Caillou
Doris/Mommy – Caillou's mother. She is a busy homemaker most of the time but is seen to work in an office, as well. Caillou occasionally helps his mother with different chores, and she often takes time to involve Caillou and his friends in activities such as crafts and baking. She is predominantly dressed in a red blouse with yellow trim, blue headband, ankle-length blue jeans and blue shoes with green soles. Voiced by Jennifer Seguin.
