Chu Worms are enemies from The Legend of Zelda: Twilight Princess. These bug-eyed, insect-like creatures are found in both the Lakebed Temple and the Cave of Ordeals. Chu Worms are surrounded by a liquid bubble that renders them invulnerable, so Link must either destroy the bubble or remove the Chu Worm from it in order to defeat it. A Bomb Arrow achieves the former, while the Clawshot accomplishes the latter. Once bereft of its protection, a Chu Worm can easily be defeated with four swipes of the Master Sword.
