If you have any dodo arrows, make a trap (tutorials on YouTube) the shoot the quetzal with the dodo arrows. The quetzal will get triggered at you and lead it to the trap. Up vot so dododex can see this
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.
