Lord Sugar tasks his candidates with marketing a brand-new electric toothbrush aimed at children aged between six and eight. They must also create an accompanying app that encourages youngsters to brush their teeth before pitching their package to two major buyers. One team takes on an intergalactic space theme with hopes of it rocketing them to success, while the other takes a chance with a magical masterplan. As usual, Karren Brady and Tim Campbell act as Lord Sugar's eyes and ears on the ground.
