A rainy moon has dark patches of quicksand outside, posing a swift and lethal threat to unperceptive employees. Affected crew mates are slowed down and completely sink in a matter of a few seconds. It is possible for them to escape the quicksand if they get out quickly enough. A quicksand patch looks a bit like a large puddle of darkened dirt on the ground. At night, it can be quite hard to spot.

61-March experiences permanent rain and cannot host rainy weather. Instead, March spawns permanent quicksand patches on the ground.

Strategy: Just walk backwards. There is an audio cue that you enter mud, so walking backwards when it is heard can save you.
