"Jelly-Legs Curse: Point your wand directly at your enemy and shout Locomotor Wibbly!'"
Vindictus Viridian, Curses and Counter-Curses[src]

The Jelly-Legs Curse,[1] also known as the Jelly-Legs Jinx[2][3][4][5] (Locomotor Wibbly)[1] was a dark charm that caused the victim's legs to collapse[8] as if they were turned to jelly. This spell was covered in Curses and Counter-Curses by Professor Vindictus Viridian.[1]

This spell would have unpleasant side effects if used in conjunction with the Pimple Jinx, namely causing little tentacles to sprout all over the victim's face.[3]

Behind the scenes

  • In the GBC video game adaptation of Harry Potter and the Philosopher's Stone, this spell is used to paralyse the opponent for a near-indefinite amount of turns.
  • When asked whether anything in the series reflects any of her childhood fantasies, author J. K. Rowling says, "...who wouldn't want to be able to use the Jelly-Legs Curse?".[11] This seemingly confirms that it is a curse, rather than a jinx.
  • There have been various mistranslations of this spell's name, such as "Jell-O Legs", "Jam Legs", "Broken Legs" and "Twisted Limping Legs", in the Chinese, Japanese and Vietnamese versions of the books.[12]
