Most unlikely that she would return....was more than 10 years ago when she left 
The only one that knew her was TIB, which is long gone too, so there is no way to contact her.
I recall that she had a myspace page ages ago; and a fb account for a bit of time; before getting tired of tickling fans bothering her (it is not really the best thing to get posts about tickling stuff on your page, where everyone can see it LOL).
I would love to see a mature PJ come back, but most likely the chances are close to 0
Help me to make the world better.....let's tickle all the girls ^_^
