So now that we have "Caine & Abel" confirmed, I bet the manikin wandering around is Abel (which is why it's allowed to be in the Circus and not confetti'd) and he looks like a plain manikin because the game was abandoned and left unfinished before his design could be made and he could be given any kind of admin powers.
That or it's Abel and Caine stripped him of his powers because he was jealous of him and then the C&A company went bankrupt or something.
