+** --- Part Two ---
+As you watch the crane operator expertly rearrange the crates, you
+notice the process isn't following your prediction.
+
+Some mud was covering the writing on the side of the crane, and you
+quickly wipe it away. The crane isn't a CrateMover 9000 - it's a
+/CrateMover 9001/.
+
+The CrateMover 9001 is notable for many new and exciting features: air
+conditioning, leather seats, an extra cup holder, and /the ability to
+pick up and move multiple crates at once/.
+
+Again considering the example above, the crates begin in the same
+configuration:
+
+#+begin_example
+    [D]
+[N] [C]
+[Z] [M] [P]
+ 1   2   3
+#+end_example
+
+Moving a single crate from stack 2 to stack 1 behaves the same as
+before:
+
+#+begin_example
+[D]
+[N] [C]
+[Z] [M] [P]
+ 1   2   3
+#+end_example
+
+However, the action of moving three crates from stack 1 to stack 3 means
+that those three moved crates /stay in the same order/, resulting in
+this new configuration:
+
+#+begin_example
+        [D]
+        [N]
+    [C] [Z]
+    [M] [P]
+ 1   2   3
+#+end_example
+
+Next, as both crates are moved from stack 2 to stack 1, they /retain
+their order/ as well:
+
+#+begin_example
+        [D]
+        [N]
+[C]     [Z]
+[M]     [P]
+ 1   2   3
+#+end_example
+
+Finally, a single crate is still moved from stack 1 to stack 2, but now
+it's crate =C= that gets moved:
+
+#+begin_example
+        [D]
+        [N]
+        [Z]
+[M] [C] [P]
+ 1   2   3
+#+end_example
+
+In this example, the CrateMover 9001 has put the crates in a totally
+different order: =MCD=.
+
+Before the rearrangement process finishes, update your simulation so
+that the Elves know where they should stand to be ready to unload the
+final supplies. /After the rearrangement procedure completes, what crate
