My friend Dakota found and caught a shiny purrloin.How can I get one for myself?
Still the standard 1/8192 chance for any Pokemon. Unless you use the masuda method or shiny charm. Either way you still dont have high chanses of getting one.
Some ways:
Obviously, your chances are extremely low - your friend was lucky to find that Purrloin.
Go to Route 19 or 20 and hope for the best, that is all you can do. You can also maybe use Masuda or maybe Oval or Shiny I can not remember, charm.
