When the Pokemon characters need to go home, they leave but realize they left Pikachu back at Danville, so they travel back. Meanwhile, Pikachu got lost in Perry's lair and was recruited by the OWCA so Pikachu can be fully trained to impress Ash. When the Pokemon characters come back, they find Pikachu when he is on a mission so Pikachu is taken away from them forever.

Perry feels bad for Pikachu, so tries to comfort him, but ends up staying with him in uniform for to long and the Phineas and Ferb characters see him. That forces Perry and Pikachu needing to go alone to a new family.

Meanwhile, Phineas, Ferb, Candace, Isabella, Ash, Misty, Max, and May go searching for them secretly. They find them and become secret friends.

After a few weeks, when they visit Pikachu and Perry secretly, but Major Monogram finds out and makes Perry get reloacted again, this time to an other dimension. Then when hope is almost lost, Ash finds a loophole in the rule and they can forget the adventures. They tell Major Monogram, and he uses the mind-change-inator to change them to thinking that the P&F characters and the Pokemon characters are friends and Perry and Pikachu's agency never existed.

After that, Pokemon characters and Phineas and Ferb characters just get along. They have their pets back and live HAPPILY EVER AFTER!
