Exposed mold
These pictures show what could be lurking behind your drywall when constant water spillage is occurring and not being addressed properly.
This Las Vegas business started noticing a really bad musty smell and noticed this portion of their wall was very soft to touch. They called SERVPRO of Centennial Hills to assess what/how this is happening and if we could fix the problem. After probing for moisture we finally found what was feeding the mold it was a tiny leak from their water heater constantly causing their drywall to wicker the water into the walls. Call SERVPRO of Centennial Hills if you see any signs of this happening 24hrs a day, 7days a week.
