I think of this pony as Babs's older sister, Sunflower... or, at least, how she appears in the pony world. I also think of them as being the children of Aunt & Uncle Orange. I would love the idea of Sunflower giving Babs a little flight to lift her spirits after a bit of bullying...!
For some reason, the sunflower reminds me of Plants vs. Zombies. Besides the fact that sunflowers DO play a big part in PvZ, I don't know if the reason I thought of it this time is just because I'm up too late or what. XD
