I made a Transforming Cave Base in Minecraft

“How did you get so strong?” “Every time Mumbo Jumbo says ‘piston feed tape,’ I do one push up.”

11:04 I like the fact that Mumbo spent a lot of time figuring out how to pop up the crafting table on the corner when there are already 2 crafting tables implemented on the wall beside it.

Mumbo: Everything about this is satisfying! Also Mumbo: A few hours of repeatedly smashing my head into my desk

This is one of those videos where Grian needs to do the voice over as I'm sure that he can explain double-piston extender piston feedtapes with no issues whatsoever...

Alt title: *Mumbo jumbo speaks minecraft enchanting table for 12 minutes straight*

Mumbo: You would never suspect anything about this cave! Also mumbo: *making a cave with slabs*

Dang Mumbo, not only is it incredibly functional, both modes look absolutely amazing. The use of the stonecutters, brewing stands, hoppers, and backlighting really add a lot of depth to an otherwise flat build, and the color palette is warm and inviting. Good show!

"I feel bad for anyone watching this that doesn't understand redstone. It's just words." Yeah, mumbo, that's why I watch. I sit my dumb little butt down and I watch you do magic tricks for 12 minutes and then I applaud and go make a dirt hut. Edit: Gonna add /gen to this bc I don't want anyone thinking I'm tryina be a smartass lol

Mumbo Jumbo: *explaining complex redstone* Everyone who doesn’t understand redstone: I like your funny words, magic man!

Id like to imagine the inside of Mumbo's head is just a floor full of pressure plates and chickens. I don't know how else to explain this redstone insanity occuring.

I admire Mumbo's patience a lot, cos i spent 3 hours trying to figure out how to make a contraption work and now i wont go near the stuff for the life of me.

"I am not a builder" Well, that was a lie. Honestly, you have improved so much!

Imagine doing something like this, walk up to someone and say: "Please walk into my office" and then you transform an entire cave into an office. That must be the biggest way to impress anyone you try to do business with

5 years later, Mumbo makes himself a larger, significantly more extravagant, transforming cave base. Redstone remains almost the same size. Well done, MJ. Well done. They are gonna have to consider movable tile entity parity for Java, because it's a bummer to have to mod for something like this.

Can we take a second and appreciate how Mumbo can see how all of the blocks are going to interact BEFORE he places them? A true savant at his craft(ba dun tss).

boatem: exploding with ravengers and death mumbo: this redstone cave looks gooood

"See! I told you there was something here!" "You're right Candice, what a lovely little cave. Why don't you come inside and get some apple juice?" "Bu- bu- bu- bu-"

After being called a genuine builder in the last hermitcraft episode, it appears Mumbo had to retaliate.

Mumbo: "I'm surprised this still works. I built this way back in 2017. That's almost 5 years ago!" Me: 2017 wasn't that long ago its only been....oh my God.

“It’s not that I don’t have faith in myself, it’s just that I don’t really have faith in myself.” -Mumbo 2021 Literally the most true sentence ever for everyone who does redstone

I feel like each mumbo video is just an existential crisis on how mumbo claims he isnt a minecraft builder but just a redstoner

One of the best things about watching Mumbo’s videos is how much he genuinely enjoys every project. Like, you can hear how much fun he has every time, and it’s so nice to watch :)

“Piston feedtapes.” Now say it ten times faster. Mumbo: Hold my beer.

Honestly, this little project really goes to show Mumbo's growth. I remember watching the previous one, and how much he was struggling with each component, whereas now things came a lot more naturally to him. It also has to do with newer components that weren't there back in the day, but at the same time it does take some creativity to figure out how to put them together. It's honestly amazing

I have no clue what he’s talking about with the red stone but he still makes it very entertaining to watch

Mumbo, have you ever thought about using a texture pack that extends the slime on sticky pistons to the sides as well? It might help people to understand how to build these a bit easier, especially those who are new to redstone, or Minecraft as a whole.

I love how he describes all the things he does while doing it, even thought he knows we won't understand a bit.

