Good one! The shape shifting salt craving alien monster who “married” a lonely stranded scientist, after she/it killed the man’s wife (by depleting the woman of all the salt in her body through suckers on the ends of the alien’s “hands”).
Just so happens the scientist’s wife used to be a love interest of Bones, the doctor— so the monster appeared to Bones as looking and sounding exactly like the long deceased “wife”.
Star Trek— and they lured the murdering monster in by the husband walking around with a bottle filled with... salt... yelling “ Nancy (her/it’s name was Nancy) I’ve brought salt!!!” Soon to be phasered.
And yes, Moochie looks very much like the alien monster in the story.. when she isn’t emulating a huge “wookie” or Chewbacca!
That was an interesting episode...I was a kid, but I thought the woman who played the salt monster was pretty good looking!
