"Blue's Room" (10 a.m., Nickelodeon): The blue hound and her little brother, Sprinkles, take preschool viewers on new adventures in this weekly 10-episode series that's a spinoff of "Blue's Clues." In this new series, based on previously aired specials, Blue is a puppet that speaks to viewers. Set in an interactive playroom, each episode is an imaginary play date, with Blue, Sprinkles and their human, Joe, leading the way. The series opens with a pretend visit to Old McDonald's farm, where the dogs collect the chickens' eggs, feed a pig and horse, and learn to milk a cow.
