First of all, the Doedicurus is an ancient ancestor of modern armadillos, like the Glyptodon.
Second, in real life, it was quite fast for its size, running at about a good 35 mph ( ARK, start researching properly)!
Third, whoever said that they gather stone yet they CANNOT break stone structures, even I’m puzzled on that one (again ARK, follow common sense!). Thank you for mentioning that🧐!
Not sure where this goes but if u place a spike wall in front of them and when their health is low enough they have to turn into a ball and be stuck in a constant cycle until the spike wall is removed. It's a great way if you find one and want to tame it later. Unless it gets killed by something else while in a ball it should be fine. I stil have one stuck on one of my walls and ima keep it ther until I can tame it for stones.
