My most annoying moment in Diamond and Pearl, actually in any pokemon game, is that my unskilled older sister always encounters shinies. Being the emptyheaded sister she is, she usually starts over the game with the shinies in them only to find more shinies in her next game. For example: she catches golden magikarp in silver, she catches shiny lotad and spinda in emerald and encounters a shiny swablu and nincada. In fact, just two days ago, she encountered a shiny W unown only to KO it with a critical hit. As for me, I once chained 36 jigglypuffs only to have a jigglypuff end my chain. Also, I caught a shiny tentacool and volbeat. But I traded my volbeat for something else and received a shiny pichu off the GTS. So its:
Me:3
Her:6
Also, its not the fact that she got shinies before me, she got the pokerus before me and didn't even know it!!! Also she had it not once, but twice! Once in ruby and now in emerald. I only have it in Pearl.
Me:1
Her:2
