Basically what tRekt6 said, but can you make pressurized bleeding, here's an example: If something sharp is stuck in the doll or somehow a blunt object enters, the longer it stays, the larger the blood loss but there can be a limit. Also if a sharp object enters the doll, little to no bleeding occurs till you pull it out.
