Journal 3

3 is a book that Dipper finds in a hollow tree. It has information on all the strange creatures and happenings in Gravity Falls. Dipper guessed that Norman was a zombie after reading from the book. The book will probably be expanded as the episodes come out. The book appears to contain information on monsters, codes, and maps. It is written by a person who took six years to discover the secrets of Gravity Falls. He then figured out he was being watched and hid the book, lest "he" finds it. Given that the page of the book say "Vol. 3," it is most likely part of a series and the sequel to 2.
