Katy Perry: isn't she a doll?

I know that China can react quickly, but who knew that - in between topping up the churn with melamine - somebody could find time to create moulds to make small, plastic versions of Katy Perry so swiftly?

It turns out, though, that the Perry doll is not your mass-market cash-in. Oh, no, it's a limited edition cash-in instead. They're only making 500; so there will be a lot of disappointed children come Christmas day if she hasn't already turned into a American Nightmare by then.
