S1·E4 Caillou's All Alone

Mom is very busy with the household accounts so she doesn’t have time to play with Caillou. Nor does Dad, who’s trying to fix the washing machine. And Grandma’s busy looking after Rosie. Even Gilbert the cat doesn’t want to play with him. Caillou is all alone and feeling a bit sorry for himself. But pretty soon he invents a game with one of his dinosaurs and then he’s too busy to play with everyone else.
