Gleeok, Two-Headed Dragon (氷炎双頭竜 グリオーク Kōri-En Sōtōryū Guriōku?, Double-Headed Ice-Fire Dragon Gleeok) is the boss of the Temple of Ice in The Legend of Zelda: Phantom Hourglass. This dragon has two heads, one ice-breathing and one fire-breathing.
During the first phase of the battle, the heads breath balls of fire and ice. Link must deflect an ice ball into the fire-breathing head and vice versa. This can be done by using the Grappling Hook to connect two of the four pegs diagonally, facing the opposite head of the attack. After a head is hit, both heads submerge and water floods the arena. The water can be evaded by either jumping on a peg or using the Grappling Hook jump. The ice chunks that flow must be attacked or dodged. The small ones can be broken with a single sword strike, the larger ones with two. After three hits to one of the dragon's heads, its armor shatters.
After both heads' armor have been destroyed, Gleeok bites off the two northern pegs. The heads take turns attacking Link, this time coming much closer to Link. The red head breathes a torrent of fire, while the blue head breathes a flurry of ice. When a head inhales to prepare an attack, Link can use the Grappling Hook to grapple to one of the pegs and Gleeok's tongue. The grappled head will be temporarily stunned, allowing Link to attack it with his sword. After both heads are destroyed, Link gains the second Pure Metal, Azurine and a Heart Container.
