Also quite a role-reversal from
Equestria Girls, where after her whole experience being human in the mirror-verse, Twilight uses the word "
hands" and leaves her friends quite confused.
Actually, if Equestrians evolved like real-world horses, they
did have hooflets once. It was a sort of dewclaw on the side of the main hoof. Though horses/Ponies have lost theirs, their ungulate cousins--deer, cattle, and pigs--still have this extra toe. Twilight must have a book somewhere with drawings of their primitive cave-Pony ancestors (cue obligatory joke about one of the pics looking like someone they know, and said Pony happens to walk by and say "
Wuht?" as the girls giggle).
