Clangers (2015)

Space Tangle (1x11)

:

Small has invited the Iron Chicken to a picnic. But the Iron Chicken is late, and when Small looks through his telescope, he can see why. The Iron Chicken is trapped by a load of junk metal which has got caught in orbit around her nest. Major comes up with a clever solution to free the nest of the orbiting metal, but in doing so it seems he may have inadvertently lost the Iron Chicken.
