There are some true inventors in the Den this episode, including a returning entrepreneur with a new outdoor space saving device, a golfing duo with a new take on the traditional tee, and a designer who has flipped the conventional umbrella on its head. The Dragons come face to face with a fellow multimillionaire and the Den is filled with children's teepees.

Inventions galore in the Den - Kelly gets an unusual phone call from outside the Den, a mother-and-daughter duo pitch their children's waterproof products and a trio of break dancers introduce the Dragons to some innovative earphones. Aside from the fun of being serenaded by a group of princesses and having a go on a modern day penny-farthing, will the Dragons feel the need to invest?
