After successfully downloading the level 10 Rockruff, players will then need to go to a Pokémon centre and pick it up from the bearby Mail Man.

The Rockruff also comes with the item Focus Band, which have a 10 percent chance of protecting your Pokémon from fainting.

Players who pre-purchased Pokémon Gold and Silver on the 3DS's virtual console will also be able to grab themselves a Celebi Pokémon to use in game via a special serial code.
