I don't normally do intros like this, but I'm currently descending hundreds of feet into a cave that runs over five kilometers deep into the earth. And whether we like it or not, as soon as my friends and I touch the ground, we are officially... stranded here for the next seven days.
Stop! That might have been the scariest thing I've ever done. First things first, we gotta get really far away from where we rappelled down. Why?
If it storms, this entire area includes flash floods. Fill up like an ocean and put 10,000 potentially drown us all, which is why we're going deep into the cave to set up base camp. Whoa, this is just wicked.
Dude, this is like a different world. This cave entrance may be beautiful, but looks can be deceiving. We didn't know it yet, but the next seven days will by far be the hardest of our entire lives.
What is that? Yeah! All right, it's going to get dark in a couple hours.
If we don't have a camp, we're screwed, OK? Do you have any idea where you're going? We're just looking for flat ground to set up camp.
Upon entering the mouth of the cave, we stumbled upon an area with high enough elevation. elevation to protect us from any flash flooding, meaning that it was perfect for camp. Perfect is a crazy word.
Good enough is what I would use. Good enough for camp. We spent the rest of day one grabbing our supplies that we were dropped with. Each one of these bags weighs like 80 pounds.
And as you can see by the footage, we spent around four hours. This is very hard to traverse. Getting all of it back up to our base camp. All right, we've got some lights on in here.
Our supplies are finally at our home base. And if you point the camera over there, you'll see it's pitch black. It took all day. And so we set up the bare minimum for camping grounds. We drilled holes to hang up some ropes.
Grab these. Pull yourself up. Looks like the ropes will be able to support hammocks.
And with the help of our survival guide, Joel, we hung our hammocks. This thin rope is what holds up my hammock. Yeah.
Ate some dinner and prepared for a very cold night one. No, I can lie. This hammock is way more comfortable than I thought it would be.
Hey. Oh God Why is my head so big bro? This part of the cave is two and a half kilometers deep and we're basically camping at the entrance.
Tomorrow we have a lot of exploring How'd you guys sleep? Horribly. I didn't.
It's a very perplexing environment. The cave's constantly dripping water on us from above So we put a tarp over us, but even still the water's dripping into our hammocks. I have an idea Let's make our shelter actually good. I say we connect these tarps so we stay dry while we're sleeping. That's literally genius.
I'm not just a YouTuber, okay? My hammock gets out right here. Are we serious right now?
This is where I just got out of bed. And we didn't realize it at the time, but this hole is almost 40 feet deep. So while Sean and I got started on the supertarp, Mac and Carl went to see how dangerous this hole was for themselves.
Do you see my hammock up there? That is where I slept. Now look at this.
And because everything looks the same, and it's probably pretty hard to follow us in this cave, on this map, you can see our home base and how far they're moving away from it. All right, Mac. It's been real rough.
Oh, bro, this is crazy. While the boys are randomly exploring, me and Sean actually have to work on the camp. Why is there a sleeping bag over here?
Because it smelled like pee. Ew. Lesson number one, don't rent your sleeping bags. Why did we rent sleeping bags?
Why did we not just buy sleeping bags? We're zip-tying the tarps together to create one mega tarp. Don't mind me just trusting this rope with my life. And meanwhile, Mac and Carl, we're still in a hole. Oh my god.
And eventually, they finally made it to the bottom. Hey! We're supposed to be working on camp.
We just wanted to show how dangerous camp was. Just don't fall. It's a skill issue.
Oh, OK. And even though they should have been on their way back, Carl and Mac insisted on seeing how deep they could go. Bro, this just looks so crazy.
You think you could make it through the river? Little do these two know, this river actually runs throughout the entire cave, which means we'll be spending some time in it. Oh, there they are.
Tell me you guys cooked. Oh, we cooked. That's right. A new home, am I right? Let's go.
have a roof. Look at this. I'm not gonna lie, it's actually kinda gross. And we moved the fire pit to this little cove we found. What do you think?
It's warmer. It's cozy. These rocks trap the heat here and block the pee from the rocks above. It's not pee. What do I call it?
