Caillou goes out caroling for the very first time with Mommy, Daddy, Rosie, Grandpa and Grandma. He finds out caroling is lots of fun – you get to stay up late and surprise your friends with carols, and you even get treats! They finish up the night with a big finale at the seniors’ home and Caillou imagines he’s really ‘dashing through the snow’ in a horse and sleigh.
