"Brobot" is the first segment of the 3rd episode in The Adventures of Jimmy Neutron: Boy Genius from the first season.


The episode opens with Jimmy attempting to find a friend to help him test his new invention. Since both Carl and Sheen are busy, he has no one to help him or to hang out with. He then sees Butch in the park with his little brother, having fun. Jimmy then begins to think that a little brother is exactly what he needs.

Later, Judy and Hugh of his thoughts using a side show presentation. He then requests a little brother. His mother is shocked and flustered, as is Hugh. They then try to explain that it is more difficult to give Jimmy a little brother than he thinks. Jimmy tries to debate that them having a son is simple, but Hugh interrupts him and offers his family pie.

Jimmy is then shown in his lab, saying that he will have to take matters into his own hands. First, the clock is ticking. Next, Jimmy fires an orange hat. Then, a screwdriver turns his shirt. Finally, Jimmy presses a red button, because his parents do not comply. He then proceeds to build a small robot in the darkness of his lab. He activates the robot by holding it up to the top of his lab until the thunder from the thunderstorm that went on outside at the time hit the robot. He then begins to talk about his new creation, saying he is twice as fun and energetic as any little brother before him. Then, as the robot turns on, he decides to name his new brother Brobot. Brobot then sits up and asks Jimmy what he wants to do, and Jimmy acts pleased with his work.

Next, Jimmy is shown introducing his new brother to his parents. Judy questions whether they can really call him Jimmy's brother, while Hugh is very taken with the new addition to the family.

The scene then changes to Jimmy and Brobot in the park. Jimmy is bouncing on a Pogo stick that he altered so that it can jump higher, which is the invention that he had wanted his friends to test at the beginning of the episode. Meanwhile, Brobot is busy complimenting his new brother. Jimmy then offers the invention to Brobot, which his brother then uses, and he bounces up far higher than Jimmy did. Brobot returns to the ground, claiming that he jumped over the moon, and excitedly asks to go there. Jimmy responds that anything's possible.

Jimmy and Brobot are then shown playing baseball, with Jimmy doing terribly, but Brobot being impressed none-the-less. Carl and Sheen then walk up, greeting Jimmy and questioning him about Brobot. Jimmy then explains about how Brobot is now his brother and Carl and Sheen are impressed. Brobot then asks to attempt to hit the baseball, and does much better than Jimmy had. Following that is a short montage of Jimmy and Brobot both attempting sports, with Brobot excelling past Jimmy in ability.

Sheen and Carl are then seen exclaiming how great Brobot is, making Jimmy upset. Jimmy then makes an effort to leave, with his two best friends only caring about if his brother can stay. Just then, Cindy and Libby show up, and are introduced to Brobot. The robot then approaches Cindy, whispering to her that Jimmy likes her. Jimmy protests while Brobot starts to tease him by singing "Jimmy's got a girlfriend". Libby, Cindy, Carl, and Sheen then leave with Brobot, leaving Jimmy feeling left out.

The scene then changes to Jimmy looking on as Hugh shows Brobot a photo album, and they seemingly ignore Jimmy. This continues as Judy brings snacks in for only Brobot and her husband, once again leaving Jimmy out.

Next, Jimmy takes a bath, which Brobot intrudes on his privacy. Brobot ends up with toothpaste all over his face, which causes Judy and Hugh to insist on taking his and Jimmy’s picture together, much to Jimmy’s annoyance. Brobot is then show annoying Jimmy, once again, as Jimmy is trying to fall asleep. His brother agrees to wait until the morning, at which point he picks up on asking Jimmy to play with him. Jimmy then agrees to introduce him to a new kind of game titled "One Way". The game consists of Brobot getting on a bus and going one way. Brobot complies to the game, but ends up back at home mere seconds later, which defeats the purpose for which Jimmy had devised said game. Jimmy had enough.

Jimmy and Brobot are then seen in the lab, with Brobot continuing to insist that they play a game. Jimmy then begins to deactivate him which upsets Brobot, saying that Jimmy is his big brother and they won't be able to play games anymore. Feeling guilty about this, Jimmy then sheds a tear which accidentally deactivates Brobot. Jimmy then says, "Oh, no! Brobot! Wh-what have I done?". But seconds later Brobot shows himself to still be functional and that he was tickled, excitedly saying that Jimmy made him indestructible.

Jimmy and Brobot then return to Jimmy’s room, where Jimmy attempts to make up a solution to his problem. He then looks out his window to see his parents and gets an idea. The scene then changes to show Brobot being introduced to Mombot and Popbot. The three then depart for the moon.

Jimmy is then seen in his lab, looking on through his computer as Brobot spends time with his new parents. Goddard then opens his screen and replays the scene from earlier in the episode where Brobot told Cindy that Jimmy liked her. Jimmy then chases Goddard around his lab, telling him to stop, and the episode ends.
