Connections with previous events
- The Amulet of Avalor gave Sofia the power to talk to animals in the pilot movie, Sofia the First: Once Upon a Princess.
- The title is a play on "Just one of the guys."
- Disney Press published a book adaptation in the World of Reading line on June 3, 2014.
- Eventually, Sofia will influence some of the princesses to take part in flying horses, as seen in "Substitute Cedric", and even Amber in "Minimus is Missing".
Sofia: It gives me the power to talk to animals.
Minimus: Well, then, let me give you a piece of advice. If you want to win, you'll pick another horse. You see, I have short legs, small wings, I don't fly fast, I worry about everything. (shudders) Oh...
'Sofia: (chuckles) I think you're perfect, just the way you are.
Princess Hildegard: Amber, is that your sister up there?
Amber: Oh. I can't believe she's really doing it.
Sofia: I can't even make it to the finish line, and I only have one more day until the race. Amber said I should quit. I don't know what to do.
Robin: My mother had a saying. The early bird gets the worm.
Mia: What does Sofia need a worm for?
Clover: She doesn't, Mia. Hey, what Robin's trying to say is, get an early start tomorrow.
Amber: You were great, Sofia. I was wrong. Flying derby is a princess thing.
