When you find one grab an argy and attack it until it flies away, then wait for it to get out of sight then follow it and it will have slowed down and repeat. When it’s dead let it fall and go collect it’s implant then revive it at the revival platform with stone walls and a roof and you got your self a big Quetz
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.
