Boggart

A boggart is a shape shifter. It can take the shape of whatever it thinks will frighten us most. No one knows what a boggart looks like when it's alone, because as soon as it sees a person, it transforms into what he or she fears the most.

The charm that repels a boggart is: riddikulus. This charm forces the boggart to assume a shape that the spellcaster finds amusing. The thing that finishes a boggart is laughter. --Moonz 23:37, 14 Aug 2005 (UTC)
