|“||From now on, I'm going to be a good guy!||”|
— Heinz Doofenshmirtz
Candace's plans to watch over Phineas and Ferb backfire when Dr. Doofenshmirtz's "Babe-inator" turns her brothers into babies. After having an epiphany, Dr. Doofenshmirtz shows up at the OWCA to give up his evil ways. Agent P has no choice but to show Dr. Doofenshmirtz the ropes of the trade, but things quickly sour between the two after Dr. Doofenshmirtz accidentally exposes the identity of a fellow animal agent.
Agent P heads to his lair and got surprised to see Dr. Doofenshmirtz on the screen. Major Monogram says that he has turned to the good side and written the "I give up" application and since he got raised by ocelots it supposedly makes him an animal, but tells Agent P he needs to supervise him. Doofenshmirtz explains that he quit evil after trying to use his "Babe-inator", which he plans to turn his brother and the people into babies, and failed; Making him think that he's not good at being evil, which made him decide to do good and Agent P gives him his own cubicle.
Later it got revealed that even though the Babe-inator wasn't plugged in, Norm plugs it back while cleaning up the lair. The Babe-inator activates and it then hits Phineas and Ferb, turning them into babies. Thinking that Phineas and Ferb caused this to happen, Candace tries to take a photo of the two, who have now been turned into babies, and sends it to Linda successfully. However, she simply thinks it is a baby photo of them. Candace then attempts to take a photo of them with a newspaper, but Phineas throws her phone in a fountain and Ferb tears apart the newspaper. She decides to use a stroller and take them to show her.
Doofenshmitz, meanwhile, is in his cubicle checking the computer and finds out that Newton the Gnu is Agent Silent G and he blogs it. He then goes on a coffee break with the other agents and ignores the screen that warns of a security breach and an agent captured.
Candace goes through the park and Phineas and Ferb start crying. They go to a store where Candace leaves them outside to get toys for them to quelch 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 gets caught by the cops.
Doofenshmirtz and Agent P got called to Monogram's office to hear that someone revealed Newton the Gnu's secret identity, and was caught by his nemesis, Dr. Diminutive. He ordered Doofenshmirtz and Agent P to head out to save him. They takes the hover-jet and Doofenshmirtz presses a button that fires a missile, which accidentally destroys Monogram's car.
Doofenshmirtz and Agent P make it to the apartment where the agent is being held where Doofenshmirtz attempts to kick down the door but gets his foot stuck. Dr. Diminutive appears, who has Agent Silent G captured and now he catches them too with his Photon 2000 particle bubble-"erator". Dr. Diminutive tells them that he quickly learned Newton the Gnu's identity when Doofenshmirtz put it in his blog. Candace chases the babies in a toy store and finally catches them.
Dr. Diminutive hangs them all off the edge of the apartment and drops them 40 stories down, but Agent P uses his grapple gun to catch the particle bubble-inator to trap Dr. Diminutive in a bubble and saves them by using it to create a bigger bubble, which they ride into and Doofenshmirtz taken them to safety and later crash into Monogram's office.
Candace arrives at the baby shower but the boys got taken by the Fireside Girls who are helping out at the event.
Back at the O.W.C.A, Monogram's office was getting repairs and Monogram with an arm cast and had to stay in a cubicle. Monogram congratulates Agent P for rescuing Agent Silent G and then fires Doofenshmirtz for many complaints in Human Resources.
Doofenshmirtz blames the duck agent and tells him he does so much damage for being good that tells him to returns to evil after believing he is better off that way. He then calls Norm to polish off his -Inators and leaves, which Norm starts off with the Babe-inator and it hits Linda and the Fireside Girls (except Holly and Adyson) thus turning them into babies while Candace is trying to explain to them that Phineas and Ferb got turned into babies. She breaks the Fourth wall that she hopes it wears off before the next episode.

I know what we're gonna do today!
He also cries along with baby Phineas.
Hey, where's Perry?
Candace: Okay you two, I'm in charge and I'm gonna lay down some ground rules!
