Xavier Riddle and the Secret Museum
I am Wilma Rudolph/I am Jonas Salk
S1 E28:
Xavier shows up for his very first track and field meet and is dismayed to realize the other kids have had a lot more practice than him. He might never catch up! The heroes jump back in time to meet an amazing racer: Wilma Rudolph. Then, Jonas Salk shows the kids that they don't need a reward for shoveling the museum steps, because it feels good to help others!
