For early game noobies, this little guy has many uses, easy to tame, detects the weather change, and is a small packpack ruducing see it weight. Also if you are not looking to tame one, they seem to be good sources for hide early game, often giving more than a parasaur from my experience.
DO NOT believe that this reduces weight on its inventory. As of today AUG 2020 I tested stacks of meats and berries etc, IT DOESNT. But instead it increases spoil timer of foods, meats and berries on its inventory. ⬆️ to prevent ppl from false informations!
Warns you what storm is coming, and when. If it makes a chirping kinda noise it the sky, it's a sandstorm. If it tries to bury it's head in the ground and shakes it's head, it's a superheat. If it shakes it's tail and growls, it's a lightning storm.
