"Ah yes, the Master Safari Ball. You see sir, one of the problems we noticed in the Safari zone was that trainers had difficulty capturing the pokemon without weakening it first. While this is good for the population of pokemon within the park, it made trainers that caught no pokemon not want to return. To correct this, we created a master ball, so our customers can at least catch one pokemon, guaranteed." The receptionist explained warmly. "It did work, did it not? If it didn't, can you describe how the ball broke? Or do you perhaps have the pieces?" She asked, tilting her head.
