You’re running through Big Boo’s Haunt, that creepy, creaking carousel music is looping in the background, and you stumble into a room that feels just a little too cramped. It’s the second floor of the mansion. There’s a bookshelf. There’s a sense of dread. And then, you see it: a massive, blinking eyeball. This is the Super Mario 64 eye to eye in the secret room encounter, a moment that has confused, terrified, and obsessed speedrunners and casual players alike since 1996.
It’s weird. Honestly, it’s one of the most unsettling parts of a game that is otherwise pretty bright and colorful. You’ve got this giant entity, officially known as Big Mr. I, just staring you down in a space where you barely have room to move. It’s the "Eye to Eye" mission, and if you don’t know the trick, you’re basically just fodder for a ghost-eye-laser-thing.

People always talk about the piano. You know the one—the Mad Piano that bites. But for my money, Big Mr. I in that cramped secret room is way more iconic. It represents that specific era of Nintendo design where they weren't afraid to make things a little "off." It’s a puzzle, a boss fight, and a lesson in 3D movement all wrapped into one bizarre interaction.
What is Big Mr. I and Why Is He Staring?
To understand the Super Mario 64 eye to eye in the secret room challenge, you have to understand Mr. I. These enemies are basically just giant floating eyeballs. Most of them are small. You find them in the Lethal Lava Land or the lower levels of the mansion. They track Mario’s movement with a cold, unblinking precision.
But Big Mr. I? He’s the boss version. He only shows up in this specific secret room behind the bookshelf in Big Boo’s Haunt. To even get to him, you have to navigate the second floor, find the room with the shifting books, and punch them in the right order. 1-2-3. Or is it 3-2-1? If you mess up, a small book shoots out and hits you. If you get it right, the shelf slides away like a scene from a classic horror flick, revealing the lair of the giant eye.
Once you’re in there, the camera gets wonky. That’s the real difficulty. The room is tiny. Big Mr. I takes up a huge chunk of the floor space. The game’s logic dictates that to kill a Mr. I, you have to run circles around it until it gets dizzy and pops. But in this secret room, the walls are your worst enemy. You’re trying to maintain a tight radius while the Lakitu camera struggles to keep both you and the eye in the frame. It’s claustrophobic. It’s frantic. It’s classic Mario 64.
The Secret to Beating the Eye
Most people panic. They try to long-jump or dive. Don’t do that. You’ll just hit the wall and lose your momentum. To win the Super Mario 64 eye to eye in the secret room showdown, you need to exploit the game’s physics.
Mario’s turning circle is actually quite tight if you’re not at full sprint. The trick is to stay as close to the eye as possible. If you stay close, the distance you have to travel to complete a 360-degree rotation is much shorter. Think about it like a record player. The closer you are to the center (the spindle), the less distance you cover per rotation.

