Later series were written partially by Mark Haddon, author of The Curious Incident of the Dog in the Night-time.
The characters speak directly to the camera, commenting on their lives while dream-like images are projected behind.
Her cousin, Georgina, who later takes her place in the cast, has similar problems, but her character is more rebellious and manipulative.
Nicknamed "Wart", Arthur (played by Peter Kelly) is defined by his obsession with wildlife.
He is constantly seen with dirt on his clothes and skin, presumably from where he has been digging around looking for minibeasts, and he seems impervious to this.
Played by Philip Bird and Annette Ekblom, Mr. and Mrs. Wild's characters do not take centre stage.
