SCP-5179

scp-5179 class: keter
scp-5179 is a 10m by roughly 10 m broken down fairground ride with the appearance of a duck made of a strange plastic like material , the scp in question appears to be extremely intelligent as it managed to escape from 3 different containment cells.
abilities: scp has high intelligence far beyond human iq, scp apears able to emit a high frequency call that makes anyone who hears it bleed from the ears and die exactly 8 days later from blood loss despite any treatment the victims will always die within 8 days even if it makes no sense for them to die medically speaking it is unknown as of this report how this ability functions, it also has incredible resistance to basically anything thrown at it except some forms of light or radiation.
the scp was found abandoned at a local fun fare tough the owner and staff have no recollection of it being on the grounds prior to the scp containment team that successfully moved it to containment room 1079.
wile contained within said room, it displayed a dormant like nature for exactly 8 days, after this period any d class personnel send in had there ears bleeding till they die or where cleaned from the floor from the creature feeding on them, shortly after the scp was found to have broken its containment with almost no explanation of how exactly it escaped, so it was moved to a new more secure room with a larger area, more guards and cameras however the same pattern emerged and after yet another 8 days it yet again escaped on the 9th day somehow killing almost all the guards and disabling the cameras, the third and final time it broke containment was in a highly secure underwater containment box, with a ton of electric fences around it wile at a depth of around 200 underwater and was also surrounded with sea mines and scuba divers armed with tazers this time on the 9th day it broke its box, killed all divers with ease, disarmed the fence and managed to escape again.
after this we had 2 options we could move this to somewhere else abandoned and hope it didn't escape out into the wild or we could try everything on this thing till something stopped its pattern witch we had already exhausted a number of weapons' and tactics, well it currently sits dormant in a much smaller 120m by 150 m room, the room is kept constantly radiated by gamma radiation and the room must remain at a perfect medium level of said radiation and there are lights emitting 1 of every kind of light type pointed at the scp the scp is now dormant after day 9 and so we believe the scp is perhaps attempting to absorb energy from light or natural radiation in the air to possibly make itself animate and so when bombarded with lots of different energy sources it cant animate itself.
