Krahn's anteaters, comically ugly in thor human postures, constitute one of those large, unorthodox picture book families that always seem to have more fun. Father Harry Minus plays his flute at breakfast and Mother Mary invents devices. When she uses the car battery for her latest invention, Electrisnake Number One, Harry can't drive the eight children to school. So Mary dons a hard hat with her housecoat and packs Thirdly, Fourthem, Sevenor, Eightah, and the rest into the peculiar train of egg-shaped cars which she drives over rooftops and down the schoolyard steps to be met by cheers and a professional photographer. And all eight little Minuses are ""happy and proud to be part of the most fabulous family--Family Minus."" What, if anything, they are minus Krahn doesn't say--but you might get the feeling you've missed something. Offbeat foolery.
