Welcome to the room of doom. This is the other platforms room from last time, and by the end of the episode the sunken level has given up its wool.
Hug the wall
The most effective way around, one of them has found, is the wall. If the skeletons shoot you there, they're just knocking you into the wall. The other goes along the back wall to shoot from there and try not to die, and the idea is almost good. He didn't count on how many there were below or how much they'd shoot him, so he retreats while the skeletons at the bottom get thinned out.
Once all the platforms up top are torched, one has a chest that isn't trapped. It's full of books. One of them barely has room. There are experience bottles too. Up top there's an opening they agree to remember. More witches, a ladder that's probably a shortcut, and a chest by it. They put a bed down there, even though it'll probably get destroyed.
Whack-a-creeper
Behind the wall is a room with a caged pedestal in the middle, set in the water with platforms around it. There are creeper spawners in the corners and a ton of creepers, a regular skeleton spawner, and a special skeleton spawner right in front of the cage. Blazes come from a spawner up in the roof at the back. The creepers bob up and down in the water, which makes shooting them a minigame. Somebody in the chat calls it whack-a-creeper.
Blown up
Then the chat reads Scoti_Garbidis was blown up by Creeper. That's why they put the bed down. He gets back to his stuff with blazes hanging around it. He gets some of it, and the emerald he was carrying, which he says he probably should have put down.
Cyan
Cyan, cool, man. The cyan wool is theirs, and a chest holds gold picks and 64 ladders. They dig and ladder their way out, which takes them back to their room. One emerald is on them and another is in the chest at the start of the level. There might be more chests and emeralds in here, but they retreat.
On the way, they make sure somebody actually grabbed the wool. Didn't they once leave without one because each thought the other had it? Yes. It was green.
On the monument
At the monument the cyan wool goes on. Basket puts in emeralds 30 and 27, and there's talk of finally making an iron block. That leaves four wools: gray, light gray, white and brown. They wonder whether the levels connect in some order. Black was the last one, but the area connected to it didn't hold gray.
Then it's a food break.
