Dracula:This is how we are represented? Unbelievable.
Every single Tex Avery-influenced animated motion!
The same goes - probably even doubly so - for all the magnificently exaggerated facial expressions throughout the film.
There's one scene during one of Drac's breakdowns in trying to understand Jonathan where he has tiny, off-model, wiggley fingers! Cue laughter!
When Jonathan first comes to the hotel and Dracula is trying to think of what to do with him:
Dracula: I can't kill him. It would set monsters back hundreds of years.
Then, after realizing the monsters are real, Jonathan asks Dracula if they'll kill him:
Dracula: Not as long as they think you're a monster.
Jonathan: That's kinda racist.
There're actually A LOT of jokes lampshading how people react to racism in this film. Drac digs himself deeper while trying to explain to his friends in the sauna why Jonathan "left", only to insult Frank, then Griffin. A scene or two later, Wayne and Murray are mad, though we never find out why.
Another example in that scene is how Dracula offends Griff by saying she would never be interested in someone with such red curly hair, despite being invisible and NO one knowing what he looks like.
Dracula: Well, How was I supposed to know that?!
And there's the Funny Background Event in the sauna. The green blob is sitting behind Dracula when they start the whole racist argument, and once it gets going, the blob's eyes widen and he sinks down like he's really scared and uncomfortable sitting in on this conversation.
Griffin the Invisible Man trying to play charades.
A ghost armor going down from a Groin Attack, despite not actually having privates.
Armor: Why did that hurt me?
The werewolf pups' complete disrespect of their father, Wayne. To the point where Dracula has to outright ask if any of Wayne's children respect their father. And it actually takes Wayne several moments of thinking about it to actually come up with one of them that does.
And then we get that child learning all kinds of impossible details just from smelling a shirt.
Jonny and Mavis' reactions to Dracula's rap near the end of the movie - priceless!
Wayne getting the sheep out of the road during the chase. It's the facial expressions of his friends which really makes the moment.
Wayne: What? You eat lamb chop. It's the same thing!
Wayne's expressions are hilarious too. After spending the whole movie frowning, he sports a huge smile at the sight of the sheep. After eating the whole flock, he gets back to the car and makes a very satisfied face.
