hes not in platinum:( try ruby
do like Pokemon
a master ball. you only get one. someone gives it to you (i think the galactic boss guy, but that might have just been in platinum)
I'ts a guy who look at pokemons footsteps and sometimes gives them a ribbon called "Footstep ribbon". He only gives it to big Pokemon like Dialga and Palkia. Good luck:-)
The digger guy who gives you and exploration kit is in Eterna City next to the Pokemon Center.
no man gives you a happiny platinum only in diamond and Pearl
you get a poragon in a town a guy in a house gives you one
the guy from the team galactic gives you one to catch girantina in the distortion world
from the pokech guy
on th bike path heading south before you go out of the little border or watever there is a guy that gives it to you if you've seen 30+ Pokemon
theres a guy who gives you 5 of them if you show him a certain pokemon. hes thenews reporter guy in solaceon town. they dont start selling them until after the 7th or 8th badge.
It depends.
