They are the best creature for the artifact of the massive or lava cave. I went in there with my terror Bird and it was easy because I could glide across gaps and I was also fast enough to outrun most things in the cave. And my terror Bird was fully mutated so I was also able to kill the majority of the things in there.
YALL WEREN’T LYING ABOUT THE GLIDING ABILITY- it’s little wing flapping😭😩 they’re not bad, they do have little stamina and don’t do much damage but they’re quick so I would only recommend for short travel also the amount of time they can Glide depends on their stamina too so be careful. -V
