— Vindictus Viridian, Curses and Counter-Curses

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

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.

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?". 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.
