Randomly, I remembered this last night when I went to bed and it disturbed me.
Back in the early 90's, The Adventures of Tintin had a cartoon series running on HBO, and since I usually didn't have that channel, I only caught a few random episodes in hotel rooms when I was traveling.
One episode had this old rich businessman-looking guy who wanted this cursed gem from some aztec temple and finally got it. TinTin and a bunch of other people were trying to warn him about the curse, and he wouldn't listen. So they all pitched tent at the guy's house to try to keep him safe one night (I guess it was one of those one-night full moon curses.)
While everybody was asleep, some decayed mummy in aztec jewelry quietly sneaks in through a window, tiptoes into the guy's room and steals his soul, then disappears back out the window with the gem. After hearing shouting, everybody runs to his room to find the guy dead.
It creeps me out to this day, because of how subtle and decayed-looking the thing was. Think Re-Dead from Zelda with gold jewelry.
