Hop into McDonald's to get Hoopa for a limited time!
All you have to do is head to McDonald's with a copy of Pokemon X/Y/OR/AS and connect your 3DS to the Nintendo Zone after logging into the free Wi-Fi.
It's nice that this promotion is available for all four of the main Pokémon games for 3DS, but when it's in OR/AS it can transform into Hoopa Unbound! There is no information yet as to if this is a US based event only. This is one of the longer Pokémon events in recent years but don't delay to get this sucker.
