Also raises an interesting point concerning ponies who have names directly derived from their cutie marks. Do pony parents have the supernatural ability to appropriately name their children without meaning to? Or do they change it when they're older if they decide they want to?
And what about those ponies who have cutie marks linked to professions that require years of study? How does a pony realise they're supposed to be a cardiologist when they're young?
