When unexpected debris from outer space crashes onto their peaceful planet, the Clangers explore these strange arrivals with curiosity and wonder. Today, Iron Chicken radios Tiny Clanger warning her egg will crash on the planet. Acting swiftly, the Clangers catch the egg with their tablecloth and wrap it up to keep it warm.
Relieved to see her egg safe, the Iron Chicken comes down to find a cozy crater to put the egg in and wait for it to hatch. Unexpectedly, the egg falls through the crater into the caves of the Soup Dragon. It tumbles and falls over a cliff in the cave. The Clangers quickly use a fishing pole to grab the iron egg.
The Clangers reel in the egg shell, but the delightful chick has already hatched. Bursting with hunger the Clangers quickly discover what Iron Chick likes to eat: delicious metal nuts, bolts, and screws. With the help of friends, the Iron Chicken's baby is safe.
