Documentary about the penguins who live on Phillip Island. Unlucky-in-love Rocky finally finds a mate in Jess, whose previous clutch of chicks has died. However, it is very late in the season to be raising chicks before the little penguins' annual moult prevents them going to sea. In the burrow next door, Spike and Tash’s chicks already are preparing to head off on their own. Jess endures a parasite infestation as she waits patiently with her newborn chicks, desperate for Rocky to return to feed them. Wildlife carer Marg Healy gets her most difficult patient yet when a juvenile Australasian gannet is found on the beach and proves more interested in biting her than in eating the fish that will keep him alive. Biologist Andre Chiaradia reveals just what little penguins get up to underwater by attaching a tiny computerised logging device to an unwitting penguin researcher, which will record depth, speed, temperature and even the penguin's angle of dive. When moulting season arrives, the little penguins begin to shed their feathers. Hungry and grumpy, they must wait on shore until their new feathers grow so they are waterproof, weatherproof and able to return to the sea to fish. Narrated by Rolf Harris.
