Noggin and Bonce was a shop in Knockturn Alley, specializing in shrunken heads. It had one window facing the street that displayed shrunken heads floating in a liquid. With this Mimblewimble spell, you cause the shrunken heads to be silent! Also known at the Tongue Tying Spell, Mimblewimble makes the victim’s tongue stick to the roof of their mouth for a short while, making it impossible to speak.
You can find the spell casting location, just to the left of the Dystyl Phaelanges window in Knockturn Alley. You can’t miss the shrunken heads inside a shop window.
