Walden, 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.

Walden decided to bring two of his robots to a grocery store with him, Wally and Julie (they're best friends). The WHtechs is still fairly new and people yet still need to see the creations.
