Aren't the ponies in the show expected to be like 18-ish?
Or teenager or something
they have not been given ages in relation to humans (or as ponies either, actually), excluding fanon.
mentally, Lauren Faust said she'd put them from 12-19. this is technically not canon either.
what is known is they are mares. these are adult-horses with no real known ages.
also, Fluttershy is a year older than Pinkie Pie.
