Moshi Monsters Magazine: Issue 20 is the twentieth issue of the Moshi Monsters Magazine, that was released on the 23rd of August 2012 and was available in shops until the 12th of September 2012.
For an unknown reason, all magazine subscribers received two copies of this magazine. An email was later sent out to subscribers saying this was a mistake and they were free to keep the second magazine, to give to their friends, etc.
