In this episode, we talk about what makes us happy and also find out what makes some of the Blue's Clues characters happy. Periwinkle likes magic, of course and Shovel has a favorite animal he likes to do impressions of. Joe's happy just to see us because we're so helpful. Unfortunately, sometimes we aren't always happy, as we find out in the Blue Skiddoo segment. There, we find several characters that are having problems and help them to solve their problems so that they're happy again.
