Bon Bon Buddies is hoping to boost traffic along biscuit aisles with packs of shortbread that feature Cars, the latest Pixar animation.

The mini shortbread biscuits come in the shape of the film's two main characters - racing car Lightning McQueen and pick-up truck Mater - and contain no artificial colours or preservatives.

They will be available in Asda from the end of this month and in Tesco from the middle of next month.
