SCP-3108 is a modified Nerf dart gun that displays anomalous properties when firing SCP-3108-1. SCP-3108-1 is a foam Nerf dart. When SCP-3108 fires SCP-3108-1, the anomalous properties occur on whatever is hit. It will "downgrade" whatever is hit, based on the wielder's opinions, and sense of humor. SCP-3108 shows no anomalous properties when shooting any foam dart that isn't SCP-3108-1. It will "downgrade" anything that attempts to disassemble or damage it, seemingly in self-preservation.
