You know the sound. That rising, shimmering "ba-ding" when Mario touches a Super Mushroom. It’s iconic. It’s practically the heartbeat of Nintendo. But if you stop and think about it for even a second, the whole concept is incredibly bizarre. Why is a plumber eating a mushroom to double in size? Honestly, the story behind super mario bros mushrooms is less about logic and more about a desperate need to solve technical problems in the 1980s.
Shigeru Miyamoto and his team at Nintendo EAD weren't trying to make a statement about mycology. They were trying to figure out how to make a player feel powerful without breaking the game's difficulty. The mushroom wasn't even in the original plan. It showed up because they realized Mario looked way too small on the screen compared to the vast world they were building.

The birth of the Super Mushroom and the "Big Mario" problem
Early on in the development of the 1985 classic, Mario was just a tiny guy. One hit and you were dead. It felt unforgiving. The team realized that if they gave Mario a second "life" within the level, it would make the game more accessible. They needed a visual cue to show that he was now in a powered-up state.
They tried a few things. Eventually, they settled on the mushroom, partially inspired by folklore and tales like Alice in Wonderland, though Miyamoto has later clarified in interviews that the Alice connection was more of a subconscious vibe than a direct "let's copy this" moment.
Basically, the super mario bros mushrooms act as a buffer. In the original NES code, "Small Mario" and "Super Mario" are actually treated as two different characters that the game swaps between instantly. When you hit that red-and-white cap, the game engine pauses for a split second, swaps the sprite, and suddenly you're twice the size and can break bricks. It’s a simple trick that defined a genre.
The dark side of the 1-Up Mushroom
Then there’s the green one. The 1-Up. In the early days, these were rare. They were tucked away in invisible blocks that you only found by accident or by reading a strategy guide in Nintendo Power.
There’s an old piece of trivia that people love to repeat: the idea that the 1-Up mushrooms grow on the graves of fallen Marios. It’s creepy. It’s also not officially canon, but it speaks to how much these items have seeped into our collective imagination. In reality, the green color was just an easy palette swap for the NES hardware. Green meant "go" or "extra," while red meant "power."
Evolution beyond the red and green
By the time Super Mario Bros. 3 rolled around, the mushroom family tree started getting weird. We got the Super Leaf (which technically isn't a mushroom, but fills the slot) and eventually, in later games, things like the Mini Mushroom and the Mega Mushroom.
The Mega Mushroom from New Super Mario Bros. on the DS is a personal favorite. It’s pure chaos. You grow to fill half the screen and just wreck everything—pipes, flagpoles, enemies. It turned the super mario bros mushrooms from a survival tool into a weapon of mass destruction.
Does the Toad factor make it weird?
We have to talk about Toad. He’s a mushroom person. Mario eats mushrooms. Does Mario eat Toad’s relatives?
Nintendo has been dodging this one for decades. In the Super Mario Bros. Movie (2023), they lean into the mushroom kingdom as a literal ecosystem where some fungi are sentient and others are just "power-ups." But if you look back at the original manual for the 1985 game, the lore states that the Koopas turned the citizens of the Mushroom Kingdom into stones, bricks, and... field horsehair mushrooms.
Yeah. Every time you eat a mushroom or break a brick, you might be interacting with a transformed citizen. It’s dark. It’s probably something Nintendo wants us to forget.
The science (sorta) of the Amanita Muscaria
The visual design of the super mario bros mushrooms is clearly based on the Amanita muscaria, also known as the Fly Agaric. You’ve seen them in pictures: bright red with white spots.
In the real world, do not eat these. Seriously. They are toxic. They contain muscimol and ibotenic acid, which are psychoactive. While some cultures have used them in shamanic rituals, they mostly just cause nausea, twitching, and—interestingly—distortions in how you perceive the size of objects. This is called macropsia or micropsia.
It’s a wild coincidence (or maybe not) that a real-life mushroom known for making things look bigger or smaller became the universal symbol for a video game character growing in size.
Why the mushroom still matters in 2026
Even now, with all the crazy power-ups like Elephant Fruit or Wonder Flowers, the basic mushroom remains the most recognized icon in gaming. It’s a universal symbol for "improvement."
You see it on t-shirts, in LEGO sets, and as icons on our phones. It’s survived because it’s a perfect piece of design. It’s high-contrast, easy to recognize even in low resolution, and it feels rewarding to grab.
How to use mushrooms effectively in modern Mario games
If you're playing Super Mario Wonder or Mario Maker 2, don't just treat mushrooms as a health bar. They are momentum tools.
- Damage Boosting: Sometimes it’s worth taking a hit from a Goomba while Super Mario just so you can use the post-hit invincibility frames to run through a harder obstacle.
- Storage: In games with an item reservoir, keep a mushroom as your backup. It’s tempting to hold onto a Fire Flower, but a mushroom is often better for tight platforming sections where being "Big Mario" is actually a disadvantage due to your larger hitbox.
- Crouch-Jumping: Remember that as Super Mario, you can slide and crouch-jump into gaps that Small Mario can just walk into. It opens up secret paths that a casual player might miss.
Actionable steps for the modern player
If you're looking to dive deeper into the mechanics of the Mushroom Kingdom, start by experimenting with the physics of growth. Go back to the original Super Mario Bros. on Nintendo Switch Online. Try to beat World 1-1 without ever picking up a mushroom. It’s harder than it looks because you lose the ability to break blocks that might lead to safety.
Next, check out the "Super Mario Encyclopedia" or the official Nintendo "Iwata Asks" interviews. These archives contain the actual design documents where the team debated the "bigness" of Mario.
Finally, if you're a creator in Mario Maker, use mushrooms as a "gate." You can design levels where a player must be Super Mario to break a specific ceiling to progress. This is the foundation of "Metroidvania" style design within a platformer.
The mushroom isn't just a snack. It’s the DNA of level design. Every time you see that red cap, you're looking at the solution to a 40-year-old programming hurdle that changed how we play games forever.
