This episode sees Londoners Krissy Sims and Kerry O'Brien AKA DJ Trickles and Lady MC enter the Den with a state-of-the-art turntable extravaganza in the back of their 4x4. The Dragons are often happy to demo a product but it is the business and how it makes money that remains their ultimate concern. Husband and wife team Liz and Alan Colleran from Dewsbury may be pitching their comfy caravan product - but will their Den experience be quite so luxurious and comfortable?Elsewhere, an Englishman, a Norwegian and a Scot walk into the Den. Shades for canines are on offer, there's an inflatable car-based device like you have never seen before and a Kent-based entrepreneur thinks honesty is the best policy when pitching without a formal business plan - but with an offer to help everyone get the perfect looking body for just 20 pounds.
