Say Hello to Xavier Riddle and the Secret Museum!

Your new favorite crew of adventurers…

Xavier Riddle and the Secret Museum is an animated children’s television series based on the best-selling books Ordinary People Change the World by Brad Meltzer and Chris Eliopoulos. In this adventure-comedy, kids can follow along with Xavier, his little sister Yadina, and best friend Brad as they travel through time to meet famous heroes of the past and learn how to be their own heroes!

Xavier Riddle and the Secret Museum offers relatable and meaningful takeaways for parents and children. Through the demonstration of social-emotional problems in each themed episode, we learn that each child faces their own obstacles, challenges their own fears, and learns in their own unique way. By meeting these famous figures from history when they were kids, children are able to learn that everyone can be a hero.

The series premiered in November 2019, and has been nominated for both a 2020 Daytime Emmy and two Annie awards, and most recently it was recognized with a Parent’s Choice Gold award.

Xavier Riddle and the Secret Museum is available now to watch on PBS KIDS and PBS KIDS app or online!
