Mom and Dad are worried about their children when they say they’re not scared of the dark. So, they hire a scared Dr. Laxslax (the Red Guy) to solve the problem.
Cow and Chicken’s anarchic cousin, Sow, comes over for a visit. When she comes over to school, Cow ends up taking the blame for Sow’s misguided actions.
Cow has become the most popular student in school thanks to her new glasses. Jealous of this, Chicken decides to get some as well, leading up to an attempt to destroy a new school dungeon (which was actually a new swimming pool).
Cow and Chicken are sent to join the Great Pantzini (the Red Guy’s) circus. He originally has Cow as a trapeze artist, and Chicken as a fire eater, but then settles to have them in as clowns.
