The hosts return to Phineas and Ferb Season 3 to discuss two episodes that aired as part of a 2012 premiere event. Tri Stone Area takes the gang back to the Stone Age where they invent the wheel and speak only in caveman dialect, highlighted by a clever photo-animated segment featuring creators Dan Povenmire and Jeff "Swampy" Marsh explaining the episode. Doof Dynasty sets the story in feudal China with a martial arts training montage, though the hosts note concerns about cultural representation. Both episodes break from typical series formula in different ways.
