Frankie has pale-white skin and red hair that she generally ties into a spiky ponytail. According to her driver’s license, her eyes are green. She wears a white baby tee, exposing her navel, with red trim on the collar and sleeve ends as well as minimalistic Powerpuff Girls symbols on the front depicting Bubbles, Blossom and Buttercup, a long-sleeved hooded green jacket, a dark purple miniskirt, golden orange socks and blue and white trainers. She also wears a purple hair clip, a thin black choker around her neck and has multiple piercings in her ears. Frankie Foster is based on the show's creator Craig McCracken's wife, Lauren Faust. She is the funny, friendly, hard-working, kind, capable, easy-going, but still short-tempered granddaughter of Madame Foster. According to her driver's license, she was born on July 25, 1984, is 5-08 ft tall, and weighs 127 pounds and has green eyes (proven in "Destination Imagination", when one of her eyes peeks through a window of the Foster's model). However, there is a timeline glitch: In "The Trouble With Scribbles", Mr. Herriman said she had let the Scribbles out in fall 1984, and she appears to be 2-4 years old in the flashback (or, at least where she's old enough to talk). Frankie has lived at Foster's nearly her entire life, having moved there in her early childhood. It is unclear what happened to her parents, though Frankie mentions during "Who Let the Dogs In?" that they helped her conquer her fear of ghosts when she was a child. As she grew into her teenage years, Frankie, who had spent her life in the company of imaginary friends, soon took on the role of taking care of pretty much everything at Foster's. She was placed in charge of cooking, cleaning the house, doing the laundry, running fundraisers, driving the house residents around in the multicolored bus, and otherwise taking care of her grandmother's foster friends in every way. She occasionally shows signs of stress as a result of her many duties, though its primary source seems to be Herriman's constant over-enforcing of the house rules and that he forever expects her to work harder, despite her full workload.
