you import them
No, you can only migrate Pokemon from a GBA game to a DS game, not the other way around.
dimond and pearl
You have to migrate it from Pokemon FireRed, LeafGreen, or any other Pokemon game that you happen to have an Entei in. Entei can't be caught in Pokemon Diamond or Pearl. Sorry.
Chimchar is not obtainable in Pokemon FireRed or LeafGreen. The game it is in (Such as; Pokemon Pearl, Diamond, and Platinum.) is unable to connect to FireRed, unless migrating Pokemon from it, but Pokemon cannot be transferred into the Gameboy Advance games.
Mewthree is a Pokemon in only Pokemon Chaos Black,which is only a hacked game of FireRed and LeafGreen.But other than that it doesn't exist.
You can't. Misdreavius is in a fourth generation game (Diamond, Pearl or Platinum) and can't be traded back to a FireRed game.
no no You can migrate Pokemon from any GBA game to Diamond or Pearl, but not trade. you still get the Pokemon on diamond but you will not put new Pokemon in red
Pokemon fire is actually called Pokemon firered and it is a gameboy game which you can put in under you ds (the other game slot) and do a migration if you have a Pokemon game eg heart gold soul slver diamon pearl or platinum hope i helped
You can't find Turtwig on FireRed because he is in a different generation of the game. He is only found in Diamond and Pearl.
Rock Climb is not a move in the game. It wasn't a move until Diamond/Pearl/Platinum, which came out after FireRed.
No you can't. Since the DS and Gameboy Advanced is not backwards compatible, you can't send a Piplup (from a Diamond, Pearl or Platinum) game to Pokemon FireRed.
It depends on what game you have. If you have yellow blue red firered leafgreen, it is possible to get it in the game. In ruby sapphire or emerald you can trade it from leafgreen or firered. In diamond or pearl, you can migrate it.
