Four episodes in which Mole makes four wishes, Troll visits Mole, Troll loses a tooth, and night noises scare the pair of friends. The loving, though sometimes challenging friendship between Mole and Troll, is the central theme around which all four short stories in “Night Noises,” revolves.With that constant and reassuring theme in place, each story explores child-sized conflicts with loneliness, selfishness, boo-boos and the fear of the dark (night noises).
