Description:
SCP-5932 is a large mammalian creature spanning up to 3 meters in height and 4 meters in length. SCP-5392 is a quadruped with dark green hair resembling grass. At the top of SCP-5392 head are two large horns resembling the horn of a bull, along the spine of SCP-5392 are 15 spines of white coloration extending to the tail. SCP-5392's eyes are red in coloration with black pupils. The feet of SCP-5392 have 4 spines in white coloration protruding out of the front of SCP-5392's feet in the form of claws.
When aggravated, SCP-5392 will begin to violently swing its tail. The spines begin to secrete a clear non-viscous liquid if this liquid comes in contact with organic matter the organic matter immediately starts to decompose. If a spine of SCP-5392 breaks the skin of a living humanoid the liquid will begin to travel quickly to its vital organs and kill the humanoid within approximately 15 minutes after injection. There is no known cure to SCP-5392's liquid.
Addendum 1
4 D-Class personnel was sent into SCP-5392's confinement to collect the venom. The personnel tranquilized SCP-5392 and locked down SCP-5392's tail to attempt to milk it like one does a snake, this proved to be futile and it became abundantly clear the only way to collect the venom was through aggravation. Doctor Veroeven decided to select one of the spines to collect from and put a container made of Raut Iron to contain the liquid. when SCP-5392 woke up one of the D-class was instructed to taunt SCP-5392. SCP-5392 started to become irritated and started to slam its own tail in an attempt to free itself one of the chains securing SCP-5392's head was not properly secured thus leading to SCP-5392 breaking loose, escaping containment and killing 42 personnel in its rage, the foundation got SCP-5392 under control and back into its containment.
Addendum 2
In an attempt to make an antidote for SCP-5392's venom, the bodies killed by SCP-5392 were examined and found trace amounts of the venom in the subject's system.
