When knocking out your first Quetzal it is best that you have a army with good stamina and good movement speed to keep up with the Quetzal. Always remember that the redwood is the worst place to let it fly into because it could get lost or despawn.
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.
