I understand the series is based on a series of children's biographies. I'm gonna hope they don't skip the Billie Jean King one
From the book Turkey Trouble, which I read to my toddler every year on Thanksgiving.
These cows give me the creeps!
It started off as a French childrens book series oddly enough. I know it comes off as one of those "shows we made so we can sell you merch" franchises, and it mostly is, but it didn't start that way at least.
