Nope, If you didn't have crazy cat lady the bundle comes with her house, and the iguana skin. For the price (110) is a nice deal. But the down side is you don't get the swamp (which isn't that great).
My opinion about crazy iguana lady is kind of biased. I already had crazy cat lady, and really liked her new skin, cause she looks prehispanic (kind of mayan) , and I have a prehispanic area in my springfield. The problem with the swamp is that doesn't pay out. Also she is not voice, except when battling the monsters (but that might be the iguanas). And she only have two outside tasks and no tasks in the swamp, so theres that. All her taks are in her house or the mayan calendar (without outside animation). However the train iguanas task is kind of funny.
