Oh dear lord, PLEASE let this be true! Rumor has it that Kellogg's is coming out with Super Mario Cereal. The cereal includes oat pieces with colored marshmallow Stars, Super Mushrooms, 1-Up Mushrooms, and ? Boxes. Even better, the box itself can serve as an amiibo! This sounds too good to be true, so let's hope it is!
So there's info that points to this both being fake and real. First off, it was posted over on the amiibo subReddit, which some people think points to it being fake. Second, a cereal blog says they've been doing research which points to it being real. I don't know which way to go with it right now!
UPDATE - Looks like we have even more evidence for this being real!
