Her red-pink hair is kept into a slightly messy bob cut with swirls on each side, and a single light yellow streak located at the top. Her mouth has sharp light pale yellow teeth inside and black lips, and small hot-pink dots on each of the corners. Niffty's attire is that of a black neckerchief around her neck, and a 1950s red-pink maid dress under a white apron with three hot-pink dripping splotches. She also wears long black gloves which covers most of her hands and arms, along with matching-colored tights. Niffty is hyper, spontaneous, and agile, being very quick on her feet. She is easily entertained, easily distracted, and easily excitable. She dislikes when there is a mess in any room, and has a fixation on men in general. However, she appears to only like "bad boys", including a brief obsession with Sir Pentious. This ends in her kicking him in frustration after he apologizes and decides to seek redemption at the hotel. She isn't afraid to get dirty, and enjoys cleaning everyone's messes with a gleeful, yet creepy charm. Niffty has an extreme case of obsessive compulsive disorder, constantly cleaning the Hotel and obsession with ridding any bugs she sees to the point she would bring out a knife just to kill them. She is shown to enjoy violence, as she was very ecstatic to be thrown into a warzone as part of Vaggie's trust training, Abilities, Fire resistance - When Alastor summoned Niffty from the Hotel's fireplace.* “hmm killing bugs are fun.”
