# About the pull request

Places a Cabinet on a Wall in the SW Big Red mines.

As evidenced by the below images, we did test it. Oddly enough, the
cabinet was always empty. (Unless the cabinet's stuff was included in a
sprinkle. In which case...Oops? We did check the sprinkle file names,
but none seemed to mention the SW mines.)

# Explain why it's good for the game

Well. It probably isn't. It's an empty cabinet. But it looks nicer now?
