A Guay from Skyward Sword
Ocarina of Time
In Ocarina of Time, Guays only appear at the Desert Colossus, Lake Hylia, and Lon Lon Ranch during the nighttime. They infinitely respawn, but after a while a Big Guay will appear. It is just as easy to defeat as the other Guays, but it drops more Rupees when defeated.
It's a Guay. You don't know about
Majora's Mask's Guays are similar in look to the ones in Ocarina of Time: purplish bodies and orange beaks. They mostly appear in trees; however, there is a single Guay that circles Clock Town in Termina Field, but it does not attack. If Link plays a certain song with a certain mask on, it will drop Rupees for him. Guays can also be found near the pond in Snowhead region during spring, and also in Ikana Canyon.
Guays take on a different appearance in Twilight Princess, looking more like an actual bird and having more of a twisted enemy design. They resemble a vulture and have bright blue eyes. They usually attack in flocks, but can also be seen by themselves. If Link defeats an entire flock of Guays, they will drop a sum of Rupees.
Target lock: Guay
In Skyward Sword, these small bird-like enemies will dive-bomb Link if they spot him. They also have a secondary ability to drop feces upon Link's head. This creates a noxious yellow cloud that will drain hearts until he shakes it off. When the Guay is defeated, it will drop 5 or 20 Rupees.
