the way you do it is you no that poke fan club house in slateport
i think anyway im glad to help!!!!!!!!!!!!!!!!
In Pokemon Ruby,Sapphire and Emerald after you make a pokeblock, you can check the pokeblock case and you give the desired Pokemon the pokeblock to help it do better in Pokemon contests. After you have received a pokeblock case and you made pokeblock at the berry blending machine go to your key items in your bag and scroll down to your pokeblock case then simply select the pokeblock you want to give your Pokemon.
This depends on the pokemon's nature, not the species.
you need to get the pokeblock case
Pokeblock's are not in diamond instead there called poffin's, just like ruby, sapphire and emerald in the Pokemon contests you can create your own poffin using berries.
you have to thorw a pokeblock, the more the better, but be careful,,,they might run away
in what Pokemon? in Pokemon ruby/sapphire and maybe emerald too, a girl in slateport contest house give it to you
a place filled with Wynaut 5-50 and a rare berry that makes a gold pokeblock
In Slateport City, there's a hyper rank contest place. Inside, talk to the little girl and she'll give it to you.
Mix one out of berries. It will be in your pokeblock case. Feed it to the Pokemon that you want to give the pokeblock to.
Go to the contest hall in Slateport City. Once you get there, ask the little girl in the left side of the room, she will give you a pokeblock case. :)
Now you can't normally do this unless you go in the safari zone in ruby, sapphire and emerald and put a pokeblock in the pokeblock feeder. See here's the cool thing about the pokeblock feeder, the Pokemon that normally appear in that area will either go for the food or not go near it so chances of finding certain Pokemon actually increase so lets say you want to find wobuffet put a pokeblock that is either indigo or green chances of finding it now has increased!
The point of a pokeblock is by mixing berries in berry blenders together after mixing the berries you give a taste if the pokeblock is the right flavor for your pokemon and also It helps in pokemon contest and battles by raising your pokemons contest skill And the recomended pokeblock that you will have to make is the red pokeblock