Once you start spinning, don't stop. If you break the chain, Big Mr. I resets his "dizziness" meter. You have to circle him about two or three times quickly. When he finally gives up the ghost—literally—he spins out, shrinks, and vanishes, leaving behind a Power Star. It’s a satisfying "pop" sound that every N64 kid remembers.
Why This Room Still Creeps Us Out
There’s a lot of "L is Real" and "Every Copy of Mario 64 is Personalized" creepypasta out there. Most of it is total nonsense, obviously. But the reason those stories work is because of rooms like this. The Super Mario 64 eye to eye in the secret room encounter feels like it belongs in a different game.
The lighting is dim. The silence of the secret room, contrasted with the muffled carnival music outside, creates this weird sensory deprivation. It’s a masterclass in atmosphere. Nintendo EAD, led by Shigeru Miyamoto and Takashi Tezuka, were geniuses at using technical limitations to create mood. They couldn't render a high-def horror scene, so they used a giant, staring eye in a closet. It worked.
Interestingly, some players have reported a "glitch" where the eye doesn't follow you correctly if you enter the room while holding certain items or using the Vanish Cap. While the Vanish Cap makes you invisible to most enemies, Mr. I can often still "see" you because his logic is tied to Mario's coordinates, not just a line-of-sight check. It's these little technical quirks that keep the speedrunning community digging into the code decades later.
Technical Breakdown: The Dizziness Mechanic
If we look at the actual code—thanks to the massive decompilation projects like n64decomp—we can see how this works. The game tracks the angle between Mario and the center of the Mr. I object. When that angle completes a full 360-degree sweep in a short window of time, a counter increments.
- Rotation Check: The game doesn't care about your animation; it cares about your position relative to the enemy's center point.
- Speed Matters: If you move too slowly, the "dizziness" value decays. You have to be consistent.
- Collision Boxes: The secret room has "invisible" walls that are slightly offset from the visual textures. This is why you sometimes feel like you're bumping into nothing while trying to circle the eye.
Common Mistakes in the Secret Room
I’ve seen people try to punch the eye. It doesn’t work. You can’t ground pound it either. The only way is the spin. Another mistake is trying to use the C-buttons to fix the camera mid-spin. In that tiny room, the camera is scripted to stay in a semi-fixed position. Poking at the camera controls usually just leads to Mario running straight into a wall, breaking his circle, and getting shot by the eye’s projectile.
Just focus on the joystick. Ignore the camera. Trust your muscle memory of where Mario is in the space.
Impact on the Speedrunning Community
In a 120-star run, the Super Mario 64 eye to eye in the secret room star is a potential run-killer. Why? Because if you get knocked back by the eye, you might fly through the "door" (the bookshelf) and end up back in the main hallway. Loading screens in 1996 were fast, but they weren't instant. Plus, you have to redo the book puzzle.
Top-tier runners use a specific movement pattern. They enter the room, immediately dive-recover to get close to the eye, and then perform a very tight "C-up" circle. It’s over in about three seconds. For the rest of us, it usually takes about thirty seconds of sweaty-palmed circling and praying we don't hit the corner of the shelf.
Exploring the "Personalized" Myth
Back in 2020, the "Internal Pleasing Service" and other Mario 64 conspiracies took over the internet. While mostly fictional, the Super Mario 64 eye to eye in the secret room was often cited as a "trigger" for weird game behavior. People claimed that if you stared back at the eye for too long without moving, the game would crash or show a distorted image of Mario.
None of that is true. I’ve tested it. I’ve looked at the source code. The eye is just an object with a script. But the fact that people believed it speaks to how effective the design is. It feels like it should be haunted.
How to Get There: A Step-by-Step Refresher
If you're jumping back into the 3D All-Stars version on Switch or dusting off your old N64, here is exactly how to find this star.
First, enter Big Boo’s Haunt. You need at least 12 stars to even unlock the mansion (the Big Boo in the courtyard). Once inside, head to the second floor. Look for the door on the far right. Inside is a room filled with books.

- The Puzzle: Walk toward the bookshelves at the back. Books will fly at you. You need to hit the three books that are sticking out. The order is: Center, Right, Left. (Wait, let me double-check that... actually, it's usually Top, Bottom, Middle in terms of position, but the standard sequence is middle, right, left).
- The Reveal: Once the shelf slides, walk through the gap. You are now in the secret room.
- The Fight: Walk toward the center. Big Mr. I will appear.
- The Victory: Circle him quickly. Stay tight. Don't hit the walls.
Actionable Tips for Modern Players
If you’re struggling with the Super Mario 64 eye to eye in the secret room mission today, especially on the Switch Pro Controller, keep these things in mind. The sensitivity of the modern joystick is much higher than the original N64 "chunk" stick.
- Throttle the Stick: Don't push the joystick all the way to the edge. Push it about halfway to maintain a slower, more controlled run. This prevents the "wide turn" that usually ends in Mario hitting a wall.
- Shadow Watching: Look at Mario’s shadow on the floor. It helps you judge your distance from the eye better than looking at Mario’s body, especially when the camera angle gets steep.
- Ignore the Projectiles: Big Mr. I shoots small blue bubbles. If you’re moving in a circle, they will almost always miss you. Don't try to dodge them individually; just keep your circle going.
The Super Mario 64 eye to eye in the secret room star remains one of the most memorable "hidden" moments in gaming history. It’s a perfect example of how Nintendo used simple geometry and clever environment design to create a boss fight that feels much grander—and creepier—than it actually is. Next time you're in the mansion, give the big guy a wink for me. Or just run around him until he explodes. Either works.
To master this room, practice your "tight circles" in a safer area like the castle courtyard first. Once you can spin Mario in a diameter roughly the size of a coin without breaking stride, the Big Mr. I fight becomes trivial. Remember that consistency in your circular motion is more important than raw speed. If you can maintain a steady rhythm, the game's rotation counter will trigger much more reliably than if you're jerkily moving the stick.
