Rattus Rattus returns to investigate historic events and strange facts through a mix of live action sketches and animation. This series sees the return of Mr Death as he presides over some of the most stupid deaths in history and there are a whole new bunch of memorable sing-a-long-if-you-dare songs from 'Ain't Stayin' Alive' by the Aztec priests to a Roundheads and Cavaliers West Side Story song and dance spectacular.
