Also known as "The Sandpits of Despair", these are the bunker-dwelling, sand-filled inhabitants of the bunker's darkest recesses. They're a bit of a mystery, but one thing's for sure: don't bother trying to chat with them. They're either too busy playing the trombone or stuck in the sand.
Subrule 4.1: If you must interact with a Sandbag, use a megaphone and a 3-foot-long spoon. Trust us on this one.
Subrule 4.2: In extreme cases, you may need to deploy the Bunker-9000 Sandbag Whisperer 3000. Don't worry, it's just a fancy name for a really loud, really bright flashlight.
