CJ, Fenwick and Crispo start a garage band with hopes of winning the top prize at the school's music festival.
Mr. Bandt tells his health students about Pootaroo, Pootatuck's first music festival and encourages them to sign up. CJ shows interest in starting a band with Fenwick and Crispo, but they aren't as excited about the idea. Mr. Bandt gets agitated when no students want to sign up, and Mr. Roberts comes in to help. He offers a gift card to a restaurant as the first place prize, which motivates the students to sign up.
After Fenwick and Crispo agree to start a garage band, CJ begins to look for an outfit for their performance. CJ learns that her mother was in a band and she, her father, and and Ronbie help CJ choose an outfit. At school the next day, CJ, Fenwick, and Crispo look for a practice room, but learn they are all full. Mindy suggests that Crispo join her group since she is positive they are going to win. CJ gets the idea to have their band practice in her mother's car, and they name their band Robot Boy and have fun practicing.
The next day, however, they face creative differences. Fenwick writes a lengthy rock opera without consulting CJ and Crispo; CJ writes a song, but Fenwick does not think the audience would like the lyrics; and Crispo wants to use dry ice in their performance, but Fenwick doesn't agree. Later at CJ's house, Mrs. Martin wants to get her band back together for a reunion, and when he learns that the band's drummer is unavailable, Mr. Martin hints that he wants to fill in. Mrs. Martin doesn't pick up on the hints, but Ronbie does and mentions it to his mother. Mr. Martin tells them he doesn't want to join the band, however, and though Mrs. Martin is oblivious to his lie, Ronbie sees through it. They hear Robot Boy performing in the garage. The band members argue over song lyrics and special effects, and Fenwick and Crispo then quit.
The day of Pootaroo, CJ tries to get the band back together, but finds out that Crispo decided to join Mindy's group because he thinks they're going to win and that Fenwick started a group with the Froman twins, who enjoyed his rock opera. She sadly looks at the Pootaroo sign-up sheet and tells Mr. Roberts she is sad, explaining what happened with Robot Boy. He encourages her to perform by herself, and she signs up as a solo act. Fenwick has difficulty practicing with the Froman twins because they continue to interrupt their practice time. Crispo tries to add special effects to Mindy's group's performance, but she tells him they don't need any.
CJ sits in her mother's car thinking about Robot Boy and finds out Ronbie was also in the car, studying because Mr. Martin was drumming all over the house. Their parents join them in the car, and Ronbie gets Mr. Martin to admit to Mrs. Martin that he did want to join her band as a drummer. He expresses his fear of being a terrible drummer and Mrs. Martin tells him they were all going to be terrible, but their main objective was just having fun. The family has a silly jam-out session in the car, and CJ remembers that the most important thing when starting a garage band was having fun and wants to get Robot Boy back together.
At Pootaroo, CJ gets Crispo to rejoin, and they look for Fenwick. They find him annoyed at the Froman twins and ask him to rejoin their band. Fenwick does not want to just leave the Froman twins at the last minute, so CJ wishes them luck on stage. When the Froman twins find out they were supposed to perform in front of people, they run off screaming. Fenwick rejoins Robot Boy and agrees to change the lyrics of their song. They rush to the stage to perform, but Mindy shuts the power off. Mr. Roberts tells them they were going to have to end Pootaroo, but CJ comes up with another place for Robot Boy to perform: her mother's car. They use Crispo's effects and perform their new song, winning first place.

Mr. Bandt: I'm trying, people. Trying to keep the arts and Chuck alive in this school.
CJ's voice-over: So just like that, we became Robot Boy, and we were ready for the last step of forming a garage band. Step five: have fun. We played for hours, jamming, singing, laughing, just what I expected. But I wasn't expecting what happened the next day. Step six: creative differences.
Mr. Roberts: Hey, Miss Martin, you ready to rock out at Pootaroo tonight?
CJ: No. Robot Boy broke up and Crispo and Fen joined other bands and I'm really sad.
Mr. Roberts: I'm sorry, but if you were really looking forward to performing tonight, why don't you try going on without them? Look at what happened to Beyonce when she went out on her own.
CJ: Beyonce was in a band?
Mr. Roberts: Yeah. And always remember, when one door closes, another opens. That door might be you going solo.
CJ: You think I can win the spaghetti?
Mr. Roberts: Even if you don't, you win the Never Give Up award and [goes through his jacket's pocket and pulls out a handful of gift cards, holding out one to CJ] ten dollars to the Coffee Shack.
CJ: I don't really drink coffee.
Mr. Roberts: Okay, how 'bout, uh, twenty dollars at Home Max? [holds out another card] Who couldn't use a new hammer? [CJ takes the card]
CJ: Where did you get all these?
Mr. Roberts: End of the year thank you's from parents. They love me.
Mrs. Martin: Okay, sweetie, are you ready to rock Pootaroo?
Mrs. Martin: Ooh, and afterwards, I got almost all the girls to say yes to a Spit reunion, but we still don't have a drummer.
[Mr. Martin gets in the car]
Mr. Martin: Ooh, you still don't have a drummer? That is so sad. [drums on the car seats]
Ronbie: Mom, Dad wants to play.
Mrs. Martin: Sweetie, he said no.
Ronbie: But he doesn't mean it. Tell her.
Mr. Martin: No, I mean it.
CJ: No, you don't.
Mrs. Martin: Hon, do you want to play drums in Spit?
Mr. Martin: Oh, well, I -
Mr. Martin: More than anything, but I'll probably be terrible!
Mrs. Martin: Oh, we're all gonna be terrible, but the point is to just have fun.
CJ's voice-over: So when you start a garage band, try and stick to the first five steps: grab your friends, a cool look, an awesome place to play, and just have fun. And if you have horrible stage fright like the Fromans, just don't go on stage, but do grab your friends, write a song, and sing it. I guarantee you will have fun.
