becaus the only way to get one is through the trophy garden or trading and if you have 1 and no ditto u cant get anymore To otain an Eevee in Diamond: You can receive and Eevee from Bebe the Pokemon storage lady if you visit her house after receiving the national pokedex in Diamond. To receive the national pokedex you must view every Pokemon including the very last one (Palkia). Or you could get an Eevee in fire red or leaf green versions for the gameboy advance, which will work in the other slot in your ds. You find a pokeball which contains an Eevee in the team rocket's hideout in Celadon City, beneath the casino. Then while playing Diamond, have the leaf green or fire red in the other slot and go to the building where you can upload your Pokemon from a previous game and you have an Eevee! (You will have to catch it first) When you do get an Eevee in Diamond or pearl version you can mate it with Ditto to create even more!! This is good since there are 7 evolutions that Eevee can have!!
Pokemon diamond and pearl are exclusive to Nintendo ds or ds lite
Probably not, but you can find a lot of them at www.codejunkies.com under Nintendo ds/GBA/pokemon diamond
