Cable is serving up the visual equivalent of comfort foods this week: animated series based on cherished children’s books with a Gallic accent. The Family Channel has Madeline in London (Thurs., Nov. 28, 7:30 P.M. ET), the sixth song-filled half-hour special taken from Ludwig Bemelmans’s charming stories about Madeline, the plucky Parisian schoolgirl. (More are planned.) That same day, Babar will bob along for the first time in the Macy’s Thanksgiving Day Parade (NBC, 9 A.M. ET). The King of the Elephants also has his own show, Babar, on HBO daily (8 A.M. ET), where he rules benignly over Celesteville in half hours true to the books by Jean and Laurent de Brunhoff. For a slightly more mature audience, HBO recently introduced The Adventures of Tintin, based on the internationally popular stories by the Belgian author Hergé. In this week’s episode, “The Cigars of the Pharaoh” (Thanksgiving night, 7 P.M. ET), cub reporter Tintin, who’s sort of a cross between the Thin Man and the comic-book character Archie Andrews, travels to Egypt. All three cartoons are anodyne asylums from the crazy, grown-up world.
