Caillou is an extremely popular character in the GoAnimate community, mostly depicted as a troublemaker. In fact, he is likely the "mascot" of the GoAnimate community. He was originally a character from the Canadian children's TV series Caillou. He is a four-year old boy living with his parents Boris and Doris, his little sister Rosie and his cat Gilbert. In the eyes of many GoAnimate creators, Caillou is a violent troublemaker, living under the thumb of his insane parents, and demonstrates troubling behaviors, an obsession with fast food, most comamonly Chuck E Cheese's and a strong dislike of his younger sister. He attends pre-school with a few other kids, under Ms. Martin, a strict and abusive teacher.


Caillou is a bald four-year old boy with a round face. He wears a yellow shirt with a red neckline, blue shorts and red sneakers. His size varies through the countless videos he is in, but he is most commonly shown as being a fair bit smaller than his parents, though larger than Rosie. His age also varies from series to series, mostly from 4 to 12 years old.

Being a popular GoAnimate character, Caillou's appearance varies from video to video, with some creators preferring a more accurate look, and some adding their personal touches to his design. A gallery exists to catalogue his various designs.


Caillou lives with his parents, his father Boris, his mother Doris and his little sister Rosie. He lives close to his grandparents, who insult him quite often.

Caillou also has a cousin called Mella (she is canon and was created by Hélène Desputeaux, Caillou's creator) but she is very rarely seen in GoAnimate videos.

In some GoAnimate videos, Caillou is shown to have identical twins, sometimes only one or two, most commonly Daillou and Baillou . In more extreme cases, Caillou has one sibling with the -aillou theme for every letter. These twins are usually just recolored versions of Caillou, though some creators have made effort to give his siblings unique looks and personalities. In other videos, Caillou is shown to have another younger sister named Daisy. Other users have also added their own members to Caillou's family.


The name Caillou originates from the French term "caillou", which defines any small rock you normally see outside ("pebble" or "small rock") because Caillou is bald like a rock. His last name is never stated in the actual Caillou series, and as such, many GoAnimate users have given Caillou made-up ones, the most common being Caillou, meaning he has the same first and last name, or Anderson, a reference to popular GoAnimator Isaac Anderson. Due to the French spelling of his name, most GoAnimate videos mispronounce his name. The official pronounciation of his name is "Kah-you", though most GoAnimate voices render his name as "Kaylew" or "Kay-Eye-Ew".

However, the original creator of Caillou, Hélène Desputeaux, stated that she had originally created a baby named "Bertrand" as a precursor to Caillou, so this might maybe be Caillou's middle name.

In real life

Caillou was originally first created in April 1989 by Hélène Desputeaux, who had drawn him for the first time at this time as she was pregnant with her daughter. In 1997, the TV show was first aired on Teletoon in Canada, and Caillou was the first program to ever air on this channel. But eventually Caillou was taken off from Teletoon.
