"Yeah, we definitely haven't been here." Still on the level of block planets floating in space, they land somewhere new. It's mostly creepers, plus guys with bows, and somebody shoots an arrow up from below. There are Endermen around too. "I almost looked at one."
Four spawners in a box
Past a skeleton and a creeper there's an opening, and the hope is that it leads to the next area. What's inside is a box with an obsidian roof and four spawners stacked on top of each other's blocks. One of them can drop onto a spawner and break it right away, so that's the plan. "I saved your life." Then: "One spawner down, good job, the plan kind of worked."
A mouse and a pickaxe
The skeleton spawner is the one left. One of them gets right above it and then finds the mouse button isn't working. "That may have been my problem this whole time." Next comes slow digging through obsidian with an iron pickaxe, until the other one points out there's a diamond pickaxe in that inventory. "Then why wouldn't you just dig?"
The spawners all go down. At the bottom there's a glass floor with an arrow under it, pointing to where one of them is standing. They think it's there so people looking down can see the spot. "Expert Minecraft."
A new area
"All right, I'm in new level." Nobody wants to go far, "'cause something bad'll happen." There's no teleporter, so a water bucket goes down at the back to get in and out. An Enderman stands behind one of them, thinking things over. They check under the floor for anything secret. There isn't.
A hallway with purple walls leads to a room with a shulker box in it. Inside: a stick. There's also sand in the middle of the room, which shouldn't be there. Someone runs across it and sets something off. Holes open up, the call is to block the whole thing up, and the mouse button fails again. "We should have a GoFundMe for your mouse."
Not out of planets
They still need to go get one emerald, and find the other one. One of them figures they're out of planets, so it must be inside the sun. "We're not out of planets!" There are two they haven't been to. One looks small, and that gets a lecture: "Big things come in small packages."
That one has spawners, lots of arrow guys, and a bottom made of sand. "Don't get shot off the planet." The plan is to drop TNT on the spawners, and that's where it ends.
