'Can you waddle like a penguin with a little orange beak? Wiggle-wiggle-waggle! Squeak-squeak-squeak!' 'Can you stomp like an elephant with a big old purple trunk? Boom-boom-badoom! Crunch-crunch-crunch!' All animals move, but how they move - whether they waddle, stomp, or fly, is a source of endless fascination for children. "Waddle!", like its predecessors "Gallop!" and "Swing!", uses 'scanimation' technology to simulate movement by the simple turning of a page. Unlike the previous two books, though, "Waddle!" also introduces colour into the text and illustrations, so children are learning two key preschool concepts at once: colours and motion. Leaping green frogs, flapping red hummingbirds, slithering yellow snakes, these animals are truly amazing to see.
