The Official Annual 2013 is a Moshi Monsters book, distributed by Penguin books. 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.) This particular annual has been dedicated to Snuffy Hookums as she re-explores Monstro City after being lost for 1,874 days in search of Buster's Ranch to re-unite with her mentor Buster Bumblechops.
