Waddley, a Macaroni penguin who lives in Antarctica, has always dreamed of seeing the world! He gets his chance when he meets Lexi and Sam, two young visitors traveling with their parents, and secretly follows them back onto their ship. Delighted to see him, they tell Waddley he's come to the right place: the ship is on a round-the-world cruise and the next stop is Australia! His dream come true, Waddley cruises into Sydney Harbor as the sky blazes with Australia Day fireworks, plays the yidaki and races around the massive rock natives call Uluru, swims with giant fish in the Great Barrier Reef, and finds himself upside down in a kangaroo's pouch, as he - and readers - learn all about the country down under.
