The boy named Steve who stole Arnold's ball in the episode "The List" is in the park just before Arnold gets Rhonda and Nadine back together. This is archiving footage from that episode.
It is shown that Arnold may have arachnophobia.
This is the first episode where Pheobe has a role without Helga, who has no lines.
Helga is the only main character who doesn't speak in this episode.
Moral: Never take your friends for granted.
Irony: Rhonda and Nadine both disagree on each other's idea of what to their report on based on their interests. At the end of the episode when they reconcile, they combine both of their ideas by doing a bug-themed fashion show.
