When foxes discovered little penguins on a small Australian island, they nearly wiped the colony out. But a farmer came up with a novel way to protect the birds - and the story has been made into a hit film.
As a premise for a film, think Lassie meets Babe meets Pingu. What's not to like?
Middle Island, a beautiful, rugged and windswept outcrop off the coast of southern Victoria is home to a colony of the world's smallest penguins.
Originally known as fairy penguins, before some pen-pusher deemed that politically incorrect, they've now been given the far more dreary sounding title of little penguins.
To be fair, they are just that - little, standing at 30 to 40cm tall.
There used to be hundreds of them on Middle Island - but that was before the foxes got to them.
