Caryl Gray is a hidden downtownie in The Sims 2: Nightlife. She can't be made playable without cheats. Unlike other downtownies, Caryl does not appear in-game because she is not placed in any of the SimBins when viewing SimPE. However, with SimPE, it is possible to add her to one. She has no turn ons and offs, nor does she have any interests or skill points.
As a hidden downtownie, Caryl does not have a randomized name. Cheryl Miller also has this case. According to her SimDNA in SimPE, her hair was blonde before it turned grey. Like most downtownies in The Sims 2, Caryl has a customized facial structure. She uses a customized version of the 7th Maxis face template in Create a Sim.
