From The Guardian:

Brazilian television channel TV Globo reports on Dindim the penguin, who travels to a small island near Rio de Janeiro every year to be reunited with a man who saved his life after finding him covered in oil and struggling to survive. João Pereira de Souza, 71, a retired bricklayer, found the South American magellanic penguin in 2011 and nursed him back to health.
