The title is the whole plan. They head into the red glass area, a level of netherrack, lava, blazes and magma cubes, with zombie pigmen walking around who aren't angry yet. The goal is to keep it that way. It doesn't last.
The one rule
"I hope you didn't think that was the actual magma chamber. If you did, you need to know me a little better." There's a pigman, not angry yet. "So don't hit any pigman. Don't use your sword." The pigmen come from a spawner in the wall, so there are probably more spawners hidden behind the magma blocks.
One of them has a plan: pour water down to put out the lava, because there's a blaze spawner below. "Spawner down." "I'm an expert spawner breaker." The bow is a worry, though. A stray arrow could hit a pigman. Not long after, one of them gets down to one heart and nearly dives into lava. "It's not a healthy reaction."
Blazes, magma cubes and a record
The record gets picked up early ("Yeah, I have the record"), and the water does double duty, pushing mobs down into their own pit. "It's an expert trap job." The magma cubes drop magma cream, and somebody asks whether they should keep one of the spawners. The answer comes from someone in the middle of a fight: "I'm battling Blazes right now. Quit asking me questions."
Fire Aspect and Flame on the record are no help here. There's a chest with an Efficiency pickaxe, 13 magma creams so far, and diamonds that a gold pickaxe can't mine. "Gold doesn't break diamond." Someone wonders if there's a hidden emerald down here.
The punch
Then the rule breaks. "I hit him with a record." "Are they mad at me? Oh, they're mad at me." The death screen reads "BasketMC was slain by Zombie Pigman." Now the whole group is mad. The fix is to run far enough away that they despawn and forgive you, which leaves Basket's gear sitting in the middle of them. One of them uses the wait to work on lyrics for a "pigmen going to kill me" song.
It sort of works. "Pigman is my friend. I went up and got next to one." Then a second death line, "BasketMC was slain by Zombie," and now there are two death piles. The other one picks up part of the first pile, and some pants are still out there. "I feel like in the last episode you made fun of me for dying." "I did."
Skeletons on fire
Past the next ridge there are "special guys": skeletons with a funny-looking head, on fire, shooting flame arrows that set you on fire too. The arrows they shoot are infinite and don't go away. One of them takes a shovel, a pickaxe, arrows and a combat bed from a spare chest.
There's a chest at the bottom of a big pit, with a blaze spawner around it. Working from the bottom of the pit ends with "BasketMC was fireballed by Blaze." Back in the level, Basket is still burning and water won't put it out. "Something weird is going on, that's all I know." Maybe lag.
Starting over, mostly
To get the mobs to despawn, they go all the way back to the start. "This level is not good." On the walk back in: "We probably should have ended that episode." "Why?" "Because then you wouldn't have died till the next episode."
The water from that last death runs right up to the edge of the lava, so whatever was in it is probably gone. "I have arrows, no bow, no pickaxe." The other one may have the bow and put it in the chest. Then a creeper shows up behind them, someone handles it, and "Saved your life" closes it out.
