Super Mario Bros. but the floor is Radioactive Waste 

Mini-Mario's head saying bye-bye and jumping off was way funnier than it should have been.

The creativity and animation in this video is over 9000. Absolutely amazing! What worries me the most now is, the amount of radioactive mario videos that are gonna pop up in about a week from all those copy-paste rip off mario animation channels

Seriously, Nintendo should hire you for level design. Your videos are really original, and I would love to play this in an actual game

All of these music remixes and level ideas are amazing. They can easily turn into normal mario levels!

0:28 Mario has a damage meter

2:52 ain't no way they made Mario Mario into The Wither from Minecraft bruhh 💀💀

That radiation bar is a really interesting mechanic, a lot better than the instant-killing poison floor Mario games usually have. Also, Mario growing extra parts was pretty funny as well. Hope he finds enough coins to get rid of those two new heads. In his case, I feel that him having three heads would result in him making three times more mistakes than usual.

1:05 knew it was coming!! 😅

I think I'm starting to sound like a broken record player, but every time I'm astounded by your creativity in these videos.

2:36 How did that not vaporize him?

This needs a sequel! Who else agrees?

1:47 that shape looks sus

1:59 mario has a buddy on his head

2:25 Buh Bye

2:13 RADIOACTIVE KING BILL

Mario's in chernobyl

*0:08* - Radioactive waste is _terrifying._ 😨

2:52 Three heads Mario! XDXDXD

1:19 these pipes looked like they were 3D

Alternative title: Super mario bros, but mario escapes chernobyl

Mario Is cursed 0:55

Nintendo should hire you bro, seriously

0:39 WHAT

1:24 Mario dies steeping on acid water.

The funniest ending with 3 mario heads, so good, best idea ever

Could not stop laughing at the end when Mario's heads multiplied Did everyone enjoy the Super Mario Bros Movie?

0:39 mario with 3 hands

This looks like a good Mario Maker level.

Imagine Luigi in this level, he'd be extra stretchy after he was finished.

Alt title: mario but he got teleported inside twitter

Lets get real, this guy never fails to entertain us!

Mario litteraly mutating is the best part.

I have to say, their animations improve and add a lot of Mario Bros items that even Nintendo wasn't able to do, every video on this channel I see something different, it's really cool, it even looks like they updated Mario Maker at areally advanced level, the Level Up channel has a very good and special talent in animations :)

I haven't played a single Mario Maker level in those games, but if you ever made these in Super Mario Maker 2, I'd buy the game and play your levels. Seriously! Your levels and creativity are top-notch. Kudos to you, LevelUp!

I have two complains about this video. 1. I wish it was longer, for Marios suffering sake. 2. I wish more Mario radioactive enemies and more Goomba interaction.

Imagine if for the next 2D Mario Platformer, they make more levels in the style of these videos.

I really hope they add something like this into Super Mario Maker 3. There are so many ideas they can capitalize on.

Mario's pretty tough to not die instantly being even half a mile from all those rads lol

Makes me wonder if there is an exclusive protective radioactive suit power up for Mario to help him through this stage level a whole lot better.

That is heavily creative, the who radioactive concept. I especially loved the meter at the top, as it increases just by the presents of being by the thing, and if it is massive jump man just evaporate just by being near it.

1:49 nothing he could do, but twerk uwu

poor mario. In like the past year he has "survived" a nuclear apocalypse, a zombie apocalypse, I think a hostile takeover by a "competent" bowser army, and pretty much every horror imaginable. Gotta admire the commitment to these "what if" scenarios for mario.

2:14 now the adventure starts 🤟🤘

Never Out of Ideas. That's Why the channel is great

This and the zombie apocalypse ideas are actually really good ones to go with. These would definitely make level designs and gameplay in official Mario games more interesting.

All I can think of is playing the Imagine Dragons song Radioactive

Who would be worse as an irradiated villain? Bowser, Wart, or Birdo? Either way, this was great. Loved the Fallout reference with the rad gauge.

If there were a spider in here and it bit mario, would he be able to shoot webs from his hands and swing from pillar to pillar? 😅

When I first saw this video I thought “I can’t wait for Mario to grow 2 more heads!” Now imagine my surprise at the end of the video

Bro turned into the wither at the end 💀💀💀

This is one of your best, yet. This one was awesomely unique in so many ways.

Mario at the end became a human cerberus. 😂

I love the detail changes when the radioactive waste affects Mario by changing his body!

1:11 I saw them first in the liquid nitrogen video, but there is something amazing about those forward facing liquid dumping pipes.

