It's a Den full of family businesses. Tim and Meena Kalia and their business partner Tricia Tierney try to talk the Dragons into investing in their innovative litter trays for dogs. The Den is taken over by a pirate, a street urchin and a hippy as Peter and Michelle Hart, plus five of their seven children, pitch their fancy dress business; but is their dream of investment pure fantasy? Brothers Jim and Richard George from Malvern believe they're in a strong position with their fence preservation company which is already trading. The business-savvy siblings have a deal in mind - but will the offer they're holding out for materialize?

Others looking for Dragon investment include an 'all you can drink' membership club, an exercise suit that claims to burn extra calories, and some giant knitting needles.
