Addendum 4364/1: Surgical operations to view the stomach of SCP-4364 were conducted on 01/██/2018. It was discovered that SCP-4364 lacks a stomach and instead has a circular opening of immeasurable depth only visible from the inside of its body. A small depth tracker was dropped into the cavity. At the time of writing, the tracker has fallen to 2347 meters deep. Scar tissue from the operation that passed through SCP-4364's stomach tattoo is not visible.
