Knickknack is throwing a Fat Cat board game tournament but, on the day of the tournament, Candace steals all their Kitty Cash. Jarvis and the gang have to somehow get their cash out of a bank vault before the tournament starts.
Jarvis decides to give Candace a second chance and hires her to be Mrs. Bubkes's assistant. But when a young girl uses a Knickknack toy to save a life, Candace sees it as a chance to regain the spotlight.
When pop star Caden Clark hides from his crazed fans at KnickKnack Toys, he discovers he loves Knickknack's "Pop Superstar" video game - and decides to quit real superstardom to play the video game full-time.
In Jarvis's dream, he creates the world's greatest new toy - but now that he's woken up, he can't remember what it is. Piper, Bowie, and Aster try to recreate the events of the day to help Jarvis have the same dream again.
