You can head over to the page and "donate" tweets or Facebook likes to get Nintendo to share some badges and trailers about the upcoming Wii U game. (I have a hunch that they will release the trailer no matter what.) What you will not get for donating your hard-earned social media currency is anything resembling a fart. No little meter that farts its way up toward a goal-marker. Not buttons that fart when you click on them. No farts of any kind. For shame, Nintendo.
Update: Reader Thaelen points out that if you mouse over the pre-order or website buttons on the side of the page, Wario makes a farting sound. I wanted some juicy, real-sounding fart noises, but I SUPPOSE IT'S A START.
