The development of the series began in 2013, when Blue Zoo Animation Studio collaborated with Bristol-based stop-motion entertainment company Aardman Animations (who previously made CGI-animated films and series like Planet Sketch, Flushed Away and Arthur Christmas) to develop an CGI-animated series created by Sally Hunter entitled Digby Dragon, with Blue Zoo producing and handling animation for the series as Nickelodeon UK had commissioned the series to air on its Nick Jr. channel while Aardman handled worldwide distribution to the series.^[4][5]
