This thing got the same base stats of the rex, it's just a smaller and fluffy rex that has a buff roar and a debuff roar, you can literally skip the rex unless you want the tek rex or the tek saddle but you'll have to do boss fights for the tek saddle, but I still think the Yuti is better unless you put him against a tek rex, anyways you can just try to skip the rex and tame this also because it's a big fluff alpha dodo
