In case you couldn’t tell, this is a shameless advertisement by Gamer Limit, for Toys R’ Us. Head out on the above dates to your local store and get your free Pokemon DLC. Or should I say Wi-fi content? Ho-ho!
I’d be kind of embarrassed to go, but hey, Gamefreak still makes good games! Basically, if you’ve never heard of this before, Toys R’ Us periodically sponsors events for DS enthusiasts, and if you visit on certain times, you can download a new Pokemon character to your game. The character is either completely new, and only available at special events (like Shaymin), or their unlock is so convoluted that you had better just go get them for free (Regigigas).
