An 18-year-old seeks to impress the Dragons with his garden shed invention. There is also a canine member of Team GB and a rip-roaring entrance from a Kent-based gaming entrepreneur. Also, a couple of likely lads showcase their blooming marvellous greetings product and the Dragons get a taste of Colombia's finest cacao.

The Den is full of eye-catching businesses - male leggings, hi-vis sportswear, sandwich boards with a difference and an energy-efficient light bulb all come up against the Dragons' scrutiny. Alongside that, a young photo-booth company offers the Dragons the chance to capture their time in the Den, and Deborah takes a stroll on a lawn to test out a new stiletto accessory. Will anyone leave the Den with a Dragon on board, or will it be lights out on their investment hopes?
