Mook is a children's book featuring a two-eyed furry monster. Mook transforms into various shapes and personas, based on the wordplay on its name. The book is intended to expand children's (and adults') imagination, by illustrating the malleable nature of our language, and the malleable nature of our identities. From Mookhamad Ali to Mooooooook to Mooklear Explosion, the book introduces various forms of wordplay and coinage, accompanied by original hand-drawn illustration. The book leaves pages at the end for the reader to invent, name, and draw their own Mook. Mook is part of a series. Mook's friends each have their own book in which they transform in unique and delightful ways.
