Mutants (radio) refers to an episode of the Mighty Boosh Radio series.
Joey Moose is patrolling through the zoo at night, in contact with Bob Fossil, when he's attacked.
Everyone blames it on the python, but the python has no teeth. Howard and Vince suspect foul play. Howard spies on Fossil, while Joey reveals that he was bitten by a moth with the legs of a hawk.
The heroes, with the injured Joey Moose joining them, convene at the bottom of Wolf Mountain. Fossil's secret laboratory is at the top. Vince forgets to bring rope, so Joey climbs the mountain, carrying Howard, while Vince is forced to stay at the bottom serving tea (or lattes) to a group of old soldiers.
Unfortunately, when they reach the top, Joey falls off, but fortunately for him an old soldier breaks his fall.
