The complete third series of the animated CITV show based on the best-selling children's books by Francesca Simon. Horrid Henry (voiced by Lizzie Waterworth) is in many ways an average little boy, unable to stay out of trouble and constantly battling against the rules of adults. Few, however, have quite as bad a temper as Horrid Henry and such an unerring ability to find trouble with even their most well-meaning schemes.
