Because the other one was from 2004. o.O
This is the official place to chat about anything to do with Shiny Pokémon! Which ones you own, how you got them, if you've been hunting for any or are soft-resetting for them - anything you want!
To start off, I myself have caught three Shinies, each from a different game.
Totodile I got as a starter in my Silver version (at first thought it was a glitch and almost deleted it!), I found a Weepinbell while playing my cousin's SIlver, then found a Shiny Geodude in Crystal.
I had been soft-resetting for Shiny Ho-Oh in my Gold and had traded over a Shiny Ditto from R/B/Y to try to breed for a Shiny, but then my internal battery died in both games. *sigh*
