Daniel

Daniel is an older kid friend of Caillou. He has somewhat longish brown hair and is normally seen wearing a red shirt with a green undershirt and blue jeans.

In "The Spider Issue," Daniel shares with Caillou a comic about a "mutant spider from cosmic space," but this causes Caillou to become afraid of spiders. In "Caillou Roller Skates," Caillou meets Daniel at the park trying out a new pair of inline skates. He tells Caillou that he got good at skating by practicing a lot and helps him to practice.
