Biography
Rosie Anderson was born in Plot City, CA on January 31st, 2005 and attends Plot City Middle School with Miss Martin as her teacher. She is a Non-Troublemaker (Like CoolBoy2127 suggests) and always gets ungrounded (even though she was never grounded to begin with :P)

Trivia

 * Caillou's groundings have involved Rosie in only one episode: "Caillou Misbehaves at Great Wolf Lodge"
 * Rosie has never referred to herself outside of third person. She talks this way because she thinks it's correct.
