However, it's not for long as once the human grabs his arm and tries to pull him in, Dualscar fights it and tugs his arm back only to bring Cain closer to him. He does this so that he can lower his head down at the same time and use those long, pointy candy corn horns of his to ram into any flesh he can get them into.]
