5:50 Stone Mario Hammer Suit was a form so godly powerful and forbidden it needed to be sealed away.

The Chain Chomp has always amused me. Like, why 50? Who is ever organically going to wait that long to discover it? Would have been an awesome normal enemy effect if it was say 3 or 5 lunges.

Finally one of these lists where it doesn't just show common things. Usually I know every single one... This one, I knew 5 only. Thanks.

The chain chomp escape was definitely in the player’s guide. I think Mario 64 also made a homage to it

In a Chuck 'e Cheese restaurant, climb into the stage when the curtain is closed, and enter the staff room. You will find Chuckie's suit hung up on a rack along with a computer on a small office desk.

Impressive list! I knew 10 of them, mostly stuff I've seen in speedruns or TASes, or while working on SMB3 videos. A few of things that blew my mind: - The Star kill boom boom I thought was gonna be obvious, but the star + block on the same frame got me! - The Fire Flower + Coin/Star block really blew my mind. Incredible interaction! - Bombs flashing using Mario's color made me really mad. How did I never notice this!!! These "x things you didn't know about this game" lists are always garbage, but I know a great speedrunner like you would actually deliver sick obscure knowledge!

One thing Mitch doesn’t know: it’s possible to wear a hat that’s a different color from his backdrop, so half his head doesn’t disappear when he keys out the background.

Most lists: Did you know that in Mario 3 there's goombas?! It's crazy! This list: Did you know that if you hit block 214 in level 3-4 with exactly 77 seconds on the clock you can turn Mario into a sentient pumpkin? But it softlocks the game :(

0:11 this is also a very good demonstration of how the cloud items in the sky are randomly generated :)

You can prevent a softlock with the Bowser star kill if you touch him for only one frame. If you kill him again anytime, it will softlock. Same with shells.

6:53 Killing diagonal Thwomps also allows you to juggle them, and they also keep their hitboxes after "dying", which is funny.

This is amazing. No fluff, just straight up content back to back. More please.

6:00 are you invincible forever too? if you can get out and touch an enemy

At 4:03 in the video, it shows World 5's map, but there seems to be a level that normally isn't there, leading to what looks like a "bypass" to go right to the Cloud part of World 5, skipping the tower (or "twisty castle) all together. I've never seen this before, and I've been playing Mario 3 since it came out. What's this secret, and why wasn't it on this list? Or is this because of a game hack?

5:30 that overworld music is a groove tho c:

That chain chomp one... is actually pretty common "hidden" knowledge.

1:10 Isn't that cute, he's trying to attack me lolz *OH SHI-*

damn that chain chomp thing is awesome i really wish it did it after 5-10 tugs instead so it woulda been implemented a lot more.

The tanooki statue to hammer suit glitch got me one time on accident. I went from super tough hammer suit Mario to dead little TIME UP Schmuckio.

5:53 the delivery on that line i love

Love this. I didn’t know many. I know you’re worried about the longevity of this game, but you are so entertaining, it’s not the game that makes you so. You could entertain in so many ways.

I really appreciate that your examples show imperfect clips and such. It's human and comforting.

That chain chomp one is so scary. Imagine just leaving the controller for fun, and coming back to seeing a chain chomp that has broken free all of a sudden, without your knowledge of why.

I knew about the 1up tune but it only happened one time and when it happened I had to ask myself "Did that really happen or am I hearing things?" Glad to see it really happen after all these 32 years on the 12th

OMG can't believe i've been watching for years and still didn't know things. The weird non-endings to some levels and the auto-death hammer bro were the main ones.

I knew about the chain-chomp one! It happened to me once when I was little (like 6?). I was messing around the level taunting the chain-chomp when it broke free and killed me. Scared the heck out of me! I never did figure out what caused it so I've always been very leary of any chain-chomps in SMB3 since because I assumed it was a random thing that could happen at any moment.

I knew about the 1up overflow sound glitch, the upside down orb, the chain chomp, the Warp Zone being World 9, making Mario clip through the pipe and disappear underwater, the hammer suit slide, the stone hammer suit softlock, and the Goomba Shoe glitch. The rest were all new to me.

Way back when SMB3 came out, the cartridge I had gotten was defective (I think). If I killed Bowser with the hammer bro suit, the game would freeze when I entered the door. None of my friends that had the game had this issue and I’ve never heard of anyone else have the same problem.

1:18 I actually knew this. Idk why….. I just do

0:37 should be used as a fnaf jumpscare

I knew about the door in 6-1, the odd 1-up sound, the glitched boot while holding a spiny, and the hammer suit having a slide animation of you get it while sliding, the warp zone being world 9, the 4th door, and the upside down orbs. I found all those playing this game as a kid, but a lot of the others are really obscure and were cool to see!

Mitch has forgotten more about this game than I will ever know. Love the game and mitch is the man. Cool video

Awesome Mitch! Enjoyed this one!

Never knew about that hidden music box, that is an INSANE secret.

The stuff I did know from this video was mostly learned from watching you, thanks for teaching us all the smb3 info Mitch!

I only knew Warp zone was world 9 😂 enjoyed this a lot!

