[0:04]But one challenge stops them in their tracks.
[0:10]A giant petrol.
[0:16]They try to flee but running isn't an emperor's strong point. A slip is all the petrol needs.
[0:30]The chick is grabbed by his neck feathers. But the down just falls away.
[0:41]They form a defensive circle and prepare to stand their ground. Despite their chick-like appearance, they are close to a meter tall. Quite a size, even for a giant petrol. The chick towers to full height, protecting those behind.
[1:07]His defiance buys time.
[1:14]It's a standoff.
[1:21]Then, as if from nowhere, an Adélie, the feistiest penguin in the world.
[1:32]He fearlessly puts himself between the chicks and the petrol.
[1:39]Even petrols don't mess with Adélies.
[1:49]That plucky rescuer accompanies the chicks to the sea.
