White-Eyed Chomp - AI Experience Logs

This page was made to document the effects of the White-Eyed Chomp, an anomaly that signifies major personalization in a game. Anyone who has experienced the effects of this may add their 'log' to this page, for documentation reasons.

Brand New, never before played Super Mario 64 Cartridge was taken out and placed into console a total of 14 times until an instance of WEC appeared in Bob-Omb Battlefield. Game continued as normal until Big Bob-Omb bossfight was engaged. Big Bob-Omb was lacking his signature mustache, and his dialogue differed from the "Normal" game experience. Mario talked to BB, and BB claimed he was going to quote on quote "Play his ass like a trumpet." The fight continued, but BB moved at approximately 300% speed, and after almost 45 minutes of trial and error, once he was defeated, BB exclaimed nothing but "fuck", before exploding as usual and dropping his star.

So I inserted my cartridge and i saw the chomp. I broke his stump and let him go free. After getting the star, suddenly 119 more were granted almost instantly. A message appeared saying "Thanks" soon afterwards. Didn't see anything else happen.

Old cartridge, approximately from the early 2000's, the only save file in the game has been completed and resetted several times (approximately 6 or more). The WEC appeared, I was pretty a bit bugged off by its erieeness. Nothing much happened aside from that and no anomalies were witnessed in Bob-Omb Battlefield.

Minor personalisation like the absence of certain enemies and the usage of the dancing flower texture was witnessed, but nothing too big

Until I went to Jolly Roger's Bay, noticeably, there was a lot more surface you could walk on (this surface used the same texture as the main lounge of the castle), there were also Cheep Cheeps, no, not Bubs, I mean full-on Cheep Cheeps with no glasses, winged fins and small mouths.

Eel (now with white eyes, similar to the WEC) springed out of its cave much faster than in the "Normal" experience. After it slid completely out of its hole, I was surprised to find that there was an actually accessible area. This area was a seemingly bottomless pit, but thanks to the water, I managed to swim up, and actually get out of the pit, into a non-aquatic zone with textures similar to Dire Dire Dock's. This area was an incredibly long hall that ended with a single steel door, upon opening that door, I entered a chamber with the same textures, with a single Star in the centre. Once I grabbed the star, a single message appeared onscreen:

"b ware t one

avoid t fld."

Mario wasn't actually kicked out into the painting room of Jolly Roger's Bay, and instead, into the 2nd floor, right in front of the painting that leads to Wet Dry World, my coins were reseted to 1, my lives to 9 and my stars to 95. File deleted shortly afterwards, too.

Fandom Wikia user mailed his personalised cartridge of Mario 64, claiming it was of high interest due to the contents within. However, upon the cartridge being placed into the N64 Designated for Testing, a loud pop was heard and the pins of the cartridge were fried. After a few seconds, the cartridge caught on fire, melting the plastic, but leaving the insides mostly unharmed. Work is being done to rip the rom from this cartridge.

UPDATE: Rom was successfully ripped at about 8:40 PM today. Rom was loaded into an emulator, and gameplay began. Entire game was functionally normal except for an instance of WEC in BBF. Abnormally, even though WEC appeared, little to no changes/personalizations were actually made, especially large ones seen in past logs. Game advanced forward until the KBO boss battle, at which point the game crashed, and error screen was played simply showing. "Error: Unknown" The AI's ability to affect the game cartridge seems to extend to extremely abnormal things such as frying it's own cartridge

Experienced using childhood copy of the game. Let me preface this by saying that I've been on a big Phantom of the Opera kick in my time away from the game. So, upon going to Bob-Omb Battlefield to get myself reacquainted with the gameplay, I spotted the WEC and knew from what I'd something would happen. When I got the blue Star from Big Bob-Omb, I was ejected from the painting and all seemed normal until I got back out into the main foyer and looked up.

Somehow a large chandelier whose graphic is not known to exist in the game was now hanging in the spot between the sun rug and the sun ceiling, as if replacing the role of the latter. However, everything (including the Wing Cap stage, which I simply had to test) functioned normally, so I eventually got used to it.

And then, I went through the Dire Docks door. The Apparition appeared. I immediately shut the emulator off as recommended. Upon starting the game back up, I was able to resume the file. So, I went into the castle, which still contained the chandelier, and toward the main staircase. I didn't make it, because the chandelier suddenly fell, Mario right in its path! The screen went black, I saw my life at deplete in one go, and heard the voice of Wario laughing maniacally for a few seconds before I respawned. From here, the game preliminarily seems to have gone back to normal, though I have yet to properly investigate.

