Barbie producer Mattel has issued an apology after customers spotted its Wicked edition dolls listed an adult website on the packaging. The toy merchandise mistakenly directed customers to the homepage of the Wicked Pictures pornographic movie studio, instead of the correct WickedMovie.com URL.

“We deeply regret this unfortunate error and are taking immediate action to remedy this,” Mattel said in a statement to The Hollywood Reporter. “Parents are advised that the misprinted, incorrect website is not appropriate for children.”

Mattel said that the dolls, which have been released to coincide with Universal’s film adaptation of the Tony Award-winning musical, are “primarily sold in the US” and that the error was a “misprint.” It’s unclear how many of the mislabeled toys, which are advertised for children aged four and up, have already been distributed to stores. According to The Hollywood Reporter, impacted products from the toy line are currently being pulled from shelves at various retailers including Walmart. Best Buy, and Amazon.

Mattel has advised customers who have already purchased the dolls, which retail between $24.99 to $39.99, to “discard the product packaging or obscure the link.” Some are taking financial advantage of the blunder, however — products advertised to specifically include the printing error are being listed on eBay for hundreds of dollars.

Wicked serves as a prequel to The Wizard of Oz that’s told from the perspective of the witches Elphaba (Cynthia Erivo) and Galinda (Ariana Grande). Part one of Wicked will debut in theaters on November 22nd, with a second film expected to release in November 2025.
