when speaking and starts making dog noises, the latter of which, he claims, helps to relieve stress. Used to be an estate agent prior to the death of his wife and loss of his children, the trauma of which sent him mad. Since then, his greatest ambition is to be the furthest travelled of all Rottentrolls, to which end he attempted to build an airship and later a rocket. Four attempts were made to build a rocket; all but the third (upon which Sigsworthy forgot to embark) were met with failure. On the fourth attempt, he crashed underground and awoke to the sound of drumming on his rocket; looking for the source of the noise, he realized that he was reunited with his sons. Ripley and Scuff – A pair of young Rottentrolls, sons of Sigsworthy Crags. They appear in Series 4, and in their own spin off series, Ripley and Scuff. They seemed to have inherited their father's mental instability, or at least his tendency to make dog noises. They also communicate through making drumming noises. Loupscar - Kettlewell's son and Strid's biological brother. He was only seen via flashback in the episode "The Stake Out" where Penyghent tells Princess Kate how she grew up with him. She also tells her that he had been eaten by the Barguest. Their names are all taken from places in Yorkshire. Tim Firth said about how he named the Rottentrolls: "I put a compass in the OS map of the area, centred on Troller's Ghyll and drew a circle of about 5 cm radius. I then harvested the strangest-sounding villages and geographical features. These then seemed to suggest, bizarrely, the colours of various mad characters. Yockenthwaite would clearly be an idiot because it had a 'k' in it. Sigsworthy Crags would clearly be off his trolley, but older. Penyghent would be female... and so on. I wish every assembly of characters was that easy." The voices of the Rottentrolls were provided, in the first series, by John Thomson, Phil Cornwell and Rebecca Front. In later series Ronni Ancona replaced Rebecca Front. Other creatures The Barguest is a menacing creature that lives in the valley and terrifies the Rottentrolls. Commander Harris is a sheep who used to be an army mascot – he always has a tale from his old army days to tell. He too lives in the valley. Commander Harris is