I don't know, maybe rain or something? It's not rain, it's rock. Maybe. Right, point it up. Do you see clouds?
No, you see rocks. It's not rain. Rock pee.
Rock pee. Rock P, fine. All right, it's Rock P. And after a much drier night of sleep, we decided to have Joel, our survival expert, help us get all the way to the end of the cave. Cave! Cave!
Cave! Cave! Cave!
Cave! to see how deep in the cave we can make it. Now, keep in mind, we are still just at the beginning of this massive cave, and our goal is to make it all the way through it, without dying, of course. Oh my gosh, this is kind of steep. Bro, you ain't seen nothing yet.
We're going deep in the cave. All right, boys, sucking you guts. This is where things get tight. I think I'm gonna fit!
The interesting part about cave exploration is one second you're barely fitting through cracks in the rocks Oh my god, this is so tiring. And then the next you're in a massive chamber so big that in order to see it all we had to do this. Woo! Oh my god! I can actually- I can actually see now.
This is awesome. This thing is bright. Woo!
Bro, look at how cool this is. Yeah! It's so bright, I can't even look at it.
I'm like getting blinded. Oh, no! Oh, no! In hindsight, we probably didn't use that the most effectively.
Lead the way. And so we continued on. Feel free, there's a really good handle at the top there.
And then you can sort of swing a foot around onto this one. Like this? Yeah, yeah, perfect.
Joel, the best caving guide ever. No one's died yet. Alright guys, this is where things get interesting.
What? What is this? So from this point on, wetsuits, we're going for a swim. Yesterday, Mac and Carl were joking about doing this, but the rest of this cave adventure takes place in a freezing river. Oh my gosh, this is insane!
Eating wetsuits are the only way to not get hypothermia. Why are we doing this? This is a once in a lifetime experience.
It's because you die after you do it. So in order to get to the end of the cave, we have to hop in this river and fight the rapids through this tiny hole in the rock and carefully squeeze our way through it. Take your time.
It will take your feet behind you a little bit. All right, I'm getting in the river. You want to follow the wall around. It's so cold.
You got it, Jimmy. Ah, I don't know if I fit. Jimmy, I need you to pull yourself up out of the water. The crazy thing about doing this is when you're completely submerged in freezing cold water gripping onto the rocks becomes incredibly hard. Oh my gosh, that was crazy!
Back! Carl, let's go! I'm scared!
You got this! Keep going! Look how crazy this is, dude. And even though this obstacle was difficult, it's nothing compared to what's up ahead.
We did it! Yes! Yes!
Yes! Yes! Yes!
Yes! We're now 10% done, which means we've only scratched the surface of this expedition And we still have over two kilometers remaining to reach the end. As you can see, it rains in this cave 24-7.
So I'm making a chill spot for us to hang out in and not get wet. I wonder what it would look like if I wasn't here to build all this. Pretty sure they'd just be sleeping in a pile on a wet rock.
The water would keep moving now that the bodies are wet. You got it! Temperatures are gonna drop quickly. Why is this so difficult? Ah, the worst part is every inch we go this way is an inch we gotta go that way to get back to camp.
Our next obstacle may be out of the water, but that doesn't make it any easier to get through. Oh, is that a spider web? Why?
I don't see a spider. That means it's probably on us. I hate my friends Just straight up if we didn't have Joel I'd be dead and after three hours Joel had some bad news for us What is too high and we've taken too long We're gonna have to turn around for tonight and head back to camp.
I disagree! You can't disagree with the safety expert! I disagree! Well, we can't really disagree. It turns out we wasted way too much time filming and playing with flares to the point where we now have to restart and attempt this mission another day.
Sean, we're back! What did you do while we were gone? Hopefully nobody gets wet now. I didn't even know we packed lights. Yeah, they're awesome, right?
Sadly, we only made it 20% through the cave today. But mark my words, we will go the distance in a future day. I doubt it.
That's not going to happen. We might rest on day four, and then on day five, try to go all the way to the end of the cave and see what's there. Day three was a lot of fun.
