Things You'll Need
Instructions
Encounter all 150 Pokémon listed on the game's National Pokédex. These Pokémon are native to the Sinnoh region, and they include Carnivine, Toxicroak and Chatot. This is easier than it sounds, since all of the new Pokémon appear naturally during the course of the game's story.
Go to Sandgem Town and use a Pokémon's Surf technique to ride the waves south and east to the Pal Park. When you find land, continue down the path until you find the Pal Park at the end. Save the game.
Insert either "Pokemon Ruby," "Pokemon Sapphire," "Pokemon Emerald," "Pokemon FireRed" or "Pokemon LeafGreen" into the Game Boy Advance slot of your Nintendo DS and start your DS "Pokemon" game.
Select the "Migrate From" option on the main menu, and then select up to six Pokemon to import into the Pal Park.
Enter the Pal Park in your DS "Pokémon" game, and then talk to the man wearing the yellow hard hat to start a Catching Game. You are given six Park Balls and are let loose into the Pal Park to reclaim your Pokémon.
Walk through the different terrain types to find your imported Pokémon. Pokémon will stay in specific location types. For example, an imported Kangaskan will wait for you in the field locations, while an imported Dustox will be located in the forest. Throw a Park Ball at a Pokémon when you encounter it in the Park. The Catching Game ends when you recapture all of your imported monsters.
