This was when Johnny (a human) entered the monster hotel. Dracula saw it and immediately put him in disguise because he didn’t want any of the monsters to know a human was in the hotel. And plus, he hated humans anyway and he was now talking to Johnny.

Dracula: glares at him Who are you and why are you here?

Johnny: shrugs I’m Johnny and I was just looking for a hotel to stay the night at.

Just then, Draculas daughter, Mavis walked in.
