Wallace, owner of the Rainbow Factory and the CEO of the new WHtechs, decided to create a talking system to improve reality called WHtechs (Welcome Home Technology). Each robot, Julie, Eddie, Howdy, Barnaby, Poppy, Frank, and most importantly, Wally (or W.DT02 or Wallace), holds an important role and features in technology and the human world.

Wallace decided to bring his son Walden to the factory to meet the robots and to be his little assistant for the day.
