Mom's in the House

When Phineas and Ferb can’t find Perry, they decide to create the Perrytronic 3000, a mechanical structure that can assume any form. Of course, being aware of the boys’ every move, Candace decides to take a different tactic on her busting approach by using a new technique that keeps Phineas and Ferb from finishing their Perry project. Meanwhile, Doofenshmirtz invents a Duplicator-Inator-2 so that he can duplicate his own head and make himself twice as smart.

Episode Summary
Phineas and Ferb are in the yard. Linda walks out and asks what they're going to do today, to which Phineas explains that they want to take Perry on a walk. Linda says that she's either going to make spaghetti and meatballs, or a spaghetti meatball, which is just spaghetti inside of a meatball. She heads to the store to get ingredients. Phineas asks Ferb where Perry is and it shows a quick image of different rooms of the house. He then decides to make a Perrytronic, which Ferb then finishes his sentence by pulling out a blueprint.

It shows Perry circling Doofenshmirtz's with bat like wings. Monogram explains the plan while Doofenshmirtz watches, completely freaked out by Perry. He then decides he's finished and Perry punches him, before getting stuck in a bird cage. Doofenshmirtz reveals his plan to give himself two heads, as "two heads are better than one".

Back at the Flynn-Fletchers', Phineas tells Isabella to seperate the eyes a little, as Perry's eyes are always out of focus. Inside Candace's room, she is yelling "Work! Work! Work!" and Stacy is creeped out. Candace explains to Stacy that it's her plan, called "Busy Bee Busting" or "B.B.Busting". Stacy isn't convinced, so leaves, disappointing Candace.
