A/N

This was an idea my sister came up with last night when we were talking about Phineas and Ferb stuff and she said about if Perry joined Doof's side and I liked the idea so much, I wanted to write it.

Perry gets fired by Monobrow because he and Doofy want to be friends and he is angry.

Upset, Perry runs away to DEI and Doofy wants to help him but he wants their friendship to stay alive.

I'm still working on A Son He's Always Wanted.

It was a typical day in Danville and a certain turquise furred male had snuck away from the host family but was secretly going to DEI to be with Doof and knew that Monogram hated when he did that as Perry and Doof were supposed to be enemies but he and Carl had been keeping tabs on Perry but sighed knowing for years, Doof and Perry had been enemies but were unaware that they were frenemies and secret best friends but hoped that they wouldn't have to do the unthinable.

"Are you sure you want to do this sir?" Carl asked.

"Yes, Yes I have to.

Doof and Agent P can't be friends." Monogram told him.

He hoped that it wouldn't have to come to that.

Agent E then followed Perry to where he was going...

Doof was getting ready for a day at the beach as it was another frenemy kind of day which he liked but couldn't admit it to himself or the other members of Love Muffin but he had made a picnic but smiled hearing the door slam knowing who it was.

"Hey Perry.

I'm just getting ready.

Monobrow isn't onto us, right?" he said.

"No, No he's not." Perry replied.

Doof smiled at the turquise furred male as they were good friends and nothing would change this but didn't know Agent E was watching them and letting Monogram see knowing his boss wouldn't be happy.

He hoped Perry knew what he was doing.

Doof smiled as he and Perry were at the beach picking out a good spot as they had surfboards with them as Perry was going to teach him how to surf as he was an natural at already because he was semi-aquatic but Doof was a little nervous and understood.

"Don't worry Doofy.

I'll be right beside you.

It's gonna rock." Perry told him.

"Okay Perry.

I'll try." he said as they went into the ocean.

They were having a good time and just enjoying each other's company.

Later they were lying on the sand relaxing and wearing shades but suddenly they saw a shadow blocking their sun.

Perry shivered in fear seeing it was Monogram.

"What're you doing here Monobrow?" Doofy asked.

"Arresting Agent P for treason." he answered.

"Y-You can't do this to him!" Doof protested.

But Monogram didn't answer as he left but Perry gave Doofy a sad look as he left but Doof felt angry at Francis as he didn't care about feelings or how Perry felt about this but hoped he'd be okay as he packed up and left the beach.
