Rosie Tollar, is Caillou's adorable and very beautiful 8 year old little sister. In the French novels by Christine L'Heureux that the show is based on, her name is Moussline. She is also the daughter of Boris and Doris.
In Caillou, Rosie tended to cry over almost anything (usually resulting in her needing to be comforted by either parent), yet she can giggle at anything she sees as funny (both normal behaviors for kids her age). Calliou usually showed love to Rosie (despite some quarrels between the two). In the Caillou 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. She couldn't talk as well Caillou can (usually just short sentences (some even being one word or a sound effect) plus speaking in the third person most of the time). 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". She's developed a lot in the later seasons. In "Caillou Helps Out" Rosie starts teething, and in "Am I Big Yet?" She went through a growth spout. In School Daze, Rosie has changed a lot. She now cries less often than she did when she was 2. She is able to speak fluently. She would often bother Caillou whenever he was using the computer. Rosie is shown to love animals a lot. In “Triple Birthday Party”, She is seen cuddling with Rigby throughout the whole episode. She is shown to find Brian very adorable in “What you Read is What you Get”. But other than that, she thinks Gilbert is the cutest animal of them all.