Honestly, this is the coolest thing ever. The fact that it looks sooo much like an actual cave makes it that much more epic and surprising when it transforms. I love this so much!

Sometimes I forget that Mumbo is actually a genius engineer, and then he posts an occasional redstone video. And then I remember how many brain cells this man actually has.

This is why non Redstone people believe Redstone is hard and confusing. Even after a decent bit of actually watching you construct it, you still have no idea how it turned in to this Redstone monstrosity. Brilliant.

2:53-3:00 That's like... 80% of Mumbo working with Redstone. I've been watching these videos for years, and have yet to comprehend how t-flips even work. But they're so interesting, I can't stop watching.

Mumbo: “I feel bad for anyone watching who doesn’t understand red stone” Me: well I thought I understood but now I’m not sure

Easy way of torturing Mumbo: Make him build this in survival mode.

Yes! This is the kind of redstone videos I love coming from you! Please do more overly complicated systems that do things like this!

This just makes me jealous that we can't have moveable tile entities in Java.

"I feel like I'm so old now" - the youngest member of hermitcraft

Just a question: Would this somehow be implanted into your Hermitcraft base? And if so, can we have your office transform? If you still get to be CEO.

My favorite genre of mumbo videos is where he says tons of words I don't understand and then suddenly something works and looks cool

I would like to take a moment to admire the thumbnail. The emotion conveyed with the player head rotation downward, followed by a seconds rotation and the classic exclamation point. 10/10

Not gonna lie I think mumbos patience is amazing on how he spends ages trying to make a redstone contraption and that he doesn't give up. Well done Mumbo!

simple, really.

I would be interested in seeing you make this with a Redstone mod called, Project Red. I'd also be interested in your thoughts on Integrated Dynamics (a wire-based logic system).

Mumbo: insane transforming cave Me: 2 by 1 door Then I get more excited when its complete

We all felt it when he said “I feel so sorry for you guys that don’t understand redstone “

Mumbo: "And, I'm already confused." Everyone: "You took the words right out of my mouth."

Mumbo: just a few bits of piston feedtapes All non redstoners: what.... my brain is ded now

I love mumbo bc he has the ability to look at the most confusing machine I've ever seen in my entire and say ''It's pretty simple!''

If i had a dollar for everytime mumbo said piston feed tape, i’d probably have more than 3 dollars

Summary of this video: Mumbo saying “piston feed tape” and congratulating himself for 12 minutes whilst smashing his head into his desk at the same time. This is quality content!

I’ve been binge watching these videos, and even though I don’t understand redstone and haven’t played Minecraft in such a long time, it is much better than finishing the homework between school and my weekend, and I won’t regret this xD I might even fix my storage issues to redownload Minecraft…

"I could look at this all day" Well... given how you just did, to make this, I'm really glad you can.

This is such a cool build, I'm glad you're going back to your old videos and updating them!

alternative title: mumbo just trying to break the world record of saying piston feed tape in one video

"I have just two more piston feedtapes to build and then you will never have to hear me say that word again" Famous last words

Mumbo's next Last Life base be like: Thank you for acknowledging that some of us haven't the foggiest what you're on about when you're talking about the technical bits of Redstone. I personally enjoy you and how genuinely jazzed you are at the start with a new idea and how ecstatic you are by the end when it all comes together. You even leave in the bits during the middle where you're exasperated. *That* is what I love about your videos. You never try to convince us you know what you're doing, you just do it.

"oh i remember he making this transforming caven it wasnt that long ago" Mumbo: i made this 5 years ago WHAT? Mumbo: Im feeling old now Bro same

Alternate title: Redstone genius says "piston feed tape" for twelve minutes.

Me who was happy that I completed my 3 by 3 piston door and this muchstacheo man pops up with this, I mean its absolutely ridiculous, well done Mumbo, as usual :)

Mumbo's favourite saying *"it's really quite simple"*

Mumbo: I hope you can begin to understand what I'm doing here. Me: still trying to figure out what a piston is.

This is absolutely incredible! I can’t imagine how long this took, but I know it was worth a satisfaction at the end.

