Have you tried it on all of the Barboach? If so, I don't know the answer. However, a location to easily get a Whiscash is in the Slumbering Weald. If you use the fishing rod, it's a 60% chance of getting a Whiscash. As for why Barboach causes the game to crash, I have no clue. It could be a move Barboach knows, perhaps a hacked Barboach, or anything. This is what | Corviknight | is saying. I agree with him
