Ozzy and Drix (2002-2004) is an animated spinoff from the movie Osmosis Jones. Ozzy is a white blood cell who recently moved to the "City of Hector" (they were still in Frank at the start of the series but a mosquito bite while fighting a virus transferred them to a new body) and now fights cri—uh, illness—with his partner and friend, a pill named Drix. The show is Edutainment, but does so in a way thats not too preachy and keeps the action feel of the the movie. Each episode covers a topic of health and safety such as cavities, flatulence, or nicotine dependency.
Tropes the series has:
All Animals Are Dogs: Dander, who is, in this case, a dog germ. From an actual dog.
Bratty Half-Pint: Mayor Spryman is a stuck up punk, though he runs a teenager's body so it's justified. Probably represents Hector's current egoist mentality.
Lethal Chef: Hector attempting to cook breakfast for himself gives him two tapeworms!
Those weren't tapeworms- they were a male and female trichonellis spiralis. Tapeworm infestation only saps nutrients and obstructs the GI tract, but Trichinosis attacks the muscles, including cardiac muscle.
Mr. Seahorse: Subverted. Ozzy initially thinks he's pregnant (and is oddly happy about it too), but it turns out the "baby" is actually a parasitic virus that's been injected into him.
The Smurfette Principle: The proportion of characters' gender is justified as most characters are male because Hector is male; during an episode taking place within a girl's body, the reverse is true, and laws, norms, etc. are stereotypically feminine (such as a law against burping).
Snap Back: The film the series is based on ended with Frank learning to live healthier, as well as Ozzy getting together Leah. By the show's first episode, Leah has vanished and Frank is a slob again. Depressing.
Space Whale Aesop: Since poor health choices are usually a gradual process, they would usually speed up the consequences of the kid's decisions radically. Leading to episodes with morals such as "If you spend one afternoon eating chips and not exercising, you will get fat and nearly have a heart attack."
Spinoff Babies: Sort of? The Movie took place in an older man's body, but the series is moved to a teen's, most likey to be more "kid-friendly."
And added compatibility with the Very Special Episode. Actually not a bad way to show the negative effects of smoking, allergies, etc on the human body. Or at least far more entertaining than most.
If you don't push the metaphor too hard, it even makes sense that Ozzy would bring a veteran's knowledge of police work along to benefit the rookies in Hector's body. The immune systems of adults have usually developed a resistance to infections that kids' own defenses haven't yet learned to fight.
Or even needed to fight, as evidenced in the pilot episode with Scarlet Fever.
Chief Gluteus calls him "incompetent" during his reelection.
Stock Footage: Some clips from the movie can be seen in the show, and it isnt that hard to see it.
"Aunti Histamine" features the runny nose sequence.
Ungrateful Bastard: Mayor Spryman, Ozzy saves his ass more often then not and the little jerk can't even give a "thank you".
He even punished Ozzy, Drix, and Maria for trying to vote for his opponent in the election. He may have done the same for Gluteus for calling him "incompetent".
