[Episode] "Let's Take a Quiz" [Patches] Broadcasting Patch [Notes] 
Earned by helping Phineas and Ferb produce their game show. Isabella was taught how to fix and work the camera and helped get the game show in order. Isabella is most likely the only one who earned this patch, though we see Gretchen applying makeup and Holly and Ginger Hirano were working the cameras.
