The Power of Kroll

(Series 16, Episodes 17-20)

Summary: Green people who live in a swamp are rather aptly named Swampies, in a familiar story of human colonists viewing the natives as savages.  The Swampies call up their god - the titular Kroll - by jogging on the spot to a techno beat, the humans are essentially harvesting giant squid fart and John Leeson swaps voice duties to show off his ‘staring anxiously and confused at a screen’ skills.  Thankfully, the Swampies live to protest another bypass.  Fun fact: the green dye didn’t come off.

Watch it because: Well, if you want to see what John Leeson looks like…you could probably just do a Google image search.
