The most comfortable SCP that I was introduced to was 999. I was, without a doubt, very very surprised when they shoved me into room (not a cell) and the only thing there was a great big blob of orange slime. Then, it shaped into a jiggling hump. It looked like that guy with one eye from that kids movie. It bounced and then made a mewling kind of noise. I am not gonna lie. I panicked for a quick second and tried to run. But I couldn't go anywhere. And then, it hugged me. Actually, it kinda rubbed against my leg. And for some reason, I wanted to forgive all the scientists for what they did. I wanted to-- hahahaha-- give them a big hug. But there was something about that guy that made me feel better. Made me feel loved.
