I blame NintendoPie for this. It is a known face people like Pie, and numbers like Nintendo. So by putting the character next to Nintendo and Pie, it has caught on, and gone viral, via associations of likes.
Now, if NintendoPie were called say, "NintendoCake" it might not of caught on, because we know that the Cake is a lie. So the lie and Nintendo offset one another. But put the character next to Nintendo AND pie, and you end up with an explanation of a viral outbreak.
I am wondering whent the YouTube parody of this viral outbreak linked to Resident Evil will happen. The outbreak turns people into Pip characters, rather than zombies.
