Grumble

Commentary:

The first appearance of the BOXES. Or CUBES. Or something.

Also some crazy ramblings written in Monochrome. The person who did this worked for Black and White before Red. Maybe everyone in the town used to work for them, before they all mysteriously disappeared. Or maybe Black and White just added a lot of machines to their factory to paint all their cubes for them while the other jobs were done by zombie clone monsters.
