Other mistake: If Bela can smell the humans from the castle during Denny's party, Vlad could easily smell Johnny as a human.
Suggested correction: On what basis? Bela is some sort of bat monster and Vlad is a vampire. Not to mention Bela has some strange idea that there are humans already and wants to find one to prove it. Vlad has no reason to suspect Johnny so he doesn't care anyway.
Plot hole: In the beginning, vampires are shown to be invisible in photos but then they seem to appear in videos like security footage and social media posts.
Trivia: When the movie was theatrically released, in the scene where Dennis is watching the puppet monsters, Cakey originally says "Don't eat all that cake, the worst monster of all is diabetes." However, this line was removed upon digital release due to numerous complaints from audiences. Instead, Cakey says "Don't eat all that cake!" and laughs for the remainder of the line.
Question: The camp guy implied that they have to call authorities. Why is this necessary if Dennis isn't a member of the camp?
