Kellogg's is apparently making Mario cereal. The cereal-focused website Cerealousy reported this week that it found references to a Super Mario Odyssey-themed cereal with star-shaped oats and marshmallow pieces in the shapes of coin boxes and 1-up mushrooms, among other things. Not only that, but the cereal box will apparently come with an Amiibo that unlocks something in Odyssey. We are excited about all of this.

A Cerealousy reader told the site that they received confirmation from Kellogg's that this Mario cereal is real and is coming to stores right now in the United States.
