The dancing gnome glitch is a glitch in Harry Potter and the Chamber of Secrets for PC that allows the player to stop a gnome in motion.
- Let a gnome steal some Bertie Bott's Every Flavor Beans from you.
- Cast Flipendo on it so that the beans fall to the floor.
- Cast Flipendo again on the gnome and make him land on a bean.
He will now run in place in different directions.
It is easiest to perform this glitch in the Diffindo Challenge, as gnomes are in abundance at a point there where there is a lot of space.
