The Sponge-Knees Curse (incantation unknown) was a curse which presumably made the target's legs spongy, making it difficult for them to walk.


It was used during the September 1999 riot that took place at a Puddlemere vs. Holyhead Harpies match. The Puddlemere supporters used this curse against the Holyhead Harpies supporters in retaliation to the Jelly-Brain Jinx.[1]

Behind the scenes

  • This spell may be achieved by Vanishing crural bones and hence may be a relative of Deboning.
