A canine Furry monster, whose name is Dollhouse, and whose nickname is Doll.
A stuffed animal with a will. The cause is unknown, but it is probably some kind of curse or witchcraft.
His personality is cheerful and friendly, and he is also a screw-up and a coward. He thinks of himself as a normal animal even though he is clearly abnormal in many ways. For this reason, he rents a rundown apartment and tries to live in a normal way, blending into society and building normal relationships. He is unaware that he is a monster, so he is afraid of ghosts and Wolfscuro, who appears frequently.
When he is in his plush form, he has no skeletal structure, so he can hardly move.
He responds to pain and temperature, but he doesn't really have those sensations. It is a false sensation, because he himself thinks he is a normal animal. (This is why he is completely oblivious to unexpected wounds, no matter how serious they are.)
He and other monsters like Wolfscuro have a state of being "half-living," in which the boundary between living things and non-living things exists in a very vague form. For example, they can eat even though they are machines, bleed even though they have no blood vessels, and have body heat. In common, the fatal weaknesses of living things are not reflected. For example, destroying the head or cutting off the neck does not cause any damage.
