Dancing Feet Spell

Tarantallegra is a jinx used to force another person's legs to begin dancing uncontrollably. It is mainly used to make other people look silly, but can be used in serious dueling to distract someone to gain a strategic edge. Draco Malfoy casts this spell on Harry in Harry Potter and the Chamber of Secrets and Antonin Dolohov uses the spell on Neville Longbottom in Harry Potter and the Order of the Phoenix.
