Alice in Wonderland and Pirate Barely Survive Haunted House on Halloween

I once saw a late 80's or early 90's movie about a group of teenagers who went into a haunted house on Halloween. It was similar to Night of the Demons.

One girl was dressed as Alice in Wonderland with a blue waitress outfit, one guy as a pirate and one fat, annoying guy dressed like a biker.

The annoying guy gets his face turned into a pig by the demon who inhabits the house, and eventually the girl and pirate are the only survivors.

In the end, the guy and girl are trapped in the house and to escape all the friends who have been possessed by demons, they have to crawl over a big brick wall to get away. Once they get to the other side, it looks just like a nice old neighborhood and they run away.

If anyone has the slightest clue as to what I'm talking about, I would love to know the name of the movie.
