"I, Brobot" is the second half of the tenth episode of Phineas and Ferb.


Phineas and Ferb build robot versions of themselves, Phinedroids and Ferbots, to help out with their Big Ideas. Meanwhile, Dr. Doofenshmirtz regrets all the messages he left on his girlfriend's answering machine.


The boys are sitting under the tree in the backyard, going through the candidates for what awesome thing they will do today. Among the choices are a completely food-based water park, a tunnel to the center of the Earth, a chamber of invisibility, and a microscopic zoo that rests on the head of a pin. As the realization sinks in that they have a lot of blueprints, models, and schematics, a falling leaf prompts Phineas to comment that "summer doesn't last forever and we've got too many plans for just the two of us. We either need more days of summer or more of us." Ferb hands over his plans for a robot, and that gives Phineas an idea: make Phinedroids and Ferbots.

At this moment, Phineas notices Perry is missing. Perry is up on the roof of their house, pressing bricks on the chimney. The chimney opens up to reveal an elevator. During the trip down to his lair, it makes a stop and Santa Claus gets in. Perry gets off, revealing a sign that says "Chimmney Vator." Major Monogram begins the briefing, telling Agent P that Dr. Doofenshmirtz has made 57 phone calls in the past hour, but he doesn't know to whom or why. Agent P points back towards the elevator door, but Major Monogram says it's not to Santa. As Agent P leaves, Major Monogram tells Carl, who is off-screen, that this is why he doesn't like using the Chimmney Vator, besides the fact that Santa owed him a pony.

Back in the garage, the boys are finishing up the robot-building device. Phineas places pictures of them on the scanner. Within moments, the robots are done in the new version of the device. The one sitting in the background is deemed an "old dinosaur." As pairs of the Phinedroids and Ferbots march out of the new device, Phineas starts to welcome them. He notices that Ferb's bullhorn is not on, even though Ferb isn't saying anything. He continues and asks the robots to each take a blueprint and report to the backyard. Phineas asks Ferb to do the honors, which is to select "dance mode" on the remote control. The robots begin dancing and sing Phinedroids and Ferbots. The boys join in and soon, everyone is "busting chillin' moves with their robot poses."

Meanwhile, at Doofenshmirtz Evil Incorporated, Dr. Doofenshmirtz is scrunched up in a red chair, muttering "why won't she pick up?" Agent P lets himself in the room using a key that Dr. Doofenshmirtz has given him. Dr. Doofenshmirtz thanks him. "Much more civilized than crashing through my ceiling, don't you think? Yes." Dr. Doofenshmirtz then tries to persuade Agent P that he isn't up to anything, just dealing with a "relationship bump" with his new girlfriend. Agent P glances over to the computer, where there's a plan for a crane-mounted magnet. It will help him erase the messages he's left on her answering machine. Agent P gives him a disapproving look, so Dr. Doofenshmirtz activates a rope trap. "Too bad for you. Too bad you don't believe in love", he says. As he drives off in the crane, he yells, "Too bad!"

Meanwhile back at the house, Candace is on the phone with Stacy. She can't watch Stacy get her ears pierced because she is in charge while Linda is over at Zippy Pics. A Phinedroid walks by the window, carrying a ladder. At first, Candace doesn't think this is unusual, until a second Phinedroid walks by, carrying the back end of the same ladder. Candace goes to the backyard and is confronted by the sight of multiple Phineases and Ferbs. She concludes that her brothers are robots. "They're brobots!" She freaks out, runs through the house and climbs down the ladder into her Panic Room. Clutching Mr. Miggins, she calls her mom. "Phineas and Ferb, and Phineas and Ferb, and robots. Chamber of invisibility. Elephants." she squeaks.

Mom's heard this all before and tells Candace she'll see the robots after she gets home. Candace knows everything will be gone by that time. But as she talks to Mr. Miggins, she realizes that if she captures one she'll have proof. After donning protective gear, she sets out a can of oil as bait. A Ferbot takes a drink, and Candace catches it in a burlap bag. Candace dumps the bag in front of the house and then calls Stacy to let her know what she's done. She doesn't get very far because Stacy is crying. A few moments later, Stacy's mom comes on the phone so Candace pretends she didn't know anything about the ear piercing. Behind her, a garbage truck has picked up the burlap bag, followed by a Fred's Fertilizer truck dropping off a bag of fertilizer. Candace is thinking about "poor, mixed-up Stacy" and doesn't notice the change.

Back at Doofenshmirtz Evil Incorporated, Agent P pulls a can of Fancy Cheese Spray out of his hat. A mouse climbs down the rope and starts eating the cheese the Agent P sprayed on it.

Over in the backyard, Phineas and Ferb check on the robots' progress. The Chamber of Invisibility is completed. Phineas congratulates the Ferbot, and then notes he'd normally tell Ferb that. Next is the microscopic zoo. Phineas climbs up the ladder and peers through the eyepiece of the giant microscope. That's a success, too.

As Phineas looks at the tunnel to the center of the Earth, he begins to realize that it isn't as fun when others do their projects for them. At this moment a Phinedroid delivers a new plan to him. It's for the hovercraft lounge chair, which the Phinedroid has already completed and rides away on. This was the plan that the boys were going to do the following week. Phineas sees it's getting worse. The robots have run out of projects and are designing their own. Phineas asks, "Have we learned nothing from Mary Shelley's Frankenstein?" Then he notices the coffee stand. He pronounces the overpriced coffee stand as "so Nineties."

