Synopsis:
Buffy , Willow and Xander are recruited by Principal Snyder to trick-or-treat with the neighborhood kids, but the night doesn't turn out as they had planned when Buffy's costume causes her to lose her slaying ability and the other kids transform into their costume characters. Meanwhile, when Giles begins to paste together the night's events, he learns that it's his past that is making this a very haunted Halloween.
