My first shiny was in FireRed. I was travelling through Viridian Forest, and got into a battle. I had found a Caterpie. But, y'know what? It was golden, and the shiny animation made it look like it had gotten hit by a shooting star. I caught it immediatly, because I knew it was something special. Later that day, my friend came over and was like, "Ohmygodyoucaughtashinyohmygodyou'resoluckyohmygod." I had no idea what he was talking about, but now I do. I traded it for a shiny Eevee with perfect IVs, though.
