Super Mario Cereal Amiibo

Super Mario Cereal (released 2017) is a Kellogg's breakfast cereal featuring a built-in NFC chip in the box that functions as a functional Amiibo.

There's still plenty on ebay with the cereal still intact, make sure you don't eat it. Get it if you are a collecting all amiibos, Mario amiibos or you want to complete your Odyssey collection.

Otherwise it's just a cereal box
