Uncle Pelfrey
Uncle Pelfrey is an entirely fictitious character who occasionally stalks through T's writing. Created by his younger brother, he is an archetypal kiddie-diddler. By wriggling your fingers a bit like the child catcher in Chitty Chitty Bang Bang and repeating the words 'Uncle Pelfrey' in a really creepy high voice you can reduce your siblings to squealing terror.
