way over to the front door and Perry slowly trailed behind.

Ferb's POV

I groaned and opened up my eyes and looked at my strange surroundings. I grabbed my head from the massive headache I have. It was most defiantly from the fact that I had just been electrocuted by a lightening bolt. I slowly picked my head up when I heard, "Phineas, you're awake!"

I frowned and looked in front of me. Candace was smiling as she sat on a folding chair besides the couch. Her eyes were looked sleepless and she looked exhausted. I turned my head slowly to the side and saw someone beneath the blanket on the other side of me. I guessed it was Phineas. That confused me; why did Candace say Phineas was awake if he's still sleeping. I rolled my eyes, she's probably worn out.

I looked at the time and read 3:56. The window was dark so that meant it was probably A.M. I sighed and turned back at Candace. She no longer had her bright smile; instead it was replaced by a small frown.

I gave her a questioning look and she said, "Are you feeling okay?"

I shrugged shoulders and in a hoarse voice replied, "I've been better." My voice was strange, but it probably sounded that way because my ears are probably messed up from the shock.

Candace's frown grew bigger and she crossed her arms, "Why are you so quiet?"

I arched my eyebrow, "What do you mean?"

"You're Phineas. The most energetic boy I know and you think that you don't think that you're quiet right how?" She half screeched.

I didn't answer my sister because she lost me at Phineas. I looked deep into her eyes and saw that she wasn't kidding. I looked down in my lap and pulled up my blanket revealing an orange striped shirt and blue jeans- Phineas' clothes. My eyes widened and I quickly kicked the figure in front of me until I heard him groan.

"Phineas don't kick Ferb! He's in just as much pain as you are!" Candace scolded me.

I just ignored her though and watched as my brother slowly sat up, "What do you want, Ferb?" Phineas said in irritation.

I gasped when I saw his face, well technically my face. It took him a second to process this, but once he did, he too gasped in shock. "F-Ferb?" He stuttered. "W-What happened?"

I shrugged my shoulders and shook my head.

"Ha hah, very funny!" Candace said sarcastically as she rolled her eyes. "Now cut it out before I call Mom."

"Cut what out, Candace?" I heard my voice, but it was really Phineas who asked.

"Don't play dumb, Ferb! You two think you can try and trick me to believe that you're Phineas and he's Ferb?"

"But, we are!"

Candace rolled her eyes and crossed her arms, "Yeah right, whatever."

"He's not kidding." I added.

"Phineas, I know how hard it is for you to be so quiet, so you can stop now." Candace said.

I looked over at Phineas and we exchanged uneasy glances. Candace must have noticed this because soon her smile disappeared and she became worried. She looked over at me and pointed, "Ferb…" She looked over at Phineas and pointed, "Phineas…"

We both slowly nodded our heads and Candace slowly covered her mouth with her hands, "Oh my gosh…"

Phineas looked over at me at said, "So I'm you…and you're me…?"

I nodded my head and watched as he smiled brighter than day itself and punched the air, "Awesome!"

Me and Candace looked at each other before rolling our eyes. Only Phineas would cheer at this.

Okay so next chapter Phineas will explain why he thinks this is so cool. This story includes Phinbella and Ferbnessa. They're not couples yet, that's a main part in this story; them becoming couples.

R&R plz?