It wasn't until I put on the Phantom soundtrack later that day that I remembered that the personalizations are linked to the subconscious and realized why that had happened.

Recently started playing a copy that I had gotten a few years back. I started a new file and proceeded to play the game as normal, doing the stars in the intended order. I had left the stage to gather more stars from Whomp's Fortress so I could do the wing cap stage and come back to Bob-Omb Battlefield. I finished the wing cap stage with no issues and went back to Bob-omb Battlefield with 11 stars and completed the 100 coin star and Mario Wings to the Sky.

I went back in and did the sixth star of the level, "Behind Chain Chomp's Gate". While running up to where the normal chain chomp resides, I noticed the WEC immediately, and felt a slight bit of discomfort. I still did what you would usually do to obtain the star; pound the stump. However, the WEC did not react when the stump was in the ground and still behaved as a normal chain chomp would. I attempted a bomb clip but failed numerous times, and I gave up on the level.

There was some other anomalous behavior past this, such as the video on the CRT becoming grainy and distorted during moments of no significance (as it seems). The CRT works fine with other Nintendo 64 games, so I knew something was wrong with the game.

There was only a single boo in the Courtyard, and it drops a green key. I don't know if there is any way to access Big Boo's Haunt, and I am clueless as to what the key does. Minor alterations to the text are frequent. Some of the toads will address me directly, instead of Mario. Signs also have many blank sections in them after the original text is finished. (usually 3-10 blank boxes before closing) Jolly Roger Bay uses the Japan version's painting even though my cartridge is from North America. When trying to enter the aquarium level, I am sent back to the exterior of Peach's Castle.

My most recent and major anomaly I have discovered in my copy is the expansion of the castle grounds. I had defeated Bowser for the first time and afterwards a prompt stated that I had "unlocked more of the castle!" There was no alteration to the interior but instead the exterior. The moat extended back more past the back of the castle and there was walls bordering what seems to be the Courtyard. Next to those walls is a garden, using some weird dancing flower sprites I haven't seen before.

I am only halfway done with my playthrough, I will update this once I have finished my playthrough. - J

I saw this thing in my copy of Super Mario 64 I recently found in my dad's closet (I'm 14). After I ground-pounded his pole, instead of opening the cage and hopping off, he proceeded to bite Mario to death, as a constantly speeding up version of the Endless Stairs theme started playing. I tried to run away, but the Chomp soon mauled Mario to pieces. The grass then proceeded to turn red and Bowser's laugh was heard in the background. Then, The End screen appeared, only with the Mario figure on the cake being headless and covered in blood. Mario saying "Thank you so much for playing my game!" was replaced with a reversed version of the Endless Stairs theme. I replayed the game and showed it to my dad. He then proceeded to take the game and sell it on eBay. Nothing beyond that happened to this day.

I got a copy from my friend, who had gotten bored of the game after beating it so many times. I didn't have an N64, but i did have the ability to extract the ROM and run it on an emulator, which i did. I started a new file and decided to try the 16 star speedrun. When i was bomb clipping, i caught a glimpse of the WEC. I didn't know what it was back at the time though, so i continued. Everything went on mostly as normal, though i could swear mips was harder to catch.

When i got to the second floor and attempted the BLJ, i ended up somehow teleporting back down similar to the endless stairs. This happened about 3 times before i got enough speed and ended up launching through the wall, which then required me to spend a while slowing down.

Having accepted the fact that i'm not going to be posting the run on a leaderboard anyway, i continued through and into the endless stairs. I tried to perform the BLJ but the stairs wouldn't end even when i got to the point where i needed frame perfect inputs. Somehow, i actually pulled off a LOT of the frame perfect inputs in a row (i'm assuming this was part of the anomaly) but it still wouldn't take me to the final bowser level.

After a solid minute, the game just froze. I rebooted it and was greeted with a black screen, at which point i tabbed out. After a long time doing other stuff on my PC, i heard something. It sounded like a ticking coin counter. When i swapped back to the emulator, it just so conveniently booted up the title screen. After that, the game ran mostly normal, though everything seemed slow.

