Private Investigator's New Kase Extra Yucky Epidemic
Summary: A epidemic of conjunctivitis (pink-eye) has taken several victims. Numbuh 2 must investigate if the cases are coincidental or if a certain nurse is causing them.
- Operative Debuts: Numbuh 41, Numbuh 43
- Villain Debuts: Nurse Claiborne
- Ally Debuts: Joseph "Joe" Balooka (former Hall Monitor. Fired from the force for helping Nurse Claiborne with her foul cooking)
- Starring: Numbuhs 2 and 86
- Cameos: Numbuh 1, 3, 4, 5
- Locations: Gallagher Elementary School
- Villain Technology: Water balloons filled with eye crust virus
- This episode is an obvious parody of the 1973 film Soylent Green. Numbuh 2 is Detective Thorn, Balooka (or Numbuh 86) is Simonson, & Clairborne is Fielding.
- The episode has a darker tone, both literally and otherwise.
- The Nurse's secret ingredient to her Apple Crumbles is eye crusts. As hinted in the last scene of the episode, it seems the filling is mucus.
- Numbuh's 1, 3, 4 and 5 only have minor roles in this episode.
- Numbuh 2 states that a bakers dozen have been infected with pink eye, referring to the fact Nurse Clayborne's apple crumbles as baked goods.
