Hey Cookinators, IrresistibleCookie here.

This is chapter 25 and was requested by a guest – Phinabella, Gender Change, Romance. This one's also gonna be good! :D Heinz makes a cameo!

Let's go! Don't forget to R/R/Request!

I don't own P&F.

Heinz had done it. He had created the Genderswap-inator. It took quite a while to make without alerting the OWCA having any disruptions by Perry. He had managed to keep it a secret somehow. And now he would finally blast...where ever he should...it was probably at Roger...

He aimed it towards his chosen target; he didn't realize Roger was standing in front of a wall of mirrors. He fired the laser...and missed. It hit the mirror. Heinz stepped back.

"Oops! I wonder where that's going?" he wondered, chuckling slightly. After all, he was evil.

Phineas, Ferb and Isabella were planning the day's activity, when the laser hit Phineas and Isabella.

"What was that?" Phineas asked, noticing a sudden change of voice. His assumptions were correct.

"Phineas, why do you have my voice?" Isabella asked in Phineas' voice.

They screamed loudly and looked over at Ferb, who was covering his mouth in shock.

"Oh, my, lord..." he managed to get out.

(A/N: I'll refer to Phineas and Isabella in apostrophes.)

"Don't worry! We'll get through this!" 'Phineas' exclaimed. "Right, Isabella?"

"Uhh...sure...right?" 'Isabella' faked a smile.

"Let's get to work on the Gender Switchmaroo 9001*!" he exclaimed.

Isabella knew this would bring them closer together, them being Phineas and her. Maybe a like-like relationship could start, who knows.

I'll make this chapter into a full story if your review says so! 5 reviews say yes. Review up!

*- DBZ fans will understand.

Hope you enjoyed! R/R/Request/Request for a full story to this.

My name is IrresistibleCookie (even though I'm not what the username seems) and I'll see you all in the next chapter! Munching out since 2014.
