Oh, I just remembered how creepy mausoleum rabbit hole is. The sounds it makes when sim is inside there (fun fact, one sound has been reused in The Sims 4 when Grim Reaper looks through his tablet or sim looks through obituaries on computer) can be creepy.
It not only offers a part-time job, it also lets sims explore the catacombs to find some collectibles (like gnomes). It's a text-based adventure, where your sim can encounter bears (including a zombie bear leaping from a coffin), experience things not meant to be heared by sims, monsters that look like the ones described in fairy tales for mean children, an option to give a skeleon your hair etc. If they encounter a bear or something terrible, they'll come out looking singed without the singed moodlet. What even is happening there? What evils are sealed away there?
Oh, and sometimes I have called the ocean threat in The Sims 4 as souls of previously drowned sims that pull sims underwater for company.
