I have no idead why. But if you get a higher level moschops and train it a bit, then you can make the ultimate battle creature. I have a level 175 with 15k health and over 1000% attack damage. It does 380 damage a hit and can easily kill a bronto
Moschops on passive: A happy camper :)
Moschops on neutral: Peaceful but runs away when attacked.
Moschops on Assist: Normally happy but gets scared and runs away when it sees a fight between either it’s owner or another tamed animal.
Moschops on Aggressive: I am scared of everything that moves :(
