Garahnas are a type of enemy from Majora's Mask.
Garahnas are fish-like creatures found solely in the Great Bay Temple's boss room. This is the only place they are found within the game, and are spawned by Gyorg partway through the boss battle from his mouth. Garahnas also look quite similar to Gyorg, and have the same colors. They are weak foes, and only do a quarter-heart of damage, but can be dangerous in groups due to their speed and persistence. The best way to deal with them is to attack them all at once with Zora Link's electric barrier, or to avoid the water entirely.
