What are townies in the sims 2 pets for ps2?

Well, "townie" Sims are those which are roughly equivalent to playable Sims, having jobs and other characteristics of a playable Sim, except they do not live on an actual lot. They visit the Community and Residential lots and can be interacted with just like any other Sim. With very few exceptions, any Townie may become a playable Sim if he or she accepts an invitation to move in, to be joined, or to be married.
