Can you remember the last time you checked the Nintendo Channel on your Wii? Me either. As it turns out, you can get your hands on a free demo version of Kirby Mass Attack for your reliable DS or fancy, futuristic 3DS. The game, which features a massive hoard of Kirbys seeking a way to return to their original, single-puffball form, won't be out until September 16th.
