Retik orders Krog to drop an atomic bomb on a crater in order to trigger a volcanic eruption. Krog complies, and the eruption causes torrential rains and flooding which seriously disrupt transportation and defense measures on Earth.
Tom Gregory (Robert Hutton), a Los Angeles-based sports reporter, is flying into L.A. and lands his private plane after a rough descent through some kind of opaque midair disturbance, only to find the airport deserted. He meets Professor Galvin (Robert Burton) and his two daughters, Bonnie (Judee Morton) and Lisa (Susan Hart), who tell him that the city has been overrun by huge, hulking, slime-covered subterraneans called Slime People, who appeared out of the sewers and other underground water concentrations. Appearing out of a strange thick fog apparently generated by a device of their own, they've killed hundreds, possibly thousands, panicked the population, fought the army to a standstill, and have now cut off the city with a wall of solidified fog. The professor's reasoning that salt would be effective against slug-like creatures gives them a weapon against the Slime People. But clearing them all out and freeing the city requires an assault against the creatures' own stronghold, which becomes even more essential when Bonnie is taken prisoner. 
- The producers originally planned to have creatures called voles in the film as well as the slime people. The voles would have been wolf-like animals from underground that had been domesticated by the slime people, but the were left out of the final script.
- The scenes of devastation supposedly caused by the fight with the slime people (shown briefly while the group is driving away from the airport) is actually footage of the Hollywood hills shortly after a wildfire swept through the area.
- The scenes in the butcher shop and freezer were filmed in an actual butcher shop owned by the father-in-law of actor Robert Hutton in Lancaster, California.
- The two bums who appear in the theater are played by Joseph F. Robertson and Edward Finch Abrams, the film's producer and associate producer, respectively.
- Blair Robertson, who was one of the scriptwriters, plays Mrs. Steel in the TV news footage.
- According to director Robert Hutton in a 1989 interview, designing and making the slime people costumes consumed over half the film's entire budget.
- The only film directed by Robert Hutton, who continued acting in England, where he wrote the script for Persecution (1974), starring Lana Turner (because he didn't like cats).
- In an interview, star/director Robert Hutton said that neither he nor the stuntmen were ever paid for their work in this film.
- Susan Hart didn't have to read for the role of Bonnie Galbraith; she was automatically cast on the basis of her attractive looks alone when she showed up for the casting session.
- Because of this film's low budget, Susan Hart was given only $35 to buy her own wardrobe.
- Richard Arlen was originally considered for the role of Prof. Galbraith.
Prologue: Joel and Tom are having a rough morning, but Crow shows up all chipper complete with a "morning poem". Tom follows up that he hates "morning bots".
Joel - cartoon eyeglasses
Mads - screaming cotton candy

- Tom Servo does not appear in the closing segment.
- It was the first MST3K episode (not counting the KTMA era) to feature a color film.
- This is the first episode in which they add a blue tint to a black-and-white movie, presumably to help shadowrama be more visible. It’s a practice that will continue into the fourth season.
- Both inventions are props from Joel’s standup act.
- This is the last episode to air during the 80's.
- "must be the granddaddy of all storms"... It's the granddaddy all right; some really gnarly fog happening. Joel is apparently referencing the indica strain Grndaddy purple which is known to be a quite powewrful "medication". ahem.........why were Joel's eyes always half closed??
- "Well, it's a broken water main Ralphy Boy" - Ed Norton from the TV show Honeymooners: he worked in the sewers of NYC.
- "Oh it's Tom Waits on a bender"....- the blonde guy resembles the American singer/actor
- Bobcat Goldthwait- the screaming guy resembles the american comedians act
- "Hey mikey, she likes it!" while kissing the girl. reference to a classic Life cereal's commercial from the 1970's line said by Little mikey
