Sofia the First: The Joke Is On You

Sofia and Prince Hugo are excited to paricipate in Silly Sports Day at Corinthian Sports, except that for the occassion, some students from the School of Royal Fashions are coming, one of them being Hildegard. She doesn't quite understand what makes this day fun, and Sofia gets back at her for her remark about King Roland II being no more than her stepfather by saying that Hildy doesn't have what it takes to fit in at Corinthian Sports. Hildegard is determined to prove Sofia wrong and joins the fun, but then she starts playing bad jokes continuously, not even thinking about how her victims feel. It's all fun and games until she accidentally plays a prank that appears to have backfired.
