Basket starts plotting the city walls around Basketopia in stone brick, with gatehouses, a tower on the harbor, a chain for boats and a spot for a quarry.
With a stack of bone blocks from the skeleton farm, Basket walks Basketopia and marks out where the roads, alleyways, buildings, harbors and a quarry will go.
Basket finishes the seams in a castle tower and hangs a pair of iron doors, then sculpts the ground behind the castle and lays a winding cobblestone path through the courtyard.
Basket finds the northeast tower isn't quite square, runs out of birch stairs on the ceiling trim, tops up tools at the XP farm, and lays out a plan for a flower shop in the village.
Basket puts cobblestone battlements on a tower, gives a tour of the farm under the ocean, then lays out rooms and secret doors inside the northeast tower.
Basket digs out the bottom of the northeast tower, then gives the inside edge of the castle walls a low cobblestone rail with torches, working out where the inner battlements should stop.
Basket digs the old dirt out of Basket Castle's northeast tower, breaks two shovels doing it, lays a new birch floor that lands at exactly the right height, and cuts one more window.
Basket finishes the windows at the top of the northeast tower, lays out a kitchen on the floor below, and brings big stairs down toward the tower's main door.
Basket puts a dark oak roof with a skylight hole on the northeast tower, then builds the empty inside from the top down: two balconies, a high-ceilinged banquet hall and dark oak railings.
Basket marks out floor heights in Basket Castle's northeast tower, matches its height to the other tower, squares off its corner, and gives it battlements and tall cobblestone wall columns.
Basket puts stairs and windows in the back tower, then runs a birch passage through the castle wall, adds a second level below it, and joins the two with stairs.
Basket refills on ender pearls, patches a missing birch floor in Basket Castle's northwest tower, and starts the battlement pattern around the tower's top.
Basket matches the battlement pattern on the far wall, lights it properly, raises a small tower with iron bar windows, and lays the first floor of a bigger one.
The hunt for the next emerald moves into the sun. They clear spawner after spawner, find emeralds in the walls that don't count, and keep ending up back in the big bad room.
Basket carries the outside battlements past an unbuilt building, swaps the fence corners for slabs, and works the pattern up a slope and around the far side of Basket Castle.
