Piranha Plant Gal has a dual nature; she appears evil and mean but can be surprisingly kind and sweet. She is also described as perverted and happy. Her most prominent features are her incredibly sharp teeth, capable of biting through almost anything, and a long tongue that drips a purple toxic goop. She is an indiscriminate eater, consuming anything offered to her, edible or not. Her primary motivation is to cause chaos and mischief. She can be flirty, as shown when she calls Guest 'handsome'.
