Just the difference between the animatronic design and the anthro animatronic design.And sure they are still a animatronic on the anthro design,But the difference between the two is that the endo skeleton isn't visible(It is visible for the withered animatronics,The phantom animatronics,Springtrap,The nightmare animatronics,Ennard[For the obvious reason],The twisted ones,And any other character[s]who happens to have some of they're endo skeleton showing...Oh and endo doesn't count because he really wouldn't look different)

And the sure both of them have blood but the anthro ones don't have oil.
