Pok�mon Green
You may not know it, but there used to be a Pok�mon Green. It was the partner to Red. (This was in Japan in 1995). But for some reasons, Green didn't do well in the market, so they took it down and it was replaced by it's substitute, Blue. I don't know the details, 'cos I got this info on another webpage.
  I heard that the Pok�mon in green were ugly.

Pok�mon Red And Blue
The goal of red and blue is to catch and tame as many of the 150 Pok�mon as you can, but there's a snag. To get all 150 Pok�mon, you must trade for the other Pok�mon with someone who's got the other version using the Link Cable.
