sentences:  The final episode was to have the Doctor defeating the Delc leader by hitting it out into space with a golf club, and indeed Lucarotti planned to give each episode a frivolous title, citing "Puffball" as the title of an early episode and "Golfball" as the title of the final episode.When the draft scripts arrived from his home in Corsica, Holmes and Hinchcliffe felt they were far too ambitious and complicated to realise on the programme's budget and Lucarotti had over-conceptualised the story, which meant that it was inappropriate for the viewers.It was replaced by a different story with the same title by Robert Holmes, which shared only the setting with the previous version.
