For me this thing in cute form almost looks like Jerboa, if he eats element and you are low lvl. Turn around and RUN AS FAST AS YOUR LEGS CAN GO (Or jump onto parasaur or galimimus) Otherwise this creature is super cool.
Having trouble finding these fellas? Go to the blizzard area on the east side of snow and you have 2 easy options;1. Wear a tek helmet and enable nightvision and creature sensor for easy finds(nightvision darkens screen) or if you dont have a tek helm use rare mushrooms for blindness to darken screen and use a bloodstalker. Hope this helped and happy hunting!
