Caillou is awoken by a thunderstorm. Caillou spends the day with Miss Martin, Clementine and Leo on a nature hike through the woods. When Caillou sees Dad painting the house he wants to join in on the fun and he's disappointed when Dad suggests that he should paint a card for Grandma instead. It's a beautiful autumn day and Caillou wants to spend the entire day outside playing in the leaves.