😊 0:53 The Chain Chomp freeing itself on lunge 50 is terrifying 😊 Loving these information videos. Thank you so much for them

I knew about the glitched 1-up sound (thank you Retro Game Mechanics Explained), the chomp, the air walk off the sand, and World 9 (c'mon everyone knows that one). Cool stuff, looking forward to the rest.

I only knew two things here, Chain Chomp and stone hammer Mario. I can’t believe there were some secret places like 6-1 and 5-1 I never knew about!

The softlock for killing Bowser with a star was the only one completely alien to me. With the others, even if I didn't know that specific glitch or feature, I understood the mechanics. I read about the sliding Hammer Bro suit before, but didn't know how to trick the game into using it. Despite this, I'm also going to take a few steps back and say you got me with about half of them, even if I did understand how the glitch works.

1:04 Did you just discover that the chain chomps lunge SFX create a song when sped up?? It sounds very intentional, too.

I knew about the chain chomp, 1-up SFX glitch, stone hammer mario, world 9, the shell-holding glitch whilst in the boot and overkilling Boom Boom with hammers. I'd seen glitched pipe entries in TASes. Good list - most of these types of lists tend to be filled with well-known factoids so it's nice to learn some new things.

The 1up melody I found by chance and I always do it to the surprise of anybody watching me play. It's a great feeling seeing them go "Wow! What the hell was that? How did you do that!?"

I like that when the chain chomp hits Mario, he just stands there like "Bruh. What just happened?"

I only knew 3 of them. The chain chomp breaking free, the sky door in world 6, and the warp zone being world 9

I actually knew about the chain chomp one, and I'm sure a few others did too. They even left this in the Mario Maker games, but I haven't tested with any styles other than SMB3 yet

I'm sure I noticed a few of these 25+ years ago when I was playing SMB3 on a regular basis, and at least a couple more I've picked up from watching speed runs, but I'd forgotten nearly all of them before watching this video.

I played SMB 3 for the first time when I was only 3 years old. Many years later (crying in old), I knew about the Chain-Chomp breaking free, the 6-1 sky door, the pipe clip causing Mario to disappear in 3-9, and the Bob-omb flashing color being Mario/Luigi dependent, but that's about it. Nice job. :3

0:25 I see a poison mushroom. Why is there a poison mushroom in "Super Mario Bros. 3"?

Holy crap. I never knew about the Chain Chomp chain being breakable. That's awesome. Only one I knew was the Hammer Suit slide animation. That's about it. Also, how did I not notice the Bob Omb flashing colors? That's cool!

I actually heard the 1-up/tail swipe jingle once, but tought it was a glitch. Also, i knew about chainchomp and door 4. Stone hammer Mario and hammer on Boom Boom too

This game is by far the best game of my time playing this game with my daughter has been extremely fun she's 5 and I was not much older than she was when I played it for the first time . Retro games are awesome and I have a great appreciation to those who still play them and appreciate them

3:20 amazing

I only knew about the chain chomp. Didnt know it was 50 times though. I’ve just seen them come loose a few times. I knew about the 1-up sound from watching you. Cool video

That's crazy I play that game for over close to 40 years and never knew none of those it's amazing to see something never-seen-before on those

The chainchomp breaking free I accidentally found out as a little kid. Was playing the game and got distracted by something and idled by the chainchomp and when I looked back he broke free. Scared the crud out of me.

I knew a handful. But some were super interesting. Definitely would enjoy this as a series of videos.

Cool content. I knew most of ‘em.

2:43 - hol up theres a music box?

I'm just completely blown away. Super Mario Bros 3 is my favorite video game of all time. I've been playing since 1990. Every few years I learn something I didn't know about it. I'm seriously shocked. Several of these I didn't know. This game continues to amaze me after 33 years.

Wow. I did experience the chain chomp breaking off before, but I didn't realize it was a specific lunge count. I also knew about maybe 2 or 3 others of those, such as the door in the air at 6-1 and the fact that "world 9" existed. The one that has me most curious is actually the first one. If hammer bros in World 1 only drop items on a couple overworld spots, do the bros only ever stop on those spots? If you fight one of them on a different spot, is the chest empty at the end of the fight?

Can someone help me with this? I have a vague memory from when I was a kid of having a hammer in world one and smashing the rock at the second Toadhouse. Is that possible or am I having an odd memory of a strange dream I had once?

FANTASTIC content! Your voice is SO soothing too. I'd LOVE to see more videos like this 😃

Woohoo! I knew about 6:08!

I feel like the chain-chomp thing is incredibly common knowledge. I also knew about the invisible Mario glitch since that was a pretty old school glitch that you'd see mentioned in old Mario fansites. Though I guess there's a lot of information that's more obscure now since people now only go on like 4 or 5 sites for everything. For instance, you'd be surprised on how many people think the match-two minigame is randomized.

The Chain Chomp one blows my mind since it's clearly an intended mechanic. Sorta like waiting for 3 mins in Sonic CD

You are the ONLY person who has "Things You Didnt Know about X" vids that have some stuff I actually don't know. New sub earned!

