The den takes on an international flavour as a Ghanaian entrepreneur brings in his chocolate drink startup, a Welsh couple hope to change our sleeping habits with their British-made woollen duvets, and the Den is filled with strange monsters when a pitch for a kids' storage device brings out the Dragons' inner children.
