The Official Annual 2012 is a Moshi Monsters activity book, written by Lauren Holowaty. The annual released in mid 2011, the next one released a year later (hence the word annual). Inside the book, there are puzzles, games, etc and information. Every annual (so far) has come with a secret code, hidden somewhere inside. There are clues to where it is, (e.g. on the fifth line of page 2, etc).