Phineas: Okay, shoot!
Oh, there you are, Perry
Perry's entrance to his lair
He twists a board on the fence, turning it into a diving board. Then he dives into a baby pool, and the water floods into the lair, along with Perry.
Doofenshmirtz: Wow, my own cubicle. (Agent Kitty joins him and Perry) How nice! I'm gonna put a poster, right here, with a kitten that says, "Hang in there." (Doofenshmirtz turns and sees Agent Kitty; chuckles awkwardly) No offense. It's not like I think that's all you guys do, or anything. (Agent Kitty walks off) Oh, great, now he's going to Human Resources.
Candace: (After she puts baby Phineas and Ferb in a stroller) That's it, go right to sleep. You'll be busted in just a little bit.
Major Monogram: Enter. Agent P, we have a situation.
Doofenshmirtz: Is this about that grape joke? Who told on me? Was it the duck?!
Doofenshmirtz: I am loving this! We're all like partners, now! Like Jack and Jill, or Alice and Wonderland! And with a super-cool vehicle!
Major Monogram: Be careful out there. Washing my car. Don't scratch it.
Robber: Suckers! (laughs) Oh, my bike. (the police show up) Oh, good the cops are here! Maybe they can report this vandalism to--
Police: (in megaphone) PUT YOUR HANDS UP!
Major Monogram: It's humiliating! I'm stuck in this crummy, little cubicle while my office gets repaired! Anyway, Agent P, due to your quick action and decisive action, you were able to rescue Agent Silent G. Doofenshmirtz, you're fired.
Doofenshmirtz: Is it because I blew up your car?
Candace: Okay, I get it, lesson learned. Toddlers aren't easy. The irony is not lost in me! A little help here? This had better wear off before the next episode.

- Before Isabella was hit with the Babe-inator, she was wearing her Fireside outfit, but after she was hit, she switches to her regular pink outfit.
- Some of the Fireside Girls have their sashes on their right shoulders instead of their left before and after getting affected by the Babe-inator.
- During one part of "Here's Why It is Great to Be a Baby", Phineas, Ferb, and Candace were in their own house, despite being in the store before, for most of, and after the song. They also seem also to appear in Isabella's kitchen in one shot.
- Linda should've gotten a little suspicious when she saw the picture of Phineas and Ferb as babies because they didn't meet each other until they were at least 5 years old as seen in "Phineas and Ferb Get Busted!" and Phineas and Ferb The Movie: Across the 2nd Dimension.
- If Perry jumped through the hologram of Dr. Diminutive, Dr. Diminutive shouldn't have been able to open the door to them.
- Candace was eating health squares but they were cylinders.
- After Katie got affected from the Babe-inator, her party hat turns orange.
- When Carl is washing Monogram's car, a handicap spot marker was on the ground in the space above the car. When Doofenshmirtz blows up the car the handicap space marker is gone.
- After Candace decides that she is going to buy them toys, when she places Ferb back down, the seat belt in his seat automatically appears without Candace putting it on.
- When Candace took the photo of baby Phineas and Ferb, she should've included herself in the picture before sending it.
- It got mentioned that Doofenshmirtz were raised by ocelots again. ("The Chronicles of Meap", Phineas and Ferb The Movie: Across the 2nd Dimension, "Skiddley Whiffers").
- The Hard Way - The partnership between Doof & Perry copied from relationships between Nick Lang & John Moss in the movie.
- The Karate Kid - Monogram tells Carl washing his car will teach him karate, which is what Mr. Miyagi tells Daniel in this film.
- Sky High - The Babe-inator is just like the Pacifier in the movie, Sky High which they can both turn people into babies.
- Happy Hallow Park & Zoo - Danny the Dinosaur is nearly identical to the San Jose children's park/zoo mascot.
- Discover Card Commercial - The tune of the end of this episode's song is similar to the tune of the commercial.
