The Shredder procures an ancient sword of legend. Crafted out of alien metals, this sword is a threat to this dimension and many others.
Tropes:
- Contrived Coincidence: The turtles find the sword when pawn shopping for Splinter right when Shredder was looking for it.
- Dimensional Cutter: How the sword creates portals.
- Fictional Holiday: This episode is set during National Sensei Appreciation Da, a sub-plot being about the turtles trying to find a gift for Splinter.
- Grail in the Garbage: The titular sword, an Ancient Artifact forged from Imported Alien Phlebotinum and holds a lot of historical significance to the Foot Clan, was found collecting dust in a New York pawn shop.
- Rhetorical Question Blunder: Narrowly averted:Vern: What do I look like, a flea?
April: (Covering Irma's mouth) No Irma, don't say it. - Soap Within a Show: A Running Gag has Krang enjoying a hoackie soap opera before April interrupts it with an emergency news broadcast.
- Take That!: The Pawn Shop, which is full of things people don't want, has a massive shelf full of nothing but accordions.
- Void Between the Worlds: Shredder tries trapping Splinter into one using the sword.
