Twilit Carrier Kargarok

This creature appears when you first need to go to Zora's Domain. Fyer spies a Shadow Bulblin nearby on the lakebed, who then uses a patch of Hawk Grass to summon a Shadow Kargarok, which it then mounts.

To attack, wait until the bird gets close to the ground and then jump on it. Press A rapidly to bite the rider. Do this several times to defeat it. Once the rider is dead Midna will take control of the bird so that you can fly to Zora's Domain.

It should be noted that this enemy is similar to Evil Eagle from Link's Awakening since the rider hops on the bird and it is defeated the same way.
