Throughout the series the advert buffers for the programme's sponsors, the supermarket chain Lidl, featured a celebrity dressed in a goose costume dancing and giving clues to their identity by the items that they picked up off the shelves and put into their shopping trolley. Viewers at home could win a prize from the sponsor if they correctly guessed the identity of Goose via social media. In the final ad buffer of the Grand Final the mask was removed to reveal reality television star Dani Dyer was Goose.
