Amis' over-eating has forced him to put on weight. Which would be fine, were it not for the fact that he is the "Chosen One" and everyone knows Chosen Ones cannot be seen to be too pudgy. He is a role model after all. So the Questers take him to see the sorcerer, Dietica, where he is put on a punishing new regime - along with the rest of our noble band of heroes.
But, as ever, danger lurks round every corner in Lower Earth and it is not long until Dietica reveals his true plans for the Questers. And it involves more than just staying away from carbs.

Stephen Mangan as "Sam",
Alistair McGowan as "Lord Darkness",

Kevin Eldon as "Dean/Kreech",
