Mrs. Martin gives Caillou some juice. Caillou then tries to befriend Leo, but Leo was rude to him. Enters Clementine. She introduces herself to Caillou, and explains to Caillou that Leo "doesn't like to share". She shows Caillou what she has been doing: cutouts. She then asks Caillou why does he prefers his grandparents' place. He tells her that he likes painting. She explains to him that they can do that at daycare, too. She brings out some paints, brushes and paper. Caillou paints a robin as Clementine cuts out some paper worms. Leo walks by, and notices Caillou's painting of a robin. He wants Caillou to teach him how to paint. Caillou aggrees, on the condition that Leo teach Clementine and him how to build castles with blocks.
