Caillou is a whiny little French-Canadian spoiled brat who is part of The Barney Bunch, alongside Barney, Elmo, Dora the Explorer, Chuck E. Cheese, and the Teletubbies. Just like the rest of them, he has secret evil intentions. One time, he hung around the neck of Hal Esposito and almost choked him to death. His WAY-too parents only lightly scolded him for that yet he still cried and whined like a little baby that he is. That was just one out of many instances of his heinous crimes that his parents were just bribed to look the other way. He also once left Karen Johnson tied to a pole, helped Clurkicus steal an innocent victim's soul and made Colton Williams lose control by spitting on his shoes which lead him to be chased all around by Williams' Gang. He barely escaped their clutches out alive.
Since 2016, he has also been working as a part of the Chaosworld's left-wing freedom cult named Chaos Eighties and has been spreading their false propaganda around multiple planets save for Earth... For now.
