Ript and Claude, the stars of this title are two ignorant, belly-scratching, lazy, disrespecting reptiles with no manners, no culture, no socially redeeming value whatsoever...so who better than them to instruct the granddaddy ancestor of us all — the world's first proto-human? Being mentors to the human race is no picnic, of course, and to our two heroes, this little mammal is one big pain in their sphincters.
