So if PETA's reading this, in my defense he was a guy before becoming a horse. Still don't own Phineas and Ferb. Thanks for reading!

Isabella POV:

Isabella's alarm clock blasted loudly as the sun rose across the horizon. In response, Isabella whacked the top of it while moaning to herself,

I would give anything to get back into that dream I was just having; me and horse Phineas were just about to get frisky!

She slowly got out of bed and got ready for the summer day waiting for her across the street.

Isabella happily trotted across the sidewalk toward the Flynn-Fletcher residence. She walked through the gate and was just about to say her catchphrase when Phineas galloped up to her, literally.

"Hey Isabella! Me and Ferb had an early start this morning, so with the extra time, we made a machine that can transform someone into any animal, real or not! I think you can tell already that I made myself a centaur!" Phineas neighed, again quite literally.

Issabella stared and said nothing. Phineas looked exactly how she had always imagined him. He stood tall (for once) with his normal upper torso on top, and a brown horse body on the bottom.

He's… perfect.

Phineas spoke again, "If you would look over behind the tree you can see that Ferb already turned into a dragon, Baljeet into a Gorilla, and the chicken running around over there is Buford."

Isabella continued to say nothing.

"So far the machine doesn't seem to have any unwanted side effects, so you're welcome to try it out!" Phineas said happily.

Isabella just stared at him some more.

"Um… Isabella are you ok?" The boy asked with a concerned look on his face.

"C...Can I…" Isabella finally said, "...ride you?"

"I don't see why not!" Phineas neighed, positioning himself so Isabella could get on.

Isabella quickly hopped on, and when she noticed there was nothing to strap herself onto, she simply latched herself onto Phineas' upper half.

"Alright here we go!" He shouted, as they blasted off into the neighborhood.

Isabella had never felt a feeling like this before. The wind going past her as they sped down the road made her feel alive. The girl was cheering as they continued to gain speed.

"Faster Phineas Faster!" She yelled.

As they continued to get faster and faster, Isabella had to hold on tighter and tighter to Phineas' upper torso. She noticed the blush coming off him as she got closer to him. Finally Phineas came to a stop and said while panting,

"Ok I think we should go meet up with the others again."

As much as Isabella ditdn't want this to end, she knew that the gang were probably waiting for them so they could start their next big project. As Phineas galloped slowly home, Isabella whispered into his ear,

"Phineas?"

"Yeah Isabella?"

"Can you be a horse more often?"

A little shorter than normal, but I hope this still turned out good! Review and let me know how to improve!