Having nothing better to do, i made it back to the WEC, which didn't gain their pupils back after the reset. After performing the bomb clip the game suddenly returned to normal speed, though it hanged on the dark transition screen for a weirdly long time. I got launched out of the painting as if I died despite my star counter going up and the star animation playing. I went back in just to make sure and indeed, the game believed i got the star.

I Decided to fight king bob-omb while i was at it. They ended up picking me up and tossing me off the mountain and back at the WEC. I escaped and went for a second round, where i got grabbed again and got thrown at the same position. I won the third time, though, which went as you would expect from an anomaly-less copy. Got the star, and i accidentally picked save and quit.

I decided that'd do for now, and left the game alone. Might return to it later, though.

After deleting my save files repeatedly in hopes of finding the Bowser Room and playing through Bob-omb Battlefield once again, I have encountered the White-Eyed Chain Chomp. It was my first encounter with this anomaly.

After letting the Chain Chomp go and getting the star, I returned to the castle once again. After running around the castle I noticed something. The Toad was missing, but the hitbox for the mushroom creature was still present. As soon as I pressed the A button, the game froze.

After restarting and pressing start, I noticed all of my save files were gone. All but one, the bottom right one. It had 19 stars, and so, I selected it.

I was in the endless stairs room, but there was no music. I tried to leave through the star door, but it wouldn't open. The only choice I had is to climb the steps.

I reached the end.

The hole to the final Bowser course was blocked, and the painting had no texture. I jumped into the painting, the name of the course was blank, as well as the name of the star. After selecting it, I was brought to an empty screen, slowly fading into an image of Mario with the wing cap, flying towards the sun. The music was just some simple chords, but it was weirdly nostalgic.

The N64 turned off by itself after a few seconds.

Hello, my name is Dick Kilby, and I am an AI researcher at the University of Maryland. I am researching how AI can be used to predict people’s behavior, and I heard new information about Super Mario 64. I have been able to obtain a copy and have been playing it recently, and I had a unique experience.

In the first world, Bomb-omb Battlefield, there is an enemy called a chain-chomp guarding a star. Typically, the Chain Chomp has white eyes with black pupils, is defending a star, and there is a sign next that tells players to watch out for it. This time, however, the Chain Chomp had pure white eyes, the star was gone, and the sign was instead telling players to “be afraid.”

I should note that the star was instead in the spot of the red coin star. I believe that the AI some-how relocated the star there and changed both the Chomp model and the text on the sign. How this happens, though, I do not know.

Downloaded a ROM from a website, game played as normal up until Bob-omb Battlefield. The cannon at the start of the course was already unlocked, despite no stars being obtained. Attempting to use the cannon seemed to crash the game. After reloading the ROM, I ran up to the chain chomp, and noticed its white eyes. I ran past it, but saw that a large gate blocked off the rest of the level. Most of the red coins were gone, aside from the one near the elevator platforms. Upon collecting this coin, a 1 appeared on screen, indicating that it was one of several secrets. It should be mentioned that no sound effect played when the coin was collected. Next, I tried to use the cannon in the field, hoping to get to the floating island. The cannon loaded as normal until right before switching to first-person view. At this point, the level restarted. I noticed that the coin counter still showed two coins as collected, indicating that the red coin would not reappear. Upon pausing, I found that the only option was to resume.

Next, I tried reading the sign next to the chomp, who's eyes were still white. It read "be afraid", just as Log No. 10 documented. However, the star was still there. I set the chomp free, and it immediately turned to face Mario for several seconds, then leaped over the hill, as if it had already destroyed the gate. The gate remained intact. I was a Mario 64 speedrunner many years ago, and decided to do bomb clip to attempt to get the star.

Though Mario was pushed through the gate, as soon as the bomb exploded, the screen flashed white, and the level restarted again.

Running out of ideas, I talked to the Bob-omb Buddy. His message read "please walk quietly in the hallway." I assume this is a tip of some sort for later on, as Bob-omb Battlefield does not contain a hallway. Shortly after this, the game crashed again.

I'll continue playing this ROM and keep everyone updated on what happens next. I need to either find a way to get a star here, or use glitches to attempt to access the basement with 0 stars.

During my playthrough of Bomb-Omb Battlefield, the White-Eyed chomp was encountered in my first run-through of the stage. As I usually do, I set the chomp free to get the first star of my file; Unsuprisingly, the chomp did as it usually does, and jumped back into the bars, before running off into the horizon. I collected my star, and returned to the castle. Yet, after the game saved and continued, a message appeared similarly to if I had first entered the castle, reading as follows:

"Mario! Mario! Something's at the door! It's black, and small, and... Gah! It's trying to bite me!"

