Mr. Alexander

Mr. Alexander (known as Mr. Washington in the online version), was a person who moved to the Snella's old house. He doesn't have straight teeth and must have not worn braces when he was younger so he has very unstraight teeth. On Halloween when Frank knocked at his door and he opened, Frank thought they were fake and laughed at them. Mr. Alexander got angry and slammed the door without giving any candy.
