This charming family adventure is a story of smelly monsters, dangerous humans and what happens when the things that go bump in the night move in next door. We follow Fungus as he goes through his paces, menacing and frightening those on the surface (the 'Dry Cleaners') as Bogeymen are meant to do and have always done. Unlike other Bogeyman, Fungus has to navigate his world colliding with our above ground world. Over the course of the four episodes, Fungus and his son Mould journey through the maze of life on the surface, while also discovering the highs and lows of their father and son relationship.
