With the recent shop update to Gaia Online, all the NPCs got new art. Ruby's shop art was changed from a southern belle's outfit to what appears to be a fairy's outfit, in accordance to her shop's change from only selling hats to the much wider range of "cute, quirky and quintessentially Gaian styles". I thought "oh, okay, quirky, I get it, I guess." Later, I realized that her fairy's outfit was not a fairy's outfit, but actually represented a goddess's outfit—in other words, her new outfit is based on the goddess Gaia. Brilliant. — Shroopliss
Alternately, it could be an angel outfit, in honor of the rumor that characters who failed the Save Our Shops event would be removed from the site and functionally "dead". — Yuihime
Back a few years ago, before the Vampire themed Hallowe'en [before we knew it was vampires], Edmund had us collect orchids and garlic. I never quite got the point of the orchids until I read the Flower Motifs page [and it still took a bit]. Much like vampires, orchids are parasitic.
Gaian vampires can eat human-style food, they just find it unpleasant. This explains the non-canon storyline where Louie would have been a literal Vegetarian Vampire.
