If you look at the lyrics for this song, then you will see that in a line the singer says "There is no bad, there is no good I drank all the blood that I could Made myself mythical, tried to be real Saw the future in the face of a Daffodil" I think that this means that Featherstar saw a future that she wasn't supposed to see before she made her fur cover her eye, and that gave her a flower eye. Maybe soon, Featherstar will somehow show someone her eye (maybe Volepaw), and the them how she got it. LIke I said, smol theory
