Ok guys, here's the disclaimer, but it will change a little bit throughout the story;) I DO NOT OWN PHINEAS AND FERB. ANY CHARACTER THAT DOES NOT SEEM FAMILIAR IS PROBABLY MINE at least for this chapter

Perry's POV

14 year old Perry the platypus woke up on Phineas' bed to a hand poking him. As he inwardly groaned and turned around, he realized that Phineas and Ferb were already out of their bedroom. It was their older sister Candace who was poking him. That's new, Perry thought. Usually she doesn't want anything to do with me.

"Hey, Perry. Listen, we all just remembered some big events, so can you come into the backyard?" the teenager asked, emphasizing the big.

Perry nodded and walked out of the house on four feet. I wonder what they remembered, he thought, realizing his heart was beating quickly.

"You can walk on two feet, Perry," Phineas said. When Perry gave him a questioning look, Phineas explained. "All of us remember that second dimension day, and that you and Lydia are secret agents."

Perry looked over at the Flynn-Fletcher's adopted human daughter and partner in...whatever the opposite of crime is, Lydia. "I swear, when Major Monogram finds out they remember that day, I will personally punch him until he says it's okay for us to live with them without them losing their memory," Lydia promised, although it sounded like she was also threatening the major of her's and Perry's agency, O.W.C.A.

Perry nodded again, this time from excitement. When Lydia says something like that, she will follow through, so that meant that Perry didn't have to hide anymore. Perry stood up and put on his fedora, not hesitating at all. "And maybe I'll be able to convince Major Monogram to let you be part-time agents," Lydia added, smirking.

"Yes!" Buford, who was in the backyard along with Baljeet, Isabella, and Stacy, punched his fist in the air. "I might get to beat up bad guys!"

After Major Monogram agreed to everything Lydia wanted, Perry went home, happy that he didn't have to hide from his family anymore.

AWWWWW, SO CUTE! You rule, Perry:D :D :D :D :D

The next chapters will be longer, don't worry ;)

This prologue doesn't have much connection with the rest of the story, it just explains that for the rest of the story Phineas and friends know Perry is an agent, and it shows that Lydia will be in the story a little bit :P :P
