From Nookipedia, the Animal Crossing wiki.
Lucy is a white pig with pink hooves, brown bangs and a rosy pink blush on her cheeks. She is usually seen wearing a Natty shirt, unless she lives in your town, then, of course, she may change her shirt now and again. She has a small brown fringe which goes with her style and has shiny black eyes with two black masiared eyelashes.
Below is a brief description of the normal personality. For more information, click here.
Lucy, having a normal personality, is quite a pleasant villager and loves clothes, especially receiving them from the player. She will ask the player for something every now and again, but she will not be lazy and always challenge the player in order to receive bugs, fish, or furniture. She is polite around everyone, and does not really gossip about other villagers. She rarely goes inside. Usually, when she is outside, she is mostly either catching bugs or carrying a watering can, but most of the time she is carrying a watering can. She always talks about her garden. She loves getting along with people and always has something interesting to say. A lot of villagers say she could be famous one day for her style but does not wish to be one step like famous.
Lucy has an ebony piano, a sewing machine, and two birdcages, or one large table and an odd clock. She also has some clothing in her house, too. She has the shanty wall as her wallpaper and the classic carpet as her flooring. She plays Comrade K.K. if she has a stereo.
