sanrio japan now has some items featuring hello kitty with a mouth.
here is a translation that does not make much sense...
Kitty PUCHITAORU type face and the back of the leg is to be unique magnet wire mascot, Kitty charm with a three-point set of rubber hair. どれもにっこりフェイスで揃えたよ。 None smiled揃えたface.
(notice that hello kitty with a mouth is missing one nose!)
