Cars Land is one of the best themed and best storytelling lands Disney has in its portfolio, and that extends beyond just the environment, visuals, and architecture.  It also includes how the characters have their own personalities and can adjust their appearance to suit the season, adding an exclusive flair to the already beautiful and scenic ambiance.  During Halloween Time, Mater, Lightning McQueen, and others dress up in their spooky finest and funnest, showing extra spirit for the fall holiday.  This example of Mater as a vampire is a great one, because it's both unique and instantly recognizable.  The result is a great photo op and a really fun memory!
