I've got a shiny mankey :mankey:, I mentioned that in my first post. I found it in leafgreen on my way to Victory Road just before the Elite Four.
Anyway, I still haven't gotten any shinies in trades, but I'm looking for Gyarados, Cubone, Kangaskhan, Gengar and Milotic as well as any legendaries. Cubone is top priority,
Also, I read today in a faq (no telling how reliable it is though) that in Silver/Gold/Crystal shiny pokemon were pokemon who had acceptionally high IV's (Individual Values=a pokemon's extra points that are completely random with every pokemon.) Shinies aren't any tougher than regular Pokemon anymore, which is lame.
