Basket picks up in the cave off the abandoned mineshaft, still chasing the zombie noises from last time. The hope is a spawner, because a spawner would "sort of influence where we are going to set up our main base." For a moment Basket thinks there's no sword in the inventory, then: "I feel like we have another sword. Yep, good."
Just two zombies
The noise turns out to be two zombies walking down a passage. "Could that be a spawner? Maybe, maybe? No. Just two zombies." The tunnel loops back to where Basket started, so nothing was missed. The iron is adding up, "about 50 iron from so far," but the way back to the mineshaft is fuzzy. Basket isn't worried: there's the surface and a ladder to find, and the base camp doesn't hold much anyway.
A whole party
"There's the enderman," Basket says, and tries not to look at it, "because he would end me pretty quick." Hoping for diamonds, Basket heads into a lower part of the cave, lights it with torches and finds lava and water spilling down the rock. A zombie and a creeper come at the same time. "Oh, creeper, look at that. It's a whole party." Further in, the cave fills up with mobs: spiders, more zombies and something carrying an enchanted bow: "Oh, enchanted bow! You gonna drop them for me?" "Lots of bad guys in this cave." Basket fights through them. Basket is at experience level 20 by now, enough to think about "a pretty good enchant" later.
Smelting break
With the pickaxe running low, Basket sets up shop on the cave floor. Three furnaces go in next to a crafting table, and the iron goes in "in three stacks just to save on time because we have plenty of coal." A bow turned up from one of the fights: "Oh, we did get a bow from somebody." While the iron cooks, Basket crafts the missing piece of armor, "we need a chest piece still," plus iron pickaxes, "I feel like we've graduated from stone picks," and a spare sword. A creeper spawns nearby during the wait, and Basket goes after it. "He died pretty quick, actually." Then there's another creeper to deal with.
Iron for days
There's more iron in the next stretch of cave, "whole lots of iron," and the path leads back to the mineshaft, where a zombie is "carrying some gravel. Silly guy." The new chestplate has been sitting in the inventory the whole time: "Oh, what is this doing in my inventory?" It goes on, and the armor bar fills out. No diamonds yet, "but we'll have our time." The base camp is still lost: "I have no idea where our base camp is, we kind of lost it, but I'm sure we'll run into it somewhere."
The poisonous kind
Basket is "really nervous about running into a cave spider nest." A big room in the mineshaft is open on top, so Basket seals it with cobblestone to stop things dropping in. Then come the spider sounds. "What kind of spider are you? Oh, you're the poisonous kind." A cave spider bites, the hearts go green with poison, and Basket kills it. "Just the one." Going in after more is a hard call in hardcore: "I don't know if it's worth it. Probably isn't worth it." Basket blocks the passage instead. "There you go, all to yourself. You can just have that area over there."
Next time
The worry is that the spiders will pile up behind the wall and come looking later, but for now Basket feels "pretty safe with a bunch of spiders to our back." The episode ends there, with Basket alive in the mineshaft and plans to keep exploring for "a chest or maybe some diamonds or gold."
