 Due to how far-fetched and fantastical the stories could become, it is up to the reader whether they found the series frightening or amusing, but the franchise is usually categorised as children's horror.When the series was adapted for the CITV/Nickelodeon cartoons, the book chapters became ten-minute episodes that were narrated by comic actor Nigel Planer, and created by Honeycomb Animation, with author Rix as co-director.The franchise received critical acclaim, noted by the themes of horror surrealism and adult paranoia blended with common children's book absurdity.
