I Am Catherine the Great is an episode of Xavier Riddle and the Secret Museum.
Brad shows up ready for day camp with a pep in his step and a smile on his face, until he finds out that he's going without Xavier or Yadina. Uh oh. Brad can't possibly go without his best friends! Who will he play with? Xavier and Yadina are sure Brad will make new friends at camp, but Brad isn't so sure - he doesn't know how. To the Secret Museum! Our heroes go back in time to meet someone who made all kids of friends: Catherine the Great. They find Catherine wandering outside her castle walls, simply so she can make some new friends to play with. Watching Catherine meet new kids, and ask them questions about themselves, shows Brad that getting to know people is a great way to make friends.
Getting to know people is a great way to make friends.
I Am Catherine the Great, along with its sister episode, I Am Tomioka Tessai, was released on the PBS Kids website and video app on November 11, 2019. Both episodes aired 9 days later on PBS at 9:00 AM EST.
Brad possibly has a crush on Catherine the Great, as he is nervous around her and blushes a lot when she holds his hand (similar to how Yadina reacted to George Washington)
The closed captions mistakenly attribute the line "we're gonna play in a real castle" to both Xavier and Yadina, when actually it is only Yadina who says it and Xavier merely nods in agreement
