Premise.
Phineas Flynn and his stepbrother Ferb Fletcher are two children who spend their summer vacation inventing new machines and/or building large wikt:contraptions so that they and their friends can have fun. Phineas’s sister Candace Flynn thinks that their mother would be angry with Phineas and Ferb if she saw the things they build so 
Candace spends each day trying to show her what Phineas and Ferb created to get her to punish them (or as Candace puts it to “bust” them.) But Phineas and Ferb’s pet platypus Perry is actually a spy secretly working for a group called OWCA (Organization Without a Cool Acronym) known as Perry the Platypus or Agent P who spends every day fighting the evil Dr. Doofenshmirtz. And every day Perry’s battle with Doofenshmirtz leads to him accidentally destroying whatever Phineas and Ferb built just before Candace shows it to her mother Linda so Linda sees nothing and doesn’t believe Candace who ends up looking crazy.
