Bronx does not appear in this episode. The main reason why is that nearly all of Frank Welker's time was spent performing the vocal effects for the Werefox. Despite this he remains uncredited.
During the Halloween celebrations, Elisa is costumed in Belle's gold ballgown, which is symbolic to her and Goliath, a non-human like the Beast, falling in love.
At one point there is a sign for a food court that is misspelled that reads Food Corut, possibly because of a mistaken translation with the Japanese animation.
Xanatos outright states that he and Fox are capable of love; just not with very deep empathy.
The reason that Fox isn't willing to give the Eye of Odin back is because the magic item causes whomever wears it to have a strong desire to keep it.
