Got a copy of Pokémon HeartGold or SoulSilver? You can download the Enigma Stone for your game from Saturday 31 July.
The Enigma Stone will allow you to go to the Pewter Museum of Science which is located in the north side of Pewter City in the Kanto region. It's exciting because it triggers the appearance of Eon Pokémon - Latias and Latios.
Once you've got the item you will receive the Soul Dew which is said to be the crystalised souls of the Legendary Pokémon Latias and Latios who made their debuts in Pokémon Ruby and Sapphire.
Latios will appear in Pokémon HeartGold while Latias will turn up if you have SoulSilver. When the Legendary Pokémon shows up it will attack you which is good as it gives you the chance to catch it.
This download is available from Saturday 31 July until 27 August. Will you download it via Wi-Fi Connection?
