Round the Twist  Round the Twist is an Australian children's fantasy television program about three children and their widowed father who live in a lighthouse in the fictional coastal town of Port Niranda and become involved in many bizarre magical adventures. Four series were made during the show's 11-year run. The first two series were based on fantasy stories written by author Paul Jennings; the latter two were based on a variety of authors' work. The first series was filmed in 1989, and first aired in 1990. A second series, with many roles re-cast, was filmed in 1992 and first aired in 1993. A third series, again re-cast, was made in 2000, followed by a fourth (with some roles again re-cast) in 2001. The show's theme song, with the lyrics "Have you ever... ever felt like this?" was sung by Tamsin West, who played the lead female role of Linda Twist in the first series. It borrowed lines from nursery rhymes such as "There Was an Old Lady Who Swallowed a Fly", "Humpty Dumpty" and "Rain Rain Go Away". The song was used in a series of Halloween television adverts by United Kingdom supermarket chain Sainsbury's in 2018. Making a show about children which spanned more than a decade meant many changes in actors were required, as the child actors became too old for their parts. Overall, three sets of children (the Twists, the Gribbles and Fiona) were cast. Additionally, most of the major adult roles were recast at least once: overall, there were two Tonys, two Nells, three Fays, two Mr Snappers, two Harold Gribbles, and three Matron Gribbles across the series' run. The show revolves around the four members of the Twist family:  Characters who appear briefly in each episode of a series include:  Four series of "Round the Twist" have been made, each comprising thirteen episodes. Although each episode has a self-contained plot each series has a recurring theme, usually an object or character which appears briefly in every episode. This gradually develops the theme until the final episode of each series in which it is explained and resolved. The Twist family also have frequent conflicts with a ruthless local businessman, Harold Gribble, and his family. Typically, Gribble seeks to remove the Twists from the lighthouse in order to more profitably use it as a tourist attraction for Port Niranda. This is a continuous feature of the first series, and a recurring feature of the third and fourth series.
