Shadow Kargaroc Rider

From Zelda Wiki.org

Twilit carrier Kargorok
Game(s)	Twilight Princess
Dungeon(s)	Lake Hylia (Twilight)
Weakness(es)	Rider (Wolf Link's jump attack)

This creature appears when Link first travels to Lake Hylia. Fyer believes it was a customer at first, but then realizes it as a 'Monster'. The Bulblin nearby on the lakebed 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 she and Link 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.
