Caillou is excited because Clementine is coming over for a playdate. Unfortunately for him, Clementine starts going through his stuffed animals and wants have a tea party, but Caillou wants to play with dinosaurs.
Caillou throws a fit and screams in Clementine's face. Oblivious to this, Clementine suggests the dinosaurs be their children which makes Caillou run crying to his mommy.
In the end, Caillou apologizes to Clementine. Clementine's older brother, Billy (who is a baseball champion) comes over to play catch with them and they have juice soon after that.
- Clementine's mom
- Rosie (cameo)
- This is the first appearance of Billy.
- The title is somewhat misleading, as Caillou actually did all of the quarreling while Clementine tried to calm him down.
- Clementine apologizes though it appears as if she has done nothing wrong, though she probably said it to soothe Caillou's hurt feelings.
- Billy's voice is different than other episodes
- Gilbert and Boris are absent in this episode.
- Rosie has no dialogue in this episode.
- This episode was banned because Clementine was being bossy and Caillou was fighting with her.
