Here in America, McDonald's makes green shakes in March to celebrate Irish heritage. In Japan this summer, another chain is making a blue milkshake with chocolate "hair" to call attention to global warming - all while utilizing a demonic drowned girl who deserved her watery grave as a call to awareness.

Now, if you wanted to use her as a mascot for Lasik surgery, I can see that.
