Trout tickling is also mentioned in later works: Mark Twain wrote about catching catfish in a similar manner while mentioning that salmon and certain other species can also be lured and caught in this way. Arthur Ransome's novel "The Picts and the Martyrs" contains a detailed description of the technique by a young boy from the English Lake District. It is also described as a poaching method in Roald Dahl's classic novel "Danny, the Champion of the World", in Linda Buckley-Archer's science fiction novel "Gideon the Cutpurse", in Robert A. Heinlein's fantasy novel "Glory Road", and in the video game "Theme Hospital" as a hobby of many of the staff for hire. Terry Pratchett's 2003 young adult novel "The Wee Free Men" opens with young Tiffany Aching amusing herself by tickling trout.
