It was an SOS battle and popped up after the second successful cry for help. I wasn't even trying to get a Golbat let alone a Shiny one. I was in Poni Fields and trying to use the Exp. Share to level up and evolve some Pokémon for the Dex. I had to restrain from screaming in excitement because I was in the car driving down to L.A. I needed Golbat anyway because I skipped catching Zubat since getting one is as easy as catching a cold from a preschool classroom.
