In anticipation of a family-friendly box office smash, Mattel and others have produced a lot of merchandise for the film. The porn-linking toys were singing Glinda and Elphaba dolls. Retailers such as Target and Walmart have already delisted the toy from their online databases, but pictures of them still exist on eBay.

Mattel is pulling its Wicked dolls from some store shelves because of a misprint directing shoppers to a pornographic site. Meanwhile, resellers are listing the products on eBay for up to $500.

The site has a similar address to one that promotes a film adaptation of the hit musical. The toymaker apologized for the “unfortunate error.”
