It is another busy week in the Den as eight more entrepreneurs pitch to the Dragons for a cash injection in their money-making ideas. Often, a visual aid helps get across what is being pitched, and this time there is a plethora of props to help the multimillionaires understand the commercial potential of the businesses on offer. A ballroom dancer turned inventor brings a bit of sparkle into the Den via a tango and a glitter ball; Theo Paphitis and Peter Jones crawl into a new concept for the camping industry; and a labrador called Margot helps to sell the idea of doggy ice cream. Also in the Den: a world kickboxing champion, two Welshmen with their celebrity-backed toffee vodka, and three friends from London who hope to capitalise on empty loft space.
