The Dragons catch up with some of the most unforgettable entrepreneurs from the season.

In this special encore presentation of the premiere episode of Dragons' Den, an exercise machine has the Dragons lacking motivation.

A pitch for a hi-tech billboard and an entrepreneur tries to convince the Dragons there's big business in custom-made pet products.

A hopeful entrepreneur enters the Den with cheeky underwear and things heat up in the Den when an entrepreneur pitches a new spin on cook stoves.

The show begins on a high note with an idea for amusement park rides; an entrepreneur tries to sell the Dragons on a special brand of bottled water.

Two recent MBA graduates believe they have the next big business idea; a "Ski Limo" pitch promises to chauffeur non-skiers down the slopes.

The Dragons are presented with a business idea for self-help "Mystical Cards" and a pair of super binoculars claim to be able to see through almost anything.

An exercise machine has the Dragons lacking motivation; a tidal energy bridge gets a dose of reality; and two entrepreneurs enter the Den to pitch their magnetic gift card idea.
