One day, Dude decides that he wants to do nice things for his friends and neighbours all day long. But Dude isn't exactly attentive and tends to forget the most crucial part of helping people: asking first. So when Dude unravels a sweater, frees some dogs, and ruins an ice cream social, he needs to reckon with his own niceness: is it really nice if he wasn't that helpful? Can Dude and his best friend Fizz save the day before Dude makes too big of a mess?
