Ensemble Darkhorse: Of all the teens, Trudy gets a good bit of fandom love for her Emo/Goth-like appearance, and for getting a good amount of character development throughout the film (like starting off emo but eventually becoming more of a Perky Goth). Being voiced by Tara Strong doing a variation of her Raven voice also helps.
Hilarious in Hindsight: Fred's childhood camp is named Camp Little Moose. In Mystery Incorporated, Fred mentions that whenever he was bored in his house, he would talk to his imaginary friend, Tyler, who was actually a taxidermy'd moose head.
Suspiciously Similar Song: The song that plays over the end credits is blatantly ripped from "Walking On Sunshine". The 'summertime' song in the middle sounds familiar as well.
