Caillou is very sad when his snowman melts away in the warm spring sunshine. He doesn’t want winter to end. He helps Daddy clean up the yard and learns about composting. And during a walk in the park he is reminded of all the good things about spring – the birds returning, the warm weather, the fun things he can do outside. By the time they return home and Caillou finds the first crocuses of spring, he has decided that he’s glad spring is here.
