They pick up right where they left off, in a safe spot they walled in with blocks. Straight ahead is probably the wool. Also straight ahead: "a bunch of wither skeletons and stuff."
Settling in
Before any fighting, one of them has to fix their settings. After a Windows update the game has them left handed, and the view bobbing needs turning off. "Right hand! There we go." One of them also has most of their stuff back.
The list of things to watch out for is long. Bow guys, because they knock you off things. Wither skeletons. And magma cubes, which come from spawners they think are somewhere above their heads. "Can I just say I hate creams?" "They're like the paper cut of Minecraft mods." Half a health bar goes with every hit.
Visual confirmation
There's a creeper spawner up there too, and a wither skeleton spawner right above where they're standing. "I have visual confirmation the very not good stuff is right there." The good news is that the lava below seems to be gone.
The wool turns out not to be hanging in a cage in the middle of the room, which is what one of them pictured. It's on a platform in the far wall. "I thought we were going to like a bird cage in the middle of the room." Ender pearls come up as an option. The plan that wins doesn't use any.
Bridges and tunnels
So one of them builds "an upstairs bridge to get over there. Not the most exciting thing in the world." The other one goes for a look and finds a whole other room of trouble: four or five regular creepers and one charged creeper, right next to a wall. "That's what made me decide to get out of there."
Then comes the wither. "Oh god, I got withered." There's a mix-up at the top of a ladder too, where one of them blocks the way just as the other is trying to come through. "I will not assume blame for anyone."
Inside the wool box
The tunnel works. "Alright, I'm in the wool box." The spawner on top of it is gone, and there are two creeper spawners up high on either side. For a second the other one thinks the wool is already in hand. It isn't, yet. Then: "Sweet, got it."
On the way out they check "the art supply chest" in the back. It's a treasure chest full of stuff, so they split it up: magma cream, the diamond gear, "the magicky bow," a shield, arrows and experience bottles. The arrows matter, because one of them doesn't have Infinity anymore. There's also "another chest full of magic books."
Finding the way out
Getting out is its own problem. "The only way I've gotten out of it successfully is to die," one of them says. "Which I don't recommend." There's also still the other wool to find, and one of them guesses it has something to do with the planets.
Right at the end comes a discovery. "You know what dude, I had music playing this whole time."
