The humor in Episode 13 remains sharp and character-driven. From Principal Ava Coleman’s self-serving antics to Mr. Johnson’s eccentric observations about the animal kingdom, the episode delivers consistent laughs without losing sight of its emotional core. The mockumentary format is used effectively here, with quick cuts and knowing glances to the camera that highlight the absurdity of the situation.

Ava is a character who could easily become a villain in a lesser show. However, in "Zoo Balloon," her cluelessness is played with such joyous obliviousness that it becomes endearing. Her interactions with the zoo staff and her refusal to actually supervise the children ("I’m the idea girl, I don’t do the logistics") highlight the specific frustrations of the public school system without ever losing the show's comedic edge.

The episode’s central conflict is brilliantly simple yet devilish in execution. The school is visiting the Philadelphia Zoo, which naturally leads to a battle of wills over "Zoo Balloon"—a massive, tethered balloon ride that offers a panoramic view of the city.
