Slow-moving aliens from the planet Neptune, wearing nosecone-shaped space helmets, attempt to invade Earth in a winged rocketship. But they are thwarted by a mysterious superhero called "Space Chief," who flies around in a rocket-propelled car.  No relation to Prince of Space.
As with many of the Japanese films used on the show (such as the Gamera movies and Time of the Apes), very young and apparently orphaned Japanese children have unfettered access to all sorts of things that would be completely off limits in America and which, hopefully, are off-limits in real world Japan.
- Many of the invasion scenes in Tokyo were edited from World War III Breaks Out (1960). The appearance of a giant billboard of Adolf Hitler has led some viewers to believe that the stock footage is taken from documentary footage of World War II Japan.
- One of the boys owns a toy Robbie the Robot from Forbidden Planet (1956). 
Segment One: The Bots send the nanites to destroy the mites, scorning Mike like it was his idea when things go south. Meanwhile, The Mad Goth, AKA Bobo arrives, making Pearl and Brain Guy want to commit suicide, until Brain Guy convinces Pearl to save Bobo by telling her that Bobo ruining time and space would mean the end of Chicken in a Biskit.
Segment Two: Mike confuses the bots by telling them about Noh Theater.
Segment Three: Tom comes down with a bad case of Roji Panty complex. Meanwhile, Pearl and Brain Guy unsuccessfully make Bobo remember who he really is.Segment Four: Mike and the Bots are going to lose their sanity when they get a visitor - Krankor!
Closing (Segment Five): Mike and the Bots read suggestions from the suggestion box, all insulting Japan. Meanwhile, Pearl and Brain Guy hit Bobo with a giant slate of rock, making him remember who he is, resulting in him, Pearl, and Brain Guy getting thrown into the dungeon.
Stinger: "Aaaah! What's that?"
- The "Noh Theater" segment is referenced in The Grudge Rifftrax episode.
- This was Jill Roozenboom’s last episode as Production Manager. It was also intern Meshach Weber’s last episode.
- The production staff and cast was extremely disapproving of what appeared to be genuine WWII bombing footage being incorporated into what was essentially a sci-fi film, an attitude that was given free rein in the more-merciless-than-usual riffing. Kevin Murphy specifically cited this as one of the worst movies ever shown on the series, calling the film's director "reprehensible" for using actual WWII footage in what was basically a children's film.
- This episode was ranked #95 among backers of the Bring Back MST3K Kickstarter in the Top 100 Poll.
- A lot of riffs make references to Prince of Space.
Quotes & References
Speed Racer is a 60's anime series about a crime-fighting auto racer (which was a modest success in its native Japan and is actually a much bigger staple of American pop culture, being one of the first imported anime in the country); Shonen Knife is an all-female Japanese rock band; Sailor Moon is an anime about a team of teenage heroines who wear sailor suit-esque costumes (which was a really big deal in both Japan and America, having received two revival series since this episode was made, one live actionand one animated ).
- "It's the Neptunian Bay of Pigs."
A reference to the disastrous failed attempt to invade Cuba and overthrow Fidel Castro on April 17, 1961, as shown in Coleman Francis' magnum opus, Red Zone Cuba.
- "He was trained in karate by Bruce Lei...bowitz".
An implication that Space Chief's karate moves aren't quite as impressive as those of kung-fu movie legend Bruce Lee.
- "Paul is a dead man! Miss him, miss him!"
A reference to the bizarre conspiracy theory that emerged in the late 1960s that musician and member of The Beatles, Paul McCartney, had in fact died and been replaced with a double. The Beatles supposedly "told" their fans this using hidden messages and backwards masking on their later albums. (Paul is Dead) (This specific reference is to the message you can supposedly hear if you play the end of "I'm So Tired" from the White Album backwards.)
- "Thomas the Tank Engine was very cross with Japan and felt he must resort to carpet bombing."
Based on the children's TV series of Thomas the Tank Engine, and another trademark MST3K instance of basing a whole bit around something's vague resemblance to something else. In this case the Neptunians' ship.
- "Enjoy music from "Triumph of the Will."
Triumph of the Willwas an infamous Nazi propaganda film from 1935.
- Servo:"They took out the Hitler Building! Where's everybody gonna go to see Hitler memorabilia?"

The Magnificent Ambersons was a 1942 film by Orson Welles, starring Joseph Cotten.
- "It's been a hard day's night..."
- Kid - "I want to show you something really big." Mike - "It's Crystal Gayle's curling iron."
Crystal Gayle is a singer known for her extremely long hair.
- "Space Chief is actually Racer X, Speed's brother!"
Another Speed Racer reference. The mysterious Racer X was indeed secretly Speed's older brother. Not so secret to the audience, as the narrator would point his true identity out in every single episode (as Mike does here).

- Crow: All the Hitler rides and games! The Hitler salt and pepper shakers!
- Mike: The great restaurant "The Bunker"! It's gone! You sons of...
- Crow: They blew it up!
- . . .
- Crow: Say, Mike—was there a Hitler Building where you grew up?
- Mike: Not, uh...no. No.
- Crow: Sure?
- Mike: ...Yeah.

- [Another spaceship begins to dive]
- Crow: What next? The Mussolini Mall?
