History Recap / ThePowerpuffGirlsS4EP8

* TheWormThatWalks, mixed with CombiningMecha: When it’s clear they are losing to the girls, the remaining nanobots form into one gigantic (compared to the girls anyway) robot.

* NoEnding: Well, the nanobots are still defeated, but episode simply ends while the girls are still shrunk, and Townsville practically more damaged than it usually ends up.

* TheWormThatWalks, mixed with CombiningMecha: When it’s clear they are losing to the girls, the remaining nanobots form into one gigantic (compared to the girls anyway) robot.

* ItCanThink: The nanobots, prior to engaging the shrunken girls in battle, seemed to be mindless drones that only sought to multiply by consuming carbon. But as more and more of them are destroyed by the girls, their attacks become more coordinated until they fuse into a single monobot to kill them.

* AlwaysABiggerFish: The professor gets to play this role. In the climax, the nanobots combine into a single robot that is many times larger and stronger than the now shrunken girls, but still very tiny and fragile compared to a regular sized adult human. The professor simply flattens him under his foot.
* TheEndIsNigh: in the intro, we see a man with a sandwich board reading “Dark Days Ahead”. When a looming shadow envelopes Townsville, his sign changes to "Told You So."
* TheEndOfTheWorldAsWeKnowIt: what professor Utonium predicts will happen if the nanobots are not stopped.
* FunnyBackgroundEvent: while the girls are hypnotized by the tv show they are watching, the professor (whose clothes are being eaten by the nanobots) runs back and forth screaming in the background.
* GreyGoo: the nanobots destroy everything made of carbon, quickly ‘melting’ away Townsville, and use the material to make more of themselves.
* HoistByHisOwnPetard: When trying to take out the girls the nanobots concentrate their entire number into one giant monobot. However through its giant to the girls it's only a few inches tall to the rest of the world, and now that its big enough to see the professor can easily crush it with his foot.
* IfMyCalculationsAreCorrect: said by professor Utonium during his brief lecture about the nanobots. And unfortunately for Townsville, his calculations that millions of nanobots are now raining down on the city IS correct.
* IncredibleShrinkingMan: in order to fight the nanobots, the professor shrinks the girls down to their size.
* NakedPeopleAreFunny: during their first attempt to fight the nanobots, the girls end up naked since the bots eat away their clothes. Earlier, the professor also had this happening to him.

* SceneryCensor: When the girls return home naked after their first failed attempt to defeat the nanobots, the Professors arm covers up everything from the front, and Blossom's hair covers up her behind (Bubbles and Buttercup use [[HandOrObjectUnderwear their hands]] though.
* ShoutOut: the title is based on Film/NanookOfTheNorth.
* TheSpook: we never learn who made the nanobots or where they came from.
* TheWormThatWalks, mixed with CombiningMecha: when it’s clear they are losing to the girls, the remaining nanobots form into one gigantic (compared to the girls anyway) robot.
