Rebecka Garth is one of the pre-made downtownies in The Sims 2: Nightlife. She can be made playable by befriending and asking her to move in, or by marrying her. Rebecka is employed in the Slacker career at the start of the game, and she is mainly interested in Food, Paranormal, Fashion, and Work.
Rebecka is a slob, one of the few special downtownies. As a slob, she has no neat or active personality points, and has autonomous reactions, such as farting and burping, that other Sims either do not display or rarely display. Rebecka's name is randomized when Downtown is generated. The name "Rebecka Garth" is only referenced in the game files.
Her lifetime want to have 100 first dates is unique, as it is not available to CAS or born in-game Sims, and is probably part of the code for the default Downtown template. This want can be satisfied by moving her in and having other playable Sims date her in a large neighborhood.