I only knew the airship airwalk because you do it in all your runs. All the others were news to me.

1:29 - Me as a child: I knew it was possible!

i actually knew all of these

I knew about the Chain Chomp. The extended 1-up jingle, World 9, and the Hammer-slide. I'm impressed how much you had here that I'd never heard of! But you probably know this game better than anyone.

This is such a cool video. Something like this really has the potential to go viral mitch, if you have any more ideas like this it's worthwhile to produce them.

I knew that Chomps would break their chains eventually, but I thought it was based on time and not on how many lunges they did. I knew about the modified 1-up jingle from Retro Game Mechanics Explained. I knew about the 6-1 door because I think it was in the Nintendo Power guide...? I think I knew that the Warp Zone was World 9, or at least I probably noticed it at some point. I knew about the Rocky Wrench airwalk - _I learned it from watching you, okay Dad?!!_

I like this video. I like your line delivery, and how you just show everything. No fluff, no nonsense. I knew about the chainchomp, but not the rest of them.

I knew 4. The 1-up special tune happens to me fairly often. The 6-1 sky door was in an old players guide and so was the chain chomp limit. I've also gotten the pipe clip where Mario disappears on occasion. I thought the game soft locked me, but the screen was still scrolling so I imagined he was just invisible and made it to the end.

0:46 Boomerang bro killed itself

Been following u so long!! Good to see these kind of views in ur channel! 😍

I knew about 6-1 and the 9 worlds. Only reason I gave this a watch is because it was Mitch. Had it been anyone else I would’ve passed. I learned 23 new things for SMB3. Good job.

Nice vid. I follow classic game shit all the time and many of this I didn't actually know. Keep it up! Subbed!

When I first saw the title, I figured "Oh jeez, another clickbait... how much you wanna bet I know like all of these?", but then I noticed who the uploader was and became waaaaay more intrigued! Glad I did, since I only knew like 3 of these!

I knew about the chain chomp one and the World 9. Seeing the tricks with the Hammer Suit, especially the slide, made me smile.

Just watched this one AGAIN! GREAT video Mitch, thanx!!!

I was expecting to know most of them but only knew about the chain chomp and sliding hammer suit. Nice!

Making the Chain chomp fly out of the block only takes a minute

Knew about the chain chop breaking free, airwalking, sliding as Hammer Mario, Grey Hammer Mario, Warp Zone being World 9 and Bob-Ombs flashing color of Mario. Great video

I knew about 30 percent of them, some of the others such as 6-5 clip I did not know, also the bomb-ombs using your color, i never noticed that until you just mention it! But overall awesome video, thanks mitch!

I knew of a few, like the Warp Zone = World 9 one. Also, "Stone Hammer Mario" won't go in pipes because technically, you're still a statue, unable to turn back.

One trick I know about Mario 3 is using the whistle to go to repeat levels. It only works on worlds 5 and 6 (you have to start at 5 or 6, and you can only go to 5 or 6), but by repeating those two levels, you can get extra Tanooki and Hammer suits.

I was super impressed by this video and then I saw who made it and then was not surprised. Because Mitch is a GOD at SMB3

Before this video I only knew about the Chain Chomp, World 9 is the Warp Zone, and the 6-1 secret door. And I only knew about those because I bought the NES Game Atlas years ago, LOL.

A few other things people don't generally know about Mario 3 is 1. Bowsers hit box is only in his head and fireballs. Small Mario or ducking will avoid damage even when he stomps... So long as he doesn't hit you with a fireball. 2. Whenever you hit a block with a mushroom in it and it seems to go in a random direction. The direction the mushroom initially travels in can be controlled. It depends on which half of the block you hit. The mushroom will go the opposite direction of what side the block you hit. If you hit the block on the left half the mushroom goes right, if you hit it on the right half it goes left. Note: not all mushrooms follow this rule. Some will always go right. Stars can also be effected by this.

I knew a few of these, but only from the Super Mario Wiki page. Most I didn't know, they were interesting!

1:16 that's actually so obscure, you'd think they would make that happen sooner so it's more likely to be seen unintentionally

Actual stuff I didn't know about mario 3 and not clickbait. Good stuff Mitchflowerpower

Chain Chomp, Shoe and Boom Booms I knew before and all by my own... Offset Pipes and Shortcuts afterwards from KZfaq

I'm a sucker for these kinds of videos. Keep them up.

I knew a couple of these but most I did not. The chain chomp one and the sky door in 6-1 were the most surprising. I've played this game all throughout my life and never knew that happened

OMG i didn't know any of these,I thought at least I would know one of these

Chain Chomp one I knew cause I got the Mario 3 Guide as a kid, that book was so well made with the level lay outs and tips without going overboard. Miss that guide.

A handful of us knew all, and some.. mainly because we had too much time lol. Some of us have mentioned already spamming select at the title screen for the funny sound, the breaking of bricks in sky land castle where they break in thin air + the 1up, the fire snake with a star man as a head, and some mandella stuff. Mario 3 has not given up even a scratch of all its secrets and glitches. Keep at it folks, there will always be new vids of mario 3.
