Everyone in Circus Town is excited when royalty from Really Royal Land comes to visit. JoJo in particular is eager to welcome them as she gets to meet her cousin Princess Josephina for the first time. It turns out that Josephina looks just like JoJo and has a pet lion named Hercules who looks just like Goliath. JoJo and Josephina visit JoJo's room, where they have fun dressing up as each other and decide to trade places. Unfortunately, Josephina has forgotten that today is her coronation day, and she must set things right before JoJo is crowned princess of Really Royal Land - forever!
- This episode is highly based on the Mark Twain novel "The Prince and the Pauper," with Josephina portraying the upper-class prince and JoJo portraying the lower-class pauper, who switch places for a while.
