 contains twenty-six episodes which first aired between 3 September 1988 and 25 February 1989.Series 5 is longer than any of the other series, and contains almost a third of the total number of episodes.The series was made with a view to airing the show in the US, so episodes were shortened to 25 minutes rather than 30 minutes to allow for commercial breaks; and twenty-six episodes were commissioned to tie in with the American tradition of having "seasons", rather than the typical British "series" of six to eight episodes.
