I'm trying to remove someone's intestines, but I can't figure out how. I can cut the small intestine on the left and the large on the right, but pulling on the large intestine doesn't do anything, and I can't grab the small intestine. I've tried cutting everywhere, but I don't see any new spots to cut and that makes him die fast.
Are there other requirements before I can take them out? If so, what are they?
