Duchess- A "high-maintenance" pedigree friend who is pompous, ugly, rude, arrogant, selfish, self-centered, and lazy up to the points she orders Frankie to open her eyelids for her first thing in the morning. She considers herself superior to all the other imaginary friends, is extremely negative towards everyone, and never says anything nice (despite this, she has helped someone in four episodes, albeit for selfish reasons). Whenever Duchess turns on the spot, her entire body pivots like a sheet of paper being flipped, revealing that she is two-dimensional (however, in the pilot movie "House of Bloos", she was not two-dimensional). Her full name is "Her Royal Duchess Diamond Persnickety the First, Last, and Only". She is voiced by Grey DeLisle.
