this question is worded weird but if your question is "where do you get all thePokemon in Pokemon platinum?" then the answer is to battle every trainer in Sinnoh.
all of them in the regional pokedex
That pokemon is Azumarill in pokemon platinum in the national pokedex
Just go to Pokemon platinum central and click on pokedex and it shows you where to battle all the Pokemon in sinnoh.
