Try making the Quetzal bump to the cliff I think it will be like mission “IMPOSSIBLE” But it turns out I make it bump to the red ob’s cliffs and I knockout it so if you us this tip it’s way easier I guess!
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.
If you manage to knock a quetzal out, try starve taming. If you never tried starve taming it’s just leaving a Dino’s hunger go to half way or lower and then you start feeding. I’ve done this many times and it’s very useful taming trick.
