Mario amiibo cereal is the fan nickname for Kellogg's Super Mario Cereal, a limited-edition breakfast product that also worked as a real Nintendo amiibo. Released in 2018, it combined berry-flavored cereal and Mario-themed marshmallows with an NFC chip embedded directly in the box. That chip let players scan the packaging on a Nintendo Switch just like a plastic amiibo figure.
For collectors and Nintendo fans, the Mario amiibo cereal represents a strange but fascinating intersection of food, toy, and video game. It was not just a promotional gimmick. The box actually unlocked in-game content, which turned a simple breakfast item into a sought-after piece of gaming memorabilia.
What Exactly Is Mario Amiibo Cereal?
The product's official name is Kellogg's Super Mario Cereal. It appeared on U.S. grocery shelves in December 2018. The cereal itself was a berry-flavored mix with marshmallows shaped like Mario's head, Super Mushrooms, and Super Stars. The packaging featured Mario, bright colors, and a clear amiibo logo.
What set it apart from every other cereal was the side panel. Inside that panel was an NFC tag, the same technology used in standard amiibo figures. By holding the box against a Nintendo Switch's Joy-Con or Pro Controller, players could trigger in-game reactions. This made the Mario amiibo cereal a functional gaming accessory, not just a clever box.
The Kellogg's and Nintendo Collaboration
Nintendo and Kellogg's partnered to create a cereal that would appeal to both kids and adult fans. The collaboration was announced in late 2018, and the product was positioned as a limited-edition item. Marketing leaned heavily on the amiibo feature, which was unusual for a food product.
The cereal was sold in major retailers like Walmart, Target, and Kroger. It was never intended to be a permanent addition to the cereal aisle. Instead, it was a time-limited promotion tied to the popularity of Super Mario Odyssey and the wider amiibo ecosystem. That limited run is a major reason why sealed boxes are now collectibles.
How the Box Works as an Amiibo
The amiibo functionality is built into the box itself. A small NFC chip is embedded in the cardboard, usually near the amiibo logo on the side panel. When you scan it, the Switch reads it exactly like a standard amiibo. You do not need to open the box or remove the cereal.
Because the chip is inside the packaging, the box must remain intact for the amiibo to work. If the box is crushed, wet, or cut through the wrong area, the NFC tag can be damaged. That is why collectors often keep the cereal box sealed or store it carefully in a protective case. The cereal inside is long expired, but the digital reward still works if the chip is intact.
In-Game Rewards and Compatibility
The main reason people sought out Mario amiibo cereal was its in-game reward. In Super Mario Odyssey, scanning the box unlocked a special costume called the Mario Cereal outfit. This outfit is a white shirt with a red collar and a bowl of cereal graphic, making it a wearable piece of breakfast-themed gear.
The box also gives coins when scanned. The first scan typically unlocks the outfit, while later scans provide a small coin bonus. This made the cereal box a convenient way to grab extra coins without hunting for them in the game. For completionists, the outfit was a must-have because it could not be obtained any other way.
The Mario Cereal Outfit in Super Mario Odyssey
The Mario Cereal outfit is one of the quirkiest costumes in Super Mario Odyssey. It consists of a white shirt with a red collar and a picture of a cereal bowl. The design references the actual Kellogg's box, complete with Mario's face on the cereal pieces. It is a fun, self-aware reward that fits the game's playful tone.
To get it, you need to scan the cereal box while playing Super Mario Odyssey. You can do this from the costume menu or by using the amiibo option in the game. Once unlocked, the outfit stays in your wardrobe. Even if you later sell or lose the box, the outfit remains available in your save file.
Using the Cereal Box with Other Nintendo Games
The Mario amiibo cereal is recognized as a generic amiibo in many other Nintendo Switch games. In The Legend of Zelda: Breath of the Wild, for example, scanning any amiibo gives you a random item drop once per day. The cereal box can trigger that same effect, though it will not unlock Zelda-specific gear.
In games like Mario Kart 8 Deluxe, amiibo can unlock character-themed racing suits. The cereal box may register as a generic amiibo, so results can vary. In Splatoon 2, it can be used to save loadouts, but it will not grant the special gear tied to dedicated Splatoon amiibo. Compatibility depends on the game, so it is best to treat the cereal box as a fun bonus rather than a universal key.
Collecting, Taste, and Legacy
Today, Mario amiibo cereal is no longer produced. It was a limited-edition item, and once stores sold out, it was gone. That scarcity has turned it into a collector's piece. Sealed boxes are especially desirable because they preserve both the packaging and the working NFC chip.
The cereal itself was a sugary berry-flavored product with marshmallows. It tasted similar to other berry-flavored Kellogg's cereals, with a sweet, crunchy texture and a light fruit flavor. Nutritionally, it was a treat, not a health food. But for collectors, the taste is secondary to the novelty and the amiibo feature.
Availability and Collector Value
You will not find Mario amiibo cereal in grocery stores anymore. Your best bet is online marketplaces like eBay, Mercari, or Amazon third-party sellers. Prices vary widely based on condition. An opened box with a working chip might sell for $15 to $30, while a sealed box can fetch $40 to $80 or more.
Some sellers list just the box without the cereal to reduce shipping costs. Others sell the cereal itself as a novelty item, though it is expired and not safe to eat. If you are buying for the amiibo function, ask the seller to confirm the NFC chip still works. A quick video of the scan can save you from buying a dud.
Flavor, Nutrition, and Cultural Impact
The cereal base was berry-flavored, and the marshmallows were shaped like Mario's head, mushrooms, and stars. It was sweet, crunchy, and designed to turn the milk a slight berry color. Kids loved it, and adults bought it for the collectible box. The nutrition label was typical for a sugary cereal, with high sugar and low fiber.
Culturally, the Mario amiibo cereal is a milestone in interactive food marketing. It showed that packaging could be more than a container; it could be a game accessory. The idea has not been widely repeated, which makes this cereal a unique artifact of the Nintendo Switch era. For fans, it is a reminder of a time when breakfast and gaming collided in the best possible way.
If you are a collector, keep an eye out for sealed boxes at reasonable prices. Check the amiibo chip before buying, and store the box away from moisture and heat. Whether you display it on a shelf or use it to unlock that odd cereal outfit in Super Mario Odyssey, the Mario amiibo cereal remains a deliciously weird piece of Nintendo history.