I'll see you guys tomorrow. And after a third miserable night in the cave, the next morning we only had one thing in mind. A hot shower would literally save my life right now. Oh, showering would be awesome. I haven't showered in three, four days.
As you can imagine, showering inside a cave. isn't easy. We had to hike all the way back to where we rappelled in to safely reach the riverbed. Oh my god!
I feel my brain. I've never felt my brain like this. My forehead is frostbite! Let's use the drone to dry our heads off. Come here, drone!
Hold on for a second, stop, stop! It's actually working. working. Yeah it is working. Who needs a hair dryer when you have a drone?
And after we dried off we sat down with Joel to plan our journey. What is this Joel? This is the map of the cave.
Last time we had to stop because of the fast moving water but the rains have been slowing so we might just get a window to reach the end by tomorrow. Dude this is about to be wild. First we'll need to pass some of those same rapids from yesterday, dive off massive cliffs and avoid jagged rocks and if we can make it past all that we will finally make it to the beautiful glowworm chamber.
Don't tell us what that that looks like I want us to be surprised. Do you think we're gonna make it? Whoa.
Nah, let's not play that game, we're all gonna make it. With tomorrow's plan thoroughly mapped out, we've rested up and made feastable s'mores to regain our energy. Everyone, cheers. Yippee! Oh, Joel's about to have his first Feastable s'more.
Alright Joel, be honest. Redwood. Joel approves? Joel prays.
Why didn't we whip this chocolate out earlier? This just got like ten times more fun. Guys, for real, if you've never tried s'mores with Feastables, you're really missing out.
Tomorrow, we're gonna explore the entire cave. We'll see you guys then. So we tried to sleep as much as we could and prepare for tomorrow's journey to the end of the cave.
We're about to embark on one of the most dangerous journeys of my life. Because of our experience from day three and focusing less on filming, we were able to make progress way faster. Woo!
The water's cold! Just like the other day, bro. Nice, bro. Easy. And to ensure our best chance of survival, in addition to Joel, we brought another survival expert with us.
This is where we had to stop on day three. How we doing? We're making much better time.
Behind us, it's pitch black. Where do we go? This area gets narrow, the current's strong. So we're going to use the walls and kind of climb our way along. Yep, here we go.
Jump for that first rock. There's a couple of good rocks around the corner as well you can get a hand on, so. It's so dark down here. There's no bottom right now.
My feet aren't touching the ground right now. Because we couldn't reach the ground, this meant that if we let go now, we could get swept away by the strong current directly beneath us. John, what are we doing?
I would go into here if you can. That's a good one. I can't even see where I'm going. The current is taking me away.
You got it. You got it. Get yourself through.
This might be the most insane thing we've ever done. We are much deeper in the cave than we've ever been. And we're now approaching our first serious obstacle.
Basically, the water's recirculating, so if you fall in, it takes you to the bottom and it keeps you there. If we fall, we would die. Yeah. Okay, so death is on the table?
This is just not what I thought I was signing up for. Yeah, perfect. Sign up for my script. Caving? It's a lot harder than I thought.
You can tell how strong this river is because it created this entire cave. And fun fact, we're not as strong as a cave. I'm barely as strong as a human.
Well, fortunately for us, rather than Carl leading this expedition, we've got the literal Avenger, Joel. And just to prove how much of an expert he is, this man literally flexed on us by jumping off a cliff. Whee! Oh my god! You're crazy!
Dude, I was just a bit crazy. Surely one of you guys are keen? I'm crazy! No shot you wanna do that.
What are you talking about? I'm doing it right now, baby! Let's go, Joel! Gotta speed back! After everything Jimmy's put me through...
This ain't that scary for me. Three, two, one... Woo! Are you doing it?
No, we gotta keep going or we won't hit the end. Oh my god. Can we go downstream?
Why are we always fighting the current? I might just start drifting away. I might just give it up.
There are sharp rocks underneath. the water you cannot see them so watch your step. Oh my god.
It's getting deep again. I can't. I need to put my feet on. And if the sharp rocks weren't enough of a challenge, it seemed like with every step we took... Oh, bro!