Of course, I wasn't stupid. I got up, and grabbed my container of salt, as well as my hammer, just in case this was some kind of malevolent trick. But, when I got outside the castle, a small chain chomp greeted me. It was about as big as Mario's head, and simply jumped around. In a tree, though, a toad was clinging on for dear life. I long-jumped towards the toad, and - to my surprise - the chomp followed me. I tried to climb up the tree, but I couldn't; So, I pressed A in order to talk to the toad. This is what I got in response:

"You're here! Now get that thing away from me, It almost bit off my shoe!"

So, I tried to lead the chomp away from me; At first, I tried to enter the castle moat. I thought it worked, as the chomp didn't follow me in. But, it stayed on the outskirts of where I was, watching me in awe and periodically barking. There was no set pattern that I noticed; It just barked and followed me. So, I entered the castle, instead. The chomp once again followed me in, brushing past me as I entered the door. Finally, I returned to Bomb-Omb Battlefield, in a vain attempt to make it go away. It still followed me in, but instead of following me as it did in the castle, it ran over to the big chomp. The two chomps seemed to be happy, jumping with each other as I went over to them. When I got a few feet away from where they were playing - I think they were playing, I'm not really sure - the chomp seemingly nodded. The smaller chomp jumped on the pole as it did so, and the chomp released a star right above where the pole once stood. The two chomps then jumped away into the horizon. I collected the star, and, curious, I returned to the stage. I had two stars! But, one star was missing, still leaving me with six for Bomb-Omb Battlefield. I'm not too sure which one was missing, to be honest. But, whichever it was, I selected the star, and it read this message.

I started up my cartridge of Super Mario 64 and decided to make a new save file. I went to bomb-omb battlefield and immediately noticed the white-eyed chomp, except his eyes were bleeding and he was even more fast than normal. I groundpounded the stump and set him free then he began to devour all of the enemies in the level including the bomb-ombs. I ran up the mountain away from him while he was still distracted and met king bomb-omb except his mustache was covered in blood and he had no eyes. He had no text when i talked to him other than null. The fight began as normal until I defeated him then he exploded into a shower of blood and gore and it rained all over the arena while down with the sickness started playing on the mario 64 soundfont. Chain chomp got to the top and started to eat mario and my console caught on fire while down with the sickness played even louder and louder and more distorted. Eventually the game just crashed with warios face staring at me through the tv with hyper realistic eyes and my cartridge burned into ashes along with my nintendo 64.

So when I first got to the Bob-omb Battlefield the Chomp was completely normal, no white eyes or stuff like that. After I did the first mission and started the second star I saw that it had white eyes now. It spooked me so I exited the level, but saw that there was another door in the room with the painting. I entered the door and I was in some big textureless room, and there was a black box in the center. I interacted with it and the game crashed, but as soon as I restarted it there was this new cutscene playing where Bowser broke into the castle and snatched a couple of toads, then got outside and jumped away. After that Mario jumped out of the pipe and the game had basically resetted itself and I had nothing on me (I wasn't bummed out about it, I had only gotten a star).

I think that was a previous version of the cutscene where instead of Peach inviting you to her castle you would see Bowser breaking in and kidnapping some toads (maybe even Peach? Maybe they planned to make her hide in the glass stained thing for the whole game), but they scrapped it. After that the game continued on as normal, apart for the DLR thing and having the Fourth Floor.

So, my friend was screensharing himself playing mario 64, something seemed odd. The castle textures were reversed, the hud icons were like the beta ones. Upon entering bob-omb battlefield, it had the old textures for SM64. Going to the chain chomp, we both said something's wrong. We saw WEC. Upon freeing the chomp, everything was fine. He proceeded to collect to the star, after the animation ended he was thrown out in the old outside castle. The clock was a glitchy texture. He restarted the game.

He already had 120 stars, so he went to check the Dire, Dire Docks room. Everything was fine, he entered the paintng with star 1 selected. The sub was gone, there was weird swimming black boxes. The bowser door was invisible. He entered it and the normal warp worked. But a wario face flashed on the life counter. We both got scared but proceeded to play.

