J'adore Monsieur Mustard! Such a lovable, braggadocious souris and main character. The storytelling is innovative and fresh and I loved the specificity of the characters' quirks. The illustrations are exquisite (how can a page that is mostly falling coins look so nice?!) and there is such a sense of innovation and play on every page. And of course I loved all the comic book pages. What a talent Charley is! -- Sheena Dempsey
