Hector has head lice. As the authorities don't take the problem seriously Drix and Ozzy fights the lice on their own outside of Hector.

As Hector finds a stray dog outside, an allergen is wrecking Hector's insides. The size changing allergen alternates between a huge monster and a meek guy. At the same time Drix finds a pet dog cell of his own.

Drix is getting tired of having no street smarts so he hires a teacher. The problem is who he chooses as his teacher, a criminal.

Ozzy, Drix, and Maria commandeer a submersible police craft into the intestines to stop a gas build-up that threatens Hector's social situation and infects him with gastroenteritis. Maria is desperate to stop the build up because one gas attack Hector had killed her father and she is determined to avenge him. However, the Rota Virus captures her and ties her up with rope and struggles to get free.

Hector has been hanging with the cool kids at school and tried smoking. This has brought in the addictive Nick O'Teen and his associates who want to enslave all cells in Hector.

Hector eats a tainted corndog from the rusty dog stand and gets salmonella. Now Ozzy and Drix have to save the day and the mayor from the toxic germ Sal Monella.

Strep-finger is back and he has a surprise for Ozzy: a parasite that grows inside him.

The Mayoral election is coming up and Spryman's opponent, a brain cell named Sylvian Fisher, is using a secret growth formula in order to cause destructive unnatural growth spurts and hurt the Mayor's image. Ozzy and Drix must stop this plan, which becomes more difficult when Sylvian takes the growth formula himself and becomes a raging and muscular monster.

Hector has been eating lots of sweets lately, causing his sugar levels to go out of whack. The energy dip afterwards has left all cells sluggish. At the same time, a large amount of bacteria has grown from all the sugar and have been raiding the sugar supplies.

Hector has been having a nightmare each night for a while. Ozzy and Drix has to prove themselves worthy to enter Hector's dreams and put an end to it.
