Gleeok (Oracle of Seasons)
Gleeok is a boss that is encountered in Oracle of Seasons. Being a two-headed dragon, it is the boss of Explorer's Crypt, the seventh dungeon in the game, and can be found on the first basement floor.
When Link enters the room, Gleeok is situated at the top of the room, between two patches of spikes. At the beginning of the battle, Gleeok attacks Link by shooting fireballs out at him that do half a heart of damage to Link. He can dodge these by using the Roc's Cape to jump out of the way when Gleeok breathes out the fire. Occasionally, it does not breath out fireballs at Link but summons four fireballs that surround him. In order for him to defeat Gleeok, he must sever both of Gleeok's heads. Link can do this by using the Sword to attack its heads, or he can throw Bombs at their head. Once the first head is detached, it flies around the room and attacks Link. If he does not sever the second head quickly enough, the first head will reattach to Gleeok and Link will have to sever the head again.
After both heads are destroyed, Gleeok is reduced to a skeleton. Changing its strategy, Gleeok's body attacks by jumping into the air and landing onto the ground, causing the floor to shake and stunning Link for a few seconds if he is on the floor. After landing, it then charges at Link. For this phase, Link must use the Roc's Cape in order to be off the ground when Gleeok lands to avoid being paralyzed. Link can then move out of its way and attack Gleeok. Once Link defeats Gleeok, he is rewarded with a Heart Container and the seventh Essence of Nature, the Seed of Life.
