I've got a story about shinies =D
So, imagine my surprise, as a kid who has played since R/B came out and only found his first (Non-Gyarados) shiny in DIAMOND, when I take a few steps into Oreburgh Cave and BAM! Shiny Geodude. Well, surely, I caught it with absolute care. For bragging rights, I showed my brother my golden Geodude, and he immediately flips out. "HOW COME YOU GET A SHINY?! WHERE DID YOU FIND IT?!" I told him where it was, and I laughed as he frantically grabs his DS and starts up his game, running from his current location in Eterna City(he didn't have fly yet) all the way to Oreburgh Cave. He had such a determined look in his eyes, and it only made me laugh, because he honestly thought he was going to get a shiny from going there.
Sure enough. He found the shiny Geodude. ON THE SAME TILE THAT I DID. Same level, same gender, same NATURE. I couldn't believe it, I mean, you have a better chance of winning the lottery than that... Our shiny Golems sit in our boxes to this day, looking pretty and golden =) And they're the same level too!
