Personality: In some series she acts like a blatantly stereotypical misandry radical feminist. In Caillou Gets Grounded videos or Rosie Gets Ungrounded videos she is mostly the dictionary definition of a Mary Sue, except in Rosie Gets Grounded videos where she is a troublemaker just like Caillou. Youtubers like StefieB and Rosie haters she is mostly a troublemaker in almost any case, which inspired others. In pre-2016 videos she is often well-behaved, so Caillou influencing her at some point in a certain timeline could in fact be a reason she became a troublemaker in other timelines because each of the characters are in different fictional alternative timelines. Relationships:
- Caillou and Rosie often show sibling rivalry that can go to intense situations. For instance, they may fight over Peter Piper Pizza vs Chuck E Cheese's.
- Caillou often does cruel pranks on her, such as dressing up as Pennywise and scaring her because she is afraid of clowns.
- She loves her mom and dad because they play favorites and sometimes prefer Rosie much more than Caillou. They sometimes call her their "angel" sometimes because she is mostly well-behaved.
- Rosie occasionally invites her friends to a sleepover, which Caillou takes pleasure in ruining them.f
- Rosie used to be afraid of clowns until Caillou dressed up as a clown to show her clowns aren't scary. (this was Doris's idea)
- In GoAnimate, Peter Piper Pizza is her favorite restaurant.
Voice: VoiceForge Shy Girl (most of the time in pre-2016 videos), Salli (most of the time since VoiceForge Shy Girl got removed from GoAnimate), Acapela Rosie (on some videos and on Caillou Fanatic Est 2004's videos), Ivy (some videos)