I can't see anything. This is terrifying. The cave became darker.
Tighter. And ruthless enough that we began to question if we could even get to the finish line. Oh, God!
This is awesome. This game is about to get a lot harder, and I have something I need to show all of you. Joel, can I see your bag?
Thank you. You know what you've been carrying? What have I been carrying?
The brand new Mr. V-slav Swarm. I'll be honest guys, as you can see, because of what I've been going through for the past five hours, I'm clearly in no shape to tell you about this right now. And so, a month after we filmed this, I built an entire cave set, threw on my Future Jimmy name tag, and then said, Hey, Future Jimmy here, and I'm gonna tell you about my brand new toy line up Mr. Beast Lab Swarms. It's a collectible toy line with over 119 uniquely designed characters that you can collect. And the coolest part is, to find out which character you got, you pour water into this tube, shake it up, and the swarms will appear in front of your very eyes.
And to demonstrate the product, I made this giant life-size version of the swarms tube. Fill the tube with water. You won't need this much water. This is just a giant tube. Alright, and now that this is filled with water, Mac's gonna give it a little shakeage.
Is it shaken up enough? I think it's shaken up enough. Then, you pour out the water.
Do the honors, Joel. And out of the water will be revealed which two swarms you got. This is the rarest one, the Hyperchrome, that I only made a thousand of.
Joel, you can have it. You can have that one. Who does Carl get? I only have two. If we didn't just stop with the swarms, we also made these action-speaker panthers that are in these briefcases and this mutator that just like the swarms has a really cool reveal when you buy it.
Where do I buy them? I'm glad you asked. Mr. Beast Lab toys are now available everywhere in the world you buy toys.
They're all out now, go give them a try. And after more brutal trekking throughout the cave, we finally arrived at the global Glow Worm Chamber. Man, this better be worth it.
Alrighty team, welcome to the Glow Worm Chamber. Whoa! Holy crap. That is crazy. Dude, this does not look like it's Earth.
All of the lights you see here are actually created by tiny bioluminescent glowworms. That kind of looks like the Milky Way galaxy. Wow. At this moment, this view honestly made that trek worth it.
While making it to the glowworms was definitely worth the trip, our journey was still not over, because we had to go all the way back to Base Camp. It's almost day six, they're not back and I'm exhausted. I don't know if I'll be able to sleep though Just worried with them being gone so long The trip back is way easier because we're just floating with the current Now because you guys have already seen the trip we're gonna expedite the way back But seriously this whole journey took so long we crossed into day six before reaching camp.
Sean! Sean! What's up guys? I was starting to get worried. Happy day six.
Day six, let's go. All we had energy to do was stall out by the fire and finally eat some food. That was a very adventurous day. I'll see you guys tomorrow or later today.
It is day six. Yeah, maybe today. I don't know.
Despite being physically obliterated from our excruciatingly long hike, no matter what I did, I was really struggling to fall asleep. I spent seven days in solitary confinement, seven days buried alive, seven days on a raft, and I'm gonna be honest, I think this is harder than all of those. You're constantly soggy and cold. I just keep hitting my body on these hard rocks, and it hurts.
90% of the time, this cave is miserable, but between me and you. Jimmy! Yo! Carl, can you see me? Ah!
Ah! It's the world's brightest flashlight. There are moments of fun in this cave.
Woo-hoo! From conquering rapids 300 feet underground When me and the boys laughing in our hammocks all the misery is worth it. Because when you're in good company Let's make whale noises.
this wet, cold, rocky, miserable cave can easily transform into the most beautiful trip of our lives. We cannot leave until everything is picked up. And when I say everything, I mean everything.
Let's get out of here. And after our journey back to the mouth of the cave, Oh, it looks so good up there. we had one more surprise for Joel.
And before we head out, Joel, as a show of gratitude, we got you 50,000 New Zealand dollars. So it's 10 grand for every human you didn't let die. Oh, gosh. Thanks so much, Joel.
We love you, Joel. And now that we got that out the way, let's leave. Woo! After seven long days, we're finally leaving. Yay!