Just then, the coffee creates a new problem: the robots start going haywire. One can't sleep. When one falls down in front of him, Phineas decides to shut down the coffee stand. The Phinedroids and Ferbots don't like it. Phineas tries to execute the shutdown command but it doesn't work. The robots start closing in on the boys...

In a different part of Danville, Dr. Doofenshmirtz is driving the crane towards his girlfriend's house, singing along with the radio to "Gitchee Gitchee Goo." He's almost there, looking forward to erasing the embarrassing messages and leaving new ones. Just then he sees something in the road and stops the crane. Its Agent P. Dr. Doofenshmirtz realizes the mouse must have helped him escape. He warns Agent P to get out of the way or he'll drop the magnet on him. Agent P refuses to budge. After a couple of seconds, Dr. Doofenshmirtz releases the magnet. Just before the magnet lands on Agent P, Santa swoops by in his sleigh and catches the magnet on the sleigh's runners. Dr. Doofenshmirtz exclaims that it doesn't make sense because it's the middle of July. Santa replies that he's on a summer run. As Santa flies off, Dr. Doofenshmirtz says, "bah, humbug."

In the backyard, things are looking grim. Phineas laments that their creations have turned on them and says "if only there was a device that could stop them." Ferb pulls out the remote control and Phineas says he was just messing with Ferb. Phineas presses the dance button. The robots begin dancing again and singing the second part of Phinedroids and Ferbots. On the front sidewalk, Candace proclaims, "Eighties music is so 2002."

Mom arrives and wants to show Candace the photos, but Candace is in a hurry to show her what she caught. She dumps the bag in front of her mom and opens it. Linda Flynn-Fletcher peers in and says, "That's a very nice bag of manure, Candace." Candace looks at it and shrieks, causing her to drop the pictures. Suddenly Candace hears some voices. Candace runs to the backyard. The robots are still there, so she tries to get her mom to see them. Neither of them sees Santa flying overhead. As he flies over the backyard, the magnet lifts the robots out of the yard. Candace says that even though she's done this nineteen other times, she's confident that there are robots. Mom agrees that there are Phineas and Ferb robots in the backyard, which is just the boys, still dancing like robots.

A few minutes later, Mom wants to show off the pictures again. A picture of Candace slips out of her hands and floats into the garage, landing on the scanner. The robot-building device makes a robot of her image. Candace freaks out again and she yells "It's a Candroid!" running in circles around her mom and the boys. She runs back into the panic room. The Candroid is already there, clutching Mr. Miggins. Candace reclaims Mr. Miggins from the Candroid telling her to give it back.




  • Although the Phinedroids and Ferbots were removed by Santa Claus, it was never shown what happened to the remaining completed projects, therefore, they should have been seen by Linda.
  • When Santa says "Ho ho ho, hold that elevator!" his mouth doesn't move at all.
  • When Mom says "Who wants to see pictures?" her mouth doesn't move at all.
  • The number of brobots shown varies in each scene, though six Phinedroids and six Ferbots is the most commonly-seen amount.
    • At the time they were created, seven pairs of Phinedroids and Ferbots emerge from the robot-building device.
    • When Phineas shuts down the coffee stand, 10 Ferbots can be seen advancing on the boys, with enough spacing in the semi-circle for an additional 4 to 6 Ferbots off-screen.
    • When the boys activate "dance mode" a second time, one Ferbot is missing from the circle, which would be the Ferbot that Candace captured.
    • At the end, Santa flies over the backyard with the giant magnet, pulling up six Phinedroids and eight Ferbots.
  • "Chimmney-Vator" is spelled wrong, as it should be spelled "Chimney-Vator".
  • Candace's phone worked perfectly in the panic room under the basement, where she should have gotten either minimal or no reception at all.
  • The live video feed from inside the Chamber of Invisibility is from a totally different angle than the video camera shown on the frame of the chamber.
  • Even though the robots disappeared, the robot making machine doesn't; therefore Linda should've seen it.


  • The name of the title is a parody of the Isaac Asimov novel I, Robot and the 2004 film based on it.
  • The music played as the leaf drops in the beginning when Phineas realizes summer doesn't last forever is "Morning Mood" by Edvard Grieg.
  • This episode contains the largest number of plans (8) in a single episode:
    1. Phinedroids and Ferbots
    2. Second-generation robot-building device
    3. Microscopic Zoo
    4. Chamber of Invisibility
    5. Tunnel to the center of the Earth
    6. Hovercraft lounge chair
    7. First-generation robot-building device (appears to have been completed prior to this episode)
    8. A completely food-based water park (discussed but not built)
  • Dr. Doofenshmirtz sings along with "Gitchee Gitchee Goo" while driving his crane. Also, when Perry is going down in the Chimmneyvator, it is heard as elevator music.
  • Agent P keeps the key to Dr. Doofenshmirtz's living quarters inside a pocket in his fur. This was given to him by Dr. Doofenshmirtz to cut back on damage to the building, evidence of the growing relationship between Agent P and Dr. Doofenshmirtz.
  • When the robots run out of plans that the boys gave them and started creating their own, a Ferbot is seen designing a rollercoaster. It is the same design that Ferb came up with in the episode "Rollercoaster".
  • Candace tells her mother, "I know I've done this nineteen other times" when attempting to show her mother what the boys are doing. Since this is the 19th episode produced, that would make training monkeys to juggle bicycles the first plan Candace tried to bust her brothers for, which is mentioned in "Rollercoaster".
