A North Herts uncle has expressed his shock at finding an advert for an adult porn site on the packaging of a doll he had bought for his niece for Christmas.

Fans have spotted an X-rated mistake on the packaging of Mattel's highly anticipated 'Wicked' doll collection.

A link at the back of the box directs customers to a porn site with a similar URL, instead of the movie's landing page, wickedmovie.com.

An uncle from North Herts, who goes by the handle Grumpy Man UK on X (formerly Twitter), said: "I went out and bought these Christmas toys for my niece. The web address on the packaging goes to an adult website!

"Kids toys that advertise an adult website. Outrageous!"
