The episode opens in a hurry: skeletons, an Enderman that is mad at both of them, and one of them a very long way from where they need to be. By the end the white wool is in the monument and they are counting what's left.
What a way to start
Basket drops into water to get away from the Enderman, and someone pleads with it: "Please just forgive me." A water bucket gets thrown in the panic. Meanwhile one of them has to come all the way back from the start of the map, "back up to the jolly old land of Oz with all the emeralds." The directions are simple: take the regular way, and once you hit the iron section, head down.
"What a way to start an episode." "Professional Minecrafters. Always winning, never dying."
There's a short hunt for a lost helmet, iron or maybe chain mail. Nobody can find it. Then it turns up in the owner's own inventory. "I hid it in the safest place."
Bed set
Next they reset spawn. A bed goes down somewhere off the bridge, and right as one of them gets in it, a creeper falls off one of the coal pillars. "Okay, that was exciting." Bed set, they head across the bridge.
On the other side is a quad spawner that is "so full it's not good," with the coal head and gold head mobs. The gold guy is fast. "Where did you come from, where did you go, where did you come from, golden head Joe?" One goes down and they look for the second. "Careful, it's raining gold."
Sorting out
The treasure chest on the glowstone gets cleared out, down to an Unbreaking III book. Basket uses an anvil to combine two iron pickaxes and ends up with one carrying Efficiency IV and Unbreaking. There aren't enough levels left to fix up a sword too.
Basket takes a coffee break in the middle of a song. Then: "Let's make like a tree and get out of here." "Let's put an egg in our shoe and beat it."
White wool
The wool was where they guessed, in the middle bottom of the area, near the bridge from last episode. "White wool! Woo!" One of them has it, and they head off.
The emerald is a bigger problem. They aren't even sure if this section has one emerald or two. One of them spots a sea lantern up in a pillar, then an emerald pillar that seems worth a look, and there's an emerald block high up past "this stupid magma box," in a spot full of bad stuff. The way to the next section hasn't turned up either. The plan is to drop off the wool first and come back for the nasty part. "As pro Minecrafters, you know, we've got to be willing to do the hard stuff."
Back at the monument
At the monument the white wool goes into its glass pillar, with Scoti standing right beside it. By their count there are four wools left, and brown isn't done yet. Then they sign off.
