The real brilliance of this series is the format of the book, which is similar to Smith's other series, Claude in the City. The words are large and well spaced on the page, illustrations abound, and the orange and black color scheme provides added interest. The illustrations are as goofy as the characters they portray; Professor Stout-Girdle, Gordon the pigeon, and the evil Mesmero, whose identity is a bit of a surprise!
For readers who revel in Roald Dahl's unlikely British tales accompanied by Quentin Blake's exuberant line drawings, Mr. Penguin is a great fit. In a world where spiders write notes to communicate and pigeons are able to fly their friends around, there's no doubt that a motivated (if not very bright) penguin can save the world for certain destruction.
