Passage: Willy Puchner became famous with his project "Penguins - Traveling the World". For four years he traveled with his penguins Joe and Sally to the sites of his and our yearning: to the sea and into the desert, to New York, Sydney and Paris, Venice, Tokyo, Honolulu, Rome and Cairo, in order to capture them in photos. There they are now connected forever, lost forever. Before the penguins’ eyes the apparently familiar having been illustrated thousands of times, becomes different and new again.

Question: What were the penguins names?
Joe and Sally
