ummmmmm.... this makes no sense!! :\
u get manaphy from pokemon ranger.. not from diamond or perl. u just have to recieve it through those games! but u said you already know how to get it. sand i cant make sense of ure post
if u mean to get him over from pokemon diamond when u already have him, then all you need to do is trade him to your perl game.. but again i dont understand what you mean sooo ~~cOnFUsEd~~
and whats the bit about the 5 pokemon???
