Episode list

Ozzy accidentally gets transferred into Christine's body when she gives Hector CPR after he jumps off the pool's high dive to impress her. While there, Ozzy starts changing colors and acting feminine and gets arrested because they think he is a virus.

Ozzy is still in Christine; using REM sleep (or Random Eye Movement), he calls Drix for help, which is when he learns he is gender morphing. Upon realizing a cell from a certain gender goes to a body of another gender, that cell becomes that gender, he seeks to escape. With Drix's plan, and the help of another Drixinol cold pill in Christine called "Drixina", Ozzy returns to Hector, and prevents Christine from obtaining pneumonia.

Hector has a skating accident. The brain trauma leads to everyone inside Hector to forgetting who Ozzy and Drix are.

Hector eats an under-cooked chorizo and gets sick to his stomach, leading him to getting two flatworms Trichinella spiralis in his body. The male worm dies, but the pregnant female survives. Ozzy, Drix and a captain must try to kill it before Hector's stomach is infected.

Hector is entering puberty. This manifests itself as an increase in testosterone. The hormone manifests itself as a gang of teenage hooligans who'd rather party than take responsibility. The hormones, lead by the charismatic Shane, has a rather different opinion on how Hector should act.

Maria's brother Ricardo appears. Maria considers him the family black sheep. As he tries to prove himself his past catches up with him.

Hector has a runny nose, so he takes nose spray. The spray manifests itself as Drix's aunt Histamine. She effectively cleans up the snot, but Hector continues taking the spray, making her go nuts.

Hector is super-sizing at fast-food restaurants too much which not only makes him gain weight, but it also gives a cholesterol named Stickety Lipid, the chance to kidnap a fat cell family's child in an attempt to clog an artery. Ozzy and Drix (and the new navigational system, installed by Drix, named Backseat) must return the huge blob to his parents in time. Hector must also get in healthier shape.

Hector is out snowboarding, but gets lost outside in the cold. As if the body temperature loss isn't enough, the cold manifests itself as Cryo, a monstrous beast that shoots cold beams from its elbows.

Hector accidentally inhales paint dust. The dust manifests itself as a team of super villains called the lead heads. To combat them Drix summons The supplements, a super hero team composed of vitamins and minerals.

Ozzy performs osmosis as he sleeps. This leads to the creation of a mutated twin that is all but law abiding.

Billy Blob Bile creates a detour away from the small intestine so bacteria will come to his hotel. Ozzy, Drix, and Maria, who are camping and forced to work at the hotel, must stop Bile before Hector's appendix bursts.

General Malaise escapes from prison and takes over one of Hector's teeth.
