Tame it using a tapi. Get on the front seat, then set your tapi to attack a creature on the ground. Before it attacks the creature, whistle go here toward the Quetzal. From there you can just continue to follow the Quetzal by typing go here while you're tranking it.
The fun way is to jump off and grapple to your argie and whistle it to attack and since argies are slow it won’t catch up in time so tranq till it goes out also bring parachutes and consider liking so more people will know
If you drop a quetzal due to knockout, and it lands next to a giga...just know, the quetzal belong to the giga. Now you get to watch your would be quetzal get eaten by a giga. Now you can go home and cry.
Ive read a few of these tips... Why aren't people using a griffon to shoot from it while flying? I just did that easily they aren't fast flyers. Only downfall was it fell on trees and even after cutting trees down it stayed in mid air... Then for some reason when i need griff to stay stationary while i exit.. It doesnt want to stay still.. And sinomacrops and opening up inventory doesnt work fast enough either lol I just gave up and went to sleep.
