Old Man McGucket is the writer of the books and/or he has Book 1. He knows about the cursed wax figures ("Are the Wax Figures alive, and, follow-up question - will we survive the Wax-Man uprising?"). He knew about the Trickester too, he was pretending to not listen, as he knew about that. Plus, he designed all those monsters he built off REAL phenomenon. The reason he is a "local cook" is because he is (one of) the only one who knew about the mysterious happenings.
