Gyorm are fish-like enemies with spiked shells that appear in A Link Between Worlds and Tri Force Heroes. These shells act as a defense, and the enemy cannot be attacked while inside of it. Link must use the Hookshot to pull the enemy out of its shell, leaving it vulnerable to attacks. The enemy will attempt to crawl back into its shell if it is not quickly defeated. The empty shell of a Gyorm can be picked up and thrown to damage enemies or activate switches.
