About Rosie

  • Rosie tends to cry over everything.
  • Calliou usually shows love to Rosie. In the episodes "Halloween" and "Caillou's a Clown", she was scared of clowns, but he was able to convince her to not be afraid of them.
  • It is shown in "Olive Muddle" that Rosie likes olives.
  • Rosie's favourite song is "Ring Around the Rosie."
  • Rosie does not like beans, as shown in the episode "Caillou becomes a waiter".
