What do cartoon boobies smell like? I'm not sure anybody really knows, but we're all about to find out if we really want to. These phone straps based on the Senran Kagura video games boast a "faint breast scent" as a special feature. Considering that they're teenagers, and being trained in the art of ninjitsu, the real-life version of that would just be something most people call "sweat."
I'm guessing the manufacturers of this have something else in mind. And I've no idea what it is, but it reminds me a bit of when Playmates released the "Toon Turtles" toys with "real toon feel." Because of course, the only problem with animation is that we can't touch or smell it.
