Niffty is hyper, spontaneous, and agile, being very quick on her feet. She is easily entertained, easily distracted, and easily excitable. She hates when there is a mess in any room, and has a fixation on men in general. But, she appears to only like bad boys, having a brief obsession with Sir Pentious, but stopping frustrated that he wasnt a bad boy after he was forgiven. She kicked him in what is meant to be his groin for this. She isn't afraid to get dirty, and enjoys cleaning everyones mess.
