(FOXRADIO) Chapter Three: The April Fool's Day War:

Phineas wakes up to his brother laughing hysterically. "Why are you laughing, Ferb?"

Ferb could only point to the mirror. Phineas looks at the mirror, his mouth opens wide. His hair is pink. It is pink! He turns to Ferb.

"I guess I'm not the only one to strike at night. She's gonna get it. The prank war is so on."

Elsewhere, Isabella is getting ready to go over to the Flynn-Fletcher backyard. Isabella giggles to herself as she combs her hair, thinking about Phineas' pink hair she died last night. She opens her closet and opens her mouth wide. All of her clothes were in stripes. They were in orange and white stripes. By the look of it, they were Phineas' shirts. She blushes; now, she has to wear her crush's shirt. Phineas…

She grins and turns to Pinky. "The prank war is so on."

Later that morning…

"Hey Phin—"Isabella couldn't finish her sentence, she was too busy laughing at Phineas' hair. "Wow, I have to say; it looks better in the light."

Phineas turns around to look at Isabella, but he stops short. She is wearing his shirt, his shirt.

"Phineas?"

He continues to stare. He couldn't believe she actually wore it. The thing that made Phineas stare was the fact that she looks good in it.

"Um, Phineas…"

Phineas clears his throat and brings his eyes to hers. "You wore it."

She looks down at his shirt. "You took all my clothes."

Phineas rubs the back of his neck. "Right…"

"Okay…" She pauses. "So whatcha doin'?"

"Well…."

Later that afternoon…

"I'm going to get you, Nerd!"

"Somebody help me!"

"Ferb! Duck!"

Ferb ducks and the pie hit Isabella square in the face. She wipes the pie from her face. She clenches her fist. "You're so going to get it, Flynn."

Ferb steps away, and Isabella lunges at Phineas. Phineas yelps in surprise, and sprints away screaming; "Ferb, why did you move?"

"You really think I want to be in path of Isabella's wrath?"

Later that evening…

Isabella scrubs her face in the Flynn-Fletcher's bathroom, trying to get off as much pie as she can.

"Hey Isabella," Phineas says, leaning on the bathroom door's frame. "Wanna stay for dinner?"

She turns to him and smiles. "Sure,"

She takes the towel and starts to dry her face. Phineas stands and watches. She throws the towel in the dirty laundry.

"Hey, you missed a spot." Phineas says, stepping closer.

"Where?" She turns towards the mirror. "Oh." There was some pie right on her lips.

Phineas grabs another towel. "I got it." He carefully wipes it away.

"Thanks," She smiles.

He puts the towel down, without leaving her gaze. "You're welcome. You know, I never got to tell you; you look really good in my shirt."

She blushes. "Thanks, Phin."

Phineas smirks. "You know, I think there is another spot you missed."

He kisses her on the lips. She faintly tastes of pie…
