Four years ago, João Pereira de Souza of Brazil made a peculiar lifelong friend.

The 71-year-old retired bricklayer and widower found a magellanic penguin covered in oil near his home in 2011.

He cleaned it off and nursed it back to health. When the penguin was strong enough, de souza brought the bird to the beach but it refused to leave his side.
