Lemme tell you a little something about the Tails Doll. Without his head, he's useless. If you kill him, he dies, and he's vulnerable to fire, blunt trauma, slicing damage, pointy objects, and being jumped on. He's also a videogame character, youknow, the sort of thing with no substance. For him to appear would violate the law of conservation of matter. If you destroy the game cartridge, he dies.
