According to a new issue of Nintendo Power, Arceus will be given away at Toys ‘R’ US all over the US between November 7th and 15th. This event is compatible with Pokemon Diamond, Pearl, and Platinum for the Nintendo DS. This particular Arceus unlocks a special event that provides some backstory on the pokemon. When transfered to the upcoming HeartGold and SoulSilver titles, it will unlock yet another event that allows you to collect a Level 1 Dialga, Palkia, or Giratina.

This event is the last for the fourth generation of Pokemon, so fans are not going to want to miss it. All you have to do is take your DS or DSi to a participating Toys ‘R’ Us, select Mystery Gift from the title screen menu, and after Arceus downloads you are good-to-go.

We will post a reminder when the event goes live.
