Giant bugs are infesting the city of New York, and its all thanks to Shredder and Krang!
Tropes:
- Achievement In Ignorance: Bebop and Rocksteady accidentally create a bug-enlarging mutagen when Krang has been spending all this time trying and failing to recreate the old formula.
- The Bus Came Back: Metalhead and the Punk Frogs (or at least Genghis) reappear in this episode.
