This book tells the story of Peek Platypus, who is having a peaceful evening swim in the river. Suddenly he sees a strange thing swishing through the water towards him and, before he knows it, he is being pulled out of the river. The Uprights, or humans, he meets think he is a valuable furry fish and decide to sell him to the nearby explorers, but they do not reckon on Denny Dingo who decides to rescue Peek. Will his plan succeed? (Libraries Australia).
