Bad Eggs

Although it spends most of its life basking on the tropical beaches of Tropical Beach Planet 42B, the Copperhead’s Sandcow returns to space to lay its eggs. These eggs have the distinctive property of being much more lethal and explodey than typical eggs. For that reason, empty space cubes that lie near egg-filled space cubes are marked with the total number of adjacent cubes (orthogonally and diagonally) that contain eggs.

A 10x10x10 area of space that’s been so marked has been broken into eight 5x5x5 octants, each of which has then been broken up even further. Reassemble each octant, then put the whole shebang back together. The central hub of the 10x10x10 region is shown here; these two slices are parallel (such that the cube marked with the 10 goes in front of the cube marked with a 9).

Once you've reassembled the original area of space, consider what you have created and this will reveal the copperhead's sandcow's final directive to you.

Octant A

These planar sections are correctly oriented with respect to one another. They just need to be stacked in the right order.

Octant B

These planar sections are not correctly oriented with respect to one another; some of them have been rotated. Twist them back and stack them up.

Octant C

Five of these planar sections are real, and are correctly oriented with respect to one another. Discard the four fake ones and stack up the real ones.

Octant D

These planar sections are not correctly oriented with respect to one another; some of them have been rotated. In addition, five of them are real, and the other four are fake. Discard the fakes, twist the real ones back, and stack them up.

Octant E

These ten sections are all correctly oriented with respect to one another. They just need to be reassembled and stacked in the right order.

Octant F

Likewise, these ten sections are all correctly oriented with respect to one another. They just need to be reassembled and stacked in the right order.

Octant G

The ten large sections are all correctly oriented with respect to one another. They need to be reassembled and stacked in the right order around the spindle piece shown on the left.

Octant H

These planar sections are correctly oriented with respect to one another. However, each number has been replaced with a letter using a simple substitution cipher. The cipher is consistent throughout all the sections. Solve the cipher and stack them up.
