'Waddle!' adds touches of color to the images and integrates it into the text. The prancing pig is pink, the leaping dolphin is blue, the slithering snake yellow. The Scanimation itself is also more lifelike, as the author continues to refine his patented Scanimation process, resulting in a more fluid, realistic motion. And one more thing - 'Waddle!' has a surprise ending. Something else to grab the reader - literally.