To be completely honest, I have no idea what Mumbo is saying half of the time- but these videos are always my favorite. They just honestly amaze me, that and they make me sleepy for some reason. But I just really enjoy these red stone vids.

Imagine having a hidden storage system like this where all the blocks are shulker boxes

What if Mumbo and Grian worked together to make a base. Grian would do the building of the outside and Mumbo can do the redstone, it would be so cool!

"...and after half an hour bashing my head against the desk..." Ah yes, the human way to think. Pandaros Excelsior

Mumbo: you will never have to hear piston feedtake again Also mumbo: says piston feedtake around 1000 more times during the video

I nearly had a mental brake down Whistle watching this

I had zero clue what he was taking about almost the whole time. But he is so entertaining and I watched the whole thing. Great job on the stone piston feeding tube thingy!

New Best Party Game: Every time mumbo says "Piston Feedtape" take a shot... Halfway through the video the party is at its peak

I was so confused when I saw this as I thought it was the one made in 2017 that I watched in 2020 because I have only consistently watching mumbo sin e then. I just decided to check the video out just in case. And this was so nostalgic. I can’t believe I watched this 2 years ago. That makes me feel old… and I’m only 13 so that’s just insane.

Mumbo: You could say its actually pretty simple. Me who doesnt even know how to make a 2x2 piston door: WHAT DO YOU MEAN ITS SIMPLE

Mumbo’s dedication never fails to amaze me

Any feeling I ever have that everything that can be discovered has already been discovered always goes right away when Mumbo makes something like this

Mumbo is the type of player that can pause an online game

Every now and then I think it would be cool to see the full process of him figuring out solutions for redstone that doesn't quite work. It blows my mind how he comes up with this stuff.

This is SO cool - imagine inviting someone into this unassuming little cave and then *bam,* it’s a fully functioning base!

2:53 I was literally just thinking to myself "I like your funny words magic man."

Mumbo: creates an machine that goes to border in 1 sec Also mumbo: *its simple*

For all of you that didn't ask, Mumbo said "piston feed tape" 37 times.

Mumbo: I'm surprised this still works, I built it way back in 2017. Me: that's not that long ago... Mumbo: that's almost _five years_ Me: (dawning realization) my god...

Mumbo’s transforming cave: Mega redstone contraption. My transforming cave: create mod

Me, who only understands the basics of redstone, watching mumbo's videos be like: i barely understand a word of what youre talking about but it all ends up looking pretty neat and i find that entertaining

"Its not that I don't have faith in myself... its just that I don't have faith in myself" Me literally every day lmao

YES, MORE TRANSFORMING OLD BUILDS INTO NEW AND IMPOROVED ONE'S ^-^

This is awesome. I am amazed at what you make. I honestly still can’t make a double piston extender, but I have been improving in my redstone

I love that you create a huge radical problem for yourself then let us watch you solve it.

Here's an idea: Pull the walls away with flying machines, then slide new ones in.

Mumbo must've spent ages on this build and it pays off. This looks so cool

Idea for the next redstone video: Remember a year ago where mumbo made a machine that made flying machines? well, I challenge mumbo to make a machine that makes TNT-flying machines. The magazine should also have an expandable design too, I'd love to see mumbo pull that off

I love the casual display of wealth as the room transforms

when mumbo gets confused about redstone, a reality SOMEWHERE collapses into a singularity

Fun fact: mumbo said piston or redstone feed tape 34 times.

Mumbo: And after half an hour of bashing my head against my desk Me: And after half an hour of repeating Mumbo's quote

This is insaaaaane!!!! One of the coolest things I've seen in the redstone department in some time!!

Mumbo most definitely is a builder by now but i’m pretty sure he’s gonna keep saying no because it’s his signature line at this point *and it annoys a lot of people* lol

I remember when this first came out, time flies by.

Mumbo: says smart redstone stuff Me: i like your funny words magic man!

Gosh, I remember when the original video came out and thinking that was super cool. Now this is BEYOND cool! You’ve outdone yourself again Mumbo!

I love it when young people say “I feel old”… thanks mumbo I now feel ancient!!! Lol
