She gets so furious, she decides it's time for her to declare a fight with him. She stomps over to Doof's place. She passes by Phineas and Ferb's house, where they're busy filming a green screen movie for their website. It's about a giant monkey who terrorizes a jungle. At Doof's place, Norm is busy making crunchy eggs when all of a sudden, there's a knock at the door. Katherine bursts in and declares a fight with Doofenshmirtz. Doof pops out and is ready for her. They're about ready to fight, when Norm offers eggs. Both Katherine and Doofenshmirtz pass. They begin fighting. Doofenshmirtz gives Katherine a big punch in the gut which he believes is the final blow. Then, it cuts to a silly song. After the silly song, it reveals if Doofenshmirtz was right. He's not. Katherine is alright, and gives Doofenshmirtz a piece of her mind. Katherine eventually beats enough crap out of him Doof gives her the white flag, but he's not done with her.
