First non-Gyarados shiny was a Girafarig back in Gold. I noticed the sparkles and didn't quite know what it meant. It was the first Girafarig I'd seen so I wanted to catch it anyway and was successful. I later confirmed its shiny status, but I hardly used it.
I've encountered/caught 3 wild shinies since then, all on my HeartGold file.
