The Hunchback is considered by fans one of the most irrepressibly kind characters in the series, and his and Courage's friendship despite how much everyone (especially Eustace) beats down on them is likewise one of the most wonderfully idealistic and heart-softening plots the series has. The episode also introduces this theme, which afterwards is almost always used in the series' most heartwarming friendship moments (such as in "Robot Randy,")
Classical music is heard throughout The Gods Must Be Goosey, as background whenever the Goose God speaks. Specifically, "Symphony No. 40 in G minor, KV. 550" by Mozart and a moment of Wagner's "Ride of the Valkyries".
Eustace doesn't use his mask to scare Courage in this episode, instead he used a similar method to the Tex Avery cartoons.
One of the few episodes where the monster is the protagonist.
Based off The Hunchback Of Notre Dame.
