At the end of the episode, Caillou hosts the Sound Detective game, featuring sounds from musical instruments.
Between the second and third stories, Caillou sings a song titled "Caillou's Rock 'n Roll Band."
At the end of the show, Caillou talks about his Daddy. For a bonus, Rexy talks about himself. This is the first time two of these segments have been shown at the end of the program.
Leo: (reciting his made-up poem) Roses are red / I sleep in my bed / And this is my head.
Narrator: "Ring Around the Rosie" was Caillou's little sister's favorite song. Caillou decided he didn't want to sing it because it was a song for little, little kids.
Leo: I know the beginnings of lots of rhymes. I just don't know any endings.
Ms. Martin: Aren't you going to stop marching?
Caillou: I wish we were in a real marching band.
Narrator: Caillou couldn't take his eyes or ears off the marching band. The music made him want to march too.
Billy: Drums are for grown-ups, not little kids. Sorry.
Billy: I'm learning how to play the drums so I can be in a rock band.
Caillou: (observing pictures of rock musicians) Ha ha ha. They dress funny.
Billy: They dress cool.
Clementine: Ha ha. (whispers in Caillou's ear) I think they dress funny too.
