Casper wants to find a friend and discovers that on Halloween Eve, he can blend in with all the kids in costumes trick-or-treating. All goes until well until he's discovered as a real ghost and scares both kids and neighbors. So Casper heads off to a Halloween party and dances up a storm with a young girl in costume named Lou. When all the guests get wind of the real ghost, everyone scatters except the little girl- who turns out to be a ghost herself!
