Barkgrinder (Bunocephalus silvestris) concept

A creature design based in a woodland habitat. Barkgrinder has heavy head and forelimbs, round belly and a very strong fatted tail, a tough guy! Backlimbs? They can help in case of faster walks.
Bumpy keratinous head, extra-strong teeth and a couple of horns allow barkgrinder to eat everything around the damp, his stomaches can digest fruits, weeds, nuts, roots ad of course bark!
The eyes are well protected by thick eyelids, very long cilias, and a splinter-proof membrane.
