Western Animation: Ozzy and Drix aka: Ozzyand Drix
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.
Concussions Get You High: Averted, in one episode when Hector hit his head skateboarding he displays real symptoms of a concussion such as intense dizziness and confusion, Drix even notes that if Hector DOES fall asleep concussed he might never wake up.
Corrupt Politician: Well, Mayor Spryman sometimes acts this way, but not always. And in his defense, one rival candidate that challenged him was far worse, causing Hector to experience growth spurts on purpose and blaming Spryman for it in order to discredit him, the biological equivalent of political fraud.
Family-Unfriendly Death: Some villains are dispatched in nasty ways. A good example is Scarlet Fever, the first villain, being flown into the spleen and chopped to bits. We even see his remains afterwards.
One-Winged Angel: Scarlet Fever, the first villain, transforms into a more powerful, muscular form after arriving in Hector, where he can spread more effectively.
Only Sane Woman: Officer Tyson is the only cell in Christine who dislikes Ozzy, even though he came from Hector. (Apparently, the cells in Christine's body are inclined to be favorable to the ones in Hector's because Hector and Christine like each other. It Makes Sense in Context, probably.)
Punny Name: Pretty much everyone who isn't human and everything inside Hector's body that wouldn't exist in reality. Puns based on parts of the body, microorganisms, and biology in general, tend to happen a lot.
Recycled: The Series: Clips from the movie are reused, including the runny nose scene, Frank yawning, and Drix dancing in the title sequence.
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). Unfortunately, while the female cells in Hector's body seem to have no problem with it, a male one in Chistine hates his job and actually turns against her, taking bribes from an army of pneumonia-causing bacteria that are planning an invasion.
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."
Actually, in that one episode it was implied that Hector's eating habits were gradually becoming poorer, and he'd been a lot lazier than usual. He'd already been slightly tubby when the episode began.
Speak Friend and Enter: When the characters hosted a contest for Kids' WB!, the answer was to say what color Ozzy would turn on Saturday. The commercial showed a brief animation of what was purportedly a future mid-episode game showing many Ozzy's changing color, so viewers would initially presume that they had to wait until Saturday and watch for that special game. However, several ads showing clips from the new episode had already aired and Ozzy's wording was "what color I turn in the new episode", so a careful listener could send in the correct answer (pink) having already seen it in the ads!
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
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".
Very Special Episode: The smoking episode, though most of the episodes cover something related to health or safety and have An Aesop related to it.
Vile Villain, Saccharine Show: Pretty much follows the movie in terms of how dark many of the villains are despite the goofy tone. The worst is likely Strepfinger, a crimelord who seems to be a streptococcal pharyngitis ("strep throat") bacteria, who's Evil Plan involves launching a parasitic plague on the city using Ozzy as a carrier. (And it's almost successful.)
Weaksauce Weakness: Bacteria can't resist anything sweet, and can be lured into a trap or ambush with simple pastry. (Of course, for a very big bacteria, you'd need a pretty big pastry.) Even the criminal mastermind Strepfinger was apprehended after Maria lured him out of his office with a pie. (After she knocked him out, she said, "You know, for an evil genius, you're pretty dumb.")
The Wildcats: Hector's school nickname. For once, this trope is used without being abused.
