Gyorg (Majora's Mask)

"If you go near it now, you'll be eaten! Aim at it from afar to weaken it."

- Tatl

Gargantuan Masked Fish: Gyorg is the boss of the Great Bay Temple. Gyorg was the source of all pollution of the Great Bay of Termina. Gyorg was able to produce offspring through its mouth. It has incredible jumping abilities and was large enough to swallow a full-grown Terminan or Zora. It had hard, tough scales and armor.

Link defeated it by shooting arrows or Zora Boomerangs at it, and swiming into it with the Zora Shield to hurt it. Like all other bosses, an alternative was to defeat him with the Fierce Deity's Mask.
