Grotesquely elongates teeth
- "It wasn't a pretty sight. Hermione's front teeth — already larger than average — were now growing at an alarming rate; she was looking more and more like a beaver as they elongated, past her bottom lip, towards her chin — panic-stricken, she felt them, and let out a terrified cry."
Hermione Granger was hit by this spell from Draco Malfoy's wand. Draco and Harry had begun fighting in the corridor, which eventually led to a duel, but the hexes they cast at each other missed and hit Hermione and Gregory Goyle.
Behind the scenes
- The hex is included in the "5 Spell Pack" DLC for LEGO Harry Potter: Years 5-7. In the game, the hex not only enlarges teeth, it also makes the victim wear groucho glasses.
