Caillou is an evil kid, he did so many bad things. Like, for example, he gave Rigby rabies in “Phineas and Ferb: The School Daze”, which resulted in him losing his right arm. He also snuck off to Chuck-E-Cheese’s in his Grounding Videos. Everything he does always results in him getting grounded by his parents. Tico used to be his partner-in-crime, but he started to dislike Caillou after he made him go savage in “Phineas and Ferb: Off to the Falls”. Caillou would always torment Boots by yelling at him, beating him up, and telling him to shut up. In earlier episodes, Caillou was actually nice to Boots, he’s even included him in him and Tico’s antics. Dora, being the girlfriend of Caillou, is completely unaware that he is a terrorist. Caillou is the only one of Tom’s friends who Trent actually likes. Later on in the series, Caillou retired as a terrorist and began acting kind towards others, even Boots. For Example, when Brian was kicked out of the house for posting a racist tweet, Stewie became depressed, so Caillou called Brian over to his house to cheer him up.
