Behind the scenes
Big Jim mentioned "Big Sugar" as a placeholder name until the fans could come up with a better name, as the writers never gave him one officially. He appeared as one of the three known children born during the Era of Twilight's reign, alongside Luster Dawn and Little Cheese.

In "Cutie Mark Deuxsaders", he is referred to as Tinyhorse as a codename, but in the game proper, he's just referred to as Apple Foal with the description for his future self noting that they don't know his name either.
