It's a shiny pokemon. You should catch it, as shinies are very rare! :)
You need to get the event Celebi and then go to the shrine in Ilex Forest.
No you can only transfer a Pokemon to another game that has that Pokemon is that database. So You couldn't transfer say Entei to classic Yellow version because Yellow doesn't have it in it's database. But, for the new games I have not tried but just try and see what happens.
The cast of See What Happens - 2003 includes: Chris Hegedus as herself
Pon (yellow) and Zi (blue) ~ see related links below .
believe in your self and you will see what happens
Try it out and see what happens

Anywhere you see rocks going upwards (to check if you don't have it go to something if you think that's it, then hit A if nothing happens you can't climb it).
By using the TM Flash
You can trade one from another game, in soulsilver you can find a trainer with a chimchar, then go to the GTS and evolve it.
You can find them in tall grass and catch them, so yes, you do get to see them.
