Something got built between episodes: a creeper grinder. After the tour, they finally go back to finish the spider cave, with a plan this time.
How the grinder works
It opens as another exciting episode of Where's Basket. Then the tour. You stand right here against the fence and the creepers spawn and try to path to you. With no water yet, they end up clumped together instead. Let them gather, up to 200 or so, then go down below with a junky stone sword and attack their feet.
The haul is gunpowder, a stack and a half of it, plus enchanted books, bottles o' enchanting, the odd TNT and a lot of XP. One of them confirms they do have Mending in this version, because his gold pickaxe has it. Some gunpowder and wood get handed over toward making a shield.
Do the pain in the butt thing first
There is plenty they could do today, but they never finished the spider area, so that comes first. Good advice, kids: if there is something you really don't want to do, do it first. They want to best the spiders in battle.
Comments pointed out what went wrong last time. They avoided breaking webs, ran in, and died in the webs. So the new plan is to break them, accept that things will spawn, and kill those few instead of trying to sprint in with torches. Right on cue, one of them gets stuck in a web while trying to jump sprint.
A second chicken
Back where they left off, the place with the silverfish where they died a couple of times, the webs come down. There is a second chicken. Don't kill the chicken if you can help it. They didn't kill the other one, probably.
The spiders spawn as soon as the webs go, so they back up and shoot. A spider drops a piece of steak. A pair of spawners go down, which one of them calls good teamwork. There are an awful lot of bats.
Steel wool and a tree
A horde of silverfish arrives, which one of them describes as little pieces of steel wool. There is some debate over whose fault that was. You did it, I blame you. Then a zombie spawner with max spawns and a baby zombie, and a witch that drops glowstone.
There is a tree growing in the middle of the cave. It is trapped: a tripwire up in the branches. One of them gets out in time and credits his Scoti instincts. One of them also notes that emerald 12 is in that thing back there.
Saving yourself mode
It ends in a scramble. A redstone torch turns up as the prize. One of them is stuck, being beaten up by skeletons, and asks whether anybody saved his stuff. The answer: he is currently in saving yourself mode. They agree that is the end of the episode.
