Yes Scp 173 will definitely kill each other if you break your neck. In SCP Foundation, there is a peanut named SCP 173. Because of its lovely appearance, it is extremely dangerous. Just look at it and twist your neck in the blink of an eye. SCP 173 is very popular, but in fact, the originator of the real neck-twisting horror statue is The Weeping Angels, and The Weeping Angels's number in SCP Foundation is SCP-CN.
