If it is a happiny then I already know whats going to happen to brocks love life.The Happiny will evolve to Chansy and nurse Joy will think thats attractive and well you know where Im going with this

I think it's a happiny just to go with the diamond/pearl idea (you get a happiny egg there)

Pink egg with a white ring going around it = Happini.
Coz a fellow league player of mine has seen the Darkrai Movie (she went to Japan) & she said the he's got a baby Chansey.
Then see looked & my Pearl & said that he had that one (Happini).

She couldnt have seen the movie yet cause its not even out. I know so cause I live in Japan. Its doesnt come out till July 14. But I know for A fact that it is Happiny. There is A little poster in Japan that showa all of the characters and geuss what?! Brock is holding A Happiny. So its so obvious that it will be Happiny.
