Caillou's Grandma is surprised when Caillou tells her he doesn't have any friends. She reminds him about Clementine, Leo, his cat Gilbert, and tells him that even his sister Rosie is his friend. Then, Caillou makes a brand-new friend. His name is Andre and he's big - and also a bit clumsy. Caillou is upset with Andre when he breaks Caillou's favorite chair, but it's soon forgotten when they go outside and play soccer. Later, Caillou and Leo are having a great time playing when Leo trips and falls, hurting his ankle. Caillou is very worried about Leo and thinks it may be his fault Leo got hurt. But when he makes Leo a get-well card and visits him at home, Leo says it wasn't Caillou's fault he didn't tie his shoelaces. Sarah helps Caillou paint a birdhouse Dad built, but she can't finish it because she is off on an all-summer trip to China. Caillou misses her very much. On the day of her return, Caillou is ecstatic and anxious to show Sarah that not only is the birdhouse finished and hanging in a tree, it has a resident.
