This animated documentary set on an Antarctic island features a colony of happy penguins as they go about their mating rituals and day-to-day habits. One of them tries to impress his girlfriend by catching fish, which she does in fact eat and swallow. But this, being a Disney cartoon, does not mean the fish is slowly and painfully dissolved in her stomach acid, so the fish escapes whole and she goes off to find her own lunch, leaving the male jilted.
He tries to warn her of an approaching shark, though I am sure than no sharks stalk Antarctic waters, but I could be wrong. The male eventually rescues her by bonking it on the nose with a stick - fine method of dispatching a squalus if there ever was one. Even after being swallowed by the shark the male, and other little fish do manage to escape.
Underlying message of cartoon: no animals are carnivorous.
