The first time you see one of these, and you're on a flying mount, you just have to fly up to it and do a size comparison for no reason whatsoever. They're smaller than they seem.
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.
