"The Best Bad Day Ever" by Marianna Coppo

Today is a terrible day for Wolfie: it's cloudy (there is a single cloud), the water in the bubble bath is ice cold, there aren't enough chocolate chips in the cookies and everyone else is having a nice day (lucky them). No one understands Wolfie at school. But then Penguin comes along... and she does understand. Suddenly things start to get a whole lot better.
