Penny Fitzgerald was a native of the Cartoon Network Country. She was an antlered peanut who is in Miss Simian's class at Elmore Junior High (Latin: Elmore Junior Maximum). Gumball and Penny have massive crushes on each other, but the two of them struggle to express their feelings.
Penny is an anthropomorphic peanut. Like the rest of her family, she has a set of antlers growing out of her head. Her body is a sort of shell, although what she looks like underneath this shell is not currently known. Since she has a shell, it is covered in various holes through which her arms, legs and antlers stick out.
Starting in season 2 of the TAWOG (and in film series), the design of Penny's shell has been altered. Previously, it was straighter and shaped more like her father's shell, but now it is curved to resemble her sister's and her mother's. Her antlers are also darker.
Penny does not normally wear much clothing aside from a pair of orange sneakers and some red and white arm bands.
Penny is very nice and friendly. She sticks up for her friends often, implying she has a strong sense of integrity.
She is one of the only people to understand Gumball, whom she has a crush on. The feeling is mutual, but neither of them have ever had a chance to properly express their feelings, despite that its clearly evident.
She has represented independent signs of getting annoyed on occasion, like becoming angered (even resorting to deception) to her father in the episode "The Knights" when he forbid her from seeing The Wattersons, and tiring of the conflict between Gumball and Tobias in the same episode. But she is exceedingly grateful and ecstatic when Gumball saves her from accidentally getting hit by her father's vehicle, and relieved when she realizes her father Mr. Fitzgerald is okay as well-showing that she is self-sufficiently forgiving and caring.
