I must be pretty lucky. I ran into a shiny tentnacool after about 70 hours of play in my sapphire. It's a tentnacruel now. I also have a shiny ditto and medopod(never trained it) back in my Gold. The only shiny that I've ran into and managed to get way was a dang oddish. Oh, I have a shiny gyaraydos, too. XD
