You may not get to experience this one for a while, especially if your birthday is in early November. But the Wii U knows, and it'll wish you a happy birthday with a short round of applause from the Miis in your plaza and a modest burst of confetti. It's not much, but what are you expecting, a personal letter from Miyamoto himself? Take what you can get!
Here it is on Youtube.
Did we miss any important functions of the Wii U? Do you know something we don't?
