History Film / Cooties

* DeathOfAChild: One victim ''is'' an infant.

* InfantImmortality: Averted with a ''vengeance.'' Along with all of the zombies being children, a baby is shown being bitten and transformed fairly early into the movie.

** Genderswapped with Calvin, as well as a rare child example.
** Calvin is the only kid left who's not infected by the Cooties in his school.
** He later joins the teachers to fend off the zombies.
** Played much more straighter when the group find another uninfected child, Tamra, although like Calvin she is still a rare example of this trope being used for a characters who's far younger than most examples.
** [[spoiler: Turns out Tamra's immune to the zombifying effects of the Cooties, as she's undergoing the processes of puberty. However, it is never shown or mentioned if Calvin went through puberty.]]

* RealityEnsues: While they have numbers on their side, the antagonists are still ''children'', they are only dangerous when either being ambush predators or in a ZergRush, as shown by Wade being able to rush through them with little difficult in the initial infection scene, and near the end when the adults have some weapons, they are shown to have little trouble taking them down in any mano a mano situation.

* BadassGay: Tracy puts up a good fight against the zombie kids with his improvised jump rope flail.

* TheStoner: The shroom-using bus driver.

* InfantImmortality: Averted. Along with all of the zombies being children, a baby is shown being bitten and transformed fairly early into the movie.

** Especially Patriot, the kid who calls Muslims, "towelheads," threatens to say Clint abused him, and bullies Shelley. When he gets his face impaled at the end, you cheer, especially since he's a little shit as a zombie, too.

* BlackDudeDiesFirst: Played straight with a black male teacher, Averted with the black student Calvin.

* BlackDudeDiesFirst: Played straight with a black male teacher, Averted with Calvin.

* FailedASpotCheck: Wade is too busy shooting hoops to notice children eating teachers ''right behind him''.

* JerkWithAHeartOfGold: See {{Jerkass}} above. Wade is an abrasive asshole whose relationship with Lucy verges ''very'' closely towards abuse, but he's also shown to genuinely love his job as a teacher, care about his peers and have the qualities of a reliable leader.

* BigDamnHeroes: [[spoiler: Wade and Hatachi. With the stoner as the driver.]]

* FinalGirl: Genderswapped. Calvin is the only kid left who's not infected by the Cooties in his school. He later joins the teachers to fend off the zombies. Played straight when the group find another uninfected child, Tamra. [[spoiler: Turns out Tamra's immune to the zombifying effects of the Cooties, as she's undergoing the processes of puberty. It is never shown or mentioned if Calvin went through puberty.]]

* ForceAndFinesse: Wade and Hitachi, the teachers' two strongest fighters, respectively. Wade is a former star football player and human tank, while Hitachi is a mysterious janitor [[AllAsianKnowMartialArts who happens to be a master martial artist]].

* JerkWithAHeartOfGold: See {{Jerkass}} above.

* InfantImortality: Averted. Along with all of the zombies being children, a baby is shown being bitten and transformed fairly early into the movie.

* InfantImmortality: Averted. So, so very averted. One victim ''is'' an infant.

* BadassTeacher: All the teachers manage to hold their own against the students.

* MoodWhiplash: The trailer first plays out like a typical family film taking place in an elementary school, from teachers getting no respect from the students to bullies picking on a girl for her odd blemishes on her face... [[spoiler:until one of them accidentally yanks out a pigtail from her scalp and realizes too late that something is wrong.]]

** Patriot, the kid who calls Muslims, "towelheads," threatens to say Clint abused him, and bullies Shelley. When he gets his face impaled at the end, you cheer, especially since he's a little shit as a zombie, too.

* BastardBoyfriend: Wade acts like this towards Lucy at first.

* JerkWithAHeartOfGhold: See {{Jerkass}} above.
