Daisy McCarthy is one of the pre-made foreign townies who resides in the tropical Twikkii Island, one of the vacation destination sub-neighborhoods shipped with The Sims 2: Bon Voyage. She can be made playable by befriending and asking her to move in, or by marrying her. Daisy has the same facial structure as fellow townie Tracy Royce. She shares her last name with George, Houston, and Sarah McCarthy, though there isn't any evidence to suggest that they are related.
As far as personality, Daisy is very playful, and somewhat outgoing and nice. But she is somewhat sloppy and lazy. When it comes to Daisy's skill points, she has 7 points in the charisma skill, but she doesn't have any other skills. While she doesn't have any major interests, Daisy's highest interests are Fashion and Sports. Like many other Sims from Twikkii Island, she has three turn ons instead of two, and two turn offs instead of one. Even though Daisy has black hair, her SimDNA in SimPE confirms that her natural hair color is brown. This is further supported as she has brown eyebrows.
