Happy Glow is Honey Shine's niece, who is the daughter of Shine's older sister (who I have yet to design), who always seems to stick her nose in Honey Shine's life even when said pony isn't even around (she just loves her little sister so much is all xD). I always pictured her as someone eccentric and does whatever she wants, whenever she wants - though all within good intentions. It would probably explain why Happy Glow behaves the way she does too! Her sister travels a lot (for reasons currently not specified) so she leaves Happy Glow under Honey or Heavy's care every now and then, but I'm imagining that when she DOES come to visit in person, Honey Shine would be a TAD worried how other ponies might find her sister.
Aside from that, Happy Glow is kind of right! Will Honey Shine ever find that special pony?
This is so sweet a picture that I couldn't help but say aww! XD Happy Glow is right . Honey Shine will find some special pony someday, just not right now. She's a busy mare right now though. Lovely sketch here ^^
Would be difference, but also kinda awesome, if Honey fell in love with a Zebra, plus they're really good at medicinal plants as well aren't they? They might be able to help with her allergies lol
