Character killed off, as having died from complications of a stroke he had suffered after the series' main setting, Walnut Grove (the town which he founded), had fallen into an economic depression.The final episode that featured his character aired eight days after his death.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 from a book, since the second season, the narrator/grandmother is an unseen character. There are 23 major characters and currently 66 minor characters, making a total of 89 characters.Caillou (pebble or stone in French), nicknamed The Prince of Imagination, is the title character of the show.
His job was saved but the actor died shortly after the episode was filmed.
Caillou was first voiced by Bryn Mc Auley 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.
Finally, in the very special episode "Raul Runs Away," aired January 20, 1978 (nearly one year after Prinze's death), it is explained that Chico had died but with no explanation of the circumstances.
However, the ratings declined and, with Prinze's death a primary factor, the series was cancelled in the spring of 1978.
