It opens with a message for renderXR: "This isn't very hard. We're really good at your levels and nobody died ever." Then they're back at the monument, and one of them has "the gray." The plan from here: two more emeralds in the area they're working on, then the black wool and the black wool emerald.
Planets in the dark
The area is a set of block planets hanging in a starry sky around a big orange sun. Getting from one to another is the puzzle. One of them has a bunch of wood and turns it into ladders, so they don't both waste stacks of blocks pillaring up. Can you put ladders on glass? "I think the answer is no." So the pillar starts as cobblestone.
There's a warning about arrow guys, and a joke that goes wrong halfway through. "Make a elementary school student and get a book. Or get a pizza. Sorry, first don't get a pizza. I messed up my own joke."
Picking a planet
They look around. One planet has a hole in it. There's a little box "like a little tiny moon," a planet with lava on top, and one "like Saturn over there" that turns out to have TNT. A planet above them has an opening, and the guess is "there's probably charged creepers and an emerald" inside. They go for the green one first, with the ladders on the back side.
Inside the green planet
At the top there's a creeper and a spider, so a lip goes up over their heads. Looking in is worse. "There's a lot of bad guys in there." Zombies come, then a creeper, then "a lot of stuff." There's at least one spawner in the middle of the room and witches on top.
Then a creeper gets Basket. "BasketMC was blown up by Creeper." The other one grabs what they can: "There's guys with your stuff." "I got your sword." Basket runs back from the start and gets the potatoes, which were "on lockdown," plus ender pearls and a chest of gear. They decide the mobs up there were natural spawns after all, witches and all.
A zombie with good timing
Now it's the other one's turn. They tried a water bucket to push the mobs back. "It kind of worked until it did not. The zombies were swimming up it." Then a zombie jumped up and knocked them off. The shield went with them, the one with 22% knockback resistance. "Now you're gonna have to be good at Minecraft again."
What's down there? "Probably like 40 or 50 mobs." Creepers, maybe two kinds of spiders, zombies. Nothing special that anyone can confirm. They name it something we won't repeat here.
Regrouping
Back at the chests, they work out what to bring. TNT, maybe, and attack from above. A friend. Getting the lost gear back is called "a pipe dream," and there's a bow that can't be repaired right now. The coal is nearly gone too, so some goes into a chest "so I don't lose it all when I die."
"Let's go get them back." And that's the episode.
