One time I hid a bag of vegetables in my filing cabinet and forgot about them. Some time after that I started to smell a mysterious rancid stench. After several days, I searched to find what was behind the horrid odor and found that it was strongest by the filing cabinet, so I opened it and uncovered a bag of liquefied veggies. It smelled just like a dead animal, I didn't know they could get so smelly or that they could just liquefy like that.
That is impressive. I'm reminded of a time of shovel out a potato cellar where many of the potatoes had turned to liquid like that. The stench was intense.
