Still in the jungle of giant trees. This one has a surprise in a chest, a lamp they're sure is a trap, an emerald next to some iron, and a pit with an emerald block in it that nobody can explain.
Gravel, finally
Some housekeeping first: they have a skeleton grinder now. Then it's back into the trees, past a spider jockey on a branch and a zombie that one of them won't shoot because the other is in the way.
A chest up top is full of building supplies. One of them opens it and finds gravel. "I feel like he intentionally didn't have any gravel the entire map, but he actually put some in there." They call it an oversight.
A shack for the bed
There's an opening in the water below, and a waterfall that drops into "a whole sub level." They don't agree on where to set spawn. One wants it up high so there are plenty of ways down. The other is "just going to go down." Down there, the spider spawners go first ("spider spawner down"), then one of them builds a little shack for the bed and they sleep. They light the top of the box, dirt the door shut, and go into the water.
The lamp on the bridge
Across a bridge is a small building with a chest, a spawner underneath, and a lit redstone lamp. That looks like a trap. One of them wants to grab the chest and run. The other explains the worry: "If a redstone lamp is lit but not actually powered, then activating the thing would potentially trigger an update." The lamp gets broken anyway. Nothing happens. The chest has torches and two golden apples.
Nearby there's an emerald, with a creeper following whoever goes for it. "Almost lost the emerald." Basket mines the iron around it while the area is quiet. They think there's one more emerald in this level. "One high and one low. I'm aware of the patterns."
A sick tree
One very tall tree has chests full of garbage and enchanted books. "This tree looks like it is ill." "Ill like good or ill like bad?" "Ill like sick." "Sick like good or sick like bad?" Another chest has a golden apple and arrows, and nobody is excited, since "we don't really use them."
An emerald block in a pit
Back on the ground there's a black obsidian spawner in one corner and a pit they haven't been in. The pit has two spider spawners, a chest, and an emerald block sitting on top. "Did you put that there?" Nobody did. The spiders attack through the ground. The chest has a helmet and books with Flame, Knockback and Feather Falling III. They decide the emerald block might be pointing them back toward the pit where they got the wool.
The phantom guy and a trap
They jump into the water to reach the obsidian spawner. It puts out a mob that "looks like a phantom" and swings an axe. Past it is coal and XP bottles, then a string trap and a rush of skeletons. "Trap, trap, trap!" "Expertly disarmed that trap." Nobody is sure what the string was supposed to set off.
A back cave has more iron, charged creepers and an ender chest. One of them is holding the emerald. "So I do." It feels like a shortcut, and like the end of the episode.
