Flaky is a red porcupine whose spikes have white flakes that resemble dandruff. Flaky's gender is listed as being unknown, but the creators commonly refer to the character as female. She was intended to be a female, but lacks physical qualities that other female characters share, particularly eyelashes.
Flaky has the rather identifiable personality of being a shy and timid character and tends to throw up in tense situations. Additionally, when hanging around with other characters, she is often forcefully dragged into situations that led to her demise, despite the warnings about possible danger that may occur. Flaky's deaths tend to involve her either getting skinned or eaten.
Flaky is not only overly cautious, but also one of the more intelligent and kindest characters of the series. However, she has, on occasion, been seen as somewhat unstable. She is also allergic to peanuts, causing her face to be covered in hives, her lips to swell up, and her entire body to inflate like a balloon.
