I don't have anything hanging from my DS Lite, but my girlfriend does (a random Pokemon), and I've started to notice that most female DS owners do as well.
While taking in an outdoor screening of sci-fi classic "It Came From Outer Space" in Dolores Park, I snapped a shot of two women with items dangling from their DS. One of them was a character from "Animal Crossing."
Maybe it's just a San Francisco thing, but I doubt it. Female (or male!) MTV Multiplayer readers, what items do you have dangling from your DS?
