eevee does only evolve into glaceon in dimond, pearl, platinum ss and hg
there in the same place as Pokemon dimond
I'm not sure if you can catch Eevee in Pokemon pearl but you get it as a gift from Bebe in Hearthrome City after you get the national dex.
you can't catch a ditto on Pokemon pearl or dimond but you can migrate from fire red or emerald
well platuim is the same thing as dimond and pearl i recamend to buy dimond or pearl because it has better story and kind a funner