Nice job Mario getting through this radioactive course

That radioactive King Bill is something that I didn't expect, and I love it already.

love how you gave mario a radiation bar, really makes for some close calls

Another Epic Mario encounter! The part with the rapid tower ascension before that massive bullet bill collapsed it made me think of something out of a TR game!🙂

I like how this introduces a new game mechanic: Radiation Level

Nintendo should ABSOLUTELY hire this guy! I love the animations this guy makes! Also I was sorta expecting some sort of big mutated Koopa fight at the end, but the giant radioactive Banzai Bill works. (There needs to be another one of these made, maybe with a bit of help. That would be cool!)

The segment with the Nuclear Giga-Banzai Bill crashing into the tower reminded me of the Skull Tower level in Kirby Mass Attack, specifically the parts where the giant stone fists punched into the tower walls and threatened to knock the whole thing over. Allowing them to do so, of course, meant instant death for your whole crew of Kirbies.

Can't imagine what Radioactive Bowser would be like. That would make the boss fight a lot harder.

Wouldn't wanna live in a world like this...

Ah yes, radiation sickness. No amount of 1-ups can save you from that.

Really cool variation

Death tips: -Those barrels are labelled radioactive for a reason. Also, note the rad count. It fills, you die. -Didn't you think that a heavy thing plunging into the hot stuff would splash it on you? -Don't ask me who made that trap bridge. I'm just the snarky tip giver. -Couldn't you see the radioactive waste spouts? Time your jumps! -Slogging through even the shallowest waste pool is going to irradiate you real fast. -Uranium Bills are HOT. Do not get any closer than you have to. -You might wanna be a little faster on the ascent, because BOY, that Uranium King Bill is HOT HOT HOT! -Might not want to get distracted with climbing, even if the coins are isotonic.

2:51 Mario : Here we go! *Two Mario heads* -go go! Mario : Uh uh uh oh oh oh! Daryl Lee : You win but your Radiation is too high!

Forget gold goomba, tiny mario head is the best character ever

King has returned

Mario: NOW I AM RADIOACTIVE THAT CAN'T BE GOOD!

It's Radioactive but reminds of Ecto Cooler drink. Lol

This video is so amazing that the only way to improve it is to make the enemies also get mutations once in a while

Mario is growing new body parts. 😅😂 that’s so funny By the way, great video.

Best animation yet by level up

By far the most creative work yet! I loved literally everything about this! Welcome to the "Ned's Mind Blowers" playlist!

Bro He Stepped On A Radioactive Bucket Metal Stairs 0:50

I was really expecting the enemies to turn into mutants when they become radioactive too.

Oh my gosh! Seeing how Mario could go through this Radioactive disaster, it was a very good Mario video!

2:36 Mario's greed got to him

Level ups artwork just gets better and better!

This was a really neat concept, I love the implementation of a radioactivity bar

One of the scariest Level Up videos imo

I would love to see a zombie apocalypse on that radioactive waste.

I got scared when Mario got extra arms and a leg! Imagine getting radioactive acid splashed on you and you gain extra arms and a leg?

This level caught my attention, especially because of Mario's radioactivity meter.

I like the idea of coins able to reduce the radiation, Very creative

Well Whats Next The Floor will be quicksand? Lol

Ah yes, Nuclear Nick. Also known as Warhead Will, Atomic Andy, H Bomb Henry, Radioactive Randy, I could go on

This looks absolutely Amazing! I like how he grew two more heads when he pass the Level. Your videos are so Fun to watch, I would love to play this in a Actual Mario Game! 🔥

2:51 Mario: Here we GO- (Gets more heads) Head 1: GO- Head 2: GO- All: Uh oh

This deserves a sequel ngl

I feel like this video sends out a message. “Only YOU can prevent radiation poisoning.”

The radioactive waste comes from Illumination. Your parodies are more fun than their Mario movie.

And that’s why you shouldn’t dump radiation anywhere.

Radioactive? That's way worse than normal acid! 0:34, 1:22, 1:23 and 1:24: DANGER! (1:25) 1:59, 2:00, 2:01 and 2:04: Tiny Mario is back! 2:11, 2:12, 2:16, 2:17 and 2:19: RUN! 2:25: Mario lost a life and Tiny Mario leaves! Bye-bye! (2:30 and 2:36) 2:49, 2:50, 2:51, 2:52, 2:53 and 2:56: TIME UP! (2:57)

This is why we never mess with radioactive chemicals, kids.

Fallout Mario would be a pretty interesting game.

0:57 "He has two left feet."

Bowser + Immortality + Radioactive Waste = Godzilla

I love that Mario had three heads at the end and all said uh oh
