Mr. Alexander

Mr. Alexander is the person who moved into the Snella's old house. In Cabin Fever on page 68, Greg explains that he must have not worn braces as a kid, so his teeth aren't very straight. But during Halloween, Greg's dad went to Mr. Alexander's house and thought his teeth weren't real he said "Ha ha! Those teeth are HILARIOUS!", Mr. Alexander got angry and slammed the door at Frank's face.
