It wasn't a mistake, it's a sign of the times. They shouldn't even be making and promoting "Wicked" dolls for 4 year old, much less printing porn sites on their boxes.

Mattel faults print error for porn site listed on "Wicked" doll packaging - CBS News
Mattel apologizes for inadvertently directing people to pornography site instead of one promoting upcoming film.

Wasn't a "misprint" or "bad link" ... the website was clearly printed as exactly how it *would* have been if it was the *right* one ... thus it *was* the right one.
Now someone could have hacked the site and misdirected the incoming traffic to that porn site (I *think*?) but Disney isn't even claiming that so what does that leave one to surmise?
