Gibo

Gibo or Geebo are rare enemies; strange living bodies of gas that appear in Thieves' Town in. They consist of two separate sections; a red inner nucleus and a star-shaped outer cloud of dark gas. Their movement is unusual as well; the nucleus separates from the inside of the cloud and moves to a new location independently, while the gas then follows. Both sections of the creature are able to cause damage, but the gas cloud is entirely invincible, and provides protection to the vulnerable nucleus. The Gibo is therefore only vulnerable when it attempts to move. Their awkward movement patterns are made worse by their appearance alongside traps such as moving floors, Winders and Bubbles.

Trivia

 * Due to the transparency effect of the Gibo cloud, certain other elements of the game will also become transparent in rooms containing them, such as items dropped by monsters like Fairies and magical effects from the Magic Medallions, among other things.
 * Gibo are sometimes mistaken for Bubbles due to their similar colors and shape.
 * Gibo share some similarities to Morpha from Ocarina of Time, although the Hookshot has no effect on them.
