On LeafGreen, I found a shiny Gastly and I evolved it to a Gengar, traded it to my friend to clone it a million times (3 times actually xD), but then he "lost it," and since he has a tendancy to sell his stuff, I couldn't check in what Emerald it was on (since there were like 3 people with Emerald in this neighborhood).
Also, I found a shiny Bellsprout on an island on LeafGreen, and I used HEAT WAVE on it!!! Fortunate IT MISSED!! =D But that's not the bad news, the bad news is that after I caught it, I transfered it to my OLD Diamond, and I lost it, along with my old DS. >.<
Also, my friend had a 10ANNIV Jirachi, and he said he wasn't going to trade me one because I wouldn't give him a shiny Gengar (WHICH HE "LOST!!") and later he sold that game to a little kid who deleted the file... -.- ...little kids these days... I don't blame them though.. they wouldn't look at an OT anyway..
