In November 2015, Mog came back as a CGI character for the 2015 Christmas video advert for the supermarket, Sainsbury's. In "Mog's Christmas Calamity" Mog accidentally starts a fire in her house after having a bad dream. She saves her family by calling firefighters by running across the telephone and dialing the emergency number. She is a hero for saving her owners, and is later given an egg as a treat. A special plush Mog and book version of the story were sold at Sainsbury's, with all profits being donated to Save the Children's child literacy work.
