A captured princess just wants a good night's sleep! Shhh... 
Kidnapped by the Demon King and imprisoned in his castle, Princess Syalis is...bored. 
The Monster Bird Egg Association's efforts to poach Cursed Musician prove short-lived as Odile's true motivations are revealed. Meanwhile, Silmoth brings some much-needed experience and dignity back to the Ten Guardians--right up until the princess enters the scene. Then, the residents of the Demon Castle discover the power of partying and Twilight is forced to decide whether a personal invitation to the Wild Avian Hotel is a deadly trap or a fun-filled opportunity. There's also puppies powering up, popularity polls, and pugnacious plants!
