An obsidian floor full of ghasts, blazes and creepers that drop from the ledge above, a ladder plan, and two players who get tangled on the same ladder.
Basket closes off the side passages at the bottom of the iron farm base, takes the beacons down for good, and starts copying the slime platform's pattern onto another corner.
An ender pearl gets them into the hanging emerald box, two named weapons turn up in the invisible maze, and an enderman sends Basket back to the start.
More of the barrier block level: a chest of magic books, a labyrinth of invisible walls, a creeper that gets Scoti, and a chest of enchanting tables and anvils.
Basket shifts the last stair path in the iron farm base over one block, rebuilds the hoppers under it, adds ladders for anyone who falls, and gives a tour of the whole base.
A level of floating floors and invisible walls, the wool in plain sight and out of reach, a friendly-fire arrow, and a helmet called the Depth Plunger.
Basket lines the water channels at the bottom of the iron farm base with sea lanterns and white glass, then moves a whole path over by one block, hoppers and all.
The slimes still won't drown, so Basket swaps the water for magma blocks with hopper minecarts underneath, then learns the hard way that carts on curved rails go everywhere.
A room of little platforms over the water, a floor that blows up underneath them, an emerald through a hole, and a death that sends Scoti back to the start of the level.
Into the structure at the bottom of the lake: a drowning, openings that can't be blocked, a sponge to push the water back, and a surprise birthday pizza for Basket.
Basket tries hopper minecarts a new way, gets the item portal at the bottom of the iron farm base working, then starts a hopper line through the Nether toward the hub.
A new cave of pink trees and glass-covered coral, a chest of Depth Strider boots under the water, skeleton spawners hidden in the flowers, and an emerald out on the lake.
