Gadzooks writes things on his pad that come to him and sends this to David telepathically. He is David's main asset when it comes to writing Snigger and the Nutbeast, which originally started out as a birthday present for Lucy, and later David's second book, White Fire, which is about polar bears. Gadzooks helps David with plot ideas and comes up with (or discovers the real) names for many of his characters, including Snigger, Caractacus the crow, Ingavar, and Thoran.
