The Melofors Jinx (Melofors) is a jinx that encases the victim's head in a pumpkin, although it appears to those watching to transform the victim's head into a pumpkin. The pumpkin can be shattered to free the victim, or can fall apart on its own after a short time. Harry Potter, Ronald Weasley and Hermione Granger used this spell on various erklings throughout the grounds of Hogwarts Castle during the 1994-1995 school year, overlooked by their Defence Against the Dark Arts teacher, Professor Bartemius Crouch Jr (who at the time was disguised as Alastor Moody).
