Demi Louie is one of the pre-made NPC Arts and Crafts Hobby instructors who comes from Hobbies, the secret sub-neighborhood introduced with The Sims 2: FreeTime. The other two arts and crafts hobby instructors are Cassidy Monif and Trevor Ngai. She appears in every neighborhood once FreeTime has been installed. Demi can be made playable by befriending and asking her to move in, or by marrying her.
She has long curly blonde hair, green eyes, and medium skin. Demi is a Popularity Sim with the Leo zodiac sign. As far as personality, she is quite extremely neat. But Demi is somewhat sloppy, lazy, and serious, and quite grouchy. She is mostly interested in Weather, Politics, and Sports. Demi has the same facial structure as Holly Andersen.
Even though her default head-shot depicts her with long curly hair, and wearing a golden dress, when Demi is first spawned in-game, she will have short hair, and a somewhat Bohemian styled outfit. However Demi will still retain the hairstyle in her default thumbnail, for most outfits besides everyday. Her pre-destined hobby is Sports.
