Toys R Us has announced the details for the Jirachi distribution in Australia. Toys R Us will be allowing players of Pokémon Diamond, Pearl, Platinum, HeartGold and SoulSilver to download Jirachi via Mystery Gift from June 3rd, 2010 to June 13th, 2010. Toys R Us are also selling Pokémon Plushies for $2 each as part of the promotion. Plush characters vary by store and are strictly limited.

Players can use the Jirachi they receive in Pokémon HeartGold or SoulSilver to unlock a new special route inside the Pokéwalker called Night Sky's Edge. This is the only way this route can be accessed! Players may only receive one Jirachi per game cart.

Jirachi is a Level 5 Pokémon and it holds a Liechi Berry. Jirachi also knows Wish, Confusion, Rest and Draco Meteor.
