There's an air pocket and a spawner on top of the structure in the lake, which is where they start. Partway through, someone shows up at Basket's door.
Down the middle
The spawner on top goes quickly. Then it's in the front door, if there is one. Inside there's a guardian, creepers floating up from spawners at the bottom and the sides, and a skeleton spawner way down. No air pocket in there. The chat reads BasketMC drowned, and Scoti picks up his stuff. One of them likes this, because it means the other is catching up on deaths.
Every chamber has an opening, and there's something in the openings, barrier blocks maybe, so they can't be blocked up. What does work is blocking them from the outside. That leaves a big donut of blocks around the structure, and the only way in is down the very middle.
A sponge and a ladder
Down there they find a little air pocket and put torches around the wall. Somebody has a sponge. The space is three wide, so the water keeps replacing itself, but they narrow it and it works: no water on this side. Basket says good idea, Scoti, after being told he should acknowledge how awesome it was. They were probably both having it at the same time, he adds.
The result is a little ladder air pocket. Someone realizes a door would have made more sense than a ladder. On the other side of the wall there's at least a guardian.
Mossy halls
Past the water it opens into long hallways that look pretty trapped. There's a skeleton spawner on one side and creeper spawners on the other, then poison spiders, then witches behind a wall. In a previous level hallways like these shut the lights off, so they light everything up and clear one floor at a time. One of them blocks off a path. There's a chest with lights by it that might not be trapped, and nobody goes past the torches in case it is.
The water down here is hard to see through without anything magic, and there are no torches to breathe by. One of them ends up bobbing in a one-block air pocket. Saved your life, the other says. Nobody has to agree, but he can make that argument.
Pizza party
Basket steps away because somebody is at the house. While he's gone, Scoti tells the stream: it's a surprise for Basket's birthday, and he messed it up a little. Basket comes back. There was a car out front and he assumed somebody was trying to sell him something, maybe religion, so he didn't answer. Then the driver called.
Scoti apologizes. The half-and-half toppings came out wrong. Basket likes all of those toppings anyway, and figures he'll just eat the whole thing. Happy birthday, man. Scoti promises to get the toppings right next time. There's still a witch down the hall, but they call it there.
