Episode Summary
Phineas and Ferb are glad it's the next episode, because now they can finally build what they wanted to build. They're going to build a machine that makes you stronger. Ferb wants to be the test dummy. Phineas lets him. Then, he wonders where Perry is. Perry enters his lair through a giant gallon of protein powder. When Perry lands, powder lands on him. Monogram gives Perry his mission. He says Doof has been focusing a lot on human anatomy. He needs to go over and see what's up. Perry heads off. Meanwhile, Phineas and Ferb are getting to work. Isabella comes over and wonders what they're doing. Phineas says they're building a machine to make people more buff. Isabella starts to have another Phineas fantasy. Phineas asks is she's okay, and she says she's never been better. Phineas thinks it's time to give Ferb his new muscles. Isabella snaps out of her fantasy, realizing it was Ferb. Just then, Ferb becomes muscular. He likes it. But then, Maddie comes running in with bad news. Phineas wonders what's wrong. She points to Buford who's ready to pick a fight. Meanwhile, across town, Perry bursts into Doof's lair and is trapped in a snap. He is now in a net. Doof presents the Weaken-Inator. With it, he will prevent Roger from competing in the Danville 5K. Back in the backyard, Buford and Ferb are about to have a fight. People are gathered to watch. Phineas, Isabella, Baljeet, Irving, Mikayla, Kaitlin, and Olivia are all watching nervously. Ford, Caleb, Dylan, and Austin are all anticipating the showdown. It's very intense. Ferb gets inside the Beak suit and uses it against Buford. Buford doesn't know what to do now. Caleb says to use the toxic shark. Buford thinks that's a little extreme. Ferb continues to beat up Buford. Kaitlin thinks he's gonna have to surrender at some point. Meanwhile, Perry escapes his trap. He beats up Doof. It switches back between Buford and Ferb's fight and Doof and Perry's fight. They end up doing the same things. Just then, Perry blows up the Inator and it fires one last ray. It hits Ferb, who is now back to normal. Buford says he can't hurt Ferb anymore. They shake hands and Buford is glad ice cream didn't fall on his head this time.
