Treasure Trove Trials: Shocks, Crocs and Rox is/was an upcoming book series, supposedly additional fiction to enrich and expand the world of Moshi Monsters, such as the Monstrous Biographies and Music Island books do. The first installment is called "new series fiction 1" but this seems to be more of a code than a first parter title. Publisher Puffin Books claims the release date to have been "July 3rd 2014" while all other sources claim it to have been "December 3rd 2015".
