Elmer and the White BearElmer and the White Bear

When a mysterious white bear appears in the jungle, Elmer and Wilbur are eager to hear his story. He has come all the way from the North Pole on a floating scrap of ice, and now he can't find his way home. Luckily, Elmer and Wilbur have an idea! But what caused the white bear's icy home to melt in the first place? That's a much more puzzling question.
