Season four of Teenage Mutant Ninja Turtles is split into two sub-sections that aired concurrently: thirteen episodes which aired daily in syndication, and twenty-six episodes that premiered in hour-long double-bills on Saturday Mornings on CBS, which would serve as its home for the remainder of the whole series. A brief "Turtle Tips" segment aired between the two episodes which served as PSA about the environment or other issues. There were a total of 20 "Turtle Tips" segments produced and aired. The syndication episodes featured the original title sequence, while the CBS episodes deubted a new title sequence, and also did away with the show's title cards. During this season, the Technodrome is back in Dimension X, having been launched through a portal at the conclusion of season three. The season premiere, "Plan 6 from Outer Space", aired in syndication, and detailed how the villains' battle fortress crash-landed on an asteroid; in the later episode, "The Dimension X Story" a volcano on the asteroid erupted, immobilizing the Technodrome by surrounding it with molten lava. "The Dimension X Story" was evidently intended to be the first episode of the CBS run, as many other episodes which aired before it from both the syndication and CBS episodes refer to the Technodrome being trapped in lava, but wound up airing very late in the season. Note that the Vacation in Europe episodes take place between the first two episodes of this season. Some episodes from this season were based off titles from other works. "Plan 6 from Outer Space" was from Plan 9 from Outer Space a 1956 film. "Four Turtles and a Baby" came from Three Men and a Baby a 1987 film. "Turtlemaniac" was from Listomania an intense fan frenzy. "Planet of the Turtles", was like Planet of the Apes but with other turtles. "Name That Toon" came from Name That Tune a game show from December 1952 to 1985 in September. "Turtles of the Jungle" had many reference to the King Kong film. "Menace Maestro, Please", Shredder dressed up like the Phantom of the Opera. "Super Hero for a Day" was from King for a Day. "Back to the Egg" was a title from a 70s song.
Plot Synopsis Edit
In the Technodrome, at this point of the series located on an asteroid in Dimension X, Krang is working on duplicating the original mutagen when Bebop and Rocksteady try to stop a fly. The fly lands in the mutagen and it increases in size. Krang and Shredder send the giant fly to Earth via the dimensional portal. Krang and Shredder decide to use the mutagen to create large insects destroying the Earth if the people don't surrender.
Genghis Frog, one of the Punk Frogs, go by bus to New York City to visit the TMNT. When arriving in the city, he sees the huge fly and starts chasing it. Meanwhile, the TMNT are watching TV and see April O'Neil reporting about the giant fly. The TMNT take the Turtle Blimp to check it out. They end up rescuing Genghis from the giant fly.
In Dimension X, Krang and Shredder use the mutagen to mutate three new bugs and send them through the dimensional portal to Earth to keep the TMNT busy while Krang and Shredder work with their plan. Their scheme is to find an ant-hills and use the mutagen on the ants.
New York City is in chaos with the giant insects destroying the city. A mud wasp is building a nest on the Channel 6 building and a giant scorpion attacks the TMNT and Genghis. Just as the TMNT to trap the scorpion with the help of a truck, April radios the TMNT asking for help. Channel 6 are out of power, since the insects destroyed the electrical wiring, and the air inside the Channel 6 becomes tighter. The TMNT rescue April from the mud wasp nest and soon after, the wasp attacks them.
Shredder, Bebop and Rocksteady arrive on Earth trough the dimensional portal and find an ant-hill. Thanks to Bebop and Rocksteady's "incompetence", Shredder accidentally spills some mutagen on an ant before Shredder, Bebop and Rocksteady can run away in safety. However, Shredder, Bebop and Rocksteady manage to escape from the giant ant and then they can return to the anthill.
The TMNT, April and Genghis Frog enter a hangar and borrow an airship, which normally is used at the Thanksgiving Day parade. They also borrow pesticide. The TMNT, April and Genghis Frog herd all the insects together by firing the pesticide upon the insects, but they can't figure out what to do with the insects until they see Shredder, Bebop and Rocksteady. The TMNT, April and Genghis Frog lure the bugs fo follow after Shredder, Bebop and Rocksteady through the dimensional portal before Krang is able to close it in time.
Krang, Shredder, Bebop and Rocksteady end up with the Technodrome with all the insects that they had originally mutated and sent to Earth.
