Once, in a coastal area(I don't exactly remember where) I spent half and hour wandering around looking for something, because I swore I kept hearing footsteps! I never found it, if it existed
And another time, I wanted to see how much stuff I could drop before the game crashed and went about collecting clutter, ingredients, and other nonsense, and dropping it in a single room. Later I came back and it was all gone, and there was a bag i the middle of the floor containing all that I had dropped. I later found out this was supposed to happen.
