During the first season, many of the stories in the animated version began with a grandmother (who is also the show's narrator) introducing the story to her grandchildren, then reading the story about the book. Since 1997, the narrator/grandmother is an unseen character.

Caillou ("pebble" or "stone" in French), nicknamed The Prince of Imagination, is the title character of the show. Caillou was first voiced by Bryn McAuley from 1997 through 2000, then Jaclyn Linetsky in 2000 through 2003, and then, due to Linetsky's death, Annie Bovaird from 2003 through 2010. Caillou was first shown in the episode "Caillou Makes Cookies", which aired in 1997.

Caillou is an average, imaginative four-year-old boy with a love for forms of transportive machinery such as rocket ships and airplanes. A dreamer, Caillou is prone to frequent dream sequences in some episodes, visualizing his daydreams and hopes, and many episodes chronicle his normal daily experiences with his parents, friends, and neighbours. Caillou particularly loves his stuffed dinosaur Rexy and teddy bear Teddy, along with his pet cat Gilbert, all of whom are depicted as puppets in segments featured in the earlier episodes.

Caillou's family

In later seasons of the series she becomes more talkative and independent. She wears a blue dress, red socks and blue Mary Jane shoes.

  • The puppets

  • Episodes

    Caillou consists of 5 seasons of 92 half-hour episodes, as well as the separate 90-minute children's film Caillou's Holiday Movie.


    Caillou books have been made since 1989 by Chouette Publishing Inc.

    The series was originally broadcast in French in Canada, and the episodes were later translated into English, and re-runs in English began on PBS and PBS Kids Sprout in the United States. The original books were also in French. Caillou was designed primarily for toddlers. It was created by child developmental psychologists.

    In 1997, 65 5-minute episodes of Caillou were aired in Canada and in selected markets worldwide, including the US, as mentioned above. In 2000 there were 40 30-minute episodes of the show, containing a mixture of the 5-minute episodes plus new stories, songs, real kids segment and puppets. This was followed by another 16 30-minute episodes containing all-new stories in 2003. The film Caillou's Holiday Movie was released on October 7, 2003.

    On April 3, 2005, a new set of 20 episodes finally premiered after a three-year hiatus. Caillou started attending preschool and there were new themes and a new opening. While the original episodes were made by a South Korean company, the producers animated the new episodes in-house using Adobe Flash. On November 14, 2012, PBS Kids announced a 4th season of Caillou of 26 episodes to premiere March 11, 2013.

    The year 2014 is celebrated as the franchise's 25th anniversary. For the 25th anniversary, a special DVD/book combo pack was released, as well as a reissue of the holiday film Caillou's Holiday Movie featuring a special 25th anniversary logo on the cover artwork.


    A 2011 study conducted at the University of Virginia, published in the journal Pediatrics, tested the show's effect on preschool-aged children's attention spans and cognitive abilities. The study had three groups of four-year-olds each engaged in activities; one group watched Caillou, another watched SpongeBob SquarePants, and the third group drew pictures. After nine minutes, the children were tested on mental functions; those that watched Caillou had very similar results to the group that drew pictures, both of whom performed significantly better than the group that watched the SpongeBob episode.

    As Caillou appeared as a much younger child in the original line of children's books, the character originally had no hair. When illustrators found that adding hair made the character unrecognizable, it was decided that Caillou would never have hair.

    Caillou has used been as the primary character in the majority of videos that are a part of an online subculture known as "grounded videos", which are commonly made with programs such as GoAnimate and Plotagon and mainly depict the main character getting grounded by authority for breaking a rule.


    Caillou first aired on Canada's French-language Télétoon channel on September 15, 1997, and was the first show aired on the English-language Teletoon when it launched on October 17, 1997. The show later left its original channels; it joined Treehouse TV on September 7, 2009, and subsequently began airing new episodes on that channel.

    Caillou made its United States debut on PBS Kids from September 4, 2000-2010 (some PBS stations air reruns). It has also aired on PBS Kids Sprout from 2005-2013, Sprout since 2013, and Cartoonito since 2007.

    Home video releases

    The DVDs with puppets and Jaclyn Linetsky were compilations from 2003 through 2006, and one of them is in memory of Jaclyn herself. The new DVDs from 2006 through 2010, were from Paramount Home Entertainment. There was also an album issued in 2003 titled Caillou's Favorite Songs.
