The programme is centred around the daily adventures of
Barney Harwood, his pet bear
Nev, his koala friend Crazy Keith and the caretaker of the trio's flat, Andy Prank. Nev and Barney originally appeared together on Sunday morning children's programme
Smile which ended in 2007. The programme features the voices of Ross Mullan as Nev and Simon Buckley as Keith, with actress
Bella Emberg playing the role of Aunt Barbara. A series of twenty-six episodes was commissioned by the
BBC in March 2007, after a trailer for the proposed series being uploaded to YouTube received over 1 million hits. Following successful ratings, a second series of twenty-six episodes followed in December 2008. Both series were originally broadcast on
BBC One, before being repeated in an early morning slot on
BBC Two. In August 2009, a third series of thirteen episodes was filmed. These episodes began airing from 7 December 2009, this time on the
CBBC Channel, before later being repeated on
BBC One. In July 2010, a fourth series of thirteen episodes was filmed. These episodes began airing from 6 October 2010. The series concluded on 21 December 2010, and thus far, no further episodes have been filmed. Repeats continued to air until March 2016 on CBBC. ==Synopsis==
