Agent Doof

From now on, I'm going to be a good guy!

Doofenshmirtz thinks he isn't good at being evil, so he goes to the good side. However, Doofenshmirtz Babe-Inator hits Phineas and Ferb, turning them into babies and Candace has to take care of them.

Episode Summary
Mom is heading to a baby shower, and leaves Candace in charge. Agent P heads to his lair and sees Dr. Doofenshmirtz on the screen. Major Monogram says that he has turned to the good side, but Agent P needs to supervise him. Doof explains that he quit evil after trying to use his "Baby-inator", which turns people into babies, and failed. Norm is afterward shown still in the lair, and plugs it in, ignorant of what it does, and it then zaps Phineas and Ferb.

Candace tries to take a photo of the two, who have now been turned into babies, and sends it to Mom successfully, however, she simply thinks it is a baby photo of then. Candace then attempts to take a photo with them and a newspaper, but Phineas throws her phone in a fountain and Ferb tears apart the newspaper. She decides to use a stroller and takes them to show her mom. Doof is shown in his cubicle at the O.W.C.A. He finds out the identity of a secret agent and he blogs it, breaching security and getting said agent captured. He then goes on a coffee break with the other agents.

Candace goes through the park and P&F start crying. They go to a store where Candace leaves them outside to get toys for them to quench their sadness while a robber arrives on his motorcycle and breaks into the store. The babies then use the motorcycle and hook it up to the stroller and escape, while Candace chases them and catches them while the robber is caught by the cops. Doof and Agent P are called to Monogram's office to hear that someone (Doof, but he doesn't know that yet) revealed Agent Silent G's, Newton the Gnu, identity, and has been caught by his nemesis. They head out to save him.

Candace arrives at the baby shower but the boys are taken by the Fireside Girls who are helping out at the event. Doof and Agent P make it to the apartment where the agent is being held where Doof attempts to kick down the door but gets his foot stuck. Dr. Diminuitive appears, who has the agent captured and now he catches them too. He hangs them all off the edge of the apartment and drops them, but Agent P uses his grapple gun to hang onto a machine and saves them by using it to create a bubble, which they go into and are taken to safety. They later crash into Monogram's office, who then fires Doof who returns to evil after believing he is better off that way.

Doof returns to his lair and tells Norm to polish off his -Inators, which then starts off the Baby-inator and hits Linda and the Fireside Girls while Candace is trying to explain to them that Phineas and Ferb are babies. She says she hopes it wears off before the next episode, hence breaking the fourth wall.
