One of the creepiest things I could make with limited items okay!?
Just imagine...
You are walking through the forest at twilight and you hear a rustling noise. You think it's just a fox. You see a red blur rush behind a tree. Again, probably a fox... But then you notice the red smokey trail. You go to investigate it. You see red smoke behind you. You look fully round and you have THIS THING looking down at you with a BONE in its hand and it's holding THAT WEAPON by your face and it whispers "I'm sorry I have to do this..."
That would be creepy...
Well, anything that sneaks up on you and says "I'm sorry I have to do this..." is creepy! xD
