Let me introduce you to Dindim, a South American Magellanic penguin.  He swims 5,000 miles every year to see his special friend.

In 2011 Joao Pereira de Souza found Dindim, covered in oil and close to death.  For 11 months Souza nursed the penguin back to health.  Dindim has now been visiting his friend every year for the past four years.  Souza, a retired bricklayer and fisherman, lives in Brazil.
