Roger and the Rottentrolls started life as a book and audio tape, written by Tim Firth, commissioned by EMI and W.H. Smith, and produced by Robert Howes and The Childrens Company, intended as a 'spooky story' for children, part of a series of over 30 titles.Tim's dad, Gordon, who had originally invented the characters, drew the designs for all the characters from which the puppets were made.The series followed the adventures of Roger Beckett (aged 10½... sorry, 10¾) in Troller's Ghyll, "where the rocks are all slightly mad"; after crashing his bike in the valley, it is soon discovered that he is The Chosen One and he was crowned King of the Rottentrolls. Cue four seasons of a pretty damn funny mix of live-action and puppetry. It won a BAFTA.
Examples of tropes:
Appropriated Appellation: Played for laughs; the Rottentrolls take their name from an incident in which their ancestors ruined one of Merlin's spells, causing Merlin to declare angrily, "Oh, those rotten trolls have messed it all up!"
Blatant Lies: The Rottentroll National Anthem, which must be heard to be believed:
Bungling Inventor: Sigsworthy Crags. Out of four rockets he tried to build for interstellar travel, only the third one worked... and Sigsworthy forgot to embark.
Call Back: At the end of the pilot, Roger tells the Narrator that he's never coming back to Troller's Ghyll, with the Narrator calmly assuring the viewer that he will, or his name isn't... Narrator. The second episode comes around, Roger's back, with Narrator immediately calling him out on his prior statement; Roger says he's just passing, the Narrator calls him out on that as well...
Closer to Earth: Pretty much all the female characters are shown to be at least a little bit brighter than the boys, with Penyghent pretty much being the Only Sane Rottentroll. Not used too badly, what with Roger and Aysgarth balancing things out as a pretty down-to-earth kid and a wise old Rottentroll respectively... until season 3, which introduced Kate, Roger's sister who pretty much ended up being a Canon Sue from day one, with her and Penyghent being The First Two Faces Of Eve pretty much every episode.
God Guise: All one needs to do to become a God-king of the trolls is to stand in the middle of an abandoned quarry and yell "Roger was here", as the trolls had an ancient document (graffiti on the wall of the quarry) that said those exact words.
Location Theme Naming: Pen-y-ghent is a hill in Yorkshire, Yockenthwaite is a village in Yorkshire... and so on. Troller's Ghyll really exists, though it's a different valley to the one they filmed in.
