Moshling Sets are a feature of the Moshling Zoo in Moshi Monsters. Sets include four Moshlings, each of whom is unique and matches the theme of the set, e.g. Oddie is a doughnut and is in the Foodies set. Currently, there are 53 known sets, but only 47 are released. Some Moshlings sets are currently 'incompletable' because the Moshlings (or Moshling) in the set are unreleased, although once a set is released or confirmed, it may have an SWF file where players will be able to see its design.
