To those of you who keep saying this.
He is not wearing Catnap's skull nor is he wearing his ribcage. First of all the skull is WAY too big to be a human skull inside Catnap's head, it's to small to actually be the mold right under the fur, AND CATNAP DOESN'T HAVE TEETH, DOES NOT HAVE A FULLY CIRCULAR HEAD, AND HIS SMILE ISN'T EVEN THE SAME SHAPE! Secondly, for the ribcage. Prototype is with it AND his face in Mob Entertainment's Wrong Side Out music video, in which he is in the same scene where you can see Catnap ALIVE.
So to everybody saying that he's wearing Catnap's skull and ribcage, SHUT UP ALREADY.
