  • Episode Description
  • Krang and Shredder are working on some super mutagen which they plan on using to create an army of super mutants that will take over the world. Bebop and Rocksteady decide to try the mutagen out on Bebop's pet turtle. The mutagen turns him into an evil Mutant Ninja Turtle, named Slash. When Slash starts destroying the place, Bebop and Rocksteady send him to Earth. Fenton Q. Hackenbush, a developer for Donald J. Lofty, has a plan to do away with the sewer system and build condominiums. The Turtles find out what Fenton is planning and try to stop him. They phone April and make arrangements to meet and talk about Fenton's plans. Meanwhile, Slash is looking for the palm tree from his water bowl on Earth, which is where Bebop and Rocksteady have told him it is. While looking for it, he meets Hackenbush. Hackenbush tricks him by saying he will show him where there are lots of palm trees if Slash will do something for him. Hackenbush tells him that he has to smash the Freedom Bell and everything else along his way. Hackenbush hopes that by having Slash do this, it will make the Turtles look guilty and get them arrested. This will get them out of the way so he can proceed with his plan for the sewers. The Turtles find out from April that Slash is planning to smash the Freedom Bell. When they find him, they discover that they are no match for him. Even though he kicks their butt, they do manage to save the bell from being smashed. Back in Dimension X, Krang and Shredder find out what Bebop and Rocksteady have done with the mutagen and are very angry. They send Bebop and Rocksteady to Earth to get Slash back. Slash finds out that Hackenbush double crossed him and decides to get revenge on the city. He boards a rocket filled with garbage and threatens to crash into the city. The Turtles manage to steal the Techno Wing from Bebop and Rocksteady and use it to stop Slash from going through with his plan. Krang and Shredder open a portal for Slash's rocket to enter Dimension X, but Slash just flies by, dumping all the trash in the Technodrome. After the Turtles tell Mr. Lofty what Hackenbush was planning to do, Mr. Lofty fires him and tells the Turtles not to worry about losing their home.moreless

    Notes (2)

    • Episode included on the Teenage Mutant Ninja Turtles Season 4 DVD release.

    • Slash's appearance is significantly altered from his original design. The evil turtle originally wore a black version of the typical turtle mask and bandanas, and his teeth were sharpened. The Slash in the TV series wears an armored mask, does not wear black, and has two of his teeth sticking out.

    Trivia (1)

    • When Hackenbrush is talking with his men (shortly before Slash shows up), one of his men (the one dressed as Raphael) has his costume's beak turn flesh-colored at one point, with his chin being green at that same point!