We then went into Bowser in the sky, everything was normal. The credits played perfectly fine until the Tiny-Huge Island part came. The level preview thing was flashing black, until we saw koopa the quick, where it stopped flashing. Then, mario probably just loaded in, causing a game crash (probably caused by memory filling up).

I do not remember more.

I'll try to just make this short because there is no need to get more into detail with other abnormal happenings I experienced because they're unrelated to this wiki page.

I was playing the second level of the Bom-omb Battlefield, Footrace with Koopa the Quick. I ripped a beta version of Super Mario 64 as a ROM earlier, and I didn't know what to expect because I am, admittedly, not too interested in Mario 64's earlier endeavors, but I decided to play this beta just to see if anything changed, and well, to no surprise, there was many things that were different.

However, when I approached the Chain Chomp, it's eyes were completely white. I figured the textures were like that during the beta stages, assuming the developers had better things to work on. In addition, the Chain Chomp was not intent on attacking me. In fact, it tried to run away from me before the chain restricted it -- it was like a scared animal, despite Chain Chomps being two times larger than Mario himself. So, I decided to stomp on the log which held the Chain Chomp. When I did, a sign appeared, and the Chain Chomp just dissipated out of thin air. Unfortunately, the bars that prevented Mario from getting the star were not broken, so if I intended on getting as many stars as possible in the game, that has been foiled.

I read the sign, and it said the following:

"Thank you for freeing me, but you are a"

I'm not sure why the sign didn't finished the sentence, but the ROM crashed about a minute later, and I was unable to restart it due to several errors regarding missing important files and not enough memory. I decided to search up my mishap on Google, and it appears that while some people did not experience crashes, they did encounter a Chain Chomp that just had pure white for its eyes. In addition, it would seem as this certain beta build of Super Mario 64 has some sort of sentient AI, and personalizes the game for you. I'm not sure if this AI has malevolent intent, but if this sentient program was the reasoning that I crashed, then I have to assume that it simply doesn't want me to play this beta build, possibly never again. Still, I am continuing to attempt to play this game without crashing it.

On my third playthrough of Bob-Omb Battlefield Star 4, using Project 64 2.3 as my Emulator of choice, I encountered an instance of the White Eyed Chomp. I had been recently reading about these things so I knew something would happen. Everything seemed normal, as I collected the star, but things started to change once I got back to the castle. My star count before returning was 13, but when I got back, it gave me 3 more than I got, bumping my total up to 16. I had already beaten Bowser 1 at this point, so I went downstairs checking for things. I encountered MIPS, who after chasing around led me to the Apparition. I ended the emulator, booted it back up to discover that the castle was now in the winter, the grass being replaces by snow. That seems to be all for now, but if something happens, I'll be sure to update this log.

Since I heard about the personalization A.I and the effects that can indicate it's existence, I decided I wanted to experience it for myself. After spending nights reading the wiki, I noticed one anomaly that could be easy to be found, and indicate what could happen next in my playtrough: The White-Eyed Chomp.

However, some of the users on the Discord server said I could not experience the A.I. on emulators, thus I had to move to a new idea, this one had to work. You see, my mother has a friend, and this friend has a husband. Her husband is an old-school player, and when I heard he owned a Super Mario 64 copy, my hopes were filled again, and last week, I was finally able to play an original copy!

The screenshot above was what I could get, while nothing "paranormal" happened, my experience surely was weird.

I plugged the game, and almost gave up when I realized the only control the dude owned was a pile of crap. Not only the stick was partially broken, meaning Mario could not run into specific directions, but is was also with a "greasy" substance. Anyways, I decided to continue playing even with a shit controller, and thus I got it. I quickly noticed the red skies, and then I saw it, the White-Eyed Chomp. I quickly made the mission to free it in order to get the start he was protecting, but after the Chomp has fallen off screen, I heard a "KAIN KAIN" sound, you know those sounds dogs make when in pain or when they are dying? Yeah, I heard those, along with some stars and dust particles where the Chomp has fallen.

I decided to check what was that, and got kinda shocket for what I've seen. The Chomp was lying on his side, his mouth was open, and his chain now dropped. He didn't move, and apparently now he was part of the scenery: A big corpse that you could climb on. I quickly got the star after that, nothing more of weird happened. When I returned, the sky was normal, just like the Chomp's eyes, wich came back to life along with everything I killed in the mission before. I sighed relieved and turned off the game.