- This is the 20th episode which Perry doesn't battle Doofenshmirtz. ("Get That Bigfoot Outa My Face!", "Put That Putter Away", "The Monster of Phineas-n-Ferbenstein", "Oil on Candace", "Unfair Science Fair Redux", "Tip of the Day", "Thaddeus and Thor", "Oh, There You Are, Perry", "Undercover Carl", "I Was a Middle Aged Robot", "Nerds of a Feather", "Split Personality", "Run Candace Run", "Candace Disconnected", "Skiddley Whiffers", "Bullseye!", "The Doonkelberry Imperative", "Meapless in Seattle")
- Dr. Diminutive has his own nemesis named Newton the Gnu a.k.a. Agent Silent G.
- First time Isabella and the Fireside Girls (except Holly and Adyson) were and became infants.
- Holly is the only Fireside Girl who did not appear.
- Candace breaks the fourth wall at the end.
- Major Monogram's car is a black sedan.
- Like Phineas, Dr. Doofenshmirtz also scratches his ear when lying/covering up a lie, being the third character who does something while covering up a lie (Phineas does in The Beak and Carl in Delivery of Destiny).
- During the end of the episode when all the agents were fixing the agency you can see that there are two pig agents. One is the regular one wearing a fedora and another one seen wearing a hardhat. This could mean that the agency might use more than one agent of the same species.
- It is never explained what happened to Phineas, Ferb, Linda, Isabella, and the Fireside Girls (except Adyson and Holly) at the end of this episode. Maybe the Babe-inator zapped them again, and they got turned back into their normal selves.
- Though the most plausible explanation is when Perry eventually returns home and sees what happened, since he knows what the Babe-inator is, he can easily go back to Doofenshmirtz and reverse it.
- It is also possible that it simply wore off.
- Fourth time the O.W.C.A. headquarters were seen. ("Traffic Cam Caper", Phineas and Ferb The Movie: Across the 2nd Dimension, "Delivery of Destiny")
- Second time Ferb was crying, the first being Phineas and Ferb The Movie: Across the 2nd Dimension.
- Fifth time Candace lost her cellphone. ("Greece Lightning", "Candace Disconnected", "Meatloaf Surprise", "Meapless in Seattle")
- Agent M appears again. ("Phineas and Ferb Musical Cliptastic Countdown")
- Fourth time Phineas was as a baby. ("Phineas and Ferb Get Busted!", "Oh, There You Are, Perry", "Phineas and Ferb Summer Belongs to You!")
- Third time a character goes to a baby shower, second time it was Linda. ("Attack of the 50 Foot Sister", "Tour de Ferb")
- Second time Doofenshmirtz "gets on the good side". ("Voyage to the Bottom of Buford")
- Phineas and Ferb get hit with one of Doofenshmirtz's Inator's again. ("Gaming the System", "Canderemy", "Phineas and Ferb Interrupted")
- Second time a character gets told washing something will teach them karate. ("Doof Dynasty")
- Second time someone got their foot stuck in a door. ("Chez Platypus")

- Second time Linda was seen as a baby. ("Mom's Birthday")
- Many agents of the O.W.C.A. appeared. ("Cheer Up Candace", "Phineas and Ferb Christmas Vacation!", Phineas and Ferb The Movie: Across the 2nd Dimension)
- Candace was eating "Health Squares" cereal at the start of the episode, the same kind of cereal Jeremy ate on his day to visit colleges. (Phineas and Ferb The Movie: Across the 2nd Dimension)
- Doofenshmirtz leaves his Babe-Inator unplugged. This is the exact opposite of what he does to his Shrink-Inator. ("Does This Duckbill Make Me Look Fat?", "Let's Take a Quiz")
- Fourth episode having the word "Doof" in its title, the others being "Hail Doofania!", "The Doof Side of the Moon" and "Doof Dynasty".
- This episode reveals that Dr. Diminutive builds -erators, like Doofenshmirtz's -inators and Rodney's -inizers.
- The joke that Doof tells during the coffee break is a reference to the "Duck Song."
