Four-year-old Caillou (voiced by Annie Bovaird) is the bald-headed protagonist of the Canadian PBS Kids' show Caillou.  Caillou is often considered the bane of parents of young children because his antics on the show are considered spoiled and bratty by many adults.  Caillou's outfit consists of bright primary colors.  If you choose to include a hat like Caillou's, you can purchase a novelty baseball cap with multicolored panels like the one shown here and remove the propeller, as finding a standard cap with multicolor panels can be difficult.
