I agree the natural means method would be more realistic, imo.
@ Daughter of Leo - the characters you have there thus far seem to be a decent start. Consider establishing why Quinn became a druggie in your story, I suggest, and also how Mr Fuji can manage to send people to potentially other regions to bury Pokemon (is there a charity, or a network of volunteers, or..?) as those were questions that came to mind for me. The Berry juice idea is neat I feel, and certainly there are a number of different berries out there to take advantage of with that idea as well perhaps, if you so choose. Then you just need to integrate those characters into the plot you have planned. (For the record femslash is not my thing so I doubt I'll have much advice to give in regards to that =p).
