According to Sky News:

A toy company has mistakenly printed the address for a porn website on the packaging of Wicked dolls.

Mattel released dolls of characters played by British actress Cynthia Erivo and US singer Ariana Grande in the film version of the hit Broadway and West End musical.

But instead of featuring an address to the movie's website, a porn site sharing the name of the movie was printed on the packaging.

Apparently Mattel advised parents that the incorrect website is not appropriate for children.

But presumably is OK for parents.

Now that's not just a bit naughty but truly wicked!
